Hi,

I wrote a little sketch which should save data in a textfile on the server.

I use the netscape.javascript library to write a value from the applet to a hidden form. This form is then sent to a php-skript.

To my great happiness this works, but (and here my mood drops) only in internet-explorer. not in opera and not in firefox. there seems to be something wrong with my javascript, I guess.

Maybe you can give me a hint?

heres the code

processing:
Code:

 try
    {
	js = JSObject.getWindow(this);
    }
    catch(JSException e)
    {
	System.out.println(e.getMessage());
    }
  
    //test of calling javascript-function from an applet
    String args[] = {"234989898234"};
    js.call("setPoints",args);
 

javascript:
Code:

<script type="text/javascript">
<!--
function setPoints(args)
{
    var points = setPoints.arguments[0];

    document.getElementById("data01").value = points;

    document.forms[0].submit();
}
// -->
</script>
 

the HTML
Code:

<form action="appletDataWriter.php" method="post" name="form1">
    <input id="data01" type="hidden" name="points" value="" />
</form>
 

the php
Code:

<?php 

if(isset($points))
{
    echo $points;
} 
else
{
    echo "error during transfer of the value";
}
?>
 

the tip with filling the form inside the applet is nice. thanks.

but does not help with the different browser-behavior.

i did simple alert-output before and it shows the same results. In some browsers, the whle thing works, and in some not.

right now I am sitting at the university, using an apple. In safari the code works fine. In explorer/mac not at all.

hmmm, strange suff.

Maybe its a problem with different java versions? Could you take the example to the web?

isn't that because this is a netscape.javascript function, not for all browsers? .. that's what i've been told at least..

but still.. my class removes the use for javascript, at least the filling in hidden textfields, and then posting, to just insert the fields in a string array, with the corresponding values in another array, and post it, and you'll just have to set up the phpfile to $varName = $_POST['name'] if you have a parameter named 'name'..

in other words, the class just posts straight to a phpfile, and seems to work in all browsers..
rewrite it till it suits you.. or ask me for help, if it gives you any trouble

java just uses http GET, and we dont' have a POST implementation built into processing. although a quick google search oughta turn up some simple code for doing a POST in java, i know i've done it before but i don't have the code handy..
