详解velocity模板使javaWeb的html+js实现模块化
页面上一些基础数据或者其他页面经常用到部分,可以独立出来做成小组件,组件预留调用入口,需要的页面直接调用即可。
如图,页面中的展示分类和搜索标签在多个页面重复使用,可以将这部分内容独立出来,做成组件,供后续开发调用:
classify_search_tag.html文件如下,其中包含HTML节点和jQuery代码;
<!-- 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"GET"};

} } return classify; } } } </script>
调用页面的HTML文件中该模块的位置用velocity引用该组件:
#parse("/classify_search_tag.html")
调用页面的js文件中,调用入口方法即可:
新增调用
$(function () { goodsClassifyAndSearchTag.getFirstLevelClassify();/** 初始化一级展示分类 **/ });
编辑调用:
$(function () { goodsClassifyAndSearchTag.getClassifyAndSearchTag("需要的参数");/** 回显展示类目以及搜索标签 **/ });
获取选中的返回值:
goodsClassifyAndSearchTag.returnSelectedClassifyAndTag()
