Get ContentTypeId In NewForm.aspx URL QueryString

Question

I've been trying to access the ContentTypeId in the NewForm.aspx querystring. Knowing that will allow me to set up conditional statements to display information specific to a Content Type. My question:

Does anyone have some code to share that demonstrates, with jQuery or javascript, how to get the value of ContentTypeId parameter in the querystring?

Thanks in advance!

Answer 1

Or, without jQuery:

function querySt(stKey) {
    stQString = window.location.search.substring(1);
    arKeyValues = stQString.split("&");
    for (i = 0; i < arKeyValues.length; i++) {
        arPairs = arKeyValues[i].split("=");
        if (arPairs[0] == stKey) {
            return arPairs[1];
        }
    }
};

var contentTypeId = querySt("ContentTypeId");

With the following jQuery extension (see here), you could use the following code to get your ContentTypeId :

var contentTypeId = $.query.get('ContentTypeId');
