Disable the javascript button after it clicked once

Hi ,

I have written a javascript button to create a record on salesforce .when the user clicks once on the button the record is created .but he clicks again on the button another record is created.

I just dont want the user to click the button again and create a duplicate record.Is there any other way to disable the button after the user clicks once or else if the record is already created .he needs to be prompted  that  the record is already exixts.
  
{!requireScript("/soap/ajax/26.0/connection.js")} 

var req = new sforce.SObject("Candidate__c"); 
req.Id = "{!Candidate__c.Id}"; 
req.Job_Application__c="True"; 
req.Recruiting_Status__c="Possible Candidate" 
var aResult = sforce.connection.update([req]); 
if (aResult[0].getBoolean("success")) { 
console.log("Candidate Update Successful"); 
} 
var newJob = new sforce.SObject("Job_Application__c"); 
newJob.Candidate__c= "{!Candidate__c.Id}"; 
newJob.Position__c= "{!Candidate__c.PositionId__c}"; 
newJob.Status__c="open"; 

var cResult = sforce.connection.create([newJob]); 
if ( cResult[0].getBoolean( "success" ) ) 
{ 
alert("Candidate Created Sucessfully "); 
window.location.reload(); 
} 

else 
{ 
alert( cResult[0].errors.message); 
}

Hey Praveen,
you can use render operation and try to write some code for render function that once is created the button is hidden like that.
Thank You

Unfortunately we can't disable the button, I think best option would be keeping a confirm box before entering into the logic OR query for the record which you have inserted first time if the record exist just escape the logic and display an alert message

Another way you can acheive is chage record type of the record after clicking it and then remove that button in new wlayout. This way they wont see button after clicking once.
