Accessing a Server-side Component Context from outside of a Client-side Component Context

Create a Server-side script with the following code:

function setName(myName){
  fields.name.value = myName;
}

Add this script to the Client Callable Functions of myComponent. 

Add the sweetalert.js library to myComponent -

<script src="https://unpkg.com/sweetalert/dist/sweetalert.min.js"></script>

.

Add a jQuery click event handler to the Button Control with the following code:

Swal("Hello").then(function(){
  $eb.executeFunction("setName", "Brian", true, false, null);
})

Create a Form myForm and add myComponent to it.

Run myForm and click the Alert button. Then click the OK button to dismiss the sweetalert.

The name field will not have been populated because $eb.executeFunction() did not execute from within the Client-side Component Context.

Modify the jQuery click event handler on the Button Control:

var pfx = $eb.getComponentPrefix();
Swal("Hello").then(function(){
  $eb.executeFunction("setName", "Brian", true, false, null, pfx);
});
