How to get partial text item?

[BrainDonor]

I'm baaaack...:D

Hi everyone,
Lets say I have a 10 character variable called 'mytext' that I only want to view the last 8 characters...

If the SQL world the syntax would be mytext[2,10].

How would I do this in Java?

Any thoughts?

Thanks for your help!

Java or javascript both have pretty much the same syntax.

string.substring(start,end);
var string = "JavaScript is Different then Java"
alert(string.substring(2,10))


returns exactly as you had in sql

mytext[2,10].

Thanks much Khalid! Would I use the same logic then to test one character?

Should probably mention what I am trying to do is test the second character in a string to see if it's a comma...if so, reset it to nothing.

Thanks again!

for that you might wanna do this

if(string.charAt(1)==","){
//second char is comma
}else{
//second char is not comma
}

Not sure if this was the right thing to do or not, but I took two of your suggestions and blended them together. Here's how it ended up...seems to work quite well...

if (r < 0) {
var v = q;
var b = v.length;
if (v.substring(2,0) == '-,'){
var m = '-' + v.substring(2,b);
q = m;
}else{
q = q;
}
}

Thanks again for your help! I love this forum! :D

<!--
alert ('f,oo'.replace(/^(.),/, '$1'));

</script>

Wow, that's a lot easier than what I came up with. Thanks Charles. Can you explain what each part of the replace is doing? I want to make sure I understand it. Thanks again.
