我创建了一个表格,您可以在其中添加文本并对其进行编辑。 但是,如果你添加超过三行,它就会卡住而不再工作。
错误来自: document.getElementById('vda'+ z).addEventListener('click',doSomething); document.getElementById('cvda'+ z).addEventListener('click',doSomething2);
只添加事件监听器到最后一行添加,因此如果添加多行。最后一行没有工作编辑按钮。
我通过检查编辑和更新按钮元素来检查ID。 尝试添加3行,然后单击其中一行的编辑按钮。 您可以在此处查看代码以及https://jsfiddle.net/3e6d4qsv/

答案 0 :(得分:0)
以下行删除所有侦听器:
document.getElementById(“buttons”)。innerHTML = document.getElementById(“buttons”)。innerHTML + total;
document.getElementById('vda'+ z).addEventListener('click', doSomething的);
改为使用:
var div = document.createElement('div');
div.innerHTML = total;
的document.getElementById( “按钮”)的appendChild(DIV);
