应用场景,一般不用于这种用户添加(此处只是示例),一般用于多记录,如学历信息,工作经历等

在这之前,我们要在index.php中引入jquery.edatagrid.js文件,可以去网站下载,稍后也会附出文件以代码的形式;

在前一节中,我们需要修改的有两个地方(优化后的代码基础上),第一index.php页面,第二稍稍增加或者改动userAction和userModel文件;

首先附上index.php代码,然后解释以下:

<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>dataGrid</title>
    <link rel="stylesheet" type="text/css" href="../ui/jquery-easyui-1.4.5/themes/default/easyui.css">

    <script src="../ui/jquery-easyui-1.4.5/locale/easyui-lang-zh_CN.js"></script>
    <!--<script src="../js/crud/bus_pubuser.js"></script>-->
    <script>
    $(function(){
        $(‘#dg‘).edatagrid({
            url: ‘./data/crud/userAction.php?flag=list‘,
            saveUrl: ‘./data/crud/userAction.php?flag=add‘,
            updateUrl: ‘./data/crud/userAction.php?flag=modify‘,
            destroyUrl: ‘./data/crud/userAction.php?flag=delete‘
        });
    });
    </script>
</head>
<body>

页面中table属性要更改,加入属性idField="id" 去除url属性,idField表示指明哪一个字段是标识字段。其中form表单可以去掉不需要弹出形式了;

/***********************/

在table的列中添加如下代码:editor="{type:‘validatebox‘,options:{required:true}}",

editor属性指明编辑类型。当字符串指明编辑类型的时候,对象包含2个属性:
type:字符串,该编辑类型可以使用的类型有:text,textarea,checkbox,numberbox,validatebox,datebox,combobox,combotree。
options:对象,object, 该编辑器属性对应于编辑类型。

/***********************/

在head头部中可以看到,添加了如下代码:

<script>
    $(function(){
        $(‘#dg‘).edatagrid({
            url: ‘./data/crud/userAction.php?flag=list‘,
            saveUrl: ‘./data/crud/userAction.php?flag=add‘,
            updateUrl: ‘./data/crud/userAction.php?flag=modify‘,
            destroyUrl: ‘./data/crud/userAction.php?flag=delete‘
        });
    });
</script>

指定url表示获取用户列表信息list

saveUrl表示新增用户保存动作(支持批量保存)

updateUrl表示更新保存用户动作

destroyUrl表示删除用户动作

在toolbar的按钮变成了onclick="javascript:$(‘#dg‘).edatagrid(‘addRow‘)"等,这些addRow,destroyRow等你可以去js中看或者修改,不然就记住直接使用;

 

准备好之后,还是启用原来的后台代码,list,delete,update,都没用问题,但是add出现了错误,

跟踪代码知道,在add新增的时候,提交post表单的时候有一个新的属性isNewRecord等于true的也被提交过去了(ps,如果在之前的代码中,如果我使用每一个字段都去匹配的话,就不会出现这个问题,但是考虑到如果有很多的字段,你每个都去匹配的话,将会很耽误时间,所以就直接使用$_POST当做数组直接过去了),所以我们需要变更代码;

有两种解决方法,一是,我们直接重新加个flag,比如把saveUrl改成这样, saveUrl: ‘./data/crud/userAction.php?flag=add_special‘,add_special作为一个新的flag传到后台,如后台userAction.php在switch下条件添加case "add_special" : $user->add_special($_POST);  break; 然后在userModel.php新增add_special方法;

方法如下:

function add_special($arr){
            $medoo = new medoo();
            $fname = $arr["fname"]==null?"":$arr["fname"];
            $lname = $arr["lname"]==null?"":$arr["lname"];
            $sex = $arr["sex"]==null?"":$arr["sex"];
            $phone = $arr["phone"]==null?"":$arr["phone"];
            $email = $arr["email"]==null?"":$arr["email"];
            $sql = $sql = "insert into eui_user(fname,lname,sex,phone,email) values(‘$fname‘,‘$lname‘,‘$sex‘,‘$phone‘,‘$email‘)";
            $result = $medoo->query($sql);
            if($result){
                echo json_encode(array(‘success‘=>true));
            }else{
                echo json_encode(array(‘errorMsg‘=>‘操作过程出现错误!‘));
            }
        }

我这里直接每个赋值获取,由于字段比较少的原因(如果字段比较多,大家可以想想其他方法,$_POST提交过来的第一个是isNewRecord,思路是可以去除第一个);

还有一种方法就是,把这个方法直接写在save_user方法下,如下:

function save_user($arr){
            $medoo = new medoo();
            //var_dump($arr);
            if(isset($arr[‘isNewRecord‘])){//可编辑列表
                $fname = $arr["fname"]==null?"":$arr["fname"];
                $lname = $arr["lname"]==null?"":$arr["lname"];
                $sex = $arr["sex"]==null?"":$arr["sex"];
                $phone = $arr["phone"]==null?"":$arr["phone"];
                $email = $arr["email"]==null?"":$arr["email"];
                $sql = $sql = "insert into eui_user(fname,lname,sex,phone,email) values(‘$fname‘,‘$lname‘,‘$sex‘,‘$phone‘,‘$email‘)";
                $result = $medoo->query($sql);
                if($result){
                    echo json_encode(array(‘success‘=>true));
                }else{
                    echo json_encode(array(‘errorMsg‘=>‘操作过程出现错误!‘));
                }
            }else{
                $result = $medoo->insert("eui_user",$arr);
                if($result){
                    echo json_encode(array(‘success‘=>true));
                }else{
                    echo json_encode(array(‘errorMsg‘=>‘操作过程出现错误!‘));
                }
            }
        }
        

这节就完成了,这节代码。其中medoo.php附加了(看上一节)。

所需代码文件(index.php,medoo.php,jquery.edatagrid.js,userAction.php,userModel.php)bus_pubuser.js可以去掉;
