Question

Consider this code:

function callme() {
    alert('call');
}

$(function(){ 
    var iframe = $('<iframe />').attr('src', 'b.php').appendTo('body'); 
    //call 'callme' function from parent
});

I don’t want to edit b.php.
Is there any way I can call the parent ‘callme’ function using just javascript in the parent file?

Answer 1

Not sure about the part “I don’t want to edit b.php“. Your question is asking about how to call the parent function from an iframe and b.php is in the iframe. How can you make it call the parent callme() without modifying b.php?

From b.php you can call

parent.callme();

Or is your question, how can I call callme() after b.php finishes loading?
