Dynamically change regex in textfield problem

[altamirador]

Hi !

Once again, I need help from the community ! I have a form from which I wish to validate a captcha that I have created. I load the captcha image from php and this part works pretty well. At the same time it loads, I pass the captcha value in a cookie. This works well also.

But, here's what I'm trying to do: When I get the image refreshed, I get the cookie and change the regex value from he form's field:


var RegularExpression = new RegExp(readCookie('captcha')); // captcha value converted to regular expression
Ext.get('FCaptcha').regex = RegularExpression; // assign to field named FCaptchaThat does not generate any error however, the field does'nt validate ??

Any ideas ?:((

It's the part in blue I'm not so sure about !!!

Ext.getCmp('FCaptcha').regex = RegularExpression;
Ext.getCmp('FCaptcha').validate();

What's the cookie value? Is it a valid String to be passed into a RegExp constructor to get a value RegExp from?

Stop in debug and find out! And test the resulting RegExp on the command line to see if it does what you think it does.

Thanks !

It's just a simple string like '12ji3pl' and the regexp returns /12ji3pl/

Solved !

Looks like the cookie is not ready when I assign it. Basically, I'm getting the old cookie assigned to the field.

I need to find another approach.

Thanks for your inputs !

You are completely killing the captcha concept!

The whole point of this kind of validation is that a script can't generate an automatic response. Did you forget that a script can also read a cookie value?

Yes you are right to a certain extent...My cookie is encrypted...
