本文给出jqgrid和laravel的Eloquent 数据交互接口。

1. json访问格式

通过http://localhost:8000/json去获取数据,在请求的时候,还会加上一些默认参数。

http://localhost:8000/json?_search=false&nd=1422412397217&rows=10&page=1&sidx=id&sord=desc

这个是真正在访问的时候请求数据参数。

function pageInit() {
        var lastsel;
        jQuery("#list4").jqGrid({
            width:"800",
            url: ‘http://localhost:8000/json‘,
            datatype: "json",
            colNames: [‘Inv No‘, ‘game_name‘, ‘game_id‘, ‘game_server‘, ‘game_auth‘, ‘created_at‘, ‘updated_at‘],
            colModel: [
                {name: ‘id‘, index: ‘id‘, width: 55},
                {name: ‘game_name‘, index: ‘game_name‘, width: 90, editable: true},
                {name: ‘game_id‘, index: ‘game_id‘, width: 100, editable: true},
                {name: ‘game_server‘, index: ‘game_server‘, width: 80, align: "right", editable: true},
                {name: ‘game_auth‘, index: ‘game_auth‘, width: 80, align: "right", editable: true},
                {name: ‘created_at‘, index: ‘created_at‘, width: 200, align: "right", editable: true},
                {name: ‘updated_at‘, index: ‘updated_at‘, width: 150, sortable: false, editable: true}
            ],
            rowNum: 10,
            rowList: [10, 20, 30],
            pager: ‘#pager2‘,
            sortname: ‘id‘,
            viewrecords: true,
            sortorder: "desc",
            onSelectRow: function (id) {
                if (id && id !== lastsel) {
//                    alert("hello");
                    jQuery(‘#list4‘).jqGrid(‘restoreRow‘, lastsel);
                    jQuery(‘#list4‘).jqGrid(‘editRow‘, id, true);
                    lastsel = id;
                }
            },
            editurl: "http://www.trirand.com/blog/jqgrid/server.php",
            caption: "Using events example"
        });
       jQuery("#list4").jqGrid(‘navGrid‘, "#pager2", {edit: false, add: false, del: false});
    }
</script>

服务器端代码:

public function json()
    {
        $all = ModelAccount::all();
//        $total = $all->count() / Input::get("rows");
        $total = ceil($all->count()/Input::get("rows"));//*Input::get("rows") / 10;
        return ‘{"page":"‘.Input::get("page").‘","total":"‘.$total.‘","records":"‘.$all->count().‘","rows":‘.$all.‘}‘;
        //return $all;
    }

这是一种最原始的方式。出来的界面如下图

1.1 排序

感觉jqgrid是不会自己排序的,每次点击排序的话,会发送请求给服务器端,服务器端会再执行一次数据库查询。这点感觉效率不是很高。

通过点击Inv No上下排序的话,会再次发送一个请求。

http://localhost:8000/json?_search=false&nd=1422416288639&rows=10&page=1&sidx=id&sord=asc

如果点击game_name的话,请求又变成了

http://localhost:8000/json?_search=false&nd=1422416317800&rows=10&page=1&sidx=game_name&sord=asc

根据分析,sord是决定排序是倒序还是顺序。sidx是决定根据哪个字段来进行排序。

那么服务器端需要根据该请求做相应的判断。

public function json()
    {
        $all = ModelAccount::orderBy(Input::get("sidx"), Input::get("sort"))->get();
        $total = ceil($all->count()/Input::get("rows"));//*Input::get("rows") / 10;
        return ‘{"page":"‘.Input::get("page").‘","total":"‘.$total.‘","records":"‘.$all->count().‘","rows":‘.$all.‘}‘;
        //return $all;
    }

1.2 优化查询效率

我们看到每次查询的时候时候都会把数据库的表全部遍历一遍,从效率优化的角度,应该每次只返回相应数量的数据就可以了。

按照上例,每次只需要取10条数据就可以了。

服务器端相应代码修改如下:

public function json()
    {
        $value = ModelAccount::orderBy(Input::get("sidx"), Input::get("sort"))->take(Input::get("rows"))->get();
        $all = ModelAccount::all()->count();
        $total = ceil($all/Input::get("rows"));//*Input::get("rows") / 10;
        return ‘{"page":"‘.Input::get("page").‘","total":"‘.$total.‘","records":"‘.$all.‘","rows":‘.$value.‘}‘;
        //return $all;
    }

通过chrome分析可以得到,确实每次只拉出来10条数据。

1.3 从哪里开始?

解决了数量问题,那么需要解决数据从哪里开始的问题了。

我们来看,如果用户切换到第二个页面的话,那么相应的请求就变成

http://localhost:8000/json?_search=false&nd=1422417279445&rows=10&page=2&sidx=id&sord=desc

服务器端的代码相应需要修改

public function json()
    {
        $offset = (Input::get("page") - 1) * Input::get("rows");
        $value = ModelAccount::orderBy(Input::get("sidx"), Input::get("sort"))->take(Input::get("rows"))->offset($offset)->get();//->paginate(Input::get("rows"))->getFrom($offset);//take(20)->offset(10)->get();
        $all = ModelAccount::all()->count();
        $total = ceil($all/Input::get("rows"));//*Input::get("rows") / 10;
        return ‘{"page":"‘.Input::get("page").‘","total":"‘.$total.‘","records":"‘.$all.‘","rows":‘.$value.‘}‘;
    }

1.4 每次查询的数据量

每次查询的数据量是根据界面数据给出来的,在代码中可以通过rowList来指定几种。

1.5 条件查询

通过点击搜索,可以弹出搜索对话框。

技术分享

点击Find之后,会向服务器发送请求。

http://localhost:8000/json?_search=true&nd=1422422941250&rows=30&page=1&sidx=id&sord=desc&searchField=id&searchString=868&searchOper=eq&filters=

主要是4个参数

1._search=true

2.searchField=id

3.searchString=868

4.searchOper=eq

那么我们相应的服务器端代码修改

public function json()
    {
        $searchField=‘‘;
        $searchOper=‘‘;
        $searchString=‘‘;
        $value=‘‘;
        $all=‘‘;
        $offset = (Input::get("page") - 1) * Input::get("rows");
        if(!strcmp(Input::get("_search"), "true")){
            $searchField=Input::get("searchField");
            $searchOper=Input::get("searchOper");
            if(!strcmp($searchOper, "eq")) {//equal
                $searchOper="=";
            } else if(!strcmp($searchOper,"ne")) { //not equal
                $searchOper="";
            } else if(!strcmp($searchOper,"bw")) { //begin with

            } else if(!strcmp($searchOper,"bn")) { //not begin with
            } else if(!strcmp($searchOper,"ew")) { //ends with
            } else if(!strcmp($searchOper,"en")) { //not ends with
            } else if(!strcmp($searchOper,"cn")) { //contains
            } else if(!strcmp($searchOper,"nc")) { //not contains
            } else if(!strcmp($searchOper,"nu")) { //is null
            } else if(!strcmp($searchOper,"nn")) { //not is null
            } else if(!strcmp($searchOper,"in")) { //is null
            } else if(!strcmp($searchOper,"ni")) { //is null
            }
            $searchString=Input::get("searchString");
            $value = ModelAccount::where($searchField, $searchOper, $searchString)->orderBy(Input::get("sidx"), Input::get("sort"))->take(Input::get("rows"))->offset($offset)->get();//->paginate(Input::get("rows"))->getFrom($offset);//take(20)->offset(10)->get();
            $all = ModelAccount::where($searchField, $searchOper, $searchString)->count();
        } else {
            $value = ModelAccount::orderBy(Input::get("sidx"), Input::get("sort"))->take(Input::get("rows"))->offset($offset)->get();//->paginate(Input::get("rows"))->getFrom($offset);//take(20)->offset(10)->get();
            $all = ModelAccount::all()->count();
        }
        $total = ceil($all/Input::get("rows"));//*Input::get("rows") / 10;
        return ‘{"page":"‘.Input::get("page").‘","total":"‘.$total.‘","records":"‘.$all.‘","rows":‘.$value.‘}‘;
    }

如何去除多余的搜索条件?

修改对应语言文件的search段中odata.

odata: [{ oper:‘eq‘, text:‘等于\u3000\u3000‘},{ oper:‘ne‘, text:‘不等\u3000\u3000‘},{ oper:‘lt‘, text:‘小于\u3000\u3000‘},{ oper:‘le‘, text:‘小于等于‘},{ oper:‘gt‘, text:‘大于\u3000\u3000‘},{ oper:‘ge‘, text:‘大于等于‘},{ oper:‘bw‘, text:‘开始于‘},{ oper:‘bn‘, text:‘不开始于‘},{ oper:‘in‘, text:‘属于\u3000\u3000‘},{ oper:‘ni‘, text:‘不属于‘},{ oper:‘ew‘, text:‘结束于‘},{ oper:‘en‘, text:‘不结束于‘},{ oper:‘cn‘, text:‘包含\u3000\u3000‘},{ oper:‘nc‘, text:‘不包含‘},{ oper:‘nu‘, text:‘不存在‘},{ oper:‘nn‘, text:‘存在‘}],

2.数据修改

2.1 通过事件实现

双击某一行之后,可以进行修改

2.2 导航条编辑

通过添加

jQuery("#list4").jqGrid(‘inlineNav‘,"#pager2");

会使用内部编辑。

技术分享

2.3 数据提交

编辑了数据,那么我们怎么提交到数据库呢?

首先需要我们在laravel里面添加一条post路由。

Route::post(‘edit_jqgrid‘, array(‘as‘ => ‘edit_jqgrid‘, ‘uses‘ => ‘ControllerAccount@edit_jqgrid‘));

在jqgrid的javascript里面添加:

在编辑保存的时候,通过chrome分析确实是发送了edit_jqgrid的post请求。

3.界面本地化

现有模块的本地化,可以使用以下语句

<script src="js/i18n/grid.locale-cn.js" type="text/javascript"></script>

其他文字的本地化,在这里面需要注意一点,尽量使用统一的本地化模式,因为本来laravel里面会有一个本地化的模块。

3.1 laravel 本地化

在app/lang里面增加一个cn目录,新建一个message.php文件,内容如下:

<?php
/**
 * Created by PhpStorm.
 * User: Administrator
 * Date: 2015/1/30
 * Time: 11:11
 */
return array(
    ‘welcome‘ => ‘Welcome to our application‘,
    ‘id‘ => ‘编号‘,
    ‘game_name‘ => ‘玩家名字‘,
    ‘game_id‘ => ‘玩家编号‘,
    ‘game_server‘ => ‘游戏区‘,
    ‘game_auth‘ => ‘权限‘,
    ‘created_at‘ => ‘创建时间‘,
    ‘updated_at‘ => ‘更新时间‘
);

修改config/app.php文件,将locale设置为cn.

修改jqgrid代码:

datatype: "json",
            colNames: [‘{{Lang::get(‘message.id‘)}}‘,
                        ‘{{Lang::get(‘message.game_name‘)}}‘,
                        ‘{{Lang::get(‘message.game_id‘)}}‘,
                        ‘{{Lang::get(‘message.game_server‘)}}‘,
                        ‘{{Lang::get(‘message.game_auth‘)}}‘,
                        ‘{{Lang::get(‘message.created_at‘)}}‘,
                        ‘{{Lang::get(‘message.updated_at‘)}}‘],
            colModel: [

 

修改完成之后显示界面如下:

4.界面自定义

4.1 字体

这个字体个人觉得比较难看,我想改成微软雅黑字体,并且字体大小增加一倍。

<STYLE type="text/css">
    /* Jqgrid */
    .ui-jqgrid .ui-jqgrid-view {font-size:14px;} /*修改grid标题的字体大小*/
    .ui-jqgrid-sortable {font-size:14px;} /*修改列名的字体大小*/
    .ui-widget-content .jqgrow .ui-row-ltr .ui-jqgrid-view {font-size:14px;} /*修改表格内容字体,不起作用*/
</style>

这个时候只是修改表格里面的字体大小,其他的大小还没有修改。

技术分享

添加:

<STYLE type="text/css">
    /* Jqgrid */
    .ui-jqgrid .ui-jqgrid-view {font-size:14px;} /*修改grid标题的字体大小*/
    .ui-jqgrid .ui-jqgrid-pager {font-size:14px;} /*修改grid标题的字体大小*/
    .ui-jqgrid-sortable {font-size:14px;} /*修改列名的字体大小*/
    .ui-widget-content .jqgrow .ui-row-ltr .ui-jqgrid-view {font-size:14px;} /*修改表格内容字体,不起作用*/
</style>

技术分享

添加:

<STYLE type="text/css">
    /* Jqgrid */
    .ui-jqgrid .ui-jqgrid-view {font-size:14px;} /*修改grid标题的字体大小*/
    .ui-jqgrid .ui-jqgrid-pager {font-size:14px;} /*修改grid标题的字体大小*/
    .ui-jqgrid .ui-jqgrid-titlebar {font-size: 16px;}
    .ui-jqgrid-sortable {font-size:14px;} /*修改列名的字体大小*/
    .ui-widget-content .jqgrow .ui-row-ltr .ui-jqgrid-view {font-size:14px;} /*修改表格内容字体,不起作用*/
</style>

最后的css代码为:

<STYLE type="text/css">
    /* Jqgrid */
    .ui-jqgrid .ui-jqgrid-view {font-size:14px;} /*修改grid标题的字体大小*/
    .ui-jqgrid .ui-jqgrid-pager {font-size:14px;} /*修改grid标题的字体大小*/
    .ui-jqgrid .ui-jqgrid-titlebar {font-size: 16px;}
    .ui-jqdialog-title {font-size: 14px;}
    .ui-jqgrid-sortable {font-size:14px;} /*修改列名的字体大小*/
    .ui-widget-content .jqgrow .ui-row-ltr .ui-jqgrid-view {font-size:14px;} /*修改表格内容字体,不起作用*/
    .CaptionTD {font-size:14px}
    .fm-button {font-size:14px}
    .ui-jqdialog {font-size: 14px}
</style>

4.2 搜索

4.2.1组合搜索

在navGrid的搜索参数里面增加

{//SEARCH
            closeOnEscape: true,
            multipleSearch:true,
            //multipleGroup:true

        }

http://localhost:8000/json?_search=true&nd=1422596038311&rows=10&page=1&sidx=id&sord=desc&filters=%7B%22groupOp%22%3A%22AND%22%2C%22rules%22%3A%5B%7B%22field%22%3A%22game_name%22%2C%22op%22%3A%22eq%22%2C%22data%22%3A%22901%22%7D%5D%7D&searchField=&searchString=&searchOper=

翻译成正常的url地址为:

http://localhost:8000/json?_search=true&nd=1422596038311&rows=10&page=1&sidx=id&sord=desc&filters={"groupOp":"AND","rules":[{"field":"game_name","op":"eq","data":"901"}]}&searchField=&searchString=&searchOper=

根据分析组合查询分为大致的4种情况:

1.同时满足一个条件

http://localhost:8000/json?_search=true&nd=1422596038311&rows=10&page=1&sidx=id&sord=desc&filters={"groupOp":"AND","rules":[{"field":"game_name","op":"eq","data":"901"}]}&searchField=&searchString=&searchOper=

2.同时满足n个条件

4.2.2 分组查询

具体还没有分析

4.2.3 Toolbar查询

jqgrid添加以下代码:

jQuery("#list4").jqGrid(‘filterToolbar‘,{searchOperators : true});

界面效果为:

技术分享

这个时候的查询请求为:

http://localhost:8000/json?_search=true&nd=1422599565652&rows=10&page=1&sidx=id&sord=desc&game_auth=7

这种情况会比较复杂,因为game_auth字段是数据库中的字段,可能无法做到一定的通用性。

如果同时查询两个字段的话,请求为:

http://localhost:8000/json?_search=true&nd=1422599807064&rows=10&page=1&sidx=id&sord=desc&game_auth=7&game_server=37
