Here is an example of initializing a global variable in one jQuery function and using it in another function:
// Initialize global variable in function 1
var myVar;
$(document).ready(function() {
myVar = "Hello world";
});
// Use global variable in function 2
$(document).on("click", "#myButton", function() {
alert(myVar);
});
In this example, we initialize a global variable called myVar
in the $(document).ready()
function. This function sets myVar
to the string "Hello world".
Later in the code, we use the myVar
variable in a click event handler for a button with the ID myButton
. The click event handler function uses alert()
to display the value of myVar
.
Note that because myVar
is a global variable, it can be accessed and modified from any function in the script.
