我有以下HTML:
<button type="button" id="Button">Go</button>
<div id="validation"></div>
我正尝试通过以下方式将事件处理程序添加到动态生成的元素中:
单击按钮->在div #validation中生成元素X->将事件处理程序附加到元素X
$(document).ready(function(){
ID = 1;
$("#Button").click(function(){
/*generate new div inside div #validation with id #validationID
1st one would be #validation1
it contains a form with name accepterID and a button with name refuserID
1st ones would be accepter1 and refuser1*/
var newline = `
<div id="validation${ID}">
<form name="accepter${ID}">
<input type="hidden" name="name" value="phoegasus">
<button type="submit" value="valider">
</form>
<button name="refuser${ID}">refuser</button>
</div>
`
$("#validation").append(newline);
/*attach event handlers to the generated elements
1st iteration would attach handlers to accepter1 and refuser1 */
$("#validation").on('submit',"form[name^='accepter"+ID+"']",function(e){
$("#validation" + ID).remove();
//remove div validationID after submitting form
});
$("#validation").on('click',"button[name^='refuser"+ID+"']",function(){
$("#validation" + ID).remove();
//remove div validationID
});
ID++;
});
});
当我提交表单或单击生成的按钮时,我要删除包含它们的div。如果我按下按钮rejectr1,它应该删除div#validation1。
生成元素时,不会将处理程序附加到它们。
该代码在onclick事件中执行时不起作用,但是当我在导航器控制台中执行时,它起作用。
我尝试在ID为#validation的div上使用DOMSubtreeModified,但是没有用。

您可以通过在on
函数的第二个参数中使用类(或其他元素)来对其进行管理。
为此,请勿在添加事件中声明事件监听器。
这是一个完整的示例:
$("#validation").on('submit',"form.validation-form",function(e){
e.preventDefault();
console.log('form', $(this).attr('data-id'), ' submitted');
});
$("#validation").on('click',"button.validation-refuser",function(){
console.log('clicked on refuser for form ', $(this).attr('data-value'));
//code
});
var ID = 1;
$('#my-adder').on('click', function () {
$('#validation').append('<form name="accepter'+ID+'" class="validation-form" data-id="'+ID+'"><input type="text" placeholder="my text field" /><button class="validation-refuser" name="refuser'+ID+'" data-value="'+ID+'">Refuser button</button><button type="submit">SUBMIT</button></form>');
ID++;
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="validation">
<form name="accepter0" class="validation-form" data-id="0">
<input type="text" placeholder="my text field" />
<button type="button" class="validation-refuser" name="refuser0" data-value="0">Refuser button</button>
<button type="submit">SUBMIT</button>
</form>
</div>
<button id="my-adder">ADD A FORM</button>
希望有帮助
