Call Applet functions from website (js?)

**Fox** · Mar 4th, 2003, 05:17 PM

How can I call a function and pass parameters to a applet from my website? For example I want the user to enter name and password into textboxes and then click a button which calls the function login(name, pw) from my java applet. Best would be something using POST/GET but a javascript would also work..

There are several things why I don't want the textbox to be in the applet so please show me how to make website and applet work together,

Thanks

no one's replying and i don't know much about applets. but i'll give it a shot.

under the Applet there is a method called getParameter
http://java.sun.com/j2se/1.4/docs/ap...l#getParameter(java.lang.String)

i'm not sure, but if you could use that to pass in whatever info you need to be passed.
the api explains how it's used. check it out. goodluck

Nope that's only to read parameters from the website code..

<param name="text" value="hello world">

this one..

hmm...

have you browsed the api for more methods?

i just though of this. use php to get the input, put it in a cookie and read the cookie from the applet.. (although i'm not sure if that's possible)

i'm just spitting out possibilies.

Are you looking for something like this??

Code:

<HTML>
 <HEAD>
  <SCRIPT LANGUAGE="JavaScript">
   <!-- Begin
    function send_request(objForm)
     {
      var name = objForm.userid.value
      var pw = objForm.passwd.value
      
      // you might want to do some edits here, i.e.
      if (name.length == 0)
         {
          alert('Userid required')                 // displays in a message box
          objForm.userid.focus()
          return
         }
      if (pw.length == 0)
         {
          self.defaultStatus = 'Password required' // displays in the status bar
          objForm.passwd.focus()
          return
         }

      document.myJavaApplet.login(name, pw) 
     }
   //  End -->
  </SCRIPT>
 </HEAD>
 <FORM>
  <BODY>
   <!-- Note: HEIGHT="1" WIDTH="1" hides the applet -->
   <APPLET NAME="myJavaApplet" CODE="myApplet.class" HEIGHT="1" WIDTH="1"> </APPLET>
   <INPUT TYPE="TEXT" NAME="userid" SIZE="8">
   <INPUT TYPE="TEXT" NAME="passwd" SIZE="8">
   <INPUT TYPE="BUTTON" NAME="login" VALUE="Login" ONCLICK="send_request(this.form);">
  </BODY
 </FORM>
</HTML>
