jQuery selector regular expressions

Question

I am after documentation on using wildcard or regular expressions (not sure on the exact terminology) with a jQuery selector.

I have looked for this myself but have

Answer 1

If you just want to select elements that contain given string then you can use following selector:

$(':contains("search string")')

Answer 2

ids and classes are still attributes, so you can apply a regexp attribute filter to them if you select accordingly. Read more here: http://rosshawkins.net/archive/2011/10/14/jquery-wildcard-selectors-some-simple-examples.aspx

Answer 3

var test = $('#id').attr('value').match(/[^a-z0-9 ]+/);

Here you go!

Answer 4

These can be helpful.

If you're finding by Contains then it'll be like this

    $("input[id*='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you're finding by Starts With then it'll be like this

    $("input[id^='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you're finding by Ends With then it'll be like this

     $("input[id$='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which id is not a given string

    $("input[id!='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which name contains a given word, delimited by spaces

     $("input[name~='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });

If you want to select elements which id is equal to a given string or starting with that string followed by a hyphen

     $("input[id|='DiscountType']").each(function (i, el) {
         //It'll be an array of elements
     });
