在Safari中没有触发JQuery Click事件？ [英] JQuery Click event not being triggered in Safari?
问题描述
当用户从选择框中选择一个选项时，我正在尝试做某事 - 尽可能简单吗？我正在使用JQuery 1.3.1注册一个带有选择框id的点击处理程序。一切都很好，直到我使用Chrome和Safari测试，发现它不起作用。
I'm trying to do something when a user selects an option from a select box - As simple as can be right? I'm using JQuery 1.3.1 to register a click handler with the id of the select box. Everything was fine until I tested using Chrome and Safari and found it didn't work.
- Firefox 3.05 - 是
- IE 7.0.5730.13 - 是
- IE6Eolas - 是
- Sarafi 3.2.1 - 否
- Chrome 1.0.154.43 - 否
- Firefox 3.05 - YES
- I.E 7.0.5730.13 - YES
- IE6Eolas - YES
- Sarafi 3.2.1 - NO
- Chrome 1.0.154.43 - NO
请参阅以下代码：
<html>
<head>
<script language="javascript" type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js"></script>
<script language="javascript">
$(document).ready(function(){
$('#myoption').click(function() { alert('Select Dropdown was clicked: '+ $('#myoption').val()); });
});
</script>
</head>
<body>
<select id="myoption">
<option value="A">A</option>
<option value="B">B</option>
</select>
</body>
</html>
任何人都知道我应该为此工作做些什么？警报最终会被触发，但只有在双击选择框后？
Anyone know what I should be doing for this to work? The alert does eventually get triggered but only after double-clicking the select box?
推荐答案
我发现了我的问题。对于选择框，您需要为更改事件而不是单击事件注册处理程序。很奇怪Firefox和IE使用click事件。
I found my problem. For Select boxes, you need to register a handler for a "change" event rather than a "click" event. It's strange that Firefox and IE work with the click event.
总之，以下代码适用于所有浏览器：
To sum up, the following code works across all browsers:
<html>
<head>
<script language="javascript" type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js"></script>
<script language="javascript">
$(document).ready(function(){
$('#myoption').change(function() { alert('Select Dropdown was clicked: '+ $('#myoption').val()); });
});
</script>
</head>
<body>
<select id="myoption">
<option value="A">A</option>
<option value="B">B</option>
</select>
</body>
</html>
