AppendChild(), Remove Child()
Jul 23, 2005
I am trying to create one image using JavaScript; then later in the script
remove the image - not just remove the src. The following creates the image, but I have been unable to remove it.
How do I structure
document.getElementById('num1').removeChild(image_ display); ?
<input type=file name="picture1" onChange="image(this.value, 'num1');"
Id="pt1">
<div id='num1'></div>
<script type="text/javascript">
function image_size(field, num){
image_display=document.createElement('img');
image_display.src=field;
document.getElementById('num1').appendChild(image_ display);
..
..
..
document.getElementById('num1').removeChild(image_ display);
}
</script>

I am trying to remove a child node from an XML document and running into issues. I keep getting errors about not being able to find the child node, even though it very clearly exists.I think the issue is that most examples I've tried to follow only have the root element, then the nodes, but I have a root element, then another level (mapSettings & mapObjects). I don't know how to tell the remove child command that it needs to look in the mapObjects section.

so i wrote this slider with some help from an admin, everything works as I would like it to but I'm trying to make it a plugin so i need to tighten up a certain part of the code:
(function( $ ){
$.fn.jmSlider = function() {
// get total width of all li elements in the slider
var wrapWidth = 0;
[code]....
what i would like to do is instead of using "li:first" and "li:last", i would like to use first-child and last-child so the element doesn't need to be a li, in can be anything that is the direct child of the parent container.

I cannot get an appendChild(img) in the following code snippet to work in IE. However, the same script works without any problems in Firefox and Netscape 7.0 The error that is produced in IE is invalid argument. I have used a try/catch block in expectation of producing a better error message however the error message that is received is [objectError].
var pageDiv = window.parent.fraTop.document.getElementById('pageTitle');
if(pageDiv!=null)
{
while(pageDiv.hasChildNodes())
{
pageDiv.removeChild(pageDiv.firstChild);
}
var img = document.createElement('img');
img.src='/wp2f/images/please_wait.gif'
pageDiv.appendChild(img);
}

I have this body:
<body>
<div id="d1">content</div>
<!--I want to append a div right here-->
<div id="d3">content</div>
</body>
I have this javascript code which would add a div after div id="d3":
var adiv = document.createElement("div");
document.body.appendChild(adiv);
How could I modify my javascript code so that instead of adding to the end, making it the last tag, it would be the second tag?

I have a parent window that pushes a new window object onto an Array
with the following code :
OpenChild()
{
//totalNumWindowsCreated is global
totalNumWindowsCreated = totalNumWindowsCreated + 1;
childWnds.push(window.open(link, "child" +
totalNumWindowsCreated,"dependent"));
..
..
..
}
This pops up a new window with every call. In the child window I call
a parent function onbeforeunload, appClose() :
function appClose(){
if (window.opener && !window.opener.closed){
window.opener.CloseChild(getQueryString("application"));
}}
This is in my frameset tag of the child code :
<frameset ... onbeforeUnload='appClose()'>
The window.opener.CloseChild() function is called perfectly when I have
one child window open, but as soon as I create another child window
both of the open child windows don't ever call it. They do both go
into the onbeforeunload appClose() function, but do not call the
window.opener.CloseChild() function inside of this routine.
Anyone have any ideas why when I have two child windows open I can't
access the window.opener functions?
I have tried taking each new window out of the array and used the
following code in CloseChild() :
CloseChild()
{
//win and totalNumWindowsCreated are both global
totalNumWindowsCreated = totalNumWindowsCreated + 1;
var win = window.open(link, "child" +
totalNumWindowsCreated,"dependent");
..
..
..
}

I'm using the following code in a Greasemonkey script.
var start, newElement;
start = document.body;
newElement = document.createElement('b');
newText = document.createTextNode("The Greasemonkey salutes you!");
newElement.appendChild(newText);
start.appendChild(newElement);
Can anyone tell me: 1) why my string appears twice; 2) how to make it
appear just once?
I'm trying to insert code at the top of every viewed page. Obviously,
document.body appends the string to the closing body tag which is not
what I want. What could I use to insert my code as the first childnode
under 'body'?

var newText = parent.frames[1].document.createTextNode("some text");

This will insert an element after the last <p>, can I insert one

Over the last couple years I've built up a DOM library. Nothing fancy, you can just create an element with all its attributes in one function. What I've wanted to do is make it so you can determine the parent element of the newly created element. Works supa in firefox, not so supa in IE.This is my code....
Code:
pollOptions = document.getElementById("pollOptionsContainer");/*new divs to organize it in*/
pollOptionsGroupContainer = buildHtml.createDivHTMLElement(pollOptions);

function makeEdit (oldValue, pageID) {
alert (pageID);
var targetDiv = $(pageID.toString());
var inputBox = document.createElement("input");
inputBox.value=oldValue;
inputBox.id=pageID;
inputBox.onBlur="saveData()";

If I try to append a PARAM tag twice I'm having problems:
var.medDiv = document.getElementById("myDiv");
var medObj = document.createElement("object");
var p = document.createElement("param");
p.setAttribute("FileName",this.URL);
medObj.appendChild(p);
p = document.createElement("param");
p.setAttribute("AutoStart","false");
medObj.appendChild(p); // <-- this one
medDiv.appendChild(medObj);
The line with the "this one" comment triggers IE to tell me that it has
an invalid argument. If I change the order of the PARAMs then the new
second PARAM will give me the error. If I move the setAttribute to after
the appendChild I still get the error.

This example
will show that the first call to "doit()" will print 30 times the image
with only one call to the server. Then I have a timeout and call doit()
again, and this time, it downloads the picture 30 times!!!! It doesn't
even time to finish downloading the pictures before the next timeout
kicks off and if I let it go for a minute or two i have like 300 calls
to download the same image trying to be downloaded!
I heard about a bug in IE that would require to preload the images
using a hidden div, but that didn't work. I see that google maps manage
to not having to reload the image and gets it from cache. What am I
doing wrong? This works perfectly in Firefox (i.e. it uses the cache
and calls the server just once). Code:

I have a custom HTML tag: <custom>text is here</custom>
I can do anything I would like in terms of calling methods with mozilla
but not IE 6. For instance calling appendChild in IE results in an
error. The innerHTML property is blank even though there is text
between the tag.
Is there a work around for IE. What gives with IE and being able to
access and manipulate custom tags??

I have 2 list boxes - one to fill the second one based on the selection, or
move all items. You can remove the selection (or all items) from the second
one to place it back in the first one. I expanded my horizons and thought
to use script based on the js node operation appendChild(). It seemed so
clean and easy to follow. Works beautifully in IE, but Firefox sees the
value for a nanosecond but doesn't put it in the box. This is the relevant
js:
function addSide(){
var addIndex = document.forms[0].sides.selectedIndex;
if (addIndex >= 0)
{
document.forms[0].selectedSides.appendChild(document.forms[0].sides.options(addIndex));
}}
function delSide(){
var selIndex = document.forms[0].selectedSides.selectedIndex;
if (selIndex >= 0)
{
document.forms[0].sides.appendChild(document.forms[0].selectedSides.options(selIndex))
}}
function addAll(){
var len = document.forms[0].sides.length -1;
for(i=len; i>=0; i--){
document.forms[0].selectedSides.appendChild(document.forms[0].sides(i));
}}
function delAll(){
var len = document.forms[0].selectedSides.length -1;
for(i=len; i>=0; i--){
document.forms[0].sides.appendChild(document.forms[0].selectedSides(i));
}}
Is there a way to make it work for FF, or do I need to just start over and
not use appendChild()? Is there a better way?

I'm playing around with some AJAX-ish stuff and
encountered some problem in the JS side of the universe. Maybe someone
here can suggest an alternative that works.
I have developed a simple ASP.NET application with a web page that
should display a list of users. This list page is designed to start
with an empty table (with columns defined), and, onload, send an
XmlHttp request to a server component (a.k.a. ListServer). This
ListServer is currently simulating a long-running operation. So, it
sleeps for 3 seconds, and then grabs a list of 4 users from an xml
file. It applies an xsl transformation and returns the result.
The xslt is designed to take the xml data and convert it to a
<ListChunkroot element containing a <trfor each user in the XML
data. Each row contains 4 columns (Id, Login, Password, Name). The
javascript in the list page grabs the responseXML from the XmlHttp
object and should, for each <trin it, create a copy of the row
coming from the server and adding it to the list on the client.
I actually got all that to work quite fine. The js snipplet dealing
with copying the row coming from the server and adding it to the table
on the client is: Code:
