Hello,

How the heck should I make this simple summering of a data without a
submit button?

Like in an excel sheet I would like to have a couple of cells in a
column and as soon the visitor types the number the sum should change,
regardless of how many raws there are and based on the setting
(adding, multiplying etc).

I would appreciate the code, link to the code or suggestions.

Thanks in advance. :)

您可以使用（on）keypress事件来捕获用户的数字

类型。最简单的方法就是简单写一下


yourInputElement.onkeypress = yourOnkeypressFunction;


其中yourOnkeypressFunction是一个处理事件的函数。

You can use the (on)keypress event to capture the numbers the user
types. The easiest way is to simple write

yourInputElement.onkeypress = yourOnkeypressFunction;

where yourOnkeypressFunction is a function that processes the event.
