Question

I am new to PHP, JavaScript, and JQuery. Just thought it would be fun to build a Football Scoreboard. So after doing some research I came up with this. I'm sure there is a better way, but I have just been borrowing ideas from lots of articles at this site. I've run into a hurdle with Gridster. I believe it is writing the cookie correctly with my table positions. I've put the tables inside the listed items, because I couldn't get tables to work when defined as the widget_selector.

Here is my code. What do I need to do in order to read the cookie's position data and order my tables accordingly? Thanks very much for the help!

Solution

I figured out a way to do this with the following code. Seems to work in case anyone is interested...

if ($.cookie("grid-data") !== null) {
    var scorepos = JSON.parse($.cookie("grid-data"));   
}

for (var i = 0; i < scorepos.length; i++){
    var position = scorepos[i];
    var list = document.getElementsByTagName("ul")[0]
    list.getElementsByTagName("li")[i].setAttribute("data-row",position.row);
    list.getElementsByTagName("li")[i].setAttribute("data-col",position.col);
}
