(NS_ERROR_FAILURE) Mozilla Browser

Question

I added an event handler to handle a mousedown event in firefox but I get a NS_error failure message when this event is encountered, the error message is displayed on firefox but chrome handles the event properly.

Here is the section of code

document.getElementById("fancybox-close")
.addEventListener("mousedown", function () {
    c.video.currentTime = "00:00";
    document.getElementById("playr_video_curpos_" + c.video_id).innerHTML = c.parseTimeCode(c.video.currentTime);
}, false); 

I attached the event listener to a close button on the video player, so when you click the close button the video is to be reset to 00:00 (Note: c = this ).

As said earlier this works on chrome but on firefox I get this error message

NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMHTMLVideoElement.currentTime]

Any idea why I get this message?

Answer 1

The currentTime attribute takes a number, not a string. In this case, Chrome must do type coercion, while Firefox does not. For example:

c.video.currentTime = 0.0; // Seek to zero seconds
