Jquery EasyUI的添加，修改，删除，查询等基本操作介绍

初识Jquery EasyUI看了一些博主用其开发出来的项目，页面很炫，感觉功能挺强大，效果也挺不错，最近一直想系统学习一套前台控件，于是在网上找了一些参考示例。写了一些基本的增删改查功能，算是对该控件的基本入门。后续有时间继续深入学习。

在学习jquery easyui前应该先到官网下载最新版本http://www.jeasyui.com/download/index.php

先看一下运行后的页面

1、列表展示

2、新增页面

3、修改页面

把jquery easyui下载好之后，一般引用下页几个文件

<link href="http://www.cnblogs.com/Resources/easyui/css/default.css" rel="stylesheet" type="text/css" />
    <link href="http://www.cnblogs.com/Resources/easyui/js/themes/default/easyui.css" rel="stylesheet"
        type="text/css" />
//页面图标样式
    <link href="http://www.cnblogs.com/Resources/easyui/js/themes/icon.css" rel="stylesheet" type="text/css" />
    <script src="http://www.cnblogs.com/Resources/easyui/js/jquery-1.7.2.min.js" type="text/javascript"></script>
//jquery easyui主要的js
    <script src="http://www.cnblogs.com/Resources/easyui/js/jquery.easyui.min.js" type="text/javascript"></script>

首先是列表展示数据

<table id="dg" title="My Users" class="easyui-datagrid" style="width: 700px; height: 250px"
        url="http://www.cnblogs.com/GetJson/CreateJson.aspx" toolbar="#toolbar" pagination="true" rownumbers="true"
        fitcolumns="true" singleselect="true">
        <thead>
            <tr>
                <th field="AccountCode" width="50">
                    编号
                </th>
                <th field="AccountName" width="50">
                    卡名
                </th>
                <th field="AccountPwd" width="50">
                    密码
                </th>
                <th field="CreateTime" width="50">
                    创建时间
                </th>
                <th field="CreateName" width="50">
                    创建人
                </th>
            </tr>
        </thead>
    </table>

jquery easyui是用datagrid对数据进行展示的，所以class要选择easyui-datagrid；url是本列表的一个json格式的数据来源toobar后面跟着的"#toobar"是列表的一个工具栏，本示例在列表上显示的是添加，修改，删除功能按钮对数据进行操作。pagination是否显示分页，rownumbers显示行数，分页时向后台传去两个参数，一个就是当前页数另一个就是每页显示行数；fitcolumns：自适应列宽；singleselected:单选。
工具条代码

<div id="toolbar">
        <a href="javascript:void(0)" class="easyui-linkbutton" iconcls="icon-add" onclick="newuser()"
            plain="true">添加</a> <a href="javascript:void(0)" class="easyui-linkbutton" iconcls="icon-edit"
                onclick="edituser()" plain="true">修改</a> <a href="javascript:void(0)" class="easyui-linkbutton"
                    iconcls="icon-remove" plain="true">删除</a>
    </div>

数据源格式

数据源添加弹出框

<div id="dlg" class="easyui-dialog" style="width: 400px; height: 280px; padding: 10px 20px;"
       closed="true" buttons="#dlg-buttons"> 
       <div class="ftitle"> 
           信息编辑 
       </div> 
       <form id="fm" method="post"> 
       <div class="fitem"> 
           <label> 
               编号 
           </label> 
           <input name="AccountCode" class="easyui-validatebox" required="true" /> 
       </div> 
       <div class="fitem"> 
           <label> 
               卡号</label> 
           <input name="AccountName" class="easyui-validatebox" required="true" /> 
       </div> 
       <div class="fitem"> 
           <label> 
               密码</label> 
           <input name="AccountPwd" class="easyui-validatebox" required="true" /> 
       </div> 
       <div class="fitem"> 
           <label> 
               创建时间</label> 
           <input name="CreateTime" class="easyui-datebox" required="true" /> 
       </div> 
       <div class="fitem"> 
           <label> 
               创建人</label> 
           <input name="CreateName" class="easyui-vlidatebox" /> 
       </div> 
       <input type="hidden" name="action" id="hidtype" /> 
       <input type="hidden" name="ID" id="Nameid" /> 
       </form> 
   </div> 
?<div id="dlg-buttons"> 
        <a href="javascript:void(0)" class="easyui-linkbutton" onclick="saveuser()" iconcls="icon-save">保存</a> 
        <a href="javascript:void(0)" class="easyui-linkbutton" onclick="javascript:$('#dlg').dialog('close')"
            iconcls="icon-cancel">取消</a> 
    </div>

注：class为弹出框类型；closed:当前显示状态为隐藏；buttons:弹出框的功能按钮；

对弹出的添加页面添加样式

?<style type="text/css"> 
        #fm 
        { 
            margin: 0; 
            padding: 10px 30px; 
        } 
        .ftitle 
        { 
            font-size: 14px; 
            font-weight: bold; 
            padding: 5px 0; 
            margin-bottom: 10px; 
            border-bottom: 1px solid #ccc; 
        } 
        .fitem 
        { 
            margin-bottom: 5px; 
        } 
        .fitem label 
        { 
            display: inline-block; 
            width: 80px; 
        } 
    </style>

 js实现对数据的添加修改删除

    <script type="text/javascript">
        var url;
        var type;
        function newuser() {
            $("#dlg").dialog("open").dialog('setTitle', 'New User'); ;
            $("#fm").form("clear");
            url = "UserManage.aspx";
            document.getElementById("hidtype").value="submit";
        }
        function edituser() {
            var row = $("#dg").datagrid("getSelected");
            if (row) {
                $("#dlg").dialog("open").dialog('setTitle', 'Edit User');
                $("#fm").form("load", row);
                url = "UserManage.aspx?id=" + row.ID;
            }
        }
        function saveuser() {
            $("#fm").form("submit", {
                url: url,
                onsubmit: function () {
                    return $(this).form("validate");
                },
                success: function (result) {
                    if (result == "1") {
                        $.messager.alert("提示信息", "操作成功");
                        $("#dlg").dialog("close");
                        $("#dg").datagrid("load");
                    }
                    else {
                        $.messager.alert("提示信息", "操作失败");
                    }
                }
            });
        }
        function destroyUser() {
            var row = $('#dg').datagrid('getSelected');
            if (row) {
                $.messager.confirm('Confirm', 'Are you sure you want to destroy this user?', function (r) {
                    if (r) {
                        $.post('destroy_user.php', { id: row.id }, function (result) {
                            if (result.success) {
                                $('#dg').datagrid('reload');    // reload the user data  
                            } else {
                                $.messager.show({   // show error message  
                                    title: 'Error',
                                    msg: result.errorMsg
                                });
                            }
                        }, 'json');
                    }
                });
            }
        }  
    </script>
