DOM Javascript - Imbed Javascript In Dynamically Added Row
Jul 23, 2005
Attached is a simple HTML file that adds and delete rows. In the add
row function I set an attribute "onClick" this triggers the
testMessage() function. When I try this in Firefox it works just fine
however on IE it just refuses to work.
What is interseting is the ROW that already exists has a similar
'onClick' event which works when the page is loaded, but subsequent
"row" additions to the table to not work in IE. Code:

I'm working on some code and am running into brick walls. I'm trying
to write out Javascript with Javascript and I've read the clj Meta FAQ
and didn't see the answer, read many similar posts (with no luck
though), and searched through the IRT.ORG Faqs
(www.irt.org/script/script.htm).
The Javascript is designed to open an popup window and then inside that
window call another script which will resize that window. There may be
another way around this but the reason I tried this approach initially
was that I wanted to call the onload handler in the popup window to
resize the image only after the image had completely loaded. I've had
some code in the primary Javascript file (showimage.js) before that
works if the image has been cached but on the first load, it doesn't
resize properly which tells me it is probably because it is trying to
resize the window based on the image size but it isn't completely known
at that point. So I removed that code and tried placing the resizing
code in the second Javascript file (resizewindow.js). BTW I've tried
other code to open a popup image and automatically size it ie Q1443 at
irt.org but that doesn't do exactly what we need.
Even if there is another way to do this with one file, I still want to
figure out why this isn't working in case I run into it in the future.
I thought what I would need to do to use document.writeln to write
Javascript would be to escape any special characters and to break
apart the script tag ie
document.writeln('</SCRIPT>');
would become
document.writeln('</SCR' + 'IPT>');
I have a HTML page and 2 Javascript files. All files are in the same
directory and have permissions set correctly.
Here are the 3 files (keep in mind wordwrap has jacked up the
formatting):
index.html
----------
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Test</title>
<SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1"
SRC="showimage.js">
</SCRIPT>
</head>
<body>
Click the house<BR>
<A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG
SRC="house1thumb.jpg"></A>
</body>
</html>
showimage.js
------------
function newWindow1(pic,sitename)
{
picWindow=window.open('','','width=25,height=25,sc rollbars=1,resizable=1');
picWindow.document.writeln('<html> <head>');
picWindow.document.writeln('<SCR' + 'IPT type="text/javascript"
LANGUAGE="JavaScript1.1" SRC="resizewindow.js"></SCR' + 'IPT>');
picWindow.document.writeln('</head>');
picWindow.document.writeln('<body onload="resizewindow();">');
picWindow.document.writeln('<img src=' + pic + '>');
picWindow.document.writeln('</body> </html>');
picWindow.document.close();
}
resizewindow.js
---------------
function resizewindow()
{
// Do resizing here.
// Right now this isn't being executed
alert("resizing window");
}
Can anyone provide some pointers as to why this javascript is failing?
I'm using IE6 on Win2k and when I click on the image to open the popup
window, it does open the window but it is white with no content and the
system immediately goes from about 4% CPU usage to 100% and
consistently stays there until I kill that window with the task
manager.

This javascript is meant for learning language vocabulary, specifically
colours on this example. However, when I use images in the mtWord array,
it breaks when checking for correct answers. It works fine with text in
those spaces. Code:

I'm adding people to a database. People have a first name, last name,
and a undetermined number of Cities and States with which they can be
associated. I've got a drop down box that I would like to use to
display the number of inputs to allow for city/state entry. I would
like to dynamically increase or decrease the inputs based on a user
changing the selection in the drop down box, without submitting the
script. Only the first city and state are required (which is why the
label is bold). Any ideas on the best way to handle this without
losing any potential city information that may have been previously
typed into the input (i.e. if I type San Fran into city0 and CA into
state0 and then change the number of cities to 4 - I'd like San Fran
and CA to still be populated in city0 and state0). Code:

I'm currently looking at data-piping ie making server calls without reloading the page, the server returning some data to a cookie and the calling page using that same data on the page using DHTML. So far so good...
But is it possible to actually use javascript to actually write more javascript onto the page? Or, alternatively, is it possible to dynamically add a call to an external javascript file.
Something like...
document.writeln('<script src="script.js")
The idea being that the server could return functions for the calling page to use, which would be very nice for complex web applications.
If you can do this, what issues do you need to be aware of?
If you can't, are there any ways of achieveing the same things? I'm thinking of things like dynamically adding a scriptlet call to the page in Windows IE, though a more cross-browser solution would be cool.

Might there be a way to add a set of Javascript functions to a display page's existing set of Javascript functions on the fly without reloading the display page, and if so, how?
A couple of approaches I have tried, but without success are:
- A) For an embedded "retriever" IFrame in the display page to retrieve a set of JS functions from the server and then on its "onload" transfer (by innerHTML transference) that set of functions into the parent display page.
- B) Similiar to "A" but to use regular old browser frames - one being the "retriever" and one being the display page.
- C) Using a JS function in the display page to make a http request for a supplementary .js file(s).
Please note: the goal is to retrieve *only* an additional set of Javascript functions from the server, and then add them to an "original" set of functions already loaded into the browser. Meaning, NOT - say - for an IFrame to download from the server *both* the additional set and again the "original" set, which the parent display page could then run directly from the IFrame.
After "A", "B", and "C", I'm at a loss for further ideas.

I have been struggling with a cross browser solution to loading
external javascript files on the fly.
I have been successful using the following code in IE6:
var newScr = document.createElement("SCRIPT");
newScr.src = "newScr.js";
newScr.type="text/javascript";
document.getElementsByTagName("head")[0].appendChild(newScr);
I believe the reason is that IE is loading the external file
syncronously while Firefox is not. Is there an onload event for
creating an element (if so I do not see it in Venkman). I have seen the
solution of using XMLHTTP to load the script but I am trying to get
around any dependency (atleast at this stage of the library) on
activex.

My client wants to upload multiple files to the server using the FILE type input of the form. Their requirement says that once they click the browse button of the FILE INPUT type , besides file browsing window another FILE FIELD is added at the bottom of this one. and when the user clicks the browse button of second, it adds another until the user clicks the UPLOAD button to submit the form.
I dont know it is possible or not ???? if yes then please tell me how.
The alternate way is to give drop down menu with number and when the USER chooses certain number then ..that amount of FILE FORM FIELDS will be added. i.e if user chooses 3 then three file fields are there to upload 3 files at a time.
I have written a script that i am pasting here, but when i choose the drop down menu and select value the FILE FIELDS are shown but the original drop down menu vanishes..
Please review my code and modify it or refer some script to me.
IF The first choice is possible, i mean adding each FILED by browse button click , then tell me its code, other wise modify this code that i am pasting or give me some link to download a premade script. Code:

Ive been banging my head on the wall for hours with this one, hopefully
someone will know what Im doing wrong here :
The Goal:
I have an xml file that is generated on the fly via JSP which I want to
load into a Microsoft.XMLHTTP ActiveX object and manipulate via
javascript on the client side. Data is retreived from the server at the
request of the javascript without having to reload the page.
The Problem:
For the JSP to dynamically output xml, the file must have the extension
JSP, which is set to the mime type of dynamo-internal/html on the
server side (as we are using ATG Dynamo). But the javascript on the
client side will not retrieve anything unless the file extension is
..xml (or the mime type is recognized as text/xml). So the only way I
can get it to work is to change the extension to .xml, which then of
course amkes it so that the server will not process any of the JSP
code.
Ive tried to override the mime type within the javascript, using the
setRequestHeader method after opening the file, but no luck. A call to
alert the value of req.responseXML.xml after the send() turns up empty.
Ive only gotten it to work if I use a static xml file in palce of the
jsp. Sample of the javascript code is below:
if (window.XMLHttpRequest) {
// branch for native XMLHttpRequest object - THIS WORKS
req = new XMLHttpRequest();
req.overrideMimeType("text/xml");
req.onreadystatechange = processReqChange;
req.open("GET", "models.jsp?cId=300006&mId=TAC24", true);
req.send(null);
alert(req.responseXML.xml); //this gives me the resulting xml file
} else if (window.ActiveXObject) {
// branch for IE/Windows ActiveX version - NOT WORKING
req = new ActiveXObject("Microsoft.XMLHTTP");
if (req) {
req.onreadystatechange = processReqChange;
req.open("GET", "models.jsp?cId=300006&mId=TAC24", true);
req.setRequestHeader("Content-Type","text/xml");
req.send();
alert(req.responseXML.xml); //this gives me nothing
}
}
In looking at the following example the Microsoft gives (bottom of
page):
http://support.microsoft.com/defaul...B;EN-US;Q290591
I just dont see what could be going wrong here.
I should note that I successfully got the script to work using the
XMLHttpRequest object and the overrideMimeType() method. This works
with FireFox and I think some Mozilla clients, but not with the all
important IE5, which instead uses the XMLHTTP ActiveX control.=

I've found a few posts on adding an event to a dynamic element, but that doesn't really help me. What I'm doing is allowing the user to add a textbox, then when a button is clicked i need to find the value for that text box, but it doesn't seem to pick up that the textbox is there.
Oh and that textbox is part of an array of textboxes, all of whose values i need.

I have a form where the users can add "name" and "id" fields by clicking on the "Add" button.
The input fields look like this (each pair is a row):
The 'name' and 'id' attributes are dynamically named with the integer increasing in value, by 1, for every new field.
As this is client controlled, I do not know how many rows there will be...

In my application I render a couple of elements dynamically after the user selects an option in a dropdown list. When the user selects another option in the dropdown, I want to remove all the previous elements that was added dynamically. I've tried with the .Remove() function, but it seems the elements cannot be found in the DOM. I've looked a lot at the .live() events.

I have the following html:
<div id = "container"></div>
<div id = 'containerItemTmplt' class = "ui-widget-content">
<div class='contentHdr' onclick="test(this)" />
</div>
i then use jquery to clone 'containerItemTmplt' and add it to 'container':
var copiedElem = $('#containerItemTmplt').clone(true).
.attr('id', 'paneI1')
.appendTo('#container');
This works great and i confirm using I.E. 9's developer's tool utility that the element was indeed added with the correct id as a child of 'container'.
However in my test method, when i inspect the element that was copied, the id attribute is an empty string:
function test(elem)
{
var parentItem= $(elem).closest('div')[0];
alert(parentItem.id); //<--this displays an empty string despite

I am generating HTML based on user actions (in this case, populating a table with the result from AJAX calls).
In my context, I have a link where there is a Quantity field, which I would like to be editable. When I create the html, I give a unique ID to each row, (to reference to a JSON object), however I am unable to get the ID for said row, seeing as the DOM tree is parsed on the pageload and doesn't seem to update when I add elements to the page.
This means that $(this).parent('tr').attr('id') is not returning anything at all.
How would I make it so I can retrieve the ID of my row (which was created/added to the page after it was parsed)?

I am selecting an image as part of a html form. Once selected, jQuery assigns a user-defined attribute of the image to a hidden form variable and passes it to form handler. Problem is when I dynamically add images that can be selected. I am using live function to ensure that the dynamically added image is highlighted when clicked - but the user-defined attribute is not being grabbed by jQuery.
I think that when the page is first loaded, all the existing image attributes are loaded into the DOM, but when extra images are added with ajax, the DOM doesn't have the new attribute values, despite them appearing in the html on the page. I don't think I can use the live function in this instance, because an attribute is not an event. Out of ideas now. HTML/PHP, with jQuery:

I've got a database written in MySQL with a bunch of PHP interfacing with it. What I want to do is populate drop down menus on a form from this database.
The way I went around solving my problem is as follows.
Code:
Which calls the function from the search.js file, which performs the following operation:
Code:
With element2 being the appropriate preemtied dropdown box, and addOption defined as follows:
Code:
So far so good. This works and produces the correct list of elements in the first dropdown box if the first dropdown box is the target. Here is where things begin to go wrong: On this form I have an add more elements button which is defined as follows:
Code:
And addElement being defined as such:
Code:
While this does successfully create all the cells I want it to create, when I attempt to select Country from the resulting dropdown, I get an empty drop down wit only the "Search For" present in it.
Firebug then proceeds to flag array in selectorfunc above:
Code:
What i believe is going on is that for SOME reason the newly created drop downs aren't being passed js_countries correctly. Unfortunately I don't know how to fix it.

When the user select an option in a dropdownlist, new dropdownlist elements are added dynamically using jquery. When a user clicks on a new option i the first dropdown, I want all the dynamically added events to be removed so that I can render new ones. But it seems the dynamically added events haven't been added to the DOM, so they cannot be removed. Is it possible to remove them? In that case, how? I've read a lot about .Live(), but my problem is not regarding an event - I just need to reach an element(?).
