version added: 1.0jQuery('[attribute^=value]')

- 一个属性名.
- value
- 一个属性值,引号是可选的。
描述: 选择指定属性是以给定字符串开始的元素
This selector can be useful for identifying elements in pages produced by server-side frameworks that produce HTML with systematic element IDs. However it will be slower than using a class selector so leverage classes, if you can, to group like elements.
Example:
Finds all inputs with an attribute name that starts with 'news' and puts text in them.
<!DOCTYPE html>
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.min.js"></script>
</head>
<body>
<input name="newsletter" />
<input name="milkman" />
<input name="newsboy" />
<script>$("input[name^='news']").val("news here!");</script>
</body>
</html>
