How to disable the button???

Question

Hi, guys.
I searched the forum, but did not find anything about disabling the button. There are examples of disabling text areas... But when i tried to implement same technics to disable a button, it did not work.
I have a page with two regions items region and buttons region. When page opens i want to check if P1_TXT_BOX in items region is empty and if yes, disable button P1_CMD_DOTHIS in buttons region. And then onBlur for P1_TXT_BOX, if it is not empty - enable the button.
Pls, help...
Thnks.
Mike

Hi,
I have always struggled with buttons and javascript in APEX because of the way it generates the buttons (as a "button" not "submit").
A way round it would be to create the buttons using html then disabling the accept button:
<input type="submit" id="P1_DOWNLOAD" value="Download" onclick="swapButtonStatus();" />
<input type="submit" id="P1_ACCEPT" value="Acc" onclick="swapButtonStatus();" />
<script>
document.getElementById('P1_ACCEPT').disabled="true";
</script>
You just need to put them in the region footer or somewhere applicable.
And use the following javascript function in the HTML Header:
function swapButtonStatus()
var downloadButton = document.getElementById('P1_DOWNLOAD');
var acceptButton = document.getElementById('P1_ACCEPT');
if(acceptButton.disabled=="")
downloadButton.disabled="";
acceptButton.disabled="true";
//you can submit the button using: then create a process that
//runs when request=Accept
doSubmit('Accept');
else if(downloadButton.disabled=="")
acceptButton.disabled="";
downloadButton.disabled="true";
//you can submit the button using: then create a process that
//runs when request=Download
doSubmit('Download');
Hope this helps
