Referencing Other Page's Dom
Aug 28, 2007
Is there a way in the Javascript to reference the dom of another page that is online. An example would be if www.cnet.com has an element with an id = money can I reference that page with an object that and get a value from the money element and display it on my page. I know this sounds confusing but really i just want to be able to save a xhtml page that is not on my website. Create a input filestream from that page and use data from the filestream to make data on my own page.

I coded the following JavaScript:
var el = document.createElement("iframe");
el.setAttribute('id', 'ifrm');
document.body.appendChild(el);
el.setAttribute('height', 250);
[Code].....
And am putting it between <script type="text/javascript"> and </script> tags in the <body> section of my site. But, it only works in certain areas of the page.

I'm trying to get a value from a link that a user click on in a pop up window and send it back to the parent window. It's working fine in mozilla and some IE but i'm having problem in IE 5 and some IE 6.
<a href="javascript:opener.document.getElementById('<?php echo $_REQUEST[partid];?>_partremoved').value = '<?php echo $partnum;?>'
opener.document.getElementById('<?php echo $_REQUEST[partid];?>_partinstalled').value = '<?php echo $partnum;?>'window.close();">
<?php echo $partnum;?></a>

whenever I run the below code I am unable to hide my <DIV>. I have posted a previous post regarding hiding DIVs however as this is slightly different I thought I would create a new topic here to allow for easier searching for other users.
The below code works if the DIV is outside of the form however if I enter it within the form nothing happens.
<form name="formcreate" method="post" action="">
<table width="80%" border="0" cellspacing="2" cellpadding="2">
<div id="div1">
<tr>

A have an array of objects defined like this:
var collegas =
[{smtp:'alberic.verhelst@king.dom',voornaam:'Alberi c',famnaam:'Verhelst'},
{smtp:'anita.dierens@king.dom',voornaam:'Anita',fa mnaam:'Dierens'}, etc
I iterate over this array with this code :
for (var i = 0, stop=collegas.length ; i < stop ; i++) {
for (var veld in collegas[i]) {
etc
I would like to check whether a particular veld instance's name is smtp. In
code what I want is this :
if (veld.fieldName=="smtp") { do something ...
But this syntax doesn't work.....

I would like to reference the "name=value" parameters sent to my page
(submit'ted from a previous page with a <form>.) in my javascript.
I can do it if my second form is called with a "get" using the
window.location.search property, etc.
I don't know where these parameters are if my second page is called with a
"post"...

I am loading a set of icons using an array. The reason for this is that the icon set will be different depending on what some PHP code has given to the JavaScript.
My code currently looks like this.
Code:
var things_to_load = new Array();
things_to_load['header_cursors'] = new Array( 'default' , 'pointer' );
things_to_load['header_icons'] = new Array( '../img/triggers/to-roll/undo.png' , '../img/triggers/add.png' );
things_to_load['header_labels'] = new Array( 'undo' , 'add' );
[Code].....
The problem I have is that the click function gives the error "things_to_load.header_clicks[c] is not a function".
This makes sense as presumably the click function is saving the value and not what that value references.
how I can get this code to save the function not the string referencing it?

i have a simple thing that causes me all sorts of headaches. I have many forms on the same page, and identical items in each form. The same object in each form call the same procedure. So, I'm passing in the form value, such as:
onchange="DoMyFunction('formName');"
and then in the procedure i do:
function DoMyFunction(formname){
document.[formname].object.value='1';
}
Now i have functions like this all over, problem is getting them to work. Once they work, they work fine. But when i add a new one, it can match an old function (except the object being referenced) and it won't work!
Does anyone know the proper way to reference a form in a function?

My functions for mouse_move / up / down all control the movement of a box. So you can click a box and move it anyway. It then snaps to an invisible grid. However there are multiple boxes on the screen so if you move it to a spot where another box already resides, then that box needs to swap places.This is what the mouse_over function tries to do. When I click the first box it stores the position of that box that was clicked. If I release the mouse button whilst hoovering over another box I want the other box to take the stored positions of the first box.However what I think is happening is the mouseover function is applying the new position to the box I'm moving, as I guess this is the first layer the mouse is over.Is there anyway I can reference the layer underneath using onmouseover.
<script language="javascript">
var x;
var y;

I have a table which I would like to be highlighted with the click of a button, but I can't seem to reference it correctly. I can make the <td> clickable and function, but when I try to apply it to the button I can't make it reference the td cell, rather than change the background color of the button.The function is:
function roll(obj){
obj.style.backgroundColor == "pink" ? obj.style.backgroundColor = "#e5e5e5" :
obj.style.backgroundColor = "pink";
[code]....

for(x = 1; x < totalCheckBoxes; x++) {
checkBoxName = "document.addProductEditor.journalEdit_" + x;
if(checkBoxName.checked == "true") {
//updatedJournalList = checkBoxName.value + ",";
}}
The problem is that while checkBoxName produces the correct variable, the final if statement claims that checkBoxName.checked has no properties. What am I doing wrong?

I am trying to return a JSON string from a server with a list of locations. I want to populate a div with checkboxes and the names of the locations.This is the JSON string I am currently working with:
Code:
[{"loccode":2,"locdesc":"Atlanta"},
{"loccode":1,"locdesc":"Charlotte"},
{"loccode":0,"locdesc":"NA"},
{"loccode":3,"locdesc":"Test1A"}]
I have a similarly formed data definition that is hard coded in the javascript for permissions that looks like this:
Code:
var prm = [
{"id":110,"idtext":"110","prmdesc":"Users"},
{"id":130,"idtext":"130","prmdesc":"Forms"},
[code]....
When i run that bit of code it displays Test1A and that is all.I am certain I am missing something basic, but I have not been able to figure out what it is.

I've written several utility pages that use a dynamically created
iframe. The iframe typically has a form that is populated by the main
page. Then the form is submitted to be processed, and the returning
page does something -- call a function on the main page, change a
variable on the main page, etc.
All this stuff I created works on IE. Sorry, didn't have other browsers
available to test. Now I have access to a machine with FF, and none of
these scripts work.
So, short and sweet: What is the proper way to reference a form on an
iframe from the parent doc in firefox? Also, call a function from the
parent to the iframe, and vice-versa, call a function on the parent doc
from the iframe when it loads?

I have created an object called list. the object has a method called load and a method called setSelected (it has more, but they arn't impotant here).
The load method prints out table rows like this:
str+="<tr>"+data+"</tr>";
and in the end, inserting str as the body of a table.
what I want to do now, is have an onclick event for each of these table rows, that calls the setSelected method of the current object. so for example, if I'd write this on my page:
mylist = new list(args...);
mylist.load();
<div id='associated-div'></div>
that if someone clicks a row in the table that is created in the div, the setSelected method of my list oject will be called.

I am using the following system to create my forms : <% using (Html.BeginForm()) { %> Now I want to refer to the form in JQuery, but all the examples I can find refer to the form by it's name. How do I refer to my form if it doesn't have a name?

I have this function:
Code:
$(function () {
$('#Tags').tagSuggest({
separator: ", ",
[code]....
This references the #Tags element which is an input text box. I would like this function to run on another element also (#Tags2). So if either the #Tags or #Tags2 text boxes are used, the function runs.How can I extend this function rather than duplicating it?

I have a script which works from my main page, but I need to embed it also into an iframed page, and have it affect the main page from there as well. In my main page, I have the following iframes:
<iframe id="main">
<iframe id="player">
<control buttons embedded on main page, along with the iframes>
The default source of "main" is page A, which is a frameset of pages B and C. In page B, I want to embed the same controls I have on the main page, and have them affect the main page from there.
Here's the controls script from the main page - it works from that page - a resizing onClick of the "player" iframe:
<head>
<script language="JavaScript">
function resizeIframe(iframeId, iframeHeight, iframeWidth)
{
if (iframeWidth>0)
{
document.getElementById(iframeId).style.width=iframeWidth;
}
if (iframeHeight>0)
{
document.getElementById(iframeId).style.height=iframeHeight;
}
}
</script>
</head>
<body>
<a id="widenButton" onclick="resizeIframe(player', 420, 720)return false;">Enlarge Player</a>
</body>
How would I put the widenButton in that back page and still have it affect the front page?

What I'm trying to do here is even possible.
I've tried numerous variations of the alert line with evals, brackets and jQuery syntax but always seem to get the error:
XML filter is applied to non-XML value ({one:["1", "2", "3"], two:["a", "b", "c"]})
Which makes me think I'm either attempting something stupid or only missing my target slightly.
The code will be running within a jQuery project up if that helps in any way.

I have managed to write a working script to add together two values and display the total. I need to advance from that stage and now I have a 'quantity' box and a drop-down menu with a few options on it, each relating to a price. I am trying to take the quantity entered by the user and multiply it by the price they select from the drop-down and display it in a third box. So far I have:
two = document.autoSumForm.value from menu.value;
document.autoSumForm.total.value = (one * 1) + (two * 1);
How can I rewrite the above to account for the different choices a user can make on a drop-down menu?

I'm trying to build a page that shows random, alternating divs, and have looked at this page as an example. However, the issue at the moment is that although the divs display randomly, they do not disappear in order.The finished "page" is to be referenced by another page that I do not have control over. Here is the section of the file containing JavaScript:
<script type="text/javascript">
var curcontentindex=0
var messages=new Array()
[code]....
I've found very little info on how to reference a previous variable...maybe create an array to store them in, but wasn't sure how to go to the previous value in the array.

I have groups of elements that are scattered around my page but have identical id's so that I can reference them all at once (as a group).These elements are sitting inside of an iFrame, that is sitting inside another iFrame (that is building a nested navigation bar).So what I want to do is have a script sitting in the top document that when a button is pressed it will reference those double-nested identical id's and toggle their display.and this is what I have so far...(while testing, I do not have any identical id's)
HTML Code:
<!-- my buttons -->
<form>

I'm writing a JS script that will be available as open source. This script needs some accompanying image files. I have been planning to package the .js and the image files together in a single directory and let the user put that directory anywhere they want. Trouble is, I can't figure out how to write JS code to put a reference to these image files into the html. The image files are relative to the .js file, but I haven't seen anyway to figure out the path to the .js file (i.e. the path to the code I am now running). Is there a way? If not, how do people usually package up a .js file and some accompanying image files?
