Please explain what a "javascript table" would be please. I've never heard of that phrase before.

Thanks!

Well as I understand it and I am new to javascript so forgive me. A javascript table is a table which is made using javascript code? I have my data selected from a drop down list and I am trying to capture it in a table before it gets submitted.

Thanks

I see, you want to add table rows to a table then, if I understand you correctly?
Does that table have a fixed amount of columns or will these also be dynamic?
What is your vision of the user selecting the values from the lists into the columns?

Is it possible that the four lists correspond to four columns and after selecting a value from each of the lists they are transfered into a new dynamically created row in your table by pressing a button "Add selections"?

I've composed this small example utilizing jQuery. I've spared my self the trouble of adding the part where the user can select entries from a drop down list as this does not seem to be your problem. This solution only concentrates on how elements can be added dynamically by using jQuery. Enjoy!

JavaScript

<html>
    <title>Add row to a table</title>
    <head>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
        <script type="text/javascript">
            function addRow(column1, column2, column3, column4)
            {
                $('#theTable > tbody:last').append('<tr><td>' + column1 + '</td><td>' + column2 + '</td><td>' + column3 + '</td><td>' + column4 + '</td></tr>'); 
            }
        </script>
    </head>
    <body>
        <h3>Add row to a table</h3>
        <input type="button" value="Add a row!" onclick="addRow('This', 'is', 'a', 'test');"></br>
        <table id="theTable" border="yes">
            <tbody>
            </tbody>
        </table>
    </body>
</html>

OK, it's Monday morning, and instead of doing useful work, I am trying to answer this question:

Most of the JavaScript naming conventions I have seen around the web say that most variable and function names should start with a lower case letter. Why is that?

Here. Probably because the JavaScript libraries use camel case (lower initial letter for variable and function names). Case is especially important in JavaScript, as the only way to differentiate a class and a function may be the case (as classes, in the form they are usually implemented, are functions).

Yes, but then how can you tell at a glance if something is a variable or a function? Other than parends after the function name. I had been using a convention of upper camel case for local variables and upper camel case for functions. But my co-workers tell me that I'm the only one in North America to do it like that. They also tell me my mom dresses me funny, too. Frown | :(

Javascript validation

Hi,

I have a simple validation of drop down list, making sure the user has selected either "yes" or "no". There are 3 of these dropdownlist, with values of "yes" and "no".

Based on if yes is answered, user needs to fill in two text boxes.

All this validation is performed using javascript.

while this works fine when test, now that the site is live, having some issues, where in the user is able to submit the form without filling in the dropdownlist!! I am trying to debug this, except it is consistently working for me. Totally lost. Any ideas please???

What happens if the user has Javascript disabled, by using something like NoScript or browser preferences?

Manfred Rudolf Bihy29-Sep-11 22:31

Good answer! 5+

Nowadays everybody seems to take javascript availability in a browser for granted. If base functionality of ones website does rely on javascript one has to make sure to check for it since, as you have already mentioned, the user might have disabled it.

Cheers!

That could depend on the browser being used.

Is there a way to escape the execution of javascript? Using IE7.0 and having scripting enabled?

Only thing new with this is this application is set up on a bran new server, which has https enabled. Do we need something set up on server for javascript to execute properly?

hi,

You can use both client as well as server side validation to perform your task..
First check user allowed javascript or not if yes then don't need to worry else you need to perform server side validation...........

Thanks & Regards
