Jquery find all ids starting with a string?

Question

Just wondered how I would search for all the ids starting with \"content_\" in the whole page and also a way to only find them in a named div called \"extra_content\". Once

Answer 1

Use the attribute-starts-with selector:

$('[id^="content_"]').hide();

To limit the search to elements within extra_content:

$('#extra_content [id^="content_"]').hide();
