Uncaught Error: Invalid jQuery Selector

[realtekParticipant]

Hi,

I seem to suddenly be getting this error:

Uncaught Error: Invalid jQuery Selector - #jqxgrid .jqx-grid-cell! Please, check whether the used ID or CSS Class name is correct.

However #jqxgrid *does* exist on the page and I can’t seem to get to the bottom of it.

Could anyone point me in the correct direction please?

Thanks!

Hi realtek,

The Exception is thrown if the element does not exist on your page or does not exist at least when you try to use it. We check whether you try to use a widget from Invalid Selector i.e when there’s no such HTML Element in the DOM and we throw that exception on purpose to remind you to check your code for errors.

Hi Peter,

I am getting the same error but it happens even before we instantiate the grid (error is thrown when script is included as a RequireJS dependency). This is happening only in IE8 browser, other browsers are fine. It is not mentioning the name of selector in the message, so the error message is “Invalid Selector! Please, check whether the used ID or CSS Class name is correct.”

Any ideas?

Hi Nadeem Ullah,

The error means that you use Invalid jQuery Selector. If you use Correct ID or CSS Class for your jQuery Selectors, no error will be raised.

I found out the issue and yes, the element was not yet loaded because there was some issue in HTML syntax and IE8 is strict about it and it was not rendering the html at all. Corrected the syntax and the error was gone.

But there is another issue with JQX grid on IE8. I posted details to another post here.
