Javascript 如何获得；“确认”；纸张对话框聚合元素的返回值？

请参见聚合物应用程序中的以下html：

<paper-dialog id="confirmation" modal auto-fit-on-attach>
    <h2><spring:message code="confirmation" /></h2>
    <p>Are you sure ?<p>
    <div class="buttons">
        <paper-button dialog-confirm><spring:message code="yes" /></paper-button>
        <paper-button dialog-dismiss><spring:message code="no" /></paper-button>
    </div>
</paper-dialog>

如何从对话框中获取“已确认”的返回值？

您通常会将一个处理程序附加到对话框上的

iron overlay closed

事件，以确定它是否已确认，因为纸张对话框实现了

比如：

<template is="dom-bind" id="scope">
    <paper-dialog id="confirmation" modal auto-fit-on-attach on-iron-overlay-closed="dismissDialog">
        <h2><spring:message code="confirmation" /></h2>
        <p>Are you sure ?<p>
        <div class="buttons">
            <paper-button dialog-confirm><spring:message code="yes" /></paper-button>
            <paper-button dialog-dismiss><spring:message code="no" /></paper-button>
        </div>
    </paper-dialog>
</template>

<script>
  (function() {
    var scope = document.querySelector('#scope');

    scope.dismissDialog = function(e) {
      console.log(e.detail.confirmed);

      if (e.detail.confirmed) {
        // confirmed logic goes here
      }
    }
  })();    
</script>

你确定吗？
（功能（）{
var scope=document.querySelector（“#scope”）；
scope.dismissDialog=函数（e）{
控制台日志（如详细信息已确认）；
如果（如详细信息已确认）{
//确认的逻辑在这里
}
}
})();    

<template is="dom-bind" id="scope">
    <paper-dialog id="confirmation" modal auto-fit-on-attach on-iron-overlay-closed="dismissDialog">
        <h2><spring:message code="confirmation" /></h2>
        <p>Are you sure ?<p>
        <div class="buttons">
            <paper-button dialog-confirm><spring:message code="yes" /></paper-button>
            <paper-button dialog-dismiss><spring:message code="no" /></paper-button>
        </div>
    </paper-dialog>
</template>

<script>
  (function() {
    var scope = document.querySelector('#scope');

    scope.dismissDialog = function(e) {
      console.log(e.detail.confirmed);

      if (e.detail.confirmed) {
        // confirmed logic goes here
      }
    }
  })();    
</script>
