  1. Javascript created form submission to iframe opens new tab IE

    September 12, 2011 by Dave

    Well; of course, Internet Explorer invents its own rules and anyone trying to create a form with JavaScript and submit it to an iframe also created with JavaScript will know that this causes Internet Explorer to submit it to a new tab..

    Very annoying, But here is a solution.

    When you’re creating your iframe, don’t create it as a DOM element, create a wrapper for it and change its innerHTML.

    See below

    var a = document.createElement('div');
document.appendChild(a);
a.innerHTML = '<iframe name="targetMe" id="targetMe"></iframe>'

    Now your form can target that iFrame! Easy!

  2. C Fakepath fix

    September 1, 2011 by Dave

    So I’m sure any developers reading this have come across the Safari, IE7+ and Opera issue where an upload field is for whatever reason filled with C:\fakepath\filename GRR! How annoying!

    But below is a really simple fix!

        //get our form field
    var a = document.getElementById('myUploadField'),
        b = encodeURI(a.value),
        c = b.replace("C:%5Cfakepath%5C","");
    //We then listen for the value changing and
    //remove the C:\fakepath\ from it! easy!
    a.onchange = function () {
        this.value = c;
    }

    How easy was that!
