JQuery对象函数

1、JQuery对象函数写法格式

简单示例：

main代表对象名，main.roleName = (function () { return $('#RoleName').val();})();表示为对象的roleName属性赋值。

 $(document).ready(function () {
 MainManager.init();
 });

 var MainManager = window.MainManager = {};

 (function (main) {
 main.init = function () {
 this.roleName();
 }

 main.roleName = (function () {
 return $('#RoleName').val();
 })();

 })(MainManager);

实例：

注意下面下拉列表写法格式，有多种情况可以借鉴，

 $(document).ready(function () {
     MainManager.init();
 });

 var MainManager = window.MainManager = {};

 (function (main) {
     main.init = function () {
         this.bindBtnSearch();
         this.bindBtnClear();
         this.initSearchCombo();
         this.initGirdMain();
     }

     main.roleName = (function () {
         return $('#RoleName').val();
     })();

     main.commType = (function () {
         return $('#frmSearch #CommType').val();
     })();

     main.initSearchCombo = function () {
         var frmSearch = $('#frmSearch');
         frmSearch.find('#Fstatus').first().combobox({
             valueField: 'CodeNO',
             textField: 'CodeName',
             panelHeight: 'auto',
             data: [
              { CodeNO: '', CodeName: '--全部--' },
              { CodeNO: 3, CodeName: '已保存' },
              { CodeNO: 0, CodeName: '待审核' },
              { CodeNO: 1, CodeName: '已审核' },
              { CodeNO: 2, CodeName: '已关闭' }
             ]
         });
