Why can't I assign a variable inside a function in Javascript?
Question by Clark
Very new to JS here. When I write PHP I have no problem assigning variables inside a function, but inside a JavaScript function it doesn’t work. Why?
example:
function hello() {
var animal = 'Dog';
document.write(animal);
}
Answer by DVK
Are you calling the hello() function anywhere? If not, you will not execute the contents of the function and thus, no write will happen.
Answer by Starx
put this snippet inside your function to check if your function is being called
alert('snippet');
If a message box appears, your code should work, but if it does not then the function is not being executed, post some html coding also.
