In Pset8 I chose to create a shorturl for the extra feature. I have returned the shorturl from a php script as a string. This should then get displayed for the user in a div. I can console.log the value of the variable shorturl, but when I try to append the url to the div, it is blank. Is this related to "escaping" or a javascript equivalent of htmlspecialchars? Thanks

function showInfo(marker, content, place)
    var placeparams = { id : place.postal_code};
    var shorturl = [];

    //$.get("shorten.php", placeparams)

        .done(function(data) {
            shorturl = data;

            //shorturl = data;
        .fail(function(errorThrown) {
            // log error to browser's console

    div = "<div id='info'>";
    if (typeof(content) === "undefined")
        // http://www.ajaxload.info/
        div += "<img alt='loading' src='img/ajax-loader.gif'/>";
        div += "<h3>What's up in " + marker.labelContent + "?</h3>" + "<h4>Copy shorturl: " + shorturl.toString() + "</h4>";
        div += content;

    // end div
    div += "</div>"; });
  • OK..so I have changed the code up to use a callback which should update the div by id, and cannot figure out how to pass the result to the innerhtml. – Celebrity Butter Churner Oct 6 '15 at 4:20
  • What value do you get in JavaScript Console for shorturl? – Mustaghees Oct 10 '15 at 4:03
  • I have since changed my shorten.php around so that it just returns the url as a string. That console.log(shorturl) displays something like "goo.gl/foo" I suppose I should try to look at the actual value of shorturl via the dev tools. I will look up how to do that in chrome. – Celebrity Butter Churner Oct 14 '15 at 3:39
  • I rewrote most of this and added a button to initiate the shorten. This made me realize that the button is receiving shorturl before the .done has fired off. So I may change it to get the shorturl as soon as the user has opened the info window, then create the button only after .done. – Celebrity Butter Churner Oct 14 '15 at 5:50

I was updating the shorturl variable in .done, but the rest of the code had already executed. This is actually a fairly basic error now that I've figured it out. I added $.('#shorturl-div').html(shorturl); inside of .done. Now it waits until it has the shorturl to attempt to update it in the dom.
