I already am doing a replace for the mas in an textbox. How would I replace if there is an "$" and a ma also in the same line?

function doValidate()
{
var valid = true;

document.likeItemSearchForm.sup.value = document.likeItemSearchForm.sup.value.replace(/\,/g,''); 

return valid;   
}

• 2 Why do you escape the ma? It has no special meaning in a regex. – ThiefMaster Commented Sep 26, 2011 at 13:37

Do you want to replace mas and dollar signs? Here's how:

"$foo, bar.".replace(/\$|,/g, "")

The regexp matches dollar signs or mas. The g flag tells it to match the entire string instead of stopping after the first match.
