前端基于JQgrid实现自定义列头展示

先上效果图  

因为公司项目的需要，并且公司只有我这一个能写js的前端，这个自定义展示jqgrid列选项的需求依然是交由我写，辣么就分享一下我的工作成果。

 //初始化函数
 multiSelectColInit();
 //调用下拉多选点击事件以及对应传参

 function multiSelectColInit() {
     multiSelect = {
         //ajaxmodelnames: [], //此jqgrid列头名称对应的id数组用于传给后台
         contorlJqgridCol: function(names, modelnames, kehuSelectHides, ajaxHideIds) {
             var self = $("input[data-multiselect]"),
                 selfHei = self.outerHeight(true), //点击input的高度
                 self_offset_top = self.offset().top,
                 self_left = self.offset().left,
                 selectHides = selectSames(modelnames, kehuSelectHides),
                 self_top = self_offset_top + selfHei,
                 multi_select = '<div class=multiSelect><ul><li class="ckAllLi"><input type="checkbox" checked="true" class="ckAllBox">全选</li>',
                 len = names.length, //总列数
                 hideLen = selectHides.length, //隐藏的列数
                 showLen = len - hideLen, //显示的列数
                 selfStr = '共有' + len + '列，显示' + showLen + '列，隐藏' + hideLen + '列', //17.5.4新增
                 //ajaxnames = [], //此jqgrid列头名称数组用于传给后台
                 ajaxmodelnames = selectHides; //此jqgrid列头名称对应的id数组用于传给后台
             if (hideLen > 0) {
                 multi_select = '<div class=multiSelect><ul><li class="ckAllLi"><input type="checkbox" class="ckAllBox">全选</li>';
             }
             for(i = 0; i < len; i++) {

                 }

             }

             $('body').append(multi_select);

         },
         jqgridHiddenColInit: function(opt, modelnames, kehuSelectHides) { //opt为传入的jqgrid的option.model
             var objModel = opt,
                 objModelLen = objModel.length;

                 if(selectSames(modelnames, kehuSelectHides).indexOf(objModel[k].name) > -1) {
                     objModel[k].hidden = true;

         }
     }

 }

 function stopPropagation(e) {
     window.event ? window.event.cancelBubble = true : e.stopPropagation();
 }

 function selectSames(arr1, arr2) { //选择前面2个数组中重复的赋值给第三个参数数组
     //arr1是jqgrid自带的所有modelname的id集合
     //arr2是客户选择的需要隐藏的jqgrid的id集合
     //arr3是返回2个数组中重复的id集合
     var arr3 = [];
     for(var s in arr1) {
         for(var x in arr2) {
             if(x != 'remove') {
                 if(arr2[x] == arr1[s]) {
                     arr3.push(arr1[s]);
                 }
             }
         }
     }
     return arr3;
 }

 Array.prototype.indexOf = function(val) {
     for(var i = 0; i < this.length; i++) {
         if(this[i] == val) return i;
     }
     return -1;
 };
 Array.prototype.remove = function(val) {
     var index = this.indexOf(val);
     if(index > -1) {
         this.splice(index, 1);
     }
 };

上面的是我封装好的函数代码，现在看一下html页面需要给予什么参数以及在哪里调用。

         </script>

 </body>

 </html>

需要注意的几个点：

• 1.参数选项需要看清楚，html和js里都有注释说明
• 2.jqgrid的版本4.6.0
• 3.jquery的版本1.11.0

这个功能的注意点主要是参数的传输以及何处调用，注意点搞清了，这个功能有需求的小伙伴们拿去用吧~~~
