jQuery select first x items of specific class
I have written a little jQuery function call .getRange() which returns a specific number of DOM elements against a jQuery selector (ie elements based on a specified class or id). It uses the jQuery.get() function and is basically an extension of that but allows for a range of elements to be returned.
Firstly, you should know to get the first and last elements like so:
var firstSpan = $('span.class:first'), lastSpan = $('span.class:last');
To get all the elements that match a specified class like so:
var allSpans = $('span.class').get();
or the nth element like so:
var firstSpan = $('span.class').get(0), secondSpan = $('span.class').get(1); //etc...
But how to get say the first 10 elements or elements 10-20?
It would be nice to go something like:
var mySpans = $('span.class').get(0,10);
Unfortunately, the .get() function doesn’t allow for a range to be passed, but just a single index.
So here is my attempt to use the jQuery .get() function to include a range of elements.
//function that gets a range of dom elements against a jQuery selector
//returns an array of dom elements
$.fn.getRange = function(start,end)
var elems = ;
for ( var i = start; i
It works this way, but i’m thinking it’s not an optimal solution so does anyone know of a better way to achieve this?
