    Newbie question - line continuation and hash sign

    I'm a newbie when it comes to JavaScript, could you please help me understand what does it mean in the code below which is only a part out of a larger js file:

    Code:
    1.
    var o = self.getTheDamnLink(e);
    
    2.
    o.href = jQuery(o).data('song_link');
    
    3.
    if (o.nodeName.toLowerCase() != 'a') {
    
    4.
    var o = self.isChildOfNode(o,'a');
    
    5.
    if (!o) return true;
    
    6.
    }
    
    7.
    var sURL = o.getAttribute('href');
    
    8.
    if (!o.href || !o.href.match(/
    
    9.
    var o = self.getTheDamnLink(e);
    
    10.
    o.href = jQuery(o).data('song_link');
    
    11.
    if (o.nodeName.toLowerCase() != 'a') {
    
    12.
    var o = self.isChildOfNode(o,'a');
    
    13.
    if (!o) return true;
    
    14.
    }
    
    15.
    var sURL = o.getAttribute('href');
    
    16.
    if (!o.href || !o.href.match(/\.mp3(\\?.*)$/i) || self.classContains(o,self.excludeClass)) {
    
    17.
    o.href = jQuery(o).data('not_mp3'); // re-assign the non-mp3 link
    
    18.
    return true; // pass-thru for non-MP3/non-links
    
    19.
    }
    
    20.
    sm._writeDebug('handleClick()');
    
    21.
    var soundURL = (o.href);
    
    22.
    o.href = '#';
    
    23.
    var thisSound = self.getSoundByURL(soundURL);
    
    24.
    #46;mp3(\?.*)$/i) || self.classContains(o,self.excludeClass)) {
    
    25.
    o.href = jQuery(o).data('not_mp3'); // re-assign the non-mp3 link
    
    26.
    return true; // pass-thru for non-MP3/non-links
    
    27.
    }
    
    28.
    sm._writeDebug('handleClick()');
    
    29.
    var soundURL = (o.href);
    
    30.
    o.href = '#';
    
    31.
    var thisSound = self.getSoundByURL(soundURL);
    The / and the #?

    I've read that the forward slash / is actually an indication that the code can continue on the next line.

    However, I couldn't find anything related to the hash character... on the line that starts with #46.

    I found this code here:
    https://getsatisfaction.com/schillma...#reply_4980199

    Can somebody help me understand the above forward slash and the # sign.
    I also find wired this line of JavaScript code:
    if (!o.href || !o.href.match(/

    because even though I understand that the forward slash is just to allow the text to continue on the next line, the next line does not look like a continuation of the IF condition...)

    Many thanks

    Padonak, thanks for that, I thought that I was a bit slow in understanding that code.
    It's not my code....

    What would be the solution, or how to re-write it to make it work?
