updating values with getelementsbyid

[DennyLoi]

Hi everyone,

I am trying to update the value which is stored in a particular part of my page by using the getElementsById method, followed by calling a function to update the field. However, I don’t know how to do this. The relevant parts of my code are as follows:

[CODE=javascript]
function text(t)
{
return document.create TextNode(t);
}
function start(){

var oHelloText = text(getQuestio n()); //the getQuestion method returns a string from an array
oHelloText.id = "test";
}

function updateDetails()
{
document.getEle mentById('test' ) = text(getQuestio n());
}
[/CODE]
//sometime later, call to updateDetails method.

Unsurprisingly, this doesn’t work.

Any advice?

hi ...

as far as i can see you create a textnode from a string. but with that you cannot do:

[CODE=javascript]document.getEle mentById('test' ) = text(getQuestio n());[/CODE]
you cannot work with dom-nodes that way i think. you simply could do:

[CODE=javascript]document.getEle mentById('test' ).value = 'your_text';[/CODE]
or you should have a look at the replaceChild() method ... the text of your element to replace is a textnode with a textvalue itself ... so you have to replace it accordingly ...

kind regards

I see.

I went a layer up and gave the id to my P, which contains the text node.

I then wrote this (where 'test' now refers to the holder of the text node).

[CODE=javascript]function updateDetails()
{
var zzz = (document.getEl ementById('test '));
zzz.removeChild (zzz.firstChild );
zzz.appendChild (text(getQuesti on()));

}[/CODE]

This works, but doesn't seem very efficient. Is there a more suitable way?

hi ...

why do you use the complex textNode-way? you could set the value ... is there any reason that deserves the node-way for you?

btw: please use code-tags when posting source code ...

kind regards
