在循环中访问外部#each 集合值的标准方法是什么?例如:
What is the standard way to access outer #each collection values in the loop? for example:
<template name="example"> {{#each outerCollection}} <tr> {{#each innerCollection}} <td>{{aaa}}</td> {{/each}} </tr> {{/each}} </template> Template.example.aaa = function(){ // cannot access outerCollection values }在上面的 Template.example.aaa 中,this 指向内部集合.
in above Template.example.aaa, this points to the inner collection.
我找不到访问 outerCollection 项目的方法.我的解决方案如下所示,我正在定义自己的辅助函数.是不是标准的 Meteor 方式来达到这个目的?
I cannot find way to access outerCollection items. My solution is like below, I am defining my own helper function. Is it a standard Meteor way to achieve this purpose?
<template name="example"> {{#each outerCollection}} <tr> {{#each innerCollection}} <td>{{myHelper ../outerItem innerItem}}</td> {{/each}} </tr> {{/each}} </template> Handlebars.registerHelper('myHelper', function (outItem, inItem) { // can access outerCollection via outerItem });我发现了一个类似的问题内部事件处理程序访问的情况.
I found a similar question for the case of inner event handler access.
推荐答案我想你自己已经回答了这个问题!使用 ../ 记录在 github/meteor/meteor/wiki/Handlebars.
I think you've answered this yourself! Using ../ is documented in github/meteor/meteor/wiki/Handlebars.
