Question

I want to do the following:

if (htmlEdit) {
    var dialogDiv = $('#commonDialog');
} else {
    var dialogDiv = $('#commonDialog2');
} 

But if I do that I think dialogDiv will not be available outside of the if-else. How can I declare it so I will be able to use it in another place after the if-else?

Answer 1

you can do like this,

 var dialogDiv;
if (htmlEdit) {
    dialogDiv = $('#commonDialog');
} else {
    dialogDiv = $('#commonDialog2');
}
