JQuery : Calling a function inside Jquery(document) block
Problem :
Saw this error message in the browser's console while attempting to call a function inside JQuery(document) section resulted in this error message :
Uncaught ReferenceError: callFunctionInsideJquery is not defined
So, how does one call a function inside JQuery(document) section ?
Solution :
Enable the function be called globally. Add the JQuery window
reserve word in front of the function you want to make it accessible globally. See :
<script>
function pressButton() {
callFunctionInsideJquery("Yes, I'm here!");
}
jQuery(document).ready(function($) {
// private function inside JQuery(document) block
function callFunctionInsideJquery(msg) {
$('#error').html(msg).hide().fadeIn(800);
}
}
);
</script>
to
<script>
function pressButton() {
callFunctionInsideJquery("Yes, I'm here!");
}
jQuery(document).ready(function($) {
// public function inside JQuery(document) block accessible globally with window
window.callFunctionInsideJquery = function(msg) {
$('#error').html(msg).hide().fadeIn(800);
}
}
);
</script>
