Attribute Starts With Selector [name^=value]

attributeStartsWith selector

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

  • attribute
    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>
