Hi Guys,

This is a script designed in BASIC, I want to know its javascript compatible code, can you convert this?

This illustrate 3 TEXT BOXES (edit1, edit2, edit3) which are being used for this example.

--------------------------
Sub RegMe()
Temp1 = 0: Temp3 = 0: Temp4 = 0
Nam$ = Edit1.Text
Temp2 = Val(Edit2.Text)

For Temp1 = 1 To Len(Nam$) 'Gets each char of name
Temp3 = Asc(Mid$(Nam$, Temp1, 1)) 'converts each char to ASCII
Temp4 = Temp4 + Temp3 'adds each ASCII value
Next

Temp5 = Temp4 * 6 'Multiplies final ASCII by 6
Temp6 = Temp2 + Temp5 'Actual Number Of Registration Code
Edit3.Text = Str$(Temp6) 'Final Result

End Sub
---------------------

please convert and post javascript style solution, and I would appreciate it.

much Thanks :)

Did you even attempt to do this yourself?
How about you try that, and when you run into trouble, we'll help you debug it.

Is this something like you are looking for?

It only works for a-z 0-9 and pretty much regular characters. the list can be extended for use with whitespace/linefeeds/etc.

Also if you were using a different character set other than This, then the list can also be extended to encompass these.

Some wider reading can be found here:

function ascii(strInput, objOutput) { // pass up input string and output form object
var i, o, bln, strOutput;
strOutput = "";

var strChars = " !\"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~";

for( i=0; i<strInput.length; i++ ) {
bln = false;
char_loop:
for( o=0; o<strChars.length; o++ ) {
if( strInput.charAt(i) == strChars.charAt(o) ) {
bln = true;
strOutput += String("&#"+(32+o)+";"); // my ascii character list starts at ascii character code 32
break char_loop;
}
}
if(!bln) {
strOutput += strInput.charAt(i); // if character not found in - output the original character
}
}

objOutput.value = strOutput;
}
</script>
<style>
body {
font-family: "Courier New", Courier, mono;
font-size: 12px;
color: #000;
font-weight: bold;
}

input {
font-family: "Courier New", Courier, mono;
font-size: 12px;
color: #000;
}

textarea {
font-family: "Courier New", Courier, mono;
font-size: 12px;
color: #666;
}
</style>
</head>

<body>
<form name="frm">
Input:<br>
<input type="text" name="txtInput" size="50">

<br><br>
Output:
<br>
<textarea name="txtOutput" cols="50" rows="5"></textarea>

<br><br>
<input type="button" value="convert to ASCII" onclick="ascii(document.frm.txtInput.value, document.frm.txtOutput);">
</form>
</body>
</html>

Hope this helps - tested in IE, Firefox and Opera

Thanks Martin, I will check this.

Also, actually I only want this to be done via javascript.

VB/Script Solution = Javascript Solution
-----------------------------------------
Len() = ???
Asc() = ???
Mid$() = ???

so only three functions within Javascript (AND also with PHP if you know)

meanwhile I will search on the net for this one..

Thanks.
