html - 如何从 HTML id 中保存值以便在 for 循环中进行比较

Question

我想在 for 循环中比较两个值，已经尝试使用 #tmpid.val，但不起作用。

<template name="productpendingstatus">

       {{#each totaltemplate}}

       <table class="table table-responsive table-bordered">

        <thead><tr><td colspan="3">{{this.META.TEMPLATE_NAME}}</td>

<td id="tmpid">{{this._id}}</td> <want to compare this value in code below>

</tr></thead>
        </table>
        <div class="pendingProducts">
          <table class="table table-responsive table-bordered">

            <tbody>


                {{#each productt}}
                {{#if $eq <value of id tmpid> this.TemplateID.value }}//this is ques

                <tr>
                  <td><input type="checkbox"></td>
                  <td>{{this.ProductId.value}}</td>

                </tr> 
                {{/if}}
                {{/each}}


            </tbody>

          </table>
       </div>
       {{/each}}



    </template>

要在模板中引用父数据上下文，空格键现在提供 the "../" notation :

<template name="productpendingstatus">
       {{#each totaltemplate}}
       <table class="table table-responsive table-bordered">
        <thead><tr><td colspan="3">{{this.META.TEMPLATE_NAME}}</td>
<td id="tmpid">{{this._id}}</td> <want to compare this value in code below>
</tr></thead>
        </table>
        <div class="pendingProducts">
          <table class="table table-responsive table-bordered">
            <tbody>
                {{#each productt}}
                {{#if $eq ../_id this.TemplateID.value }}
                <tr>
                  <td><input type="checkbox"></td>
                  <td>{{this.ProductId.value}}</td>
                </tr> 
                {{/if}}
                {{/each}}
            </tbody>
          </table>
       </div>
       {{/each}}
    </template>
