Javascript replace string characters

Question

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

function doValidate()
{
var valid = true;

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

return valid;   
}

Why do you escape the comma? It has no special meaning in a regex. — ThiefMaster

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

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

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

Works fine for me, in both Firebug and the Node.JS console.

I think /[$,]/g would be better
