hello everyone I am trying to make a script that steps through a list

hello everyone I am trying to make a script that steps through a list and appends a score to each record returned by the query. this code below is what’s happening in PHP; a input is created where I store the number that’s going to be processed in a string; below that there is a span element that displays the text score and another span that contains the actual score. Finally there’s an echo that showcases the values generated which look like: score_pad0, score_pad1, score_pad2 

echo "<input type='hidden' id='fetch_array' value=".$score_board." />";
echo "<span>score: </span><span id='score_pad$score_board'></span><br />";
echo "score_pad$score_board";

I want to grab the value from fetch_array in javascript. I use the following code for that
var array_id = document.getElementById('fetch_array'); this however returns null when I run it. What am I doing wrong? I’ve tried to read it out by adding the .value extension. but it only crashed my javascript code.

the onload event is triggered by the a function

function initialize(numbers_rows)
{
for(var i=0; i < numbers_rows; i++)
{   
    var node=document.createElement("span");
    node.id="scoreLabel";
    document.getElementById("score_pad"+array_id).appendChild(node);
}
}

    There is a possibility that the time your javascript code gets executed your DOM might not be ready. As a trial do <body onload='myFunction()'> and wrap your document.getElementById inside myFunction()

    If does work incase you wish to have multiple handlers for onload event you need to use
    addEventListener DOC for non IE browsers and attachEvent for IE.

    If you could use jQuery then wrap your javascript code around

    $().ready(function () {
 // Your Code Goes here &Will be executed after DOM is ready
});
