I have a java web start application. And I need to make the browser pass the parameters to that application. The javascript function is taking the data from the url but is not yet passing to the other program.
It’s really hard to do that.
The javascript code looks like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1">
<title></title>
<script type="text/javascript">
function OpenInNewTab(url) {
var win = window.open(url,'_blank');
win.focus();
}
</script>
</head>
<body onload = OpenInNewTab('launch.jnlp')>
<script>
function ObterParametroUrl(parametro){
var parametros = window.location.search.substring(1).split("&");
for(var i = 0; i < parametros.length; i++){
var splitParametro = parametros[i].split("=");
if(splitParametro[0] == parametro){
return splitParametro[1];
}
}
}
var key_text1 = ObterParametroUrl('key_text1');
var key_text2 = ObterParametroUrl('key_text2');
if(key_text1 != ""){
document.UserInput.print(key_text1,key_text2);
}
</script>
<script>
alert("text1 " + key_text1);
alert("text2 " + key_text2);
</script>
</body >
The application that receives this code is like this:
package applet;
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
import java.io.BufferedWriter;
import java.io.FileWriter;
public class UserInput extends Applet implements ActionListener{
TextField key_text1;
TextField key_text2;
TextField key_output;
Label key_label1,key_label2,key_label3;
Button key_button;
@Override
public void start() {
print(getParameter("string1"), getParameter("string2"));
}
public void init(){
// Create layout
setLayout(null);
// Add different components to the layout.
key_label1 = new Label("Entre password1: ");
key_label1.setBounds(20,20,100,20);
add(key_label1);
key_text1 = new TextField(5);
key_text1.setBounds(150,20,100,20);
add(key_text1);
key_label2 = new Label("Entre password2: ");
key_label2.setBounds(20,50,100,20);
add(key_label2);
key_text2 = new TextField(5);
key_text2.setBounds(150,50,100,20);
add(key_text2);
key_label3 = new Label("Os passwords sao: ");
key_label3.setBounds(20,80,130,20);
add(key_label3);
key_output = new TextField(5);
key_output.setBounds(150,80,100,20);
add(key_output);
key_button = new Button("Get keywords");
key_button.setBounds(150,110,100,20);
add(key_button);
// Add action listener
key_button.addActionListener(this);
}
public synchronized void print(String string1, String string2){
this.key_text1.setText(string1);
this.key_text2.setText(string2);
}
public void actionPerformed(ActionEvent ae){
// Test t = new Test();
// String to get the user input texts
String str1= key_text1.getText();
String str2= key_text2.getText();
// Show output on the third text box
key_output.setText(str1+"--"+str2);
try{
// Create out put file
FileWriter fstream = new FileWriter("output.txt",true);
BufferedWriter out = new BufferedWriter(fstream);
// Write to the file
out.write("\n"+str1+";");
out.write("\t"+str2+";");
//out.write("\t"+str1+",");
// Flush the out put to the file
out.flush();
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
