Question

Trying to a add target=”_blank” to all tags using javascript in a string.

Why does this work:

var editdescription = itemdescription.replace(new RegExp("All","g"),"Every");

But not this?

var editdescription = itemdescription.replace(new RegExp("<a","g"),"<a target="_blank"");

Answer 1

You’ve nested your double quotes incorrectly. Instead of

"<a target="_blank""

try escaping the double quotes:

"<a target=\"_blank\""

The way you wrote it was treated as two separate strings, "<a target=" and "" with _blank in between.

And as stated so many times before, preferably don’t parse HTML with regex.
