Capture URL parameters and use on links

Anonymous · ‎08-27-2014

Hi. I have some landing pages that cannot have forms on them... but they link to other pages with Marketo forms. (It has to be that way, long story.)

On those landing pages, I would like to capture utm parameters from the URL and put it into the links that are on that page.

Is there a way to grab those parameters from the URL and put them into the links on the page?

Ah! I got one of my programmers involved, and he devised a bit of code that puts any URL parameters onto every link on the page.

So say "Thanks, Tad" when you use this. Just place it in the "custom meta tags" on a landing page.

//Written by Tad from ExploreLearning

if (document.location.search.length) {

jQuery.extend({

getQueryParameters : function(str) {

return (str || document.location.search).replace(/(^\?)/,'').split("&").map(function(n){return n = n.split("="),this[n[0]] = n[1],this}.bind({}))[0];

}

});

$( document ).ready(function() {

// get qs vars as obj

var qs = $.getQueryParameters();

//loop all links

$('a').each(function() {

//get href

var hrefParts = $(this).attr('href').split('?');

//get copy of qs obj

var docQS = qs;

//get href qs vars as obj

var aQS = $.getQueryParameters(hrefParts[1]);

//merge together qs objs

$.extend(docQS, aQS);

//create new href string

var newHref = hrefParts[0] + '?' + jQuery.param(docQS);

//update link href

$(this).attr('href', newHref);

});

}

</script>
