Hi I have a question in Javascript.

I need a alert msg with "Yes", "No" buttons. If it is possible, Can we have a sample code?

Thanks

A confirm box is often used if you want the user to verify or accept something.When a confirm box pops up, the user will have to click either "OK" or "Cancel" to proceed. If the user clicks "OK", the box returns true. If the user clicks "Cancel", the box returns false.
if(confirm("Are you sure to reload data?")){
    grid.reload();
}else{
    //to do nothing
}
