Writeln Img Src To Submit Data To External System - Firefox And IE Hanging

I have been scouring the depths of the web to find a solution to a problem I'm having. I'm relatively new to Javascript so forgive me. Upon clicking the next button on my checkout

Solution 1:

I think the behavior caused by the way how do you want to write an HTML element into a page. For your propose I think I got a better way:

So the first change is to add an img emelent that is not visible:

<img src="" id="hiddenImg" width="1" height="1" border="0" alt="" style="visibility:hidden">
<!-- You can also use display:none; -->

The second one is to change your Javascript:

function AddContact()
{
    ... lines skipped ...

    var targetUrlStr = "";
    if (document.getElementById('idINVOICEPRIVACY').checked == false)
    {
     targetUrlStr = 'https://app.bronto.com/public/<url cut here>';
    } else if (document.getElementById('idINVOICEPRIVACY').checked == true) {
     targetUrlStr = 'https://app.bronto.com/public/<url cut here>';
    }
    document.getElementById("hiddenImg").src = targetUrlStr;
    return true;
 }

Hope it will help.
