Each element in the array contains quotes

<html>
<body>

<script type="text/javascript">
var i=blue;

var mycars = new Array();

mycars[0] = "'Sa'+i+'b'";


for (i=0;i<mycars.length;i++)
{
document.write(mycars[i] + "<br />");
}
</script>

</body>
</html>

i am having trouble displaying the mycars[0] element. Is there a way to display mycars[0] element?

This is the script that I am trying to utilize:

<script type="text/javascript">
function loadXMLDoc()
{
var xmlhttp;
xmlhttp=new XMLHttpRequest();
document.getElementById("rednoize").innerHTML="Checking..";
document.getElementById("hashcracking").innerHTML="Checking..";
var url=document.getElementById('ul').value;

if(url)
{
var md5_sites = new Array();
var results = new Array();
var md5_sites[0]= 'http://md5.rednoize.com/?p&s=md5&q='+ url +'&_=' ;
var md5_sites[1]= 'http://www.md5.hashcracking.com/search.php?md5='+ url ;

//rest of script

Firebug shows an error as: missing ; before statement line 38

Answer №1

Consider utilizing a different approach. For instance, implementing something along these lines should yield favorable results:

mycars[0] = "Sa{0}b";
for (i=0;i<mycars.length;i++) {
   document.write(mycars[i].replace("{0}", i) + "<br />");
}

This method of using a "template" is quite versatile and superior to resorting to the usage of eval.

Answer №2

The correct syntax is to declare a variable as var i = "blue" instead of just using blue, unless blue is defined as a global variable. Additionally, the line should be

mycars[0] = 'Sa'+i+'b';

This will output Sablueb.

Answer №3

When you see this in your code:

var i=blue;

What it's trying to do is assign the value of i to be equal to the value of a variable called blue. However, since blue has not been defined beforehand, you will encounter an Uncaught ReferenceError which causes the script to stop functioning.
