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.
