Undefined?

[Mike]

I've created a plugin and for some reason it just shows up as undefined.
Can someone help?
My site

First fix up the missing script tag on this code...

<script type="text/javascript">

$(document).ready(function() {
 $('#move-shoutbox').append($('div.shoutbox.container.full'));
});

As for your undefined issue.  It's because you are trying to run code when the board object doesn't exist.

pb.data('page').board.name

Either check the route then use the board object, or check that board exists before attempting to access any of its props.

I'm not sure what you mean about the board object

[Mike]

Alright now I made some changes and still I'm getting Undefined
Can anybody help?

$(document).ready(function(){
var help=pb.plugin.get('closet').settings.settings;
for(p=0;p<help.length;p++) {
var board=help

.board;
if(board.length > 0){
for(r=0;r<board.length;r++){
if(pb.data('page').board.id==board[r]){
var text=.tex;
var dot=.ad;
var pict=.pic;

}
}
}
}
var bod_man='<div id="shelf">';
bod_man+='<img src="'+pict+'"><a href="'+dot+'" style="font-size:17 px">'+text+'</a>';
bod_man+='</div>';
$('#shelf').html(bod_man);

});

The error remains

There would be no "board" in pb.data('page') when you are on a page such as the homepage or a profile page, the "board" object is only populated with the characteristics of that board (name, id, etc.) when you are in an actual board otherwise the board object is undefined, this is critical! You have to grasp this concept in order to proceed! You cannot get the "id" from something that is undefined!

I don't understand I used pb.data('page').board.id in other plugin before and it worked.Can you further explain?
I'm not grasping it.

[Chris]

You're kidding right?

[Mike]

Chris
No man i'm serious
How do you define the board?

[Brian]

You don't. There's no way to forcibly define it. You need to check whether or not it's defined before running any code that handles pb.data('page').board.id.

pb.data('page') always exists, but contains different things depending on the page that you're on. pb.data('page').board and everything within it only exists when you're inside a board.

You can type pb.data('page') in your browser's console to see what exists within the object on that particular page.

Sorry man for not replying.Thanks for your help

Hello,
I got this plug-in working right for the most part, it shows up on the board I assign the message but the other board has undefined on it. anyway I can get rid of the undefined from that board?

[Brian]

mess is returning as undefined because your code only defines it if you're in a board that you've added a message to in the plugin settings. Use an if statement to check if mess exists before adding HTML to the element it's affecting.

if(mess){
    var substruct='<div id="boardsubs">';
    substruct+='<h1 style=" color:#'+colr+';font-size:'+sze+'px;text-align:'+aln+';font-weight:'+wht+';font-face:inherit">'+mess+'</h1>';
    substruct+='</div>';
    $('#boardsubs').html(substruct);
}

While you're at it you should add an if statement around your entire code checking for the existence of pb.data('page').board before running any of your code. It's throwing a bunch of errors on the homepage because it's trying to handle pb.data('page').board.id when it doesn't exist. Realistically your plugin shouldn't error anywhere.

if(pb.data('page').board){

// Your code here

}

You can press F12 to open your browser's console and check for any Javascript errors thrown by your plugin.

Thanks Brian
That works but I think i'm going to use this thread as a ref so I won't ask about this again. Another thing can I use prepend instead of html
$('#shelf').html(bod_man);
will this take the place of the Place holder div?

[Brian]

Using html() on an element will replace the entirety of its inner HTML with what you specify.

api.jquery.com/html/


Using prepend() will add whatever HTML you specify to the beginning of the element's existing inner HTML.

api.jquery.com/prepend/
