正则表达式不能在“ JavaScript字符串内”工作

Question

I'm trying to replace all mentions of [b] in a text string and replace it with <b> . The problem with what I'm using below this that it's replace every [b] on the page, and I only want it to change the [b]'s within the text string ("text") that I'm sending in.

Taking out the 'g' for global in the regex doesn't work very well because it then doesn't replace them all...

text = $("#input").val();

text = text.replace(new RegExp('(^|\\s|>)\\[b](\\S.*?\\S)\\[/b]($|\\s|<)', 'gim') , '$1<strong>$2</strong>$3');

any ideas? Thanks

I'm not exactly sure what the problem is because the question is a bit unclear. Are you trying to replace the content within the textarea with the new html tags?

The following code is currently working for me in production:

text = $("#contract_body").val();  // strore the current contents
text = text.replace(/\[b\](.*?)\[\/b\]/gim, "<strong>$1</strong>");  // replace bbcode with html tags
$("#contract_body").val(text);  // update the textarea with the new string contents

I hope that helps.
