Well, a number by definition can't have spaces in it. So if there ARE
spaces, then it's a string, and can be treated as such.
Alternately I suppose you could try multiplying the value by 1 and see what
you get.

Totally off the top of my head (and therefore totally untested, but it
should be good)
var EnteredValue = $.trim($(#SearchText).val());
var TestValue = EnteredValue.replace( , );
if (isNaN(TestValue)) {
return EnteredValue; // User must have entered a keyword
}
else {
return
okay..so how can check if the string only contains numbers?
im quite new to jquery..would i need to use reg ex?

Takes out user entered spaces
var TestValue = EnteredValue.replace( , );
Checks if the remaining value is numeric
isNaN(TestValue)
And this method doesn't really need jQuery (nor would i see why it
would have to)
hi thanks for the quick code but this does not seem to evaluate if i
enter a number.
see code below
$(#searchForm input.submitBtn).click(function(e){
var EnteredValue = $.trim($(#keywords).val());
var TestValue = EnteredValue.replace( , );
Here is some working code

and just to note on your code, you have:
alert(is a number)
*after* the return TestValue line... that would never ever fire
thanks so much your a star...i have much to learn... and off i go
to do it!!!
