删除javascript中的换行符

Question

I haven't found a solution yet in StackOverlfow to my problem.

I'm using nl2br() in PHP to insert linebreaks <br> instead of when storing a message on the database. The thing is I want to have a preview of that message that has no linebreaks. HOw do I remove the linebreaks <br> ?

I have tried text.replace('<br>', '');

"Hi guys!"
<br>
<br>
"How are you?"

Should be

"Hi guys! guys how are you?"

Answer 1

Could you post the exact code that you've tried and doesn't work?? This works fine:

<script type="text/javascript">
    var str = "Hi guys!<br><br>How are you?";
    str = str.replace(/<br>/g, " ");
    alert(str); // Gives "Hi guys!  How are you?" (Double spaced, due to 2 <br>'s being replaced)
    str = str.replace(/\s\s+/g, " ");
    alert(str); // Correct! "Hi guys! How are you?"
</script>

text.replace('<br>', ''); isn't a global replacement.
