Prevent double submit

Question

I have a submit button:

<div class="submitForm"> <input type="submit" id="submit" value="SAVE" class="greyishBtn" onclick ="if(!DW_CheckIfImagesInBuffer()) {return confirm('No images'); }else{ btnUpload_onclick(2)}"/> </div>

I'm tryng to to prevent submit form twice disabling button in this way:

else{ btnUpload_onclick(2) this.disabled=true; this.value='Please Wait...';}

Button when submit change to Please Wait, but form is not submitted.

Any help?

This may be obvious, but is the button actually inside a form? — Evan Davis

The problem is ; in the else statement

btnUpload_onclick(2) this.disabled=true; this.value='Please Wait...'; // ^ Here ^ Like this

Change to

btnUpload_onclick(2); this.disabled=true; this.value='Please Wait...';
