Autopopulate a SharePoint Form from URL (with SPUtility.js)

SPUtility.js is a library used to get/set SharePoint’s form fields. We can also use it autopopulate a Newform/Editform based on some URL parameters which are passed to the page!

Our page’s URL could be something like: /Lists/ProjectTasks/NewForm.aspx?projectID=523

I want to take the projectID URL parameter and autopopulate my Project ID field with this value. Then, we’ll make the field read only.

Here’s the code (updated 4/2/2014 to use jQuery version of SPUtility.js):

<script src="/subsite/Files/jquery-1.11.0.min.js"></script>
<script src="/subsite/Files/sputility.min.js"></script>
// url parsing from
var urlParams;
(window.onpopstate = function () {
    var match,
        pl     = /\+/g,  // Regex for replacing addition symbol with a space
        search = /([^&=]+)=?([^&]*)/g,
        decode = function (s) { return decodeURIComponent(s.replace(pl, " ")); },
        query  =;
    // fix for sharepoint 2013 URLs which use the hash
    if (query === '') {
        query = window.location.hash.substring(window.location.hash.indexOf('?'));
    query = query.substring(1);
    urlParams = {};
    while (match = search.exec(query))
       urlParams[decode(match[1])] = decode(match[2]);

// wait for the window to load
$(window).load(function () {
    try {
        var urlValue = urlParams['projectID'];
        SPUtility.GetSPField('Project ID').SetValue(urlValue).MakeReadOnly();
    } catch (ex) {

To install, you’d simply place the JavaScript above into a Content Editor Web Part on your NewForm.aspx or EditForm.aspx. Take a look at the SPUtility.js Installation page for detailed instructions.
