如何修改粘贴事件的结果？

时间：2021-05-24 23:52:14

So I have a custom textbox directive (it contains an input box inside).

所以我有一个自定义文本框指令(它包含一个输入框)。

<custom-textbox ng-paste=pasteFn($event)></custom-textbox>

When the user hits paste, I want to sanitize what was pasted (removes special characters + reduces the string length).

当用户点击粘贴时,我想清理粘贴的内容(删除特殊字符+减少字符串长度)。

I tried looking into the event object and it looks fairly large, so I'm not sure of the best way to modify this string.

我尝试查看事件对象,它看起来相当大,所以我不确定修改此字符串的最佳方法。

Get the clipboard data and send it to your paste function like this:

获取剪贴板数据并将其发送到您的粘贴功能,如下所示:

        <input ng-paste="clean($event.clipboardData.getData('text/plain'))" placeholder='paste here' ng-model="paste">
pasted: {{paste}}<br>
new string: {{myString}}

Then in your controller:

然后在你的控制器中:

    $scope.clean = function(e){
  var str = e;

 $scope.myString = str.replace(/[^a-zA-Z ]/g, "");
  }
