Title: Submit button gives JavaScript error Last modified: September 26, 2023 --- # Submit button gives JavaScript error * Resolved [Noah Hearle](https://wordpress.org/support/users/designextreme/) * (@designextreme) * [2 years, 8 months ago](https://wordpress.org/support/topic/submit-button-gives-javascript-error/) * There is an error in the JavaScript when a submit `button` HTML tag is used. This occurs at the point a file upload is completed and the submit button switches from disabled to not disabled. * This JavaScript/jQuery should refer to either the first submit button or input, rather than just the (old style) input: * ```wp-block-code form.querySelector('input[type="submit"]').removeAttribute('disabled'); ``` * You can alter this to be something like this for wider support: * ```wp-block-code form.querySelector('button[type="submit"],input[type="submit"]').removeAttribute('disabled'); ``` * I haven’t checked elsewhere in the script, but further references to the submit button may need to be altered. - This topic was modified 2 years, 8 months ago by [Noah Hearle](https://wordpress.org/support/users/designextreme/).

One issue relating to the submit event that has caused quite a few problems – duplicate submissions. I wrote my own JavaScript code to prevent this. * I did notice this as a _premium_ feature, yet this is really something that would make this plugin/extension a lot more reliable for all users. I think it will just make things better for everyone if this was a standard feature. * Thread Starter [Noah Hearle](https://wordpress.org/support/users/designextreme/) * (@designextreme) * [2 years, 5 months ago](https://wordpress.org/support/topic/submit-button-gives-javascript-error/#post-17313425) * [@glenwpcoder](https://wordpress.org/support/users/glenwpcoder/) I have this error returning and it’s breaking other things: * _Uncaught TypeError: form.querySelector(…) is null_ * Location: ./assets/js/codedropz-uploader-min.js – 512:34 * The button is not a CF7 shortcode button, rather it is: * ```wp-block-code ``` * Plugin Author [Glen Don Mongaya](https://wordpress.org/support/users/glenwpcoder/) * (@glenwpcoder) * [2 years, 5 months ago](https://wordpress.org/support/topic/submit-button-gives-javascript-error/#post-17313993) * Thanks [@designextreme](https://wordpress.org/support/users/designextreme/) I’ll add or update the code to support submit and button tag. * I will release a new version today. * Plugin Author [Glen Don Mongaya](https://wordpress.org/support/users/glenwpcoder/) * (@glenwpcoder) * [2 years, 5 months ago](https://wordpress.org/support/topic/submit-button-gives-javascript-error/#post-17319368) * I just released a new version, please update and let me know if you still see an error. * Thread Starter [Noah Hearle](https://wordpress.org/support/users/designextreme/) * (@designextreme) * [2 years, 5 months ago](https://wordpress.org/support/topic/submit-button-gives-javascript-error/#post-17321402) * Thanks for sorting this [@glenwpcoder](https://wordpress.org/support/users/glenwpcoder/).
