在Handlebars中遍历数组对象 [英] Iterating over array of objects in Handlebars
问题描述
我实际上是在一个JSON对象中做这件事,但对于这个问题,我会简化。我似乎无法让我的Handlebars模板正确构建。这里是我传递的一个对象样本数组:
var data = {
DocumentInfo:[
{
类别:常规,
DocumentList:[
{
文档名称:文档名称1-常规,
DocumentLocation:文档位置1 - 常规
,
{
文档名称:文档名称2-常规,
DocumentLocation:文档位置2-常规
}
]
},
{
类别:单元文档,
DocumentList:[
{
文档名称:文档名称1-单元文档,
DocumentList:文档位置1-单元文档
}
},
{
类别:分钟
}
]
};
这里是Handlebars模板和Div的发展方向:
< div id =DocumentResults>< / div>
< script id =document-templatetype =text / x-handlebars-template>
< div>
{{#if DocumentInfo}}
{{#DocumentInfo}}
{{#Category}}
< div class =row>
< div class =col-md-12>
< h2> {{this}}< / h2>在{{DocumentLocation}}上的
{{#DocumentList}}
< p> {{DocumentName}}< / p>
{{/ DocumentList}}
< / div>
< / div>
{{/ Category}}
{{/ DocumentInfo}}
{{else}}
< p>目前没有文件可用< / p>
{{/ if}}
< / div>
< / script>
最后,这里是构建Handlebars输出的JavaScript:
var source = $ .trim($(#document-template)。html());
var template = Handlebars.compile(source);
var $ docData = $(template(data));
$(#DocumentResults)。empty()。append($ docData);
问题是,唯一产生的是标题字段。为什么它不会遍历每个类别的其他数组(DocumentList)?而且,我可以显示标题值的唯一方法是使用{{this}}。如果我用{{Category}}替换它,则不显示任何内容。我看不到这是什么,我在这里做错了。
检查此jsfiddle: http://jsfiddle.net/KPCh4/ var source = $(#document-template)。html();
var template = Handlebars.compile(source);
var html = template(data);
$('#DocumentResults')。html(html);
我仍然专注于迭代{{#each}}; #
实际上是一条捷径。不要混淆 {{Category}}
和 {{#Category}}
。前者输出一个属性的值;后者是一个列表(见#
)。
我让你对代码片段进行细化:)
希望这有助于,

I'm actually doing this in a JSON object but for this question, I will simplify. I can't seem to get my Handlebars template to build correctly. Here is a sample array of objects that I am passing:
var data = {
DocumentInfo: [
{
Category: "General",
DocumentList: [
{
DocumentName: "Document Name 1 - General",
DocumentLocation: "Document Location 1 - General"
},
{
DocumentName: "Document Name 2 - General",
DocumentLocation: "Document Location 2 - General"
}
]
},
{
Category: "Unit Documents",
DocumentList: [
{
DocumentName: "Document Name 1 - Unit Documents",
DocumentList: "Document Location 1 - Unit Documents"
}
]
},
{
Category: "Minutes"
}
]
};
Here is the Handlebars template and Div where it's going:
<div id="DocumentResults"></div>
<script id="document-template" type="text/x-handlebars-template">
<div>
{{#if DocumentInfo}}
{{#DocumentInfo}}
{{#Category}}
<div class="row">
<div class="col-md-12">
<h2>{{this}}</h2>
{{#DocumentList}}
<p>{{DocumentName}} at {{DocumentLocation}}</p>
{{/DocumentList}}
</div>
</div>
{{/Category}}
{{/DocumentInfo}}
{{else}}
<p>There are no documents available at this time</p>
{{/if}}
</div>
</script>
Finally, here is the JavaScript that builds the Handlebars output:
var source = $.trim($("#document-template").html());
var template = Handlebars.compile(source);
var $docData = $(template(data));
$("#DocumentResults").empty().append($docData);
The problem is, the only thing that is generated are the header fields. Why won't it iterate over my other array (DocumentList) for each Category? And, the only way I can get the header values to display is to use {{this}}. If I replace it with {{Category}} nothing displays. I can't see what it is that I'm doing wrong here.
Check this jsfiddle: http://jsfiddle.net/KPCh4/
var source = $("#document-template").html();
var template = Handlebars.compile(source);
var html = template(data);
$('#DocumentResults').html(html);
I were still focused on {{#each}} for iteration; #
is a shortcut actually. Do not confuse {{Category}}
and {{#Category}}
. The former output a property's value; the latter is a list (see the #
).
I let you fine-grained the snippet :)
Hope this helps,
R.
