前段js初学总结

常用的js整理
     confirm("此次修改操作会清空所有基础数据！！！您确定要修改吗？")
       <a onclick="delBasisData(‘${data[‘_id‘]!‘‘}‘)">删除</a>

抑制警告
    @SuppressWarnings(value={"unchecked","unused"})
    @SuppressWarnings("all")

如果为空给一个空的字符串
      ${fieldGroup.name?default(‘‘)}

定义一个事件和方法
       onkeyup=‘valueRFMNum(this)‘

判断是否为空

       <#if fieldGroup.children??>
       ${user!‘your name‘}
       ${user?if_exists}
       ${user?default(‘your name‘)}

进行转换
       <#assign test2 = "2009-01-22 17:23:45"?datetime("yyyy-MM-dd HH:mm:ss") />
          <#if child.fieldFloat?default(0)==0>
  
重定向方法的使用
         function toCustomerGroupPage(id){
              window.location.href="../customerGroup/toCustomerGroupPage?bhCustomerGroupId="+id;
          } 

排序

          <#list list?sort_by("time") as v> 
         </#list> 


集合的循环
         <#assign score = {"语文":78,"数学":83,"Java":89} >
             <#list score?key as x>
              ${x}--->${score[x]};
             </#list>
  
返回的数据使用id 进行一个添加的功能
          $("#div_content").append(‘<ul class="labelEditUl">‘
                        + ‘<input type="hidden" name="_id" value="‘ + _id + ‘">‘
                        + ‘<input type="hidden" name="customerId" value="‘ + data.customerId + ‘">‘
                        + ‘<input type="hidden" name="creatorId" value="‘ + data.creatorId + ‘">‘
                        + ‘<input type="hidden" name="creator" value="‘ + data.creator + ‘">‘
                        + ‘<input type="hidden" name="createTime" value="‘ + data.createTime + ‘">‘
                        + ‘<#list 1..30 as i><#if (basisTable[‘field‘+i])??><li>‘
                            + ‘ <span><#if (basisTable[‘must‘+i]) == ‘1‘><i style="color:red; margin-left: -7px;">* </i></#if>${basisTable[‘field‘+i]!‘‘}:</span>‘
                            + ‘<input onblur="checkDataModal(this)" maxlength="${maxLen[(basisTable[‘type‘+i])]}" style="width:200px;height:28px" class="modify_input <#if basisTable[‘type‘+i] == ‘date‘>Wdate</#if>" fieldName="${basisTable[‘field‘+i]}" must="${basisTable[‘must‘+i]}" fieldType="${basisTable[‘type‘+i]}" type="text" name="field${i}" value="‘+ (data.field${i} == "undefined" ? "" : data.field${i})
                            +‘" class="labelInput" <#if basisTable[‘type‘+i] == ‘date‘>onfocus="WdatePicker({dateFmt:\‘yyyy-MM-dd HH:mm:ss\‘})"<#elseif basisTable[‘type‘+i] == ‘integer‘>onKeyUp="disposeUtil.limitnumeral(this);"<#elseif basisTable[‘type‘+i] == ‘double‘>onKeyUp="disposeUtil.limitprice(this);"<#else>onKeyUp="disposeUtil.limitspecialstr1(this);"</#if>>${typeMap[(basisTable[‘type‘+i])]}</li><br><p class="Validform_checktip Validform_wrong" style="margin: -25px 1px 10px 89px;"></p><#else><#break></#if></#list></ul>‘);
                $("#modifyDataModal").modal(‘show‘);

循环功能
        <#list KMFunctionMap?if_exists?keys as key>
        <option value="${key}" <#if (tag.moduleId)?default(‘402893be5507612a01550763306906f9‘) == "${key}">selected</#if>>${(KMFunctionMap[key])?default(‘‘)}</option>
                                    </#list>

动态包含
       <#include "./confirmWindow.ftl"/>
      debugger;
       <#if totalm gte 10000>${(totalm/10000)?string(‘##.#‘)}万<#else>$   存量288.7万人


数据库的更新
             String orgId = getOrgIdByUserByOrg();
            DBCollection collection = MongoDBServer.getInstance().getBaihuiDB().getCollection("goal_count");
            DBObject obj = new BasicDBObject();
            obj.put("orgId",orgId);
            obj.put("goalCount",goalCount);
            collection.update(new BasicDBObject("orgId",orgId),obj,true,false);


获得val值  readonly  只读模式
         1.  <input type="text" readonly  id="goal-input" maxlength="16" name="goal" value="${goalm!‘0‘}">

         2.   $("#goal-input").val(‘${goalm!‘0‘}‘);

                                                 <select class="select" id="findBy" name="findBy">
                                                            <option value="">--请选择--</option>
                                                            <option value="customerId">客户ID</option>
                                                            <#list 1..30 as i>
                                                                <#if (basisTable[‘field‘+i])??>
                                                                    <option value="field${i}">${basisTable[‘field‘+i]!‘‘}</option>
                                                                <#else><#break>
                                                                </#if>
                                                            </#list>
                                                        </select>
         $("#findBy").val()

按钮的功能
          <input type="button" class="btn btn-primary" value="下一步" onclick="nextOperation();">


弹出新的窗口使用  
          1. <a id="goalMember" href="javascript:void(0);">
          2.$("#goalMember").click(function () {
                        $("#goalMemberModal").modal("show");
                       });


          3.<div class="modal fade chartModal" id="goalMemberModal">
         <div class="modal-dialog">
           <div class="modal-content">
            <div class="modal-header">
                <h4 class="modal-title">修改目标会员总量</h4>
            </div>
            <form role="form" id="goalMemberForm" action=‘‘ method="post">

                <div style="text-align: center">
                    <ul class="chartModalUl">
                        <li>
                            <span><i style="color:red; margin-left: -7px;">* </i>目标会员总量:</span>
                            <input type="text" id="goal-input" maxlength="16" name="goal" value="${goalm!‘0‘}">
                        </li>
                    </ul>
                </div>

            </form>
            <div class="newly-down-buttn" style="text-align: center">
                <button type="button" id="save-btn" class="btn btn-success">保存</button>
                <button type="button" id="cancel-btn" class="btn btn-outline btn-default" style="margin-left: 20px">取消</button>
            </div>
          </div>
           </div>
          </div>



非空的校验
         var goal = $("#goal-input").val();
            if (!goal){
                alert("目标会员总量不能为空！");
                return;
            }
			
			
编写一个事件 把表单的内容进行一个提交
		     $("#div_content").append(‘<h3>失败!</h3><span>错误‘+data.error
                                +‘条数据</span><br><a onclick="downErrorList()">下载错误列表</a>‘+
                                ‘<form id="downError" action="../basis/downErrorList"><input type="hidden" name="filePath" value="‘+
                                data.filePath+‘"></form>‘);
								
								
							
提示信息
       confirm("您确定要删除这个分组吗？")							
								
	
用来处理字符串 转化为json的格式
       JSONArray jsonArray = JSONArray.fromObject(tag.getRuleConditions());							
  

ajax里面嵌套 超链接
       $.ajax({
            type:"post",
            url:"../referenceGroup/isLeafNode",
            data:{
                groupId : TgroupId
            },
            success:function(data) {

                if (data == true){
                    document.location.href = "../reference/updatePage?opName=create&groupId="+TgroupId+"&groupName="+TgroupName;
                }else {
                    alert("只有叶子分组才能添加参照表！");
                }
            }
          });

加载和调用前一个路径
     History back() 方法


ajax里面调方法
     function groupExists(groupId) {
        var flag = false;
        $.ajax({
            type: "post",
            url:"../referenceGroup/groupExists",
            data: {
                groupId:groupId
            },
            async: false,
            success:function(data){
                if(true == data){
                    flag = true;
                }
            },
            error:function(){
                errorAlert();
            }
        });
        return flag;
      }

    function errorAlert() {
        alert("抱歉，分组数据与服务器不同步!");
        document.location.href = "../referenceGroup/referenceGroupList";
     }

 $.ajax({
            type:"post",
            url:"../tagGroup/isLeafNode",
            data:{
                groupId : TgroupId,opName:"create"
            },
            success:function(data) {

                if (data == true){
                    document.location.href = "../tag/updatePage?groupId="+TgroupId+"&groupName="+TgroupName+"&opName=create";
                }else {
                    alert("只有叶子分组才能添加标签！");
                }
            }
        });





sql  不等于空
     AND ARG_F2001 <> ‘‘

解析为整数
     StringUtil.parseInt(

本地文件的路径
    String filePath = ApplicationPath.getRootPath() + "uploadFile" + File.separator;


实现文件写入本地的功能
   private boolean createCsvDataFile(int size, Map<String, Long> cardsMap_1, Map<String, Long> goodsMap_1, String filePath, String fileName) {
    String countSql = "SELECT COUNT(ARG_F2001) FROM (SELECT ARG_F2001 FROM bh_custom_module_2 WHERE IS_DELETED = 0 AND ARG_F2001 <> ‘‘ AND ARG_A2001 <> ‘‘) a ";
    int total = StringUtil.parseInt(bhCustomModule2Dao.findBySql(countSql).get(0)+"");
    int loop = total% size == 0 ? (total/ size) : (total/ size + 1); 三元表达式
    String limitSql;
    String countSql = "SELECT COUNT(ARG_F2001) FROM (SELECT ARG_F2001 FROM bh_custom_module_2 WHERE IS_DELETED = 0 AND ARG_F2001 <> ‘‘ AND ARG_A2001 <> ‘‘) a ";

    int loop = total% size == 0 ? (total/ size) : (total/ size + 1);
    BufferedWriter csvWriter = null;
    try {
            File file = new File(filePath);
            if (!file.exists()) {
                file.mkdirs();
            }
            csvWriter = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(new File(filePath+fileName)), "UTF-8"), 1024);
            for (int i = 0,start = 0; i < loop; i++) {
                limitSql = "SELECT ARG_F2001,ARG_A2001 FROM bh_custom_module_2 WHERE IS_DELETED = 0 AND ARG_F2001 <> ‘‘ AND ARG_A2001 <> ‘‘ limit " + start + "," + size;
                ArrayList<Object []> limitResult = (ArrayList<Object[]>)bhCustomModule2Dao.findBySql(limitSql);
                for (Object[] strings : limitResult) {
          Long cardId = cardsMap_1.get(strings[0].toString());
          Long goodsId = goodsMap_1.get(strings[1].toString());
          if (cardId == null || goodsId == null)continue;
                    csvWriter.write(cardId+","+goodsId+",1");
                    csvWriter.newLine();
                    csvWriter.flush();
                }
                start += size;
            }
            return true;
        } catch (Exception e) {
            e.printStackTrace();
      return false;
        } finally {
            try {
                if (csvWriter != null) csvWriter.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
  }



清除集合的方法
    cardsMap_1.clear()

js 标签判断上下页
     function gotoPage() {
        var totalPage = ‘${page.totalPage}‘;
        var pageNo =  $("#commonListTable_input").val();
        if (!pageNo || parseInt(pageNo) > parseInt(totalPage) || parseInt(pageNo) < 0)return;
        queryListDo(pageNo,‘${page.pageSize}‘);
    }
进行一个赋值的操作
             window.tagSearchForm.action="./tagSearchUpdate";
            window.tagSearchForm.opName.value="update";

获得被选中的id 被给一个返回值
function getShareState(){
        var shareState = 0;
       var shareState =  $("#shareState_div").find("input[type=‘radio‘][name=‘shareState‘]:checked").val();
        if(parseInt(shareState)>2){//分配
            shareState =  $("#shareState_div").find("select[name=‘shareState‘]").val();
        }
      return shareState;
    }

首页按钮禁用
     <li class="paginate_button first disabled" aria-controls="commonListTable" tabindex="0" id="commonListTable_first">
                            <a href="#">首页</a> 
                          </li>

搜索清除 回显和确认  recommendResult 页面
    吧搜索的功能里面的信息 进行一个清除的操作    


搜索条件进行一个加密的处理
     base64encode(escape(__ret.operaValues));
    <script src="../plugins/base64/base64.js" language="javascript" type="text/javascript"></script>                      
json的数据的格式
     { "people": [{ "firstName": "Jason", "lastName":"Hunter", "email": "bbbb"},{ "firstName": "Elliotte", "lastName":"Harold", "email": "cccc" }]
       "annimal":[{ "firstName": "Jason", "lastName":"Hunter", "email": "bbbb"},{ "firstName": "Elliotte", "lastName":"Harold", "email": "cccc"  }]
}    


json的转化和解析
   var last=JSON.stringify(obj); //将JSON对象转化为JSON字符


    var obj = str.parseJSON(); //由JSON字符串转换为JSON对象
 
    var obj = JSON.parse(str); //由JSON字符串转换为JSON对象
 

 用for...in 这种遍历的方式，例如：
var arr = new Array("first", "second", "third") 
for(var item in arr) {
document.write(arr[item]+",");
}
Map 循环的方式
Map<String,String> map=new HashMap<String,String>();
    map.put("1","hello");
    map.put("2","name");
    map.put("3","tom");
    for(String key:map.keySet()){
        System.out.println("value值为:"+map.get(key));
    }


重定向
     window.location.href="../customerGroup/customerGroupBaseList?size=${page.size}&number=" + num + "&searchVal=" + encodeURI(encodeURI(searchParams)) + "&pageSign=1&dateStr=" + dateStr + "&orgId=" + orgId;

获得每个某个不认的标签
     $("#tbody-search td").each(function(){
            var oper = $(this).find("select").val();
            var name = $(this).find("input").prop("name");
            var val = $(this).find("input").val();
            var strs = "NULL,UNNULL,TODAY,YESTERDAY,LASTWEEK,THISWEEK,LASTMONTH,THISMONTH";

            if(val!="undefined"&& $.trim(val)!="" || strs.indexOf(oper)!=-1){
                searchParams += ",\""+oper+"|"+name+"\":\""+$.trim(val)+"\"";
            }
        });   
移除属性disabled
     $("#valueRNum").removeAttr("disabled");   

正则表达式替换字符
     paramsJsonString.replace(new RegExp("‘",‘gm‘), "\"")

获取var 集合中某个值
  var paramsJson=\‘‘;
   paramsJson[‘module‘]
 循环集合var的值
      
for(var i in linkModule) {
linkModule[i];
}
     


   遮罩页面实现和结束
   Overlayer.show("正在处理数据，这个动作可能要花费一些时间，请耐心等待！");
   Overlayer.remove();
判断去空格是否为空
   if (nameId.trim() =="") {
    Overlayer.remove();
    alert(‘文件夹名不能为空格‘);
    return false;
     }
三元表达式
  totalElements  != map ? 1 : 0;    
获取当前用户
  User user = UserUtil.getUser();  
系统当前时间
  long nowMills = System.currentTimeMillis();
将字符串进行编码
  txt = URLDecoder.decode(txt, "UTF-8");    
关闭窗口
  window.close()
