Hi, I am brand new to this forum nad pretty new to javaScript / spoiled by jQuery and I am struggling with a sign up form. So far I have it successfully perform an age check and set a cookie/change display depending on the answer. However an important piece (actually submitting the sucker) does not seem to be working. I also need to add better validation... right now I just have an alert popup.. how could I instead just have a hidden error message become visible. Would I use document.getElementByID('myID').innerHTML = "Set my styles in here?" I did have a cheesy email validation that just checked to see if it was blank.. if ( document.emailForm.email.value== 0 ) Code (markup): and I have found simple regEX like var emailRegex = /^([a-zA-Z0-9_.-])+@(([a-zA-Z0-9-])+.)+([a-zA-Z0-9]{2,4})+$/; Code (markup): however I am not having success integrating that into my script So any help with these issues and just general feedback about the script would be very much appreciated. Here is what I have so far... function createCookie(name,value,days){ if (days) { var date = new Date(); date.setTime(date.getTime()+(days*24*60*60*1000)); var expires = "; expires="+date.toGMTString(); } else var expires = ""; document.cookie = name+"="+value+expires+"; path=/"; } function readCookie(name) { var nameEQ = name + "="; var ca = document.cookie.split(';'); for(var i=0;i < ca.length;i++) { var c = ca[i]; while (c.charAt(0)==' ') c = c.substring(1,c.length); if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length); } return null; } var x = readCookie('age'); window.onload=function(){ if (x==null) { }; if (x=='over13') { document.getElementById('emailBox').innerHTML = "<img src=\"Thanks.gif\"><br /><p style=\"margin-left: 10px; width: 350px\">stuff<br /><br /"; }; if (x=='not13') { document.getElementById('emailBox').innerHTML = "<img src=\"Sorry.gif\"><br /><p>If you're under 13, you should not register or sign up for our email.<br /><br />..."; }; } function checkAge() { //first looks to see if any selection was made if ( document.emailForm.year.selectedIndex == 0 ) { alert ( "Please select your Age." ); return false; } //checks if selection is older than 13 var min_age = 13; var year = parseInt(document.forms["emailForm"]["year"].value); var month = parseInt(document.forms["emailForm"]["month"].value) - 1; var day = parseInt(document.forms["emailForm"]["day"].value); var theirDate = new Date((year + min_age), month, day); var today = new Date; //if they are not old enough display message and set cookie if ( (today.getTime() - theirDate.getTime()) < 0) { document.getElementById('emailBox').innerHTML = "<img src=\"Sorry.gif\"><br /><p>If you're under 13, you should not register or sign up for our email.<br /><br />..."; createCookie('age','not13',0) return false; } //if they are old enough display message and set cookie and submit else { document.getElementById('emailBox').innerHTML = "<img src=\"Thanks.gif\"><br /><p style=\"margin-left: 10px; width: 350px\">stuff<br /><br /"; createCookie('age','over13',0); var form = document.getElementById('theForm'); if(form != null) form.submit(); return true; }; }; </script> </head> <body> <div id="emailBox"> <div class="emailBox2"> <form id="theForm" method='post' name="emailForm" action="http://whatcounts.com/bin/listctrl"> <input type=hidden name="slid" value="234234"> <input type=hidden name="cmd" value="subscribe"> <table border="0" cellspacing="2" style="margin-left: 30px"> <tr height="30"> <td>Email <span class="red">*</span></td><td><input type='text' name="email" size="40"> <div class="emailError">Please enter your email address</div> </td> ... <td>Birthday</td> <td><select name='month' style='width:70px; margin-right: 10px'> <option value=''>Month</option> <option value="1">Jan</option> <option value="2">Feb</option> ... </select><select name='day' style='width:55px; margin-right: 10px'> <option value=''>Day</option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> ... <option value="31">31</option> </select> <select name='year' style='width:60px;' class="validate[required]"> <option value=''>Year</option> <option value="2007">2007</option> <option value="2006">2006</option> <option value="2005">2005</option> ... </select> <div style="float:right;margin:10px 0 0px 0px;"> <input type='image' src='signUpButt.gif' value='Submit' onClick="return checkAge()" /> Code (markup): and same thing at JS Bin http://jsbin.com/imesi3/edit Firebug shows the error that the form is null referring to this bit.. var form = document.getElementById('theForm'); if(form != null) form.submit(); return true; Code (markup): Thanks so much for any help!
