attributeStartsWith selector

Description: Selects elements that have the specified attribute with a value beginning exactly with a given string.

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

attribute: An attribute name.

value: An attribute value. Can be either a valid identifier or a quoted string.

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 lang="en">
<head>
  <meta charset="utf-8">
  <title>attributeStartsWith demo</title>
  <script src="https://code.jquery.com/jquery-4.0.0.js"></script>
</head>
<body>
<input name="newsletter">
<input name="milkman">
<input name="newsboy">
<script>
$( "input[name^='news']" ).val( "news here!" );
</script>
</body>
</html>
