Two (probably simple) questions

Hi,

Two quick questions:

1 I want to update the content of a div tag so I wrote the function:

[code]
function updateInnerHTML(theControl, theHTML) {
var newdiv = document.createElement(“div”);
newdiv.innerHTML = theHTML
var container = document.getElementById(theControl);
container.appendChild(newdiv);
//container.innerHTML(theHTML);
[/code]

The call to innerHTML didn’t work so I changed it to appendChild which is not the solution I want. Can anyone tell me why the innerHTML function wouldn’t work? I was passing in a short text string with no formatting.

2 I want to put my java functions in a seperate .js file and call them from my aspx file. I added the line:

[code]
<script type=”text/javascript” src=”JScript.js”>
[/code]

to the aspx file’s <head>. Is there anything else I need to do to call the functions in the js file?

Thanks to anyone who can help. I am totally new to javascript.

  • 1. Providing [I]theHTML[/I] is just text:var txtNode = document.createTextNode(theHTML);
    else use innerHTML after appending the element to the document.


  • 2. Depends on what the functions do.

    Thanks. How can I do it without having a new node appended each time the function is called? I plan to call the function from a button and I don't want multiple text messages displayed.


    2. Depends on what the functions do.[/QUOTE]

    The function I posted above: updateInnerHTML.

  • 1. You're creating a new div each time so there will only be one node.


  • 2. Calling from the button will work.

    Success!
