Question

Ajax form submit usability. when i submit the form i wanna diable the form to be submited till the previous submission happens. can i do this by just disabling the input or text area or should i disable the submit button too ?

Answer 1

You can disable form-submission by letting its onsubmit-handler return false:

<form onsubmit="return false">...

Of course you would have a javascript-function which decides whether to submit or not:

<form onsubmit="return myDecisionFunction()">...

The decision-function in your case could look like this:

var submissionEnabled = true;
function myDecisionFunction() {
   if (submissionEnabled) {
       submissionEnabled = false;
       return true;
   } else {
       return false;
   }
}

And after the ajax-response came in, you enable it again:

submissionEnabled = true;
