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。
1 //初始化函数 2 multiSelectColInit(); 3 //调用下拉多选点击事件以及对应传参 4 5 function multiSelectColInit() { 6 multiSelect = { 7 //ajaxmodelnames: [], //此jqgrid列头名称对应的id数组用于传给后台 8 contorlJqgridCol: function(names, modelnames, kehuSelectHides, ajaxHideIds) { 9 var self = $("input[data-multiselect]"), 10 selfHei = self.outerHeight(true), //点击input的高度 11 self_offset_top = self.offset().top, 12 self_left = self.offset().left, 13 selectHides = selectSames(modelnames, kehuSelectHides), 14 self_top = self_offset_top + selfHei, 15 multi_select = '<div class=multiSelect><ul><li class="ckAllLi"><input type="checkbox" checked="true" class="ckAllBox">全选</li>', 16 len = names.length, //总列数 17 hideLen = selectHides.length, //隐藏的列数 18 showLen = len - hideLen, //显示的列数 19 selfStr = '共有' + len + '列，显示' + showLen + '列，隐藏' + hideLen + '列', //17.5.4新增 20 //ajaxnames = [], //此jqgrid列头名称数组用于传给后台 21 ajaxmodelnames = selectHides; //此jqgrid列头名称对应的id数组用于传给后台 22 if (hideLen > 0) { 23 multi_select = '<div class=multiSelect><ul><li class="ckAllLi"><input type="checkbox" class="ckAllBox">全选</li>'; 24 } 25 for(i = 0; i < len; i++) { 26 if(selectHides.indexOf(modelnames[i]) > -1) { 27 multi_select += '<li class="multiLi"><input type="checkbox" value=' + modelnames[i] + ' class="multiCheckBox">' + names[i] + '</li>'; 28 } else { 29 multi_select += '<li class="multiLi"><input type="checkbox" checked="true" value=' + modelnames[i] + ' class="multiCheckBox">' + names[i] + '</li>'; 30 } 31 32 } 33 multi_select += '</ul></div>'; 34 $('body').append(multi_select); 35 $('.multiSelect').css({ 36 'top': self_top, 37 'left': self_left 38 }); 39 //新增初次加载input框内显示有多少列，多少列默认没有显示 40 self.val(selfStr); 41 self.attr('showcol', showLen); 42 //17-5-8 新增窗口大小改变事件重新定位多选框 43 $(window).resize(function () { 44 if ($('.multiSelect').length) { 45 var selfHei = self.outerHeight(true), //点击input的高度 46 self_offset_top = self.offset().top, 47 self_left = self.offset().left, 48 self_top = self_offset_top + selfHei; 49 $('.multiSelect').css({ 50 'top': self_top, 51 'left': self_left 52 }); 53 } 54 55 }); 56 $("input[data-multiselect]").click(function(e) { 57 stopPropagation(e); 58 if($('.multiSelect').length) { 59 $('.multiSelect').show(); 60 } 61 }) 62 $('.multiSelect').click(function(e) { 63 stopPropagation(e); 64 }) 65 $(document).on("click", function() { 66 if($('.multiSelect').length && $('.multiSelect').is(":visible")) { 67 $('.multiSelect').hide(function() { //回调是否保存数据 68 ajaxHideIds(ajaxmodelnames); 69 }); 70 } 71 }) 72 $(".multiCheckBox").click(function(e) { 73 stopPropagation(e); 74 var val = $(this).attr("value"), 75 showcol = parseInt(self.attr('showcol')), 76 newshowcol = 0; 77 if(!$(this).prop("checked")) { //如果当前选中 78 $("#gridlist").jqGrid('hideCol', val); 79 newshowcol = showcol - 1; 80 ajaxmodelnames.push(val); 81 } else { 82 $("#gridlist").jqGrid('showCol', val); 83 newshowcol = showcol + 1; 84 ajaxmodelnames.remove(val); 85 } 86 var newnoshowcol = len - newshowcol; 87 selfStr = '共有' + len + '列，显示' + newshowcol + '列，隐藏' + newnoshowcol + '列'; //17.5.4新增 88 self.val(selfStr); 89 self.attr('showcol', newshowcol); 90 }) 91 $('.multiLi,.ckAllLi').click(function (e) { 92 stopPropagation(e); 93 var ChildInput = $(this).find('input'); 94 ChildInput.trigger('click'); 95 }) 96 $(".ckAllBox").click(function (e) {//全选input的全选点击事件 97 stopPropagation(e); 98 if ($(this).prop("checked")) {//应该全部隐藏 99 $(".multiCheckBox").each(function (index, obj) {100 var _this = $(obj);101 if (!_this.prop("checked")) {102 _this.trigger("click");103 }104 })105 106 } else {107 $(".multiCheckBox").each(function (index, obj) {108 var _this = $(obj);109 if (_this.prop("checked")) {110 _this.trigger("click");111 }112 })113 }114 })115 116 },117 jqgridHiddenColInit: function(opt, modelnames, kehuSelectHides) { //opt为传入的jqgrid的option.model118 var objModel = opt,119 objModelLen = objModel.length;120 for(var k = 0; k < objModelLen; k++) {121 if(selectSames(modelnames, kehuSelectHides).indexOf(objModel[k].name) > -1) {122 objModel[k].hidden = true;123 }124 }125 return objModel;126 }127 }128 129 }130 131 function stopPropagation(e) {132 window.event ? window.event.cancelBubble = true : e.stopPropagation();133 }134 135 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136 //arr1是jqgrid自带的所有modelname的id集合137 //arr2是客户选择的需要隐藏的jqgrid的id集合138 //arr3是返回2个数组中重复的id集合139 var arr3 = [];140 for(var s in arr1) {141 for(var x in arr2) {142 if(x != 'remove') {143 if(arr2[x] == arr1[s]) {144 arr3.push(arr1[s]);145 }146 }147 }148 }149 return arr3;150 }151 152 Array.prototype.indexOf = function(val) {153 for(var i = 0; i < this.length; i++) {154 if(this[i] == val) return i;155 }156 return -1;157 };158 Array.prototype.remove = function(val) {159 var index = this.indexOf(val);160 if(index > -1) {161 this.splice(index, 1);162 }163 };
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。

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~~~
