Question

我有json

[{
    "_id": {
        "$oid": "57d23f407d033458a7cf4229"
    },
    "employeeCode": "E1",
    "dateFrom": "12/08/2016",
    "dateTo": "30/08/2016",
    "level": "1",
    "partyCode": "P1",
    "partyEmployeeId": "57d23f407d033458a7cf4229"
}, {
    "_id": {
        "$oid": "57d23f407d033458a7cf422a"
    },
    "employeeCode": "E2",
    "dateFrom": "07/09/2016",
    "dateTo": "",
    "level": "1",
    "partyCode": "P1",
    "partyEmployeeId": "57d23f407d033458a7cf422a"
}]

我通过

将这个json传递给我的模板

var compiledTemplate = _.template( myTemplate,{party:JSON.stringify(party)});
    this.$el.html( compiledTemplate );

我的模板代码是

<%  _.each(party,function(employee,index,list){ %>
<tr class="employees">
                    <td>
                    <span>
                        <input type="text" value="" class="employeeCode searchValuesOfTable" ><%= employee.employeeCode %></input>  
                        <img style="height:13px;" src="images/select.png" class="search">
                    </span>
                    </td>
                    <td>
                       <input type="text" value="" class="dateFrom searchValuesOfTable datePickers" placeholder="dd/mm/yyyy"><%= employee.dateFrom %></input>   
                    </td>
                    <td>
                        <input type="text" value="" class="dateTo searchValuesOfTable datePickers"  placeholder="dd/mm/yyyy"><%= employee.dateTo %></input> 
                    </td>


<% }) %>

但它创建了很多表格行并且不打印该值。请帮我弄清楚错误

不应该执行stringify，它会将JSON转换为我们无法通过键访问元素的字符串。

此外，您正在使用“partyEmployee”访问模板中的“派对”引用将json数据传递给模板。

只需更改js代码即可。

var template = _.template(myTemplate);
template({partyEmployee : party});
