I'm trying to write a regex which
does not allows a number to come before or after a number like.
I have ids like this
abcd-1
abcd-11
abcd-21
...
abcd-91
I can't figure out how to write a regex that
gives me the element that have only 1
I mean abcd-1 (having no digit before and after 1). I am doing something like this
$("[id$=1]")
which gives me all the the elements from abcd-1 to abcd-91. I just neeed abcd-1.
Can you please help?
There exists a regex filter to elements selectors that you need to append to jquery:
http://james.padolsey.com/javascript/regex-selector-for-jquery/
You can then use it as below:
// Select all elements with an ID starting a vowel:
$(':regex(id,^[aeiou])');
// Select all DIVs with classes that contain numbers:
$('div:regex(class,[0-9])');
// Select all SCRIPT tags with a SRC containing jQuery:
$('script:regex(src,jQuery)');
In your case the following shall match:
$(':regex(id,\w*-1)');
Or you can use filter with just jquery:
$('*').filter(function() {
return this.id.match(/\w*-1/);
}).click(function(){ //your click event code here });
You can't use a regex in a selector. (Not with just the base jQuery library, anyway.)
But you don't need regex to implement what you are describing. You are already using the "attribute ends with" selector, which finds all elements ending with the specified text without regard for what came before that text.
How about searching for ids ending in -1? As in:
$("[id$='-1']")
That will match the abcd-1 element you asked about, but not abcd-91.
abcd-1, which clearly does end in -1.
