根据答案here，我一直在尝试将一个jQuery插件（addtocalendar）包装在一个angular指令中。我正在使用ui-router，以前插件可以工作，但如果我从这个孩子导航到另一个状态，addtocalendar按钮将完全消失。
现在，将插件包装在一个指令中，如果我导航到另一个子状态然后返回，我能够看到该按钮，但是，我从插件中得到一个错误，我指定了一个无效日期。似乎我从Angular提供插件的数据运行一次，然后再也不会被添加到插件中。
有解决方法吗？
这是我的HTML：
// works fine on first page load
<div addtocalendartest> // angular directive
<div class="addtocalendar"> //jQuery plugin
<div class="arrow-up"></div>
<var class="atc_event">
<var bind-once class="atc_date_start">{{event.startDate | date:'yyyy-MM-dd HH:mm:ss'}}</var>
<var bind-once class="atc_date_end">{{event.endDate | date:'yyyy-MM-dd HH:mm:ss'}}</var>
<var bind-once class="atc_timezone">America/New_York</var>
<var bind-once class="atc_title">{{event.description}}</var>
<var bind-once class="atc_description">{{event.Synopsis | characters: 200 :false }}</var>
<var bind-once class="atc_location">_</var>
</var>
</div>
</div>
这是我创建的包含插件逻辑的指令：
'use strict';
angular.module('myApp')
.directive('addtocalendartest', function() {
return {
restrict: 'A',
link: function(scope, element, attrs) {
//run jQuery scripts

}
}
return -1
}
}
if (!Array.prototype.map) {
Array.prototype.map = function(e) {
var t = [];
for (var n = 0, r = this.length; n < r; n++) {
t.push(e(this[n]))
}
return t
}
}

UPDATE / ANSWER 感谢@charlietfl，答案是包含$ timeout，以便Angular可以在jQuery插件之前加载，例如：
'use strict';
angular.module('myApp')
.directive('addtocalendartest', function($timeout) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
$timeout(function(){
// jQuery plugin logic goes here
}, 5000);
}
};
});
答案 0 :(得分：1)
使用$timeout让angular首先编译文本，以便插件不会尝试读取表达式。
$timeout(function(){
addtocalendar.load();
});
如果需要首先从服务器请求解析数据，您可以在路由器中使用resolve，以便在模板加载时存在
