流星设置整体模板上下文
问题描述:
在meteor中,我可以像这样设置各种模板助手:
In meteor I can set various template helpers like this:
Template.story.title = function () {
return "title";
};
<template name="story">
<h3>{{title}}</h3>
<p>{{description}}</p>
</template>
哪个好,但是,如果我有很多变量,我不想单独设置它们,我想将上下文传递给主模板。
Which is great but, if I have a lot of variables I wouldn't want to set them individually, I want to pass the context to the main template.
我该怎么做?
Template.story.data = function () {
return {title:"title", description:"desc"};
};
<template name="story">
<h3>{{title}}</h3>
<p>{{description}}</p>
</template>
这不起作用。谢谢

您可以在调用时设置模板的上下文:
You can set the context of the template when you call it:
{{> story data}}
Template.outerTemplate.data = function() {
return {title:"title", description:"desc"};
}
或者你可以使用 {{#with} }
即时设置模板上下文:
Or you can just use {{#with}}
to set the the template context on the fly:
{{#with data}}
{{title}}
{{/with}}
