Steps to choose a div element from an Ajax Response utilizing Prototype JS

I attempted to use the code below, but unfortunately I have not been able to achieve success yet.

var myAjax = new Ajax.Request(
    url,
    {
        method: 'post',
        onException: function (xhr, e)
        {
            alert('An exception occurred: ' + e);
        },
        onComplete: function (xhr)
        {
            var myHtml = xhr.responseText;

            // alert(myHtml);

            var myContent = $(myHtml).select("div#product-options-wrapper");

            alert(myContent);
        }
 });

If anybody could provide assistance, it would be greatly appreciated. Thank you in advance.

As mentioned by others, the HTML is treated as a string. To extract the elements you need, consider placing it within a container div. Use the select() method to get an array of elements matching the selector. If you specifically want a single <div>, utilize the down() method to retrieve the first one.

var myAjax = new Ajax.Request(
    url,
    {
        method: 'post',
        onException: function (xhr, e)
        {
            alert('Exception : ' + e);
        },
        onComplete: function (xhr)
        {
            var myHtml = xhr.responseText;

            // alert(myHtml);

            var myContent = new Element('div').update(myHtml);

            myContent = myContent.down("div#product-options-wrapper");

            alert(myContent);
        }
 });

myHtml remains as a string object ... To make it usable, you must include it in the DOM and from there you can easily select whatever you need.

var myAjax = new Ajax.Request(
url,
{
    method: 'post',
    onException: function (xhr, e)
    {
        alert('An exception occurred : ' + e);
    },
    onComplete: function (xhr)
    {
        var myHtml = xhr.responseText;

        // alert(myHtml);

        /***** Attach your html content to any existing container within the document *****/

        var myContent = $(myHtml).select("div#product-options-wrapper");

        alert(myContent);
    }

});
