在JavaScript文件中获取buddypress用户名

Question

From within my buddypress PHP templates I usually get the username of any given user by referencing the user ID like this:-

<?php echo bp_core_get_username( '{{userID}}' ) ?>

However I need to retrieve the username from within an external Javascript file.

The user ID is already passed in as var aData[11]. I have tried the following with no luck:-

 $('td:eq(3)', nRow).html( '<div class="table-row"><a href="http://www.mysite.com/members/' + <?php echo bp_core_get_username( '"' + aData[11] + '"' ) ?> + '/song/?songsID=' + aData[10] + '"><h4 class="nomargin">' + aData[0] + '</h4></a>' + aData[1] + '</div>' );

I am trying to return a URL... This cirrently gives me:

http://www.mysite.com/members//song/?songsID=6

Whe it should be:

http://www.mysite.com/members/ username /song/?songsID=6

Any ideas?

Edit: Below is the server side code that I am using to ouput the JSON

<?php

The html you're setting is being set on the client side, not on the server side, meaning that the php code will not be evaluated.

I guess what you can do is either put the already-evaluated username in a hidden tag and get that using jquery or expose it to the javascript on the page within script tags.

EDIT : So is the userID or the username in the json as well? If not, you could probably put it there. I'm still not so sure what the situation is. But if you're currently passing the userID in the json and actually want the username as bp_core_get_username would return it, why not just put the already retrieved (with bp_core_get_username ) username into the json as well?

In other words, in your php code, figure out what the username is based on the userid with bp_core_get_username and then pass that into the json. That is, if I'm understanding the situation correctly.
