How to get get route param values in template? 如何在模板中获取路由参数值?
Router 路由器
Router.map(function() {
this.route('userpost', {path: '/mypost/:_id'});
this.route('usercomment', {path: '/mycomments/:_id'});
});
my current location is localhost:3000/mypost/12345
. 我当前的位置是
localhost:3000/mypost/12345
。 I want to assign a path parameter from a route param 我想从路由参数中分配路径参数
Template 模板
<template name="mytemplate">
<a class="tab-item" href="{{pathFor 'userpost' _id=???}}">Post</a>
<a class="tab-item" href="{{pathFor 'usercomment' _id=???}}">Comment</a>
</template>
{{pathFor}}
is using the current data context to replace URL parameters with actual values, so you need to enclose the call inside a {{#with}}
block helper. {{pathFor}}
使用当前数据上下文将URL参数替换为实际值,因此您需要将调用括在{{#with}}
块帮助器中。
<template name="mytemplate">
{{#with context}}
<a class="tab-item" href="{{pathFor "userpost"}}">Post</a>
<a class="tab-item" href="{{pathFor "usercomment"}}">Comment</a>
{{/with}}
</template>
context
is a helper returning an object that have an _id
, and this property will be used to fill-in the computed path. context
是一个帮助器,返回一个具有_id
的对象,该属性将用于填充计算出的路径。
Template.mytemplate.helpers({
context: function(){
return {
_id: Router.current().params._id
};
}
});
