从动态创建的jQuery按钮获取文本值

Question

因此，我根据从generateFolderTree函数返回的数组值向表中动态添加按钮，问题是当我单击创建的按钮时，我似乎无法获得被单击按钮的文本值，甚至无法获得任何事件。 如何获得单击按钮的名称？ 下面的代码...。谢谢

jQuery的

   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(function(){
$("#selectFolder").click(runMyFunction);
});
function runMyFunction(){
google.script.run
.withSuccessHandler(successCallback)
.withFailureHandler(showError)
.generateFolderTree();
 $("#hiddenAttrib").hide();
}

function showError(error) {
    console.log(error);
    window.alert('An error has occurred, please try again.');
  }
  function successCallback(returnedArray)
  {
    console.log("returnedArray" + returnedArray);
    var folders = returnedArray;
   console.log("folders" + folders);
    var i = 0;
    //row;
    for( i=0; i<folders.length;i++)
    {
       console.log("i = " + i);
   var row = $('<p><tr><button class = "selectedFolder">' + folders[i] + '</button></tr></p>');
    $("#source").append(row.html());
    }
  }
 $(".selectedFolder").click(function () {
var text = $(this).text();
console.log(text);
$("#dialog-status").val(text);
}); 


</script>

Answer 1

 $('document').on('click', '.selectedFolder', function () {

            alert($(this).text())
        });

Answer 2

将您的这段代码放在$（document）.ready中

$(".selectedFolder").click(function () {
var text = $(this).text();
console.log(text);
$("#dialog-status").val(text);
}); 

Answer 3

采用

$(ELEMENT/CLASS/ID).on('click', function(){});

代替

$(ELEMENT/CLASS/ID).click

在我们以前使用live()为动态创建的元素附加事件之前， click()函数不会考虑动态添加到DOM的元素，但是由于live()已被贬值，我们应该使用on（）

on()充当live()
