Thread: Edit Web app

Are you asking how to make changes to a page of html?

How does this relate to java programming?

If you don't understand java programming, what do you expect to happen?

If you are having problems with java code, paste the code here and ask some questions about the problems you are having.

Try asking those questions on a javascript forum.

It used to be able to. I'm not sure what the current version of java allows.

I have an html page with an applet I use locally. This code is 8 years old.
This code calls the applet from a javascript function:

   // Start the search	 
//    alert("startSearch with " + str); 
    document.MyApplet.startSearch(str);
 
..... Later in same page:
 
<APPLET  CODE=SearchApplet name="MyApplet" archive="SearchFiles.jar"
           id ="MyApplet" width="1" height="1" codebase="." MAYSCRIPT>
 <PARAM NAME=Source Value="E:/">
 <PARAM NAME=Depth  Value=8>
 <PARAM NAME=Mask   Value="*.html">
 <PARAM Name=Debug  Value="YesXXX">
</APPLET>

Then in the SearchApplet class:

  //------------------------------------------------------------------------------------
   // Called from JavaScript to start the search and build a new window with the results
   public void startSearch(String s) {

To talk to the browser:

 netscape.javascript.JSObject   win = JSObject.getWindow(this);
 
...
 
   //---------------------------------------------------------------------
   // Write the results to a new Window
   private void writeToWindow(String txt) {
      // Problem if text contains HTML control chars???
//      String outText = txt.replace('\n', ' ').replace('\r', ' ').replace('"', '\'');
      // Use a simple string - fails with \n!!!
//      outText="Does this make it to the window?\\n On two lines!";    // simple string WORKS???
//      System.out.println("outText=" + outText + "<");
 
      try {
         //  Create the window           
         win.eval("var newWin=window.open(\"\", \"\","
            + " 'width=700,height=400,top=0,left=0,"
            +"resizable=yes,location=yes,toolbar=yes,scrollbars=yes,status=yes,menubar=yes');");
 
         // Now put some text in the new window
         ByteArrayInputStream bais = new ByteArrayInputStream(txt.getBytes());
         BufferedReader br  = new BufferedReader(new InputStreamReader(bais));
         String line = "";
         while((line = br.readLine()) != null) {
            line = line.replace('"', '\'').replace('\\', '/');  // <<<<<<<<< NEEDS work HERE
            // Other changes ???
            win.eval("newWin.document.write(\"" + line + "\\n\");");
         }
         win.eval("newWin.document.close();");  // Where does this go???
      }catch(Exception ex) {
         ex.printStackTrace();
      }
   } // end writeToWindow()
 
} // end class
