Template repeat inside template repeat - 获取所有项目名称
Template repeat inside template repeat - get all item names
我正在尝试使用 polymer 1.0 实现一个网站。
我有一个自定义元素 my-greeting,里面有一些模板重复。
我想做的是获取一个名为 TARGET 的字符串,如下所示:
/constantPath/folder1/aaa.jpg
/constantPath/folder1/bbb.jpg
/constantPath/folder2/aaa.jpg
/constantPath/folder2/bbb.jpg
所以一般的字符串是:/constantPath/{{repeat1.id}}/{{repeat2.id}}.jpg
我该怎么做??
这是我的代码:
<dom-module id="my-greeting">
<template>
<template is="dom-repeat" items="{{repeat1}}">
<template is="dom-repeat" items="{{repeat2}}">
Target : <iron-image src="TARGET"></iron-image>
</template>
</template>
</template>
<script>
Polymer({
is: 'my-greeting',
ready: function() {
this.repeat1 = [
{id: 'folder1'},
{id: 'folder2'}
];
this.repeat2 = [
{id: 'aaa'},
{id: 'bbb'}
];
}
}
);
</script>
谢谢。
给你:
<dom-module id="my-greeting">
<template>
<template is="dom-repeat" items="{{repeat1}}" as="folderOne">
<template is="dom-repeat" items="{{repeat2}}" as="folderTwo">
Target : <span>{{getTarget(folderOne, folderTwo)}}</span></br>
</template>
</template>
</template>
<script>
Polymer({
is: 'my-greeting',
ready: function() {
this.repeat1 = [
{id: 'folder1'},
{id: 'folder2'}
];
this.repeat2 = [
{id: 'aaa'},
{id: 'bbb'}
];
},
getTarget: function(folderOne, folderTwo){
return "/constantPath/"+folderOne.id+"/"+folderTwo.id;
},
}
);
</script>
</dom-module>
