I'm having trouble getting document.write to work without using <. Is there an alternative method I can use to create a link instead?

It appears that this code only functions properly when using &lt; and &gt; instead of the regular characters. How can I adjust it so that it correctly links to the video owner's channel?

<script type="text/javascript">
    function youtubeFeedCallback(json){
        document.write("&lt;a href='youtube.com/user/"+json["data"]["uploader"]+"'&gt;"+json["data"]["uploader"]+"&lt;/a&gt;");
    }
</script>
<script type="text/javascript" src="http://gdata.youtube.com/feeds/api/videos/4TSJhIZmL0A?v=2&alt=jsonc&callback=youtubeFeedCallback&prettyprint=true"></script>
javascriptjsoncallbackyoutubedocument.write

Answer №1

let uploader = jsonData["info"]["author"], 
profileUrl = "youtube.com/user/" + uploader;
uploader.Link(profileUrl);

Answer №2

Using a different injection method instead of document.write() would be more advisable. Consider implementing the following code snippet:

<script type="text/javascript>
    function youtubeFeedCallback(json){
        var user = json.data.uploader,
            a = document.createElement("a");

        a.href = 'http://www.youtube.com/user/' + user;
        a.appendChild( document.createTextNode(user) );
        document.getElementsByTagName("body")[0].appendChild( a );
    }        
</script>
<script type="text/javascript" src="http://gdata.youtube.com/feeds/api/videos/4TSJhIZmL0A?v=2&alt=jsonc&callback=youtubeFeedCallback&prettyprint=true"></script>

You may need to adjust the location for inserting the link, but the concept is to shift away from using document.write() and opt for pure DOM insertion.

I hope this suggestion proves useful. Best regards!

Answer №3

json["data"]["uploader"] might include certain characters that could disrupt the formatting of your HTML code, such as a single quotation mark.
