RE： jquery选择器点击不动态生成的按钮触发

我使用以下代码来检测动态生成的按钮何时被点击。

  $（document）.on click，。appDetails，function（）{
 alert（test）; 
}）; 
  

通常情况下，如果你只是$（'appDetails'）。 （this）获取被点击的元素。

例如：

  $（document）.on（click，。appDetails，function（）{
 var clickedBtnID = ?????? 
 alert（'you clicked on button＃'+ clickedBtnID ）; 
}）; 
  

解决方案

b
$ b

使用 $（this）此处

  $（document）.on（click，。appDetails，function（）{
 var clickedBtnID = $（this）.attr（'id'）; //或var clickedBtnID = this .id 
 alert（'you clicked on button＃'+ clickedBtnID）; 
}）; 
  

UPDATE 2016-08-31 This is closed but popular, so I'm editing to hopefully clean some things up. The original issue I actually had turned out to be a caching problem. I have removed all that so the question and answers make more sense together and I have accepted the top answer. Hopefully this will be useful to someone.

RE: jquery selector click not firing from dynamically generated button?

I'm using the following code to detect when a dynamically generated button is clicked.

$(document).on("click",".appDetails", function () {
    alert("test");
});

Normally, if you just did $('.appDetails').click() you could use $(this) to get the element that was clicked on. How would I accomplish this with the above code?

For instance:

$(document).on("click",".appDetails", function () {
    var clickedBtnID = ??????
    alert('you clicked on button #' + clickedBtnID);
});

解决方案

as simple as it can be

use $(this) here too

$(document).on("click",".appDetails", function () {
   var clickedBtnID = $(this).attr('id'); // or var clickedBtnID = this.id
   alert('you clicked on button #' + clickedBtnID);
});
