Anchor's Download Property Is Not Working On Some Pages (Gmail)?

I want to insert this HTML element in some pages:

Here's the function:

var downloadDataURI = function($, options) {
    if(!options)
        return;
    $.isPlainObject(options) || (options = {data: options});
    if(!$.browser.webkit) 
        window.location = options.data;
    options.filename || (options.filename = "download." + options.data.split(",")[0].split(";")[0].substring(5).split("/")[1]);
    options.url || (options.url = "http://download-data-uri.appspot.com/");
    $('<form method="post" action="'+options.url+'" style="display:none"><input type="hidden" name="filename" value="'+options.filename+'"/><input type="hidden" name="data" value="'+options.data+'"/></form>').submit().remove();
}

And here's how to call it:

downloadDataURI($, {filename: "test.csv",data:"data:application/csv;charset=utf-8,Col1%2CCol2%2CCol3%0AVal1%2CVal2%2CVal3%0AVal11%2CVal22%2CVal33%0AVal111%2CVal222%2CVal333"});

Solution 2:

In Chrome with JQuery, I try this approach:

var dataUri = "data:application/csv;charset=utf-8,Col1%2CCol2%2CCol3%0AVal1%2CVal2%2CVal3%0AVal11%2CVal22%2CVal33%0AVal111%2CVal222%2CVal333"
var filename = "somedata.csv"

$("<a download='" + filename + "' href='" + dataUri + "'></a>")[0].click();

I created a temp link and trigger click event on it. but not sure if other browsers work or not.
