functions in JavaScript

[uknowist]

I'm pretty new to programming and am doing an assignment where I need to be able to change a variable in a javascript programme. The global variable is already set but this has to be changed to whatever the user inputs via a window prompt. Where do I start?

Right, so start with your variable which has been set globally:

var varx = "value1";

Then create the function that asks input and shoves it in the variable:

function changeVar() {
varx = prompt("Text shown to the user","Default Value");
}

Then just run changeVar() whenever you need to change the variable.

For more information on JavaScript there are loads of tutorials on my website, see here: http://www.livescripts.net?tutorials/basjsindex.htm
