javascript - Posting to a separate document using <form> and POST -
my first post here @stackoverflow. please bear me.
look @ code below. want javascript post php (applybeta.php) document if there '@' in field name & id 'epost'. if there isn't '@' in field, messagebox pop telling user entered invalid e-mail address.
if don't enter '@' message box shows up. if enter valid email doesn't post "applybeta.php", nothing happens @ all. got idea why? sorry if description vague, you'll figure out mean :)
the e-post field got both id , name because tried both, none of them works.
<!doctype html> <html> <head> <title>binärklocka</title> <meta charset="utf-8" /> <link rel="stylesheet" type="text/css" href="index.css"> <link href='http://fonts.googleapis.com/css?family=pt+mono' rel='stylesheet' type='text/css'> <!-- table font --> <link href='http://fonts.googleapis.com/css?family=lato:900italic' rel='stylesheet' type='text/css'> </head> <body> <script> function kollaepost() { var x = document.getelementbyid("email"); if(x.value.indexof('@') === -1) { alert("you didn't enter valid e-mail address!"); } else { document.getelementbyid("minform"); //z.submit(); //alert("hej"); } } </script> <div id="wrap"> <div id="main"> <br> <br> <table id="nav"> <tr> <td><a href="store.html">store</a></td> <td><a href="ourproducts.html">our products</a></td> <td><a href="index.html"><img src="home.png" alt="hem" width="60" height="60"/></a></td> <td><a href="aboutus.html">about us</a></td> <td><a href="contact.html">contact</a></td> </tr> </table> <hr id="linje1" /> </div> </div> <p id="binaryclock" onclick="showlink()"> looking beta testers our newly created clock!<br /> participate, fill in forms below real name</br /> , valid e-mail address , download link appear. </p> <!-- form want post --> <div id="applybeta"> <form action="apply.php" method="post" id="minform" name="minform"> <input type="text" placeholder="full name" name="name" /><br /> <!-- checking field '@' --> <input type="text" placeholder="e-mail" id="email" /><br /><br /> <!-- end of field --> <input onclick="kollaepost()" type="button" name="submit" value="send" /><br /> </form> </div> <!-- end of form --> <div id="dlink"> shdgfgh<a href="http://www.google.se">click here download</a> </div> <div id="bottomtext"> <p>@ 2015 clockmasters elite</p> </div> </body> </html>
instead of having input of type button, try submit. onclick-function can serve validation function returning true or false, , influence whether form submitted. this:
<input onclick="return kollaepost()" type="submit" name="submit" value="send" /> and:
<script> function kollaepost() { var x = document.getelementbyid("email"); if(x.value.indexof('@') === -1) { alert("you didn't enter valid e-mail address!"); return false; } return true; } </script> also see this question more detailed explanation on method, in general.
