问题描述
我有一个简单的Polymer元素,可在dom-repeat
模板中使用.
I have a simple Polymer element, that I use in a dom-repeat
template.
<link rel="import" href="../../bower_components/polymer/polymer.html">
<dom-module id="flow-element" attributes="name kind">
<template>
<paper-material class="flow" elevation="1">
<span>
//delete button
<paper-button class="delete" on-click="handleClick({{name}})">
<iron-icon icon="delete" ></iron-icon>
</paper-button>
</span>
<paper-item id="name">{{name}}</paper-item>
<paper-item id="kind">{{kind}}</paper-item>
</paper-material>
<!-- data bindings in local DOM -->
</template>
<script>
Polymer({
is: 'flow-element',
handleClick: function(name) {
console.log('clicked: ');
// remove the item
delete flowListID.flowDictionnary[name];
}
});
</script>
</dom-module>
如何访问名称值,以便将其从flowDictionnary
词典中删除?我尝试使用JQuery做到这一点,但我不知道如何在Polymer({...})函数内插入Jquery代码.是的,我是Web开发人员的新手.
How can I access the name value so I can remove it from the flowDictionnary
dictionary ? I tried to do it using JQuery but I don't know how insert the Jquery code inside the Polymer({...}) function. And yes, I'm new to web dev.
推荐答案
这应该有效.
<link rel="import" href="../../bower_components/polymer/polymer.html">
<dom-module id="flow-element">
<template>
<paper-material class="flow" elevation="1">
<span>
//delete button
<paper-button class="delete" on-click="handleClick">
<iron-icon icon="delete" ></iron-icon>
</paper-button>
</span>
<paper-item id="name">{{name}}</paper-item>
<paper-item id="kind">{{kind}}</paper-item>
</paper-material>
<!-- data bindings in local DOM -->
</template>
<script>
Polymer({
is: 'flow-element',
properties:{name:{type:String},kind:{type:String}}
handleClick: function() {
console.log('clicked: '+this.name);
//if flowListID is a global variable declared outside of your element
// you can access it anywhere
// in other case you can pass this variable to this element and refeer
// it using this. As follows: delete this.flowListID.flowDictionnary[name];
// remove the item
//delete flowListID.flowDictionnary[name];
}
});
</script>
</dom-module>
