动态评估模板

Question

-使用流星框架--

嗨，我想通过Template["tViewPost"]访问下面的模板

<template name="tViewPost">
    <div class="breadcrumb">
        <span>{{title}}</span>&lsaquo;&lsaquo;<span>{{subttile}}</span>
    </div>
</template>

并且能够使用像{ title : "My title", subttitle : "othe subtitle"};这样的javascript对象来呈现/评估这个模板，但是我不知道如何实现它，一旦我在变量中有了模板，我想要像下划线库那样做。

var template = _.template("whatever <%= title %>");
var o = {title : "ohhh!"};
$("someDomElement").html(template(o))

这样做有可能吗？怎么做呢？谢谢..。

您可以使用Meteor.render (来自docs)尝试这样做：

// Client side: show the number of players online.
var frag = Meteor.render(function () {
  return "<p>There are " + Players.find({online: true}).count() +
    " players online.</p>";
});
document.body.appendChild(frag);

// Server side: find all players that have been idle for a while,
// and mark them as offline. The count on the screen will
// automatically update on all clients.
Players.update({idleTime: {$gt: 30}}, {$set: {online: false}});

编辑：

// returns string which contains html
Meteor.render(Template['name'](dataObject))


// your case:
<template name="test">
   whatever {{title}}"
</template>

var o = {title : "ohhh!"};

$("someDomElement").html(Meteor.render(Template['test'](o)))
