This is usually handed via XMLHttpRequest, usually abstracted via a library that irons out the differences between browsers (bigger libraries that do lots of other stuff include YUI and jQuery).

You could use jQuery, or another javascript library, but instead of thinking of populating the variable then continueing with the script in a linear way, you should think in terms of a callback once the value is retrieved, because it can take a variable amount of time to retrieve the data.

This event based architecture is a feature of javascript that is rare in other programming languages.

$.get('search.php?term=hello', function(data){
    alert(data)
});
