Replacing Multiple Line Breaks

[ldsmike88]

I have a line of code that looks something like this:

 

var myTextareaValue = textareaValue.replace('\n','<br/ >');

 

That works fine when I only have one line break at a time. But if I have multiple line breaks it only puts one <br/ > tag in instead of two or three. How can I make it so it will put in the right amount of break tags. Thanks!

(I know my break tags in this forum aren't formatted correctly, but if they are they actuly are break tags and you can't see them.)

change

var myTextareaValue = textareaValue.replace('\n','<br/ >');

 

to

 

var myTextareaValue = myTextareaValue.replace(/\n/g, /<b r>/ );

 

 

The g switch makes the changes global.

I'm not certain if you can escape the forward slash in the <b r /> replacement section

but if you can it'll probably look like /<br \/>/

I added a space in the br to stop the line from breaking

[ldsmike88]

so is the first term in the replace function 'forwardslash backslash n forwardslash g'? Or did you add one of those slashes to prevent it from executing something?

[ldsmike88]

That didn't do anything different. With '\n' and with '/\n/g' it only inserted one break. For example.

 

If I put in

here is

 

some text

 

it puts out

here is

some text

Well the problem was that it only fixed the first line break. I got it to work now. Thanks!

 

This is the code I had to use:

while(this.value.match('<br />') == '<br />'){
  this.value = this.value.replace('<br />','\n');
}

You're simply missing the /g modifier -- you don't need to do a while you.

[ldsmike88]

I don't think I even know what the /g modifier is or what it does.

[fenway]

It replaces all matches of your regex... it's a global modifier.

this.value = this.value.replace(/<br \/>/g,'\n');

[ldsmike88]

So the initial slash is like the first quote and the /g is like the last quote?

You should read up on JS regexes, but yes.
