Re: Parent/Child Windows References

AFAIK, you simply can't. To put it in simple terms, the Javascript variables disappear after a page reload. After all Javascript is a client side technology.

A work around would be to store all the information you need to maintain inside a cookie i.e. whether the child window was open or not and if yes then what were it's contents; at the same time being aware of the 4KB limit imposed on the cookie size.

Re: Delete all rows from table in javascript

Re: FF vs IE dhtml/javascript/forms issue

> another odd thing, is that I do not see the form in the source when viewed by the client

Yes, because it's the Javascript object XMLHttpRequest provided by the browser at work when fetching content using Ajax. AFAIK, the actual DOM contents at any point in time can be viewed in Firefox using the tool DOM Inspector.

> onClick="javascript:validate_form();"
Don't use Javascript pseudo protocol. It was meant only to be used inside the href attribute of links.

One of the ways to narrow down your problem would be to put a DOCTYPE declaration at the top of your page (without which the browser goes in quirks mode of rendering, in short you have an invalid HTML document) and validate your generated markup at W3C validator.

The next step would be to use the FF error console for spotting errors which don't show up in IE just because IE let's them "slide".

Re: JSP ajax question

Since you need to set the bean in the session scope, you need to do something like session.setAttribute("YourBeanName", yourBeanReference); . Read the form values in a normal manner; the same way you would do for a normal form submission i.e. request.getParameter("formFieldName");

Re: Can you stop oracle storing < as < from a JSP inputText form field?

I would be assuming that you are using JSF as your UI framework here along with JSP as presentation technology. Even if you are not; the below discussion should be applicable to your problem more or less.

You have an 'escape' attribute for the HtmlOuputText since it's a display only entity and you might want to have complete control over how the data is presented to the client without manually doing the conversion every single time. HtmlInputText doesn't have an 'escape' attribute; actually it shouldn't have an escapeXml attribute since the data entered by the client should reach *as it is* to the server.

That being said, the only problematic area I see is the validation code which automatically converts all the < and > to their HTML Entities. It must be that even when the validation succeeds, the user input is still getting processed and converted to a String having HTML entities in place of < and >.

It might be a good idea to clearly explain your problem than to let the ones helping you out do all the guesswork. You bring up terms like HtmlInputText and validators as if they are commonplace here which isn't the case since they are not part of plain vanilla JSP API. Post the relevant code if you still encounter problems and don't forget to enclose the code in code tags; read the forum announcements regarding that.

Re: values lost on navigetion to next page and back

The code posted seems good enough though I am pretty much confused as to how these parts fit in the entire application or the page itself.

Values set in the session are not persisted across requests only when there is some problem with session creation. Make sure your localhost or your dev server is in trusted zone and cookies are enabled. Playing around a bit with the session object; i.e. setting some variable in session scope and retrieving it on the next page should give you a good idea on where exactly the problem lies.

You shouldn't be; the basics as well the pretty advanced stuff remains more or less the same. My recommendation would be the book 'Mastering Regular Expressions' which is a must read for all those who want to be regex gurus.

Though the basics are the same, the application of regular expressions depends a lot on the language you use, so unless you consult your language documentation, you might be in for a big surprise. :-)

Re: debugging?

You were having a hard time debugging this simple snippet because maybe you were testing this code in IE; for debugging use Firefox. It provides good debugging support given it has error console (Tools -> Error Console). To try it out, run your previous snippet which you just posted in Firefox and look at the error console; the errors would be right there.

If you are up to it, you can even try the Firebug plugin which provides full blown debugging. And you can be pretty sure that if something works in Firefox will also work in IE.

Re: Number Format Exception

There are no try...catch blocks around that switch statement of yours considering that any parseXXX method is very much capable of throwing a NumberFormatException. Plus writing parseInt(xxx) or parseDouble(xxx) in every switch case seems kind of redundant.

Also a status code of '0' denotes success so your System.exit(0) should be System.exit(1);

A better way to do the entire thing would be:

            System.exit(1);
        }

        double result = 0.0;
        ComputationUnit unit = new ComputationUnit();
        unit.populateFromCommandLine(args);
        try {
            result = unit.compute();
            System.out.println(unit.getOp1() + " " + unit.getOperand() + " " +

        } catch (IllegalArgumentException e) {

        }
    }
}

class ComputationUnit {

    private double op1;
    private double op2;
    private char operand;

    public ComputationUnit() {
        super();
    }

    public ComputationUnit(char operand, double op1, double op2) {
        this.op1 = op1;
        this.op2 = op2;
        this.operand = operand;
    }

    public void populateFromCommandLine(String args[]) {

Re: debugging?

Where have you declared 'slopetop', 'slopebottom' and 'slopefinal'? And document.write() is evaluated as the page is being rendered. Plus Javascript is a client side technology; as soon as a page is submitted, what you get is a new page and the state maintained in Javascript variables is reset.

You need to dynamically update the value of a span or div element to get this code working as expected. Something like:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"

      var elems = frm.elements;
      var x1 = parseInt(elems['inpx1'].value, 10);
      var x2 = parseInt(elems['inpx2'].value, 10);
      var y1 = parseInt(elems['inpy1'].value, 10);
      var y2 = parseInt(elems['inpy2'].value, 10);
      var e = elems['result1'];
      alert("(" + x1 + "," + y1 + ")" + " and (" + x2 + "," + y2 + ")");
      var distance = Math.sqrt(Math.pow(x2 - x1, 2) + Math.pow(y2 - y1, 2));
      e.value = isNaN(distance) ? 'Invalid input' : distance;
    }

Re: Can you stop oracle storing < as < from a JSP inputText form field?

Have you tried outputting the value in your servlet to see what it is receiving? Form values are submitted as they are; the job of encoding and decoding is automatically performed by your browser unless you are manually submitting the form using Javascript.

Also AFAIK, no database performs automatic conversion to HTML entities. Are you using any external libraries in your project? Anyways, printing the values submitted in a servlet would help us in coming one step closer to the solution.

If you are talking about getting the values of a drop down list at the server side, it can be done by doing request.getParameter("nameOfSelectBox"); A better way of displaying the user list will be render it as table with the user id hyperlinked which would then take the user to the corresponding page when clicked.

Re: Form without action "imitate" of other Form (which do have action) ???

form.submit() causes a form submit irrespective of whether that form has been assigned a real or dummy action. Plus on a page at a time only one form can be submitted. The best way here would be to rethink your design and encapsulate all the elements in the same form and perform the arbitration logic at the server itself.

First of all, your markup is broken. The HTML tag attributes need to be in the form of key-value pairs with the value being enclosed in double quotes.

This is because your JS code now looks for an element with the name 'fd' instead of 'field_0'. Try something like document.form1[fd].value .

But the way you are accessing forms is fundamentally broken, read this excellent article on form access.

Re: values lost on navigetion to next page and back

There are different ways of persisting data across multiple requests; session object being one of them. You can save the create a bean class for all logically related data and store its instance in the HttpSession.

Another way would be to use hidden form fields to pass values to and fro and maintain them across requests. The disadvantage here is that each time you land on a page, you need to create hidden form fields which would hold the data that needs to be passed to your target page.

Re: Works in IE but not in Firefox?

> The following works correctly in IE7 but doesn't work in Firefox. Any idea?

Because you are trying to retrieve the element using the id "testfield" but you don't have any element having an id "testfield", only one with a name "testfield". It works in IE because IE approximates or works with names if it doesn't find an element with a given ID. Form names are best accessed using the elements collection of the form object instead of searching for the element based on it's ID which is much slower. Read the Form access tutorial for more details.

Re: How to output random line from a file

I am not quite sure that I understand what you are trying to say here but if you are worried about the number of characters displayed per line on your console window, it depends on the properties of the console window (OS specific) and has got nothing to do with your program. For e.g. in Windows you can set the properties of the console window like Screen buffer and window size to increase / display the number of characters displayed.

If still in doubt, post the code along with the varying output you are talking about.
