Check for correct form

[dezkit]

Is it possible for javascript to see if the text inputted is in the right form?

 

for example

 

i have

 

<input type="text" name="SteamID">

 

and the form of the input has to be "STEAM_0:x:x"

(first x is 0 or 1, second x is any number in infinite amount)

 

 

Thanks.

You can use regex in javascript: http://www.regular-expressions.info/javascript.html

So something like this would probably work:

<script language="Javascript">
myregexp = new RegExp("STEAM_[0|1]:[0|1]:[0-9]+"); 
isSteam = myregexp.exec("STEAM_0:1:3945");
</script>

If 'isSteam' is null, then it is in the wrong format.

the code doesnt work . im a noob in javascript

 

this is what i have in my page:

<script language="Javascript">
myregexp = new RegExp("STEAM_[0|1]:[0|1]:[0-9]+"); 
isSteam = myregexp.exec("STEAM_0:1:3945");
</script>
<form action="confirm.php">
<input type="text" name="SteamID">
<input type="submit" value="submit">
</form>

Possibly use .match instead of .exec.  And then check if isSteam is true or not

That was meant to be an example, not the actual code.

<script language="Javascript">
myregexp = new RegExp("STEAM_[0|1]:[0|1]:[0-9]+");
</script>
<form id="frm" action="confirm.php">
<input id="tBox" type="Text" name="SteamID">
<button onClick="if(myregexp.exec(tBox.value) == null)alert('Not Steam ID format');else frm.submit();">Submit</button>
</form>

 

That should be closer to the way you want to use it.
