Copy linkTweet thisAlerts:
Jan 09.2004

Hello EveryBoDy,

I want to insert this=
document.idform.id.value = id;

into a new function

function function1() {
document.idform.id.value = id;
}

But this is giving a error. (object not denified)

What have I done wrong??

Many Thanx

Jiser

@fredmvJan 09.2004 — We would have to see the HTML form as well as the rest of your JavaScript to accurately help you out. However, it's most likely one of two things:[list=1]
  • [*]You're trying to print the literal string "id" into the form element but you didn't quote it so JavaScript is trying to find a variable by that name, which doesn't exist, and thus you're getting that error.
  • [*]The form and form element doesn't exist.
    • [/list]

    @jiserauthorJan 09.2004 — Hi,

    here's my test-form:

    <form name=idform>

    <input type=text name=id>

    </form>

    @PittimannJan 09.2004 — Hi!

    If you use:
    document.idform.id.value = id;[/QUOTE]you'll need a form in your document with the name "idform" and a formfield with the name "id". You will also need to declare the variable called id and assign avalue to it...

    Cheers - Pit

    edit: something quite normal - fredmv is very fast (and accurate) ?

    @jiserauthorJan 09.2004 — any ideas?
    Copy linkTweet thisAlerts:
    @KorJan 09.2004 — you have an extra bracket...

    function function1() {

    document.idform.id.value = id;[color=red]}[/color]

    }
    Copy linkTweet thisAlerts:
    @PittimannJan 09.2004 — Hi!

    Yes, Kor! But to avoid confusion: jiser should not delete it. It belongs to the previous function, so it just has to be moved instead of be deleted:

    [COLOR=red]}[/COLOR]

    function function1() {

    document.idform.id.value = id;

    }

    Cheers - Pit

    @KorJan 09.2004 — Quite confusing fo a rapid glance

    he once use the brackets after an if statemnt, sometimes not....

    @clairec666Jan 09.2004 — Shouldn't everyone use brackets after if/else statements to avoid confusion? And indent the text when they open/close a brakets so you can see what part of the code is contained in a function/if statement etc.? I think dreamweaver does this for you, so you can find a way around your code easier (one reason for using dreamweaver and other coding tools)

    @jiserauthorJan 09.2004 — Hi,

    Still not working, it says= "id;" object not found. When I don't put it in a function (I inserted it into a function to load in the body handler) there is no problem.

    The whole script has to be inserted in the head of my masterscript but document.idform.id.value = id; only in one snippet. Thatswhy I wanted to call document.idform.id.value = id; only in this snippet using the body handler.

    Now I found I new solution to fool the browser:

    [list]
  • [*] add the whole code into one masterscript
  • [*] add

    <form name=idform>

    <input type=hidden name=id>

    </form>

    into the body
  • [*] add </script>

    <form name=idform>

    <input type=text name=id>

    </form> into that one snippet

    Thanx about everything
