To find index of a string’s last character

Hi All,

I have a string “Level–1–Item–Arctic Cat–Quantity–2”, for which I want to have the output string as:

1 Artic Cat 2

The strings ‘Level–‘, ‘–Item–‘, ‘–Quantity–‘ are appended manually by me, and the ‘1’,’Artic Cat’ and ‘2’ are from variables.

Now I want to split the whole string using the strings which I have appended(‘Level–‘, ‘–Item–‘, ‘–Quantity–‘).

I am able to get the ‘1’ using

[CODE]values1 = “Level–1–Item–Arctic Cat–Quantity–2”
level = values1.substring(7,8);[/CODE]

which returned ‘1’.

Can anyone help me how to retrieve the ‘Artic Cat’ and ‘2’? I just played around the javasript string functions like substr(), indexof(), lastindexof(). But nothing worked out the way I want to.

var values1 = "Level--1--Item--Arctic Cat--Quantity--2"
var level = values1.substring(7,8);
var valuesArr = values1.split('--');
//now we have an array that looks like: Level,1,Item,Arctic Cat,Quantity,2
alert(valuesArr[0] + ": " + valuesArr[1] + "; " + valuesArr[3] + ": " + valuesArr[5]);


</script>[/CODE]

@mintedjoFeb 10.2009 — Hello.

This isn't necessarily the best solution but you could do something like this using a regular expression.

[CODE]var string = "Level--1--Item--Arctic Cat--Quantity--2"; //The string you start with
exp = /Level--(.*?)--Item--(.*?)--Quantity--(.*)/; //The regular expression
document.write([B]string.replace(exp, "$1 $2 $3")[/B]); //Use only the bits you want[/CODE]

This is what exactly I need. Thanks?
