动态添加的单选按钮onclick事件不起作用？ [英] dynamically added radio buttons onclick event not working?

问题描述

我正在尝试
1.从用户选择中使用Ajax获得响应，这将单选按钮属性列表作为
返回给我2.一旦获得属性列表，我就创建了收音机使用createElement（）
按钮。3.然后将事件附加到onclick按钮的单选按钮。
4.然后，我使用pedChild

I am trying following, 1. Get response using Ajax from the users selection which returns me the list of the radio buttons attributes as 2. Once i get the attribute list i am creating the radio buttons using createElement() 3. Then i am attaching the event to the radio button for onclick buttons. 4. Then i add element to the DOM using appedChild

将元素添加到DOM中，下面是添加单选按钮（对于IE）的代码

The below is code for adding radio button (for IE)

var radio = '<input ';
radio += 'type ="radio" ';
radio += 'id="' + id + '" ';
radio += 'value="" ';
radio += '/>';
radioButton = document.createElement(radio);
radioButton.onClick = function(){alert('this is test')}
ele.appendChild(radioButton);
ele.innerHTML += 'none' + '<br/>';

现在，当我向DOM中添加单选按钮时，onclick不起作用，我不知道不明白为什么？

Now in all this when i am adding the radio button to the DOM onclick is not working and i don't understand why ?

谢谢

推荐答案

您可以动态地通过两种方式向DOM中添加en元素：通过将html代码插入父元素或通过创建具有某些属性的子元素。在您的示例中，这两种方法是混合的，因此毫无意义。

You can dynamically add en element to the DOM by two ways: by inserting an html code into the parent element or by creating a child element with some properties. In your example the two methods are mixed - therefore senseless.

方法1.插入HTML代码：

Method 1. Inserting HTML code:

var radio = '<input type ="radio" id="' + id + '" value="" />';
ele.innerHTML = radio;
document.getElementById(id).onclick = function(){ alert('this is test'); };

方法2。创建DOM子级：

Method 2. Creating DOM child:

var radioButton = document.createElement('input');
radioButton.type = "radio";
radioButton.id = id;
radioButton.onclick = function(){ alert('this is test'); };
ele.appendChild(radioButton);
