I am working on a regular expression to check the password field, Now the javascript that tests the varible is working, but when I try to call it and check the form I can’t seem to get the javascript to see that I want it to check the password in the form with the javascript I made but I can’t seem to get the form to commnuicate with the javascript I made, The form and the javascript are on the same page, what I want for it to do is after it checks the password requirements it will just go and submit the form. Here is what I have so far.

<html>
 <body>
    <script type="text/javascript">
     function checkPassword(password)
    {
    password = document.getElementById('thethePasswordFieldField').value;   
        var patt=/[a-z]/g;
        var patt2 = /[A-Z]/g; 
        var patt3 = /[0-9]/g; 
        var patt4 = /[~\!@#\$%\^&*_\-\+=`\|\\(\)\{\}\[\]:;"'<>,\.\?\/]/g; 

            var result=patt.test(password);
            var result2=patt2.test(password);
            var result3=patt3.test(password);
            var result4=patt4.test(password);

                if (!result)
            alert("Needs a lowercase & uppercase letter, a number & a special character.");

                if (!result2)
            alert("Needs a lowercase & uppercase letter, a number & a special character.");

                if (!result3)
            alert("Needs a lowercase & uppercase letter, a number & a special character.");

                if (!result4)
            alert("Needs a lowercase & uppercase letter, a number & a special character.");

                        if (result && result2 && result3 && result4)
            alert("");
            document.getElementById('frmApplication').submit();
    }
    </script>

    <form id="frmApplication" name="frmApplication" action="test.html" method="post">
    Password: <input type="text" name="thethePasswordFieldField" id="thethePasswordFieldField">  
   <a href="javascript:checkPassword()">Submit</a>
   </form>
    </body>
    </html>

    You’re using getElementById but have not actually assigned an ID attribute to the “password” field.

    Try:

    <input type="password" name="thePasswordField" id="thePasswordField"/>

    The reason I suggest using this convention is to avoid using “password” as your actual field name (IE will probably die if you use this method) and to also of course, actually use a password type field.

    Hopefully it should be obvious to you that your initial getElementById line must refer to the “thePasswordField” ID value.

    I have not vetted the rest of your code, but put the ID attribute in there and give it a shot.
