Help with Javascript RegExp

mpmcleod

I am having some problems with making RegExp work in both FF and IE. Specifically it has to do with the /.

In FF the following works fine:

replaceText = new RegExp(">save photo</a>\\s*\\|");
if ( replaceText.test(document.body.innerHTML) == true) {

}

but it doesn't work in IE nor in Opera.

I have tried escaping the / by using 1,2 and 3 \ but none works.

What I am trying to do is shown here:

Currently I have a second routine that is called which checks '>save photo<' and replaces just that text for IE and Opera.

thanks for any help or ideas.

ok, i think the problem is that you're not escaping the /

replaceText = new RegExp(">save photo<\\/a>\\s*\\|");

Personally, I don't like this RegExp syntax since u need to use double \.

The alternative way is...

replaceText = />save photo<\/a>\s*\|/

Hope this helps,

David

Found the problem still don't understand it. <img src="https://us.v-cdn.net/6029383/emoji/headscratch.gif&quot; border="0" alt="" >
IE/ Opera both REQUIRE the /i flag even though the match is lowercase.
while FF is smart enough to know it is not needed.

replaceText = new RegExp(">save photo</a>\\s*\\|","i");
or
replaceText = />save photo<\/a>\s*\|/i;

works in both while leaving off the ignore case flag breaks it in IE/Opera....

Thanks for the help.

Edit: The first part of the code is wrong. Dgrin keeps editing it and removing the a tag. Even wrapped with code tags the tag still gets removed.
