Disable commandButton after first click to prevent double submission

Hi Himanshu,

I suggest to use a JavaScript function called by button's onclick event, which internally calls an actionFunction to post the form, disables the buttons on the page and then returns false on the button. And oncomplete event will re-enable the button when the form has been (ajax) posted and returns a result to the page.

Thanks

You can use javascript for disabling button after the click. Here is a piece of code for that.

<apex:commandButton value="Submit" id="Submit" onClick="SubmitOnClick(this);" />

<apex:actionFunction name="doSubmit" action="{!Submit}" />
</apex:form>

<script language="Javascript">
function SubmitOnClick (objSubmitBtn) {
objSubmitBtn.disabled = true;
objSubmitBtn.value = 'Submitting...';
doSubmit();
}
</script>
