Answer 1

Create a global variable and then set the value of global variable to local variable, like this
As document ready global variable has not any value, but when you click on document it get the value and have value of local variable and then you can call it anywhere

 var globalvariable = null; $(document).ready(function(){ console.log(globalvariable); }); $(document).click(function(){ var localvariable = 20; globalvariable = localvariable; console.log(globalvariable); });
