German is not a problem, but can you please edit your post and add [html] in the starting and [/html] in the end of your HTML code?

That helps people out here to find the problem quickly.

Please enclose your posted code in [code] tags (See How to Ask a Question).

This makes it easier for our Experts to read and understand it. Failing to do so creates extra work for the moderators, thus wasting resources, otherwise available to answer the members' questions.

Please use [code] tags in future. Thanks!

Unfortunately, there are lots of things missing in your code.

You may have a look at the following tutorial first:

Don't worry, I've added the code tags for you. Just remember to use them next time you post code.

As for your question, you need to access the numbers in some way. I assume that you want to total the items for which the checkboxes are checked. The best thing to do in this situation is to set the value of each checkbox to the number it represents. Then get each checked checkbox and add the numbers up.

To get all the checkboxes, use document.getEle mentsByTagName( "input"). Then loop over the checkboxes and check that they are checked. If so, add to the total.

Javascript can't delete server created cookie with no domain?

If I set a cookie value in the server code behind and don't use a domain then I can not change or remove that cookie's value on the client. If I subsequently create the cookie again in the codebehind then I actually end up with TWO cookies with the same name in the response. The cookie...

integers and arrays in Java - how?

by: Robert Baer | last post by:

I used Google and found some references for integer in Java. But "int" not only does not work, it also prevents reading X and Y coordinates of the mouse. What i would like to do: 1) Get X and Y mouse coordinates into a variable that i can do real math on. So far, i can do math on the values "read" and that result goes into a "variable" that is useful *only* for display. If i try "int" in that math, the values are then zero for everything...

It populates web page based on the contents of the database (resultset), and next to each row there is a checkbox (v1) allowing to select that row for changes (e.g. delete, update, etc.) So we are creating an array of checkbox, correct ?

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
