防止纸张对话框自动关闭 [英] Prevent paper-dialog from automatically closing

问题描述

您好：

我在网页上有一个纸质对话 ：

 < paper-dialog ... id = autom_desc_dialogautoCloseDisabled> 
 ... 
< paper-button ... id =automatizar肯定自动对焦禁用>< / paper-button> 
< / paper-dialog> 
  

我有一个事件侦听器处理纸按钮 click：

  var auto_btn = querySelector（'＃automatizar'）; 
 auto_btn.on [click]。listen（（Event e）{
 // Some AJAX stuff 
}）; 
  

我想要的是在某些情况下，为了能够防止对话框关闭，已尝试 event.preventDefault（）， event.stopImmediatePropagation（）， event.stopPropagation ）但未成功。

您不需要删除用于布局的肯定/忽略属性。聚合物对话框文件是错误的（我打开了一个GH问题）closeSelector的默认值是'[拒绝]，[肯定]'而不是，你只需要设置closeSelector为，它不会关闭单击按钮的对话框。

Hello:

I have a paper-dialog element in a page:

<paper-dialog ... id="autom_desc_dialog" autoCloseDisabled> 
    ...
    <paper-button ... id="automatizar" affirmative autofocus disabled></paper-button>
</paper-dialog>

and I have an event listener that handles the paper-button click:

var auto_btn = querySelector('#automatizar');
auto_btn.on["click"].listen((Event e) {
    // Some AJAX stuff
});

What I want is that in some cases, to be able to prevent the dialog from closing, I've tried event.preventDefault(), event.stopImmediatePropagation(), event.stopPropagation() but no success.

Thanks in advance.

解决方案

You don't need to remove affirmative/dismissive attributes as they are used for layout. Polymer dialog docs are wrong (I've opened a GH issue) the default value for closeSelector is '[dismissive],[affirmative]' and not "", you just need to set closeSelector to "" and it won't close the dialog on clicking the buttons.
