var name = "myName";
function test() {
document.write(name);
}
var testcheck= test();
document.write(testcheck);
This returns " myNameundefiend " that is the value+undefined why is that happening ?
You're not returning a value from your test
function, making the testcheck
variable undefined
.
The test()
call first writes the name to the document, then document.write(testcheck);
adds undefined
behind that.
You'll need to return
name
from the function:
function test() {
document.write(name);
return name;
}
There's no need to document.write
twice. Either only keep it in the function, or remove it from the function and use document.write(testcheck);
.
