项目使用 springmvc4.x  spring4.x  hibernate4.x easyui

为了便于开发，扩展了easyui 的 datagrid 功能，下面直接贴上扩展代码：

/**

* context 指定为 项目上下文* index 如果定义多组dataGrid，index指定为对应的参数：一组dataGrid包含（datagrid;toorbar;dialog;button）* templateUrl 指定为 此次访问操作对应的controller路径* crud 指定为  对应的toorbar包含什么操作；crud：增加修改删除; c：增加; u：修改; d：删除;*/
function DataGridEasyui(context, index, templateUrl, crud) {this.context = context;this.index = index;this.templateUrl = templateUrl;this.crud = crud;// 'c','r','u','d','all'this.saving =false; //处理中
};$.extend(DataGridEasyui.prototype, {/*** 初始化DataGridEasyui* crud按钮的响应操作  增加：add; 修改：edit; 删除:remove;*/init : function() {this.dataGrid = $("#dg-" + this.index);this.toolBar = $("#toolbar-" + this.index);this.dlg = $("#dlg-" + this.index);this.dlgBtn = $("#dlg-buttons-" + this.index);var fns = [ this.proxy(this.add, this,this.toolBar.find(".add")), this.proxy(this.edit, this,this.toolBar.find(".edit")),this.proxy(this.remove, this,this.toolBar.find(".remove")) ];//toolBar 响应函数if (this.crud == 'crud') {this.toolBar.find(".add").bind('click', fns[0]);this.toolBar.find(".edit").bind('click', fns[1]);this.toolBar.find(".remove").bind('click', fns[2]);} else if (this.crud == 'c') {this.toolBar.find(".add").bind('click', fns[0]);} else if (this.crud == 'u') {this.toolBar.find(".edit").bind('click', fns[1]);} else if (this.crud == 'd') {this.toolBar.find(".remove").bind('click', fns[2]);}//dlg-buttons 响应函数 if (this.crud == 'crud' || this.crud == 'c' || this.crud == 'u') {this.dlgBtn.find('.save').bind('click', this.proxy(this.save, this,this.dlgBtn.find('.save')));this.dlgBtn.find('.cancel').bind('click',this.proxy(this.cancel, this,this.dlgBtn.find('.cancel')));}},/*** 改变函数作用域* * @param fn* @param scope* @returns*/proxy : function(fn, scope,btn) {return function (){if(btn.is("[class*='disabled']")){  //禁用了不需要响应事件return ;}return fn.call(scope,arguments[0],btn);};},/*** 初始化dialog里面的form表单*/formInit : function() {},/*** toorbar的增加按钮*/add : function() {$('#dlg-' + this.index).dialog('open').dialog('setTitle', '新增');this.resetForm(this.dlg.find("form:eq(0)"));this.formInit.call(this);},/*** toorbar的修改按钮*/edit : function() {var rows = this.dataGrid.datagrid('getSelections');if (!rows || rows.length == 0) {$.messager.alert('提示', '请选择记录！');} else {if (rows.length == 1) {this.dlg.dialog('open').dialog('setTitle', '修改');this.dlg.find("form").form('clear').form('load', rows[0]);this.formLoadData(rows[0]);} else {$.messager.alert('提示', '请选择单行记录！');}}},/*** toorbar的删除按钮*/remove : function() {var this_ = this;var rows = $('#dg-' + this.index).datagrid('getSelections');if (!rows || rows.length > 0) {$.messager.confirm('确认', '你确定要删除所选的记录吗?', function(r) {if (r) {$.post(this_.getController("logicDelete"), {pids : $.map(rows, function(row) {return row.pid;}).join("::")}, function(result) {if (result.success) {this_.reload.call(this_);$.messager.show({ // show// tipstitle : '提示',msg : result.msg});} else {$.messager.alert('错误', result.msg);}}, 'json');}});} else {$.messager.alert('提示', '请选择记录！');}},/*** 重置dialog里面的form表单*/resetForm:function(form){var form =  $(form);form[0].reset();form.find("[type=hidden]").val("");},/*** form表单加载数据*/formLoadData:function (data){//处理隐藏域this.dlg.find("form:eq(0) input[type!=radio][type!=checkbox][name*='.']").each(function(){var name =  $(this)[0].name;var value = data[name];if(value){$(this).val(value);return ;}if(name.indexOf(".")!=-1){var names = name.split(".");value =data ;for(var i=0,l = names.length;i<l;i++){value = value[names[i]];if(!value){return ;}}$(this).val(value);}});//处理单选多选this.dlg.find("form:eq(0) input[type=radio]").each(function(){var name =  $(this)[0].name;var value  =data[name] ;if(value){if($(this).val() == value){$(this)[0].checked="checked";}return ;}if(name.indexOf(".")!=-1){var names = name.split(".");value = data ;for(var i=0,l = names.length;i<l;i++){try{value = value[names[i]];}catch(e){return ;}}}else{value = data[name];}if($(this).val() == value){$(this)[0].checked="checked";}});//处理单选多选this.dlg.find("form:eq(0) input[type=checkbox]").each(function(){var name =  $(this)[0].name;var value  =data[name] ;var this_ = this ;if(value){$(value).each(function (index ,item ){if($(this_).val() == item){$(this_)[0].checked="checked";}});return ;}if(name.indexOf(".")!=-1){var names = name.split(".");value = data ;for(var i=0,l = names.length - 1;i<l;i++){try{value = value[names[i]];}catch(e){return ;}}if($.isArray(value)){for(var i=0,l =value.length ;i <l;i++ ){if(value[i][names[names.length-1]]==$(this).val()){$(this)[0].checked="checked";return ;}}}}else{value = data[name];}if($(this).val() == value){$(this)[0].checked="checked";}});this.dlg.find("form:eq(0) select").each(function (){var name =  $(this)[0].name;var value  =data[name] ;if(value){$(this).val(value);return ;}if(name.indexOf(".")!=-1){var names = name.split(".");value = data ;for(var i=0,l = names.length;i<l;i++){value = value[names[i]];if(!value){return ;}}}else{value = data[name];}$(this).val(value);});},reload:function (){this.dataGrid.datagrid('reload'); // reload
