数据请求不到，接口返回是啥？dataList打印一下嘛，看看里面具体是啥我underscore不太熟你试试这样行不行。var templateTable2 = '<% _.each(dataList, function(n){ %>\&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <tbody><tr data-id="<%=n.id %>">\&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <th scope="row">\&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <input type="checkbox" id="<%=n.id %>"</th>\&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td><%=n.local %></td>\&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <td><%=n.upper %></td>\&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </tr></tbody><% });%>';&nbsp;var data= [{ id: 101,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; local:'联通',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; upper:'北京教育网'&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }, {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; id: 102,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; local:'电信',&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; upper:'北京教育网'&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}];&nbsp;var tpl = _.template(templateTable2)({ dataList:data });&nbsp;console.log(tpl);
