I'm having trouble writing the HTML below to the page after an asynchronous get request. The HTML is provided by a 3rd party charting service, so I can't modify it myself, other than when I get the response after the $.get().

I asked the following question a while ago: Why is t开发者_如何学Chis HTML causing the page to go blank. The answer was:

"document.write after the page has fully rendered ... will create a new document"

As such, would it be possible for me to replace the document.writeln() function with a jQuery function which will include the HTML in thd DOM? If so, what is it I need to do?

is it a case of find and replace? Or will it even work? Is there another way to solve this issue?

For reference, this is the code that does the get:

$.get(url, {}, function (result) {

    $('#FactsheetTabs .tab_container').fadeOut(100, function () {
        $('#tabs')
            .append(result) // this fails in FireFox & chrome, but not IE... why?!
            .fadeIn(100);
    });
}, 'html');

If I edit the response to comment out the document.writeln() code like the following, it works:

$.get(url, {}, function (result) {

    $('#FactsheetTabs .tab_container').fadeOut(100, function () {
        result = result.replace("document.writeln", "//document.writeln");
        result = result.replace("document.writeln", "//document.writeln");
        $('#tabs')
            .append(result) // this works now...
            .fadeIn(100);
    });
}, 'html');


You can override the document.writeln() function with one of your own that will safely append the html to the DOM without breaking it. For example:

document.writeln = function (html) {
    $(document.body).append(html);
}

The other option is close to your replace method but, instead of adding comment delimiters, replace document.write with your own method:

result = result.replace(/document\.writeln/g, "$(document.body).append");
