Compare 2 Arrays
by Hiyatran » Fri Dec 16, 2011 1:57 am
I have 2 arrays and I would like to compare the 2 arrays.
If an element in array 1 is NOT in array 2 then I would like to display that element.
In this case, I should only display the letter "c" but it doesn't work and I don't know why??
Here's my code:

Here's my code:
- Code: Select all
<html><head>
<script type="text/javascript">
function getValue(id){
var x=new Array("a","b","c","d","e");
var y=new Array("a","b","3","d","e");
var str="";
for (var i=0; i<x.length; i++){
for (var j=0; j<y.length; j++){
if (x[i] == y[j]){
break;
}else{
//Check if reach the last element in the array 2
//If yes, then display that element in array 1 b/c not in array 2
if (y[j] == y.length-1){
str += x[i];
}
}
}
}
document.getElementById(id).innerHTML = str;
}
function init(){
getValue("info");
}
</script>
</head>
<body onload="init()">
<h2 id="info"></h2>
</body>
</html>
