我的解决方案:
- 在聚合物上引发事件(例如
complete
)
- 定义将事件链接到控制功能的指令
指示
/*global define */
define(['angular', './my-module'], function(angular, directives) {
'use strict';
directives.directive('polimerBinding', ['$compile', function($compile) {
return {
restrict: 'A',
scope: {
method:'&polimerBinding'
},
link : function(scope, element, attrs) {
var el = element[0];
var expressionHandler = scope.method();
var siemEvent = attrs['polimerEvent'];
if (!siemEvent) {
siemEvent = 'complete';
}
el.addEventListener(siemEvent, function (e, options) {
expressionHandler(e.detail);
})
}
};
}]);
});
聚合物成分
<dom-module id="search">
<template>
<h3>Search</h3>
<div class="input-group">
<textarea placeholder="search by expression (eg. temperature>100)"
rows="10" cols="100" value="{{text::input}}"></textarea>
<p>
<button id="button" class="btn input-group__addon">Search</button>
</p>
</div>
</template>
<script>
Polymer({
is: 'search',
properties: {
text: {
type: String,
notify: true
},
},
regularSearch: function(e) {
console.log(this.range);
this.fire('complete', {'text': this.text});
},
listeners: {
'button.click': 'regularSearch',
}
});
</script>
</dom-module>
页
<search id="search" polimer-binding="searchData"
siem-event="complete" range="{{range}}"></siem-search>
searchData
是控制功能
$scope.searchData = function(searchObject) {
alert('searchData '+ searchObject.text + ' ' + searchObject.range);
}
