详解velocity模板使javaWeb的html+js实现模块化

<!-- 展示分类与搜索标签组件使用说明：   1.新增时父页面调用方法：页面加载时调用 goodsClassifyAndSearchTag.getFirstLevelClassify();/** 初始化一级展示分类 **/   2.编辑时父页面调用方法：页面加载时调用 goodsClassifyAndSearchTag.getClassifyAndSearchTag(String classifys);     ShowClassifyList类型json串，可参考 /js/standard_v2/group/group_edit.js 该方法 groupGoodsObj.getEditClassify();   3.返回页面选中的展示分类和搜索标签，调用 goodsClassifyAndSearchTag.returnSelectedClassifyAndTag();   注意事项：可能会出现js冲突问题，父页面的js最好在文件顶部加载 --> <!--展示分类--> <div class="row form-horizontal">   <div class="col-md-12">     <div class="form-group">       <label class="col-md-1 control-label pr0">展示分类</label>       <div class="col-md-1">         <select class="form-control" id="first_classify" onchange="goodsClassifyAndSearchTag.getSecondClassify(this)">           <option value="0">请选择</option>         </select>       </div>       <div class="col-md-1">         <select class="form-control" id="second_classify" onchange="goodsClassifyAndSearchTag.getThirdClassify(this)">           <option value="0">请选择</option>         </select>       </div>       <div class="col-md-1">         <select class="form-control" id="third_classify" onchange="goodsClassifyAndSearchTag.getSearchTag(this)">           <option value="0">请选择</option>         </select>       </div>     </div>   </div> </div> <!--搜索标签--> <div class="row mb15">   <div class="col-md-12">     <h2><small>搜索标签：</small></h2>   </div> </div> <div class="row form-horizontal" id="classify_template">   <div class="col-md-12" name="tag_original">     <div name="selectTagDom" id="selectTagDom"></div>     <div name="commonTagDom" id="commonTagDom"></div>   </div> </div> <!-- 展示分类模板 --> <script id="classifyTemplate" type="text/x-jsrender">   <option value="{{:id}}">{{:classilyName}}</option> </script> <!-- 普通标签模板 --> <script id="commonTagTemplate" type="text/x-jsrender">   <div class="form-group">     <label class="col-md-1 control-label pr0">{{:optionName}}</label>     <div class="col-md-9">       {{for optionValues}}         <label class="checkbox-inline">           {{if checked==true}}             <input type="checkbox" checked name='{{: #data.optionId}}' optionid='{{: #data.optionId}}' valueid='{{: #data.id}}'>           {{else}}             <input type="checkbox" name='{{: #data.optionId}}' optionid='{{: #data.optionId}}' valueid='{{: #data.id}}'/>           {{/if}}           <span>{{: #data.value}}</span>         </label>       {{/for}}     </div>   </div> </script> <!-- 级联标签模板 --> <script id="selectTagTemplate" type="text/x-jsrender">   <div class="form-group" id='label_{{:optionId}}' valueid='{{:valueId}}'>     <label class="col-md-1 control-label pr0">{{:optionName}}</label>     <div class="col-md-9">       {{for optionValues}}         <label class="checkbox-inline">           {{if checked==true}}             <input type="checkbox" checked name='{{: #data.optionId}}' optionid='{{: #data.optionId}}' valueid='{{: #data.id}}' onclick='goodsClassifyAndSearchTag.getChildSelectOption({{: #data.optionId}}, {{: #data.id}}, this)'>           {{else}}             <input type="checkbox" name='{{: #data.optionId}}' optionid='{{: #data.optionId}}' valueid='{{: #data.id}}' onclick='goodsClassifyAndSearchTag.getChildSelectOption({{: #data.optionId}}, {{: #data.id}}, this)'/>           {{/if}}           <span>{{: #data.value}}</span>         </label>       {{/for}}     </div>   </div> </script> <!-- 级联子标签模板 --> <script id="childOptionTemplate" type="text/x-jsrender">   <div class="form-group" name='label_{{:optionId}}' valueId='{{:valueId}}'>     <lable class="col-md-1 control-label pr0">{{:optionName}}</lable>     <div class="col-md-9">       {{for optionValues}}         <label class="checkbox-inline">           <input type="checkbox" name='{{:#parent.parent.data.optionId}}' optionid='{{: #data.optionId}}' valueid='{{: #data.id}}' onclick='goodsClassifyAndSearchTag.getChildSelectOption({{: #data.optionId}}, {{: #data.id}}, this)'/>           <span>{{: #data.value}}</span>         </label>       {{/for}}     </div>   </div> </script> <!--展示分类和搜索标签相关处理js代码开始--> <script>    /**    * 展示分类和搜索标签对象    * @type {{index: {index: number}, getEditClassify: goodsClassifyAndSearchTag."getEditClassify"}}    */   var goodsClassifyAndSearchTag = {     "index": 1,     "getFirstLevelClassify": function () { /** 获取一级展示类目,新增时父页面调用入口 **/     var url = '/showClassify/getClassifyByPid?pid=' + 0;
