Calling multiple JavaScript functions on a button click

Question

How to call multiple functions on button click event?

Here is my button,

Answer 1

Because you're returning from the first method call, the second doesn't execute.

Try something like

OnClientClick="var b = validateView();ShowDiv1(); return b"

or reverse the situation,

OnClientClick="ShowDiv1();return validateView();"

or if there is a dependency of div1 on the validation routine.

OnClientClick="var b = validateView(); if (b) ShowDiv1(); return b"

What might be best is to encapsulate multiple inline statements into a mini function like so, to simplify the call:

// change logic to suit taste
function clicked()  {
    var b = validateView(); 
    if (b) 
        ShowDiv1()
    return b;
}

and then

OnClientClick="return clicked();"
