init: function (){}方法的写法原因

最近在做九宫格的抽奖，在看别人写的代码时看到这样的代码

 var lottery={        index:-1,            count:0,            .........        init:function(id){                   },        roll:function(){                  }    };

简单，就是对整个页面的初始化。

再详细一点说，就是这样的写法是最近几年开始流行的json写法，把所有的function，所有的变量等，都用

var o = {        x: func,         y: "",        z: obj       }

这样的写法来写。而调用直接用o.x ;o.z()即可

如

<script type="text/javascript">    var obj={        count:0,        timer:0,        init:function(str){            alert("init调用："+str);        },        exit:function(str){            alert("exit调用："+str);        }    };    function someThing(){        obj.timer += 1;        obj.init('init');        obj.exit('exit');        alert(obj.timer)    }    window.onload=function(){        someThing();    }</script>

之前项目的一段代码:

require([contextPath + '/js/assets/common.js'], function (common) {require(['jquery', 'bootstrap', 'easyuiUtil','jqueryForm','layer'], function ($, bootstrap,easyuiUtil,jqueryForm,layer) {Namespace('taskinfo.taskinfoList', {init: function () {//加载列数据easyui.util.initDatagrid('#datagrid', {url: contextPath + '/taskinfo/query',columns:[[     {field:'name',title:'任务名称',width:120},    {field:'cron',title:'执行周期',width:80},  {field:'taskBeanId',title:'任务执行类名',width:80},  {field:'status',title:'状态',width:80,formatter: function(value,row,index){if ('1'==value){return "启用";} else {return "禁用";}}  },  {field:'createTime',title:'创建时间',width:80},  {field:'remarks',title:'备注',width:120}]],  onDblClickRow: function (index,row) {taskinfo.taskinfoList.editPage()}});},addPage: function () {window.top.tempvalues = {};var addwindow = window.top.layer.open({type: 2,area: ['1000px', '90%'],skin: 'layui-layer-demo DB-style', //加上边框title: '<div class="portlet-title"><div class="caption"><i class="blue fa fa-database"></i>添加任务</div></div>',shadeClose: false,content: contextPath + '/taskinfo/add',});window.top.tempvalues.callback = function(){$("#datagrid").datagrid("reload");window.top.layer.close(addwindow);}},editPage: function () {window.top.tempvalues = {};var selected = $("#datagrid").datagrid("getSelected");if(selected!=null){var ewindow = window.top.layer.open({type: 2,area: ['1000px', '90%'],skin: 'layui-layer-demo DB-style', //加上边框title: '<div class="portlet-title"><div class="caption"><i class="blue fa fa-database"></i>添加任务</div></div>',shadeClose: false,content: contextPath + '/taskinfo/update/'+selected.id,});window.top.tempvalues.callback = function(){$("#datagrid").datagrid("reload");window.top.layer.close(ewindow);}}else{layer.msg('请选择一个任务！');}},changeStatus: function () {var selected = $("#datagrid").datagrid("getSelected");if(selected!=null){$.post(contextPath + '/taskinfo/changeStatus/'+selected.id,function (result) {if (result.code == 200) {$('#datagrid').datagrid('reload');}layer.msg(result.message);}, 'json');}else{layer.msg('请选择一个任务！');}},deleteTaskinfo: function () {var selected = $("#datagrid").datagrid("getSelected");if(selected!=null){$.messager.confirm('信息提示', '确定要删除吗？', function (sure) {if (!sure)return;$.post(contextPath + '/taskinfo/delete/'+selected.id,function (result) {if (result.code == 200) {top.showInfo('删除成功!');$('#datagrid').datagrid('reload');} else {top.showInfo('删除失败!');}}, 'json');});}else{layer.msg('请选择一个任务！');}}});$(function () {  $("div.table-scrollable").height($(document.body).height()-140);      $(window).resize(function() {        $("div.table-scrollable").height($(document.body).height()-140);      });      taskinfo.taskinfoList.init();});});});
