Get jQuery and jQuery UI versions using Developer Tools Console

Simply paste the following into the Developer Tools Console and hit Enter. An alert box will pop up with the version information:


var jQueryVersions = '';
if($().jquery){
    // jQuery is loaded
    jQueryVersions += 'jQuery = ' + jQuery.fn.jquery + '\n';
}else {
    // jQuery is not loaded
    jQueryVersions += 'No jQuery\n';
}if($.ui){
    // jQuery UI is loaded
    jQueryVersions += 'jQuery UI = ' + jQuery.ui.version;
}else {
    // jQuery UI is not loaded
    jQueryVersions += 'No jQuery UI';
}
alert(jQueryVersions);
