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 "

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((/\b(2)\b/g).test(lookup));
