添加onclick事件来动态添加按钮？ [英] adding onclick event to dynamically added button?

问题描述

我在html中动态添加一个按钮，如下所示：
单击该按钮我想调用一个Javascript函数：

I am adding a button dynamically in html like below: On click of that button I want to call a Javascript function:

var but = document.createElement("button");

but.value="delete row";

but.setAttribute("onclick","callJavascriptFunction()");
//this is not working

but.onclick="callJavascriptFunction()"
//this is also not working

document.getElementById("but").onclick="callJavascriptFunction()"
//this is also not working

but.id="but"+inc;

有没有什么办法可以解决这个问题?? Plz帮助我，
先谢谢了

Are there any ways to resolve this??Plz help me., thanks in advance

推荐答案

试试这个：

try this:

but.onclick = callJavascriptFunction;

或者通过用另一个元素包装并使用innerHTML来创建按钮：

or create the button by wrapping it with another element and use innerHTML:

var span = document.createElement('span');
span.innerHTML = '<button id="but' + inc +'" onclick="callJavascriptFunction()" />';
