在模板内部阵列流星中显示

I'm working with Meteor and want to reach values that are stored in a field which functions as an internal array.

我正在使用Meteor,并希望获得存储在作为内部数组的字段中的值。

When I run the query (with projection) I get one record which looks like that:

当我运行查询(带投影)时,我得到一条看起来像这样的记录:

{ "comments" : [ { "uid" : "1", "un" : "Sarah", "c" : "cc" }, { "uid" : "2", "un" : "Leo", "c" : "dd" } ] }

I need to show in a template "un" and "c" of each record in the array. I tried that:

我需要在数组中的每个记录的模板“un”和“c”中显示。我试过了:

html:

<template name="allComments">
    <ul>
        {{#each allC}}
            <li>{{un}}</li>
        {{/each}}
    </ul>
</template>

js:

Template.allComments.allC = function () {
    //query that returns result as above
}

I've tried also {{#with}}, nested {{#each}} and nested templates but it doesn't work..

我也尝试了{{#with}},嵌套{{#each}}和嵌套模板,但它不起作用..

How can I reach this value?

我怎样才能达到这个值?

Thanks a lot, Sarah.

非常感谢,莎拉。

Try changing your JS:

尝试更改你的JS:

Template.allComments.helpers({
  allC: function() {
    //query that returns result as above
  }
});

'#each' should then work in your template.

然后'#each'应该在你的模板中工作。

I finally managed to show this comments with:

我终于设法用这样的评论来表达:

Template.allComments.helpers({
allC: function () {
    var result=[];
    TasksList.findOne({_id:Session.get('selectedID')})['comments'].forEach(function(entry){
        result.push(entry['un']+entry['c']);
        });
    return result;
    },});

and

<template name="allComments">
<ul>
    {{#each allC}}
        <li>{{this}}</li>
    {{/each}}
</ul>
