regex - How can I match a whole word in JavaScript?

Question

I am trying to search a single whole word through a textbox. Say I search "me", I should find all occurrences of the word "me" in the text, but not "memmm" per say.

I am using JavaScript's search('my regex expression') to perform the current search (with no success).

After several proposals to use the switches (which don't seem to work) I am posting a revised explanation of my problem:

For some reason this doesn't seem to do the trick. Assume the following JavaScript search text:

var lookup = '





2    PC Games        



';
lookup  = lookup.trim() ;
alert(lookup );

var tttt = 'tttt';
alert((/(lookup)/g).test(2));

Moving lines is essential

Answer 1

To use a dynamic regular expression see my updated code:

new RegExp("\b" + lookup + "\b").test(textbox.value)

Your specific example is backwards:

alert((/(2)/g).test(lookup));
