title: JavaScript custom button in Salesforce
body: <p>I created one custom button on the standard layout in Salesfoce which calls the apex code to call the java webservice. Now the problem is once the user clicks on the button I should disable the button or I should blur the screen until I process the request. How do I achieve this functionality with JavaScript?Any samples would be appreciated.</p>
