Javascript +将“ ”转换为实际的粗体字体

Question

I am using the jTwitter plugin to get Twitter feeds. I am using it combined with a function that makes the links in the returned text click-able.

That function looks like this:

function replaceURLWithHTMLLinks(text) {
    var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
    return text.replace(exp,"<a href='$1' target='_blank'>$1</a>"); 
}

Everything works fine, except that the person who is sending the tweets is always trying to make parts of it in bold. And it looks like this <b>Bla</b> . It looks like this on his twitter site and also on my page.

I dont know what he does wrong and I dont care, I am just wondering if I could transform those in actual bold at my site by adding another few lines to the function above?

Answer 1

Check the source, there's a good chance that it i actually &lt and &gt instead of < and > . so do a regex that looks for <b>

Answer 2

note the 'g' flag that tells the replacement to apply to all of the matches.

function replaceURLWithHTMLLinks(text) {
    var exp = /(\b(https?|ftp|file):\/\/[-A-Z0-9+&@#\/%?=~_|!:,.;]*[-A-Z0-9+&@#\/%=~_|])/ig;
    return text
       .replace(exp,"<a href='$1' target='_blank'>$1</a>")
       .replace(new RegExp('&lt;b&gt;','g'),'<b>')
       .replace(new RegExp('&lt;/b&gt;','g'),'</b>');
}

Answer 3

This is just a guess, but is the Twitter plug-in returning the HTML escaped -

<b>

if it is you could replace the escaped content -

replace(new RegExp('&lt;b&gt;','g'),'<b>').replace(RegExp('&lt;/b&gt;','g'),'</b>')

Answer 4

the html characters have been encoded
