Formular: Inputfield with UP/Down-Control element

Bobel

Hi,

I am searching for an Input box, where I am able as one possibility to
enter a number, and as an second possible action, click one of two
small buttons on the side to increase/decrease the number in the box.

a second small question, is it possible, to declare all the values, of
input boxes at the beginning of my HTML-document? (I mean values, that
are entered, at loading of the page)

thanxs

<form ...>
<input type="text" name="number">
<input type="button" value="+"
onclick="this.form.elements['number'].value++">
<input type="button" value="-"
onclick="this.form.elements['number'].value--">
</form>

The initial values of the input elements can be written as part of the
input tag: <input type="text" value"my initial value">
It is by far the safets way to do it.

You can use Javascript to enter the values later, but you have to wait
for the form controls to be loaded, and then the user might start filling
in the first ones before the later ones have loaded, and setting the
value later will overwrite the user's entry. It's dangerous, and I would
recommend against it.

<input value="my initial value">

For the typo and for `text' is the default value.

yes, i knew this, but I am processing my HTML-page, before sending to
the client, through a C-Programm, and, one thing i do, is replace a
tag, with the value of my text-box with the real number, if i could do
this, at the beginning of the programm trough javascript, i am able to
save time. (before you recomment it, the webserver is a small uC, so i
have no access to PHP or standart CGI-functions)

that shouldn`t be the problem, because at the moment, i only serve my
pages in a local net.

Thanx for your help
