mustache.js实现首页元件动态渲染的示例代码

(编辑：jimmy 日期: 2024/12/23 浏览：3 次 )

前言

在项目开发过程中，特别是OA类软件，会针对邮件/待办/公告等模块在主页面进行快捷查看的元件展示要求，类似效果如下

"text-align: center">"text-align: center">"text-align: center">"htmlcode">

<div class="cellheadcontainer">
 <span class="celltitletext">{{elementtitle}}</span>
 <div class="celltitleop">
  <a style="color:white" class="morebtn" onclick="OpenMore('{{elementmoreurl}}')">更多</a>
 </div>
</div>
<div class="cellcontentcontainer">
 {{#data}}
 <div class="notciecell" onclick="OpenDetail('{{title}}')">
  <div class="noticeleft">
   <span class="noticetitle noticeindex">{{index}}</span>
   <span class="noticetitle">{{title}}</span>
  </div>
  <div class="noticeright">
   <span class="noticetip">{{publishuname}}</span> 
   <span class="noticetip">{{publishdate}}</span>
  </div>
 </div>
 {{/data}}
</div>
<script>
 var noticeid = "{{elementid}}";
 function OpenMore(url) {
  OpenTopDialog( '消息通知列表', url, 600, 800, BindNotcieList)
 }
 function BindNotcieList() {
  CommonRefresh(noticeid);
 }
 function OpenDetail(title) {
  OpenTopDialog('消息详情', "frame/demo/notice/noticeDetail", 600, 800, BindNotcieList, title)
 }
</script>

主页面模板渲染

主要是针对当前配置的模板进行分组，渲染每行每列的元件，模板文字内容在后端处理获取完成，前端调用Mustache.render方法进行数据的填充，同时需要注意针对每个元件定义局部刷新的方法，避免操作完毕后针对主页面整体刷新

<body>
 <div id="app">
  <div id="maincontainer">
   <div class="rowcontainer">
    <div class="columncontainer">

    </div>
   </div>
  </div>
 </div>
 <script>
  loadcss(getRootPath() + "theme/" + GetSystemTheme() + "/main.css", true)
 </script>
 <script>
  var pageData = {
   ElementList: [],
   groupCount: 0,
   rowElementCount: 2
  };
  $(function () {
   BindElement();
  })

  function BindElement() {
   var param = {};
   CloudPost(param, GetRootPath() + "frame/extend/element/findMainPageElementList", function (res) {
    if (res.code == 0) {
     pageData.ElementList = res.data;
     var rowelementcount = pageData.rowElementCount
     var groupcount = pageData.ElementList.length % rowelementcount == 0 "";
     for (var i = 0; i < groupcount; i++) {
      var RowHtml = " <div class='rowcontainer'>";
      for (var j = 0; j < rowelementcount && i * groupcount + j < pageData.ElementList.length; j++) {
       var id = "row_" + (i + 1) + "column_" + (j + 1);
       var ColumnHtml = "<div class='columncontainer' id='" + id + "'>"
       ColumnHtml += "</div>"
       RowHtml += ColumnHtml;
      }
      RowHtml += "</div>";
      MainHtml += RowHtml;
     }
     $("#maincontainer").html(MainHtml);

     for (var i = 0; i < groupcount; i++) {
      for (var j = 0; j < rowelementcount && i * groupcount + j < pageData.ElementList.length; j++) {
       var index = i * rowelementcount + j
       var element = pageData.ElementList[index];
       var id = "row_" + (i + 1) + "column_" + (j + 1);
       pageData.ElementList[index]["ElementID"] = id;
       var renderdata = {
        elementtitle: element.ElementName,
        elementmoreurl: element.ElementMoreUrl,
        elementid: id
       }
       //刷新事件存储

       pageData.ElementList[index]["RefreshEvent"] = function () {
        //请求数据
        CloudPost({}, GetRootPath() + element.ElementDataUrl,
         function (res) {
          if (res.code == 0) {
           //合并json
           for (var attr in res) {
            renderdata[attr] = res[attr];
           }
           var htmlcontent = Mustache.render(element.TemplatContent, renderdata);
           $("#" + id).html(htmlcontent);
          }
         })
       }
       //请求数据
       CommonRefresh(id);
      }
     }
    } else {
     OpenFail(res.data)
    }
   })
  }

  function CommonRefresh(id) {
   $(pageData.ElementList).each(function () {
    if (this.ElementID == id) {
     this.RefreshEvent();
    }
   })
  }
 </script>

</body>
