Help with array searching

[womble]

Hi

This will be an east one for all you experts. I've never done scripting/programming in any form before and am driving myself mad with this one!!!!!!!

I need to search an array, which has 4 names in it, by inputting a string via window.prompt. If the name is not found I've got to ask them to re-enter their name. I'm not allowed to use a function as it's got to be straight code. I've also got another array with 4 entries and have to output the approriate message i.e. john is at names[0], therefore password is at password[0].

Hope this makes sense.

You can try adding something like this to your code, You'd have to adapt it to use window.prompt etc though.

PHP: Select all

var theName = "my name"; //This would be the input value from window.prompt

if(theName == names[0]) { //if theName is at names[0]

 alert(theName + " is at names[0]. Therefore password is at password[0]"); //show message of success

} else if(theName == names[1]) {//else if theName is at names[1] etc. etc.

 alert(theName + " is at names[1]. Therefore password is at password[1]");

} else if(theName == names[2]) {

 alert(theName + " is at names[2]. Therefore password is at password[2]");

} else if(theName == names[3]) {


 alert(theName + " is at names[3]. Therefore password is at password[3]");
} else {

 alert(theName + " has not been found. Please re-enter name");

}

Sounds like you need a Multi-Dimensionan Array. Or just 2 separate arrays. One for the names, and one for the passwords. 2 separate arrays will probably be easier with JavaScript than a multi-dimensional array. Then perform a loop and when you hit a match for the name, get the password from the password array at the same index. Just make sure you keep the names and the passwords at the same index in their array.

Good Luck,
