Quick Check for Version of jQuery

September 3, 2009 by Annyce Davis Leave a Comment

A quick way to check for the running version of jQuery in your code:


if (jQuery.fn.jquery < '1.3.2')
console.log('yes');

jQuery each function

July 31, 2009 by Annyce Davis Leave a Comment

jQuery has done it again with a very succinct function to iterate over the values of a set and perform an action for each one. The each function is easy to use and keeps your code from being cluttered with many for loops.


var allAlts = new Array();
$('img').each(function(){
allAlts.push(this.alt);
});

These few lines of code will get the alt attribute of every image tag in your document and store it in an array.

Case Insensitive jQuery :contains Selector

June 26, 2009 by Annyce Davis Leave a Comment

This is useful because for some reason the :contains selector in jQuery is not case-insensitive. BTW the code below works with jQuery 1.3.


jQuery.expr[':'].contains = function(a,i,m){
return jQuery(a).text().toUpperCase()
.indexOf(m[3].toUpperCase())>=0;
};
