I am trying to use jQuery to loop through a list of elements that have the same classname & extract their values.
I have this..
function calculate() { // Fix jQuery conflicts jQuery.noConflict(); jQuery(document).ready(function(){ // Get all items with the calculate className var items = jQuery('.calculate'); }); } I was reading up on the each() function though got confused how to use it properly in this instance.

each(), which is used to iterate, exclusively, over a jQuery object. The $. each() function can be used to iterate over any collection, whether it is an object or an array. In the case of an array, the callback is passed an array index and a corresponding array value each time.
Answer: Use the jQuery each() Method You can simply use the jQuery each() method to loop through elements with the same class and perform some action based on the specific condition.
each() function, jQuery's foreach equivalent. jQuery's foreach equivalent can be very useful for many situations. These examples will get you started and teach you how you can loop through arrays, objects and all kinds of HTML elements.
forEach() , which uses the following syntax : myArray. forEach(function(value, key, myArray) { console. log(value); });
jQuery('.calculate').each(function() { var currentElement = $(this); var value = currentElement.val(); // if it is an input/select/textarea field // TODO: do something with the value }); and if you wanted to get its index in the collection:
jQuery('.calculate').each(function(index, currentElement) { ... }); Reference: .each() and .val() functions.
