我用来从公共API返回响应。我的问题是API返回了一个对象,而Polymer不允许我们对一个对象进行dom-repeat。我真的在尝试访问该对象中的数组,是否有某种方法可以从返回的对象中提取该数组并对该数组进行dom-repeat?如果不是的话,还有没有其他方法可以访问聚合物的响应?谢谢!
最佳答案
您必须使用{{response.players}}
代替{{response}}
中的dom-repeat
。这是一个工作示例。
<!DOCTYPE html>
<html>
<head>
<title>paper-scroll-header-panel not working</title>
<script src="https://rawgit.com/webcomponents/webcomponentsjs/master/webcomponents.js"></script>

<!--<link rel="import" href="all-elements.html">-->
</head>
<body class="fullbleed">
<test-elem></test-elem>
<dom-module id="test-elem">
<template>
<iron-ajax auto
url='http://api.fantasy.nfl.com/v1/players/stats'
handle-as="json"
last-response="{{response}}"></iron-ajax>
<template is="dom-repeat" items="{{response.players}}">
<paper-material class="add-players">
<div class="layout horizontal center">
<h2>{{item.name}}</h2>
</div>
</paper-material>
</template>
</template>
<script>
Polymer({
is : "test-elem"
});
</script>
</dom-module>
</body>
</html>
