Scripting Between HTML And SVG?
Mar 5, 2010
I'm working on a project using JQuery and Keith Woods' extension to provide SVG functionality. My final goal is to develop some kind of HMI/SCADA implementation. My intention is to have an svg graphic representing some kind of process and then change certain shapes parameters from scripting part.
I'm pretty new to Javascript, JQuery and so on. But I'm trying to make my way by reading a lot on internet. However I couldn't find a clue about my most recent issue.
Mi idea is to embed and svg file created before on Inkspace. This would be the skeleton of the process I want to represent. Then, from the html document where this svg file is embedded, I want to alter certain parameters of the shapes inside, for instance I want to change the colour of a particular rectangle.
So, I embed the file in the html document like this:

<td onMouseOver="foo(event,this,'string');">something</td>
It works fine i.e. the event handler function foo is fired with the
event parameter containing the event. I do the cross-browser thing to
handle the event parameter
var evt = (evt) ? evt : ((window.event) ? event : null);
and I am all set
But when I try to do the same thing by scripting i.e. get the TD node
via the DOM and add in the event handler like so
var td=document.getElementById('tdid')
td.onmouseover=function() {
foo(event,this,"string");
|
It works in IE, but in Firefox (1.x), I get an error in the JS console
"event is not defined".
Why is this? Any way to get consistent, cross-browser behaviour?

I'm trying to set up a system similar to Google AdSense that allows other websites to display some HTML content from my site on theirs. I've looked at the show_ads.js file Google uses to display Ads but to be honest I've not found it easy to decipher. I've also read that using a <script> tag to load a JavaScript file from my site is simpler than trying to do do this with an AJAX request. it discusses returning JSON rather than HTML.
BTW I know I could use an iframe to achieve something similar but this won't give me the result I need because the content coming from my site will contain a link back to my site and I want the link to be registered as an inbound link to my site for SEO reasons.

If I have a list inside a <div> is there anyway to add another. Example:
<div name=test>
<ul>one</ul>
<ul>two</ul>
</div>
Now later on if the user clicks a button can I add:
<ul>whatever the user typed in</ul> after "<ul>two</ul>" <-- note this is not php

I've a personal application I would like to script, that would
bring up a particular web page (which happens to have a Flash application
on it), then every 15 minutes or so generate the equivalent of
clicking on a button (causing the application to retrieve and display
the latest info).
Anyone know of any articles or howtos on the web for writing such an
application? Code:

I am remote scripting using javascript to an XML gateway, the XML file I get back changes state i.e. either the car registration number exists (and it includes certain fields in the XML) or it doesn't exist (and it doesn't include certain fields).
When my code tries to display the result I am getting the 'object required' error because I am trying to access an xml element which doesn't exist.
For example this line would break if the plate didnt exist but work perfectly if it did:
var fuel = response.getElementsByTagName('Fuel')[0].firstChild.data;
Is there anyway to stop it throwing an error if it doesn't exist and just set a regDoesntExist flag or something?

I'm a greenhorn in SVG and javascripting but I'm learning by doing.
So, here my current problem question :
I have a svg document embedded in another svg document. I whant,
through functions in an external javascript file, manipulate objects
in either the child svg document or the parent document.
How do I get access to elements of the other document ?
Example : I have a document "A" containing X/Y - Axis and included
another svg document "B" with the graphs.
I whant now, as soon as the mouse cursor is over a graph in document
"B" the belonging lable which is located in the parent svg document
"A" to change color or size.
Or I whant the graph in "B" to start blinking as soon as the mouse is
over the lable in "A".
I don't know how cross document borders.
Can anyone give me a short exapmle to get me going?

I have some doubts about this meta tag:
<META http-equiv="Content-Script-Type" content="text/javascript">
Do I really need to declare this meta tag in all my pages?
If I declare it, will I still need to create my scripts this way?
<script type='text/javascript'>
Is there any advantage/disadvantage when using it?

is it possible to have a script that waits until the Adense javascript is done selecting ads, and then uses that data to do something.
for instance, the script checks if "Laptop" exisits in the link text of an adsense ad, and then proceeds by downloading (XML-RCP?) a picture of a laptop from the server.
It's important that the code does not interfere with the adsense script itself because that violates their TOS, but is it possible to just "read" the data that it generates?

I'm wondering about a very strange behaviour in a javascript: In my
web application, there are a few SVGs (Adobe SVGViewer 3.0) embedded
by OBJECT-tag in an HTML-File. By starting a (globally known)
JS-Function in the "Menu"-SVG, it creates a new SVG-Node-Tree and
appends it to a anchor-Node in an "Display"-SVG. This means, a
function called in one document creates SVG-Eelements in another
document. This works fine, if a simple JS-alert is included at the
beginning of the SVG-creation-process. If not, it doesn't work - no
SVG is created. IMHO, i can exclude a runtime error, for that i
analyzed it quite intensive. In my opinion, the problem could deal
with restrictions on scripting over document borders. Nevertheless, i
don't understand it. Does anybody have experience with that kind of
behaviour? Does an alert have such influence on something like a
"focus" on a document?

Is it possible to run an HTML file from "localhost" and bypass the
various security checks in place for cross-frame scripting? For
example, on a 2-frame page loaded locally:
a) frame 1 includes a form that accepts the name of a web site
(example: www.foo.com), which a script or perhaps a "target" attribute
then loads into frame 2
b) frame 1 waits for frame 2 to load, then reads (for example)
top.frame2.document.images.length and displays the total in frame 1
I realize that "localhost" is not going to match the domain appearing
in frame 2, but as I myself am running the script, logically, where is
the harm?
I haven't done much testing with this yet, but am planning an
application around this concept and am hoping I can make it work. Any
pointers?

I need to html encode all text field values on the client just before
sending them to the server. A javascript equilalent of Server.HTMLEncode in
IIS. I also need to be able to perform the reverse.
All I am trying to do is ensure that if a user enters html tags in the a
form, that the tags does not get parsed by the browser.

just learning javascript and DOM. i'm writing a form creation system. this code works in FF 1.5 but not in a default configuration of IE 6 on WinXP SP2. i'd appreciate any help getting this to work in IE.
what i'm attempting here is to create a module (in this case one with a text area) using the DOM and this module itself has controls that make use of the DOM (example code is a delete module button). in IE i first "Allow Blocked Content..." via the information bar. after this the module creation button works fine but the buttons that are part of the module do nothing.

I have a javascript function for DOM scripting Its a search with certain Nodes which by Default is checked upon clicking the submit button it shows results in a diff table
The problem is that it works perfectly fine in Mozilla ,Firefox but Not Internet Explorer. The check boxes next to the Nodenames are not checked and the search does not display the results in a table. however it works perfectly fine in
Mozilla browser. In IE it shows an error with 'a object required' for checked boxes . As i think, It s coming from the save search option function, i am not sure if i have to create another object for calling the .checked operation in the search table Code:

I'm not sure why my ajax is throwing a cross site scripting error. I have a php page that request a page not in my domain. I have another page where my ajax requests the php page, which is in my domain. Then the error is thrown. Since the php page is in my domain, why would the error be thrown?

Currently my code looks like this.

I'm working on a project at the office that pulls together a bunch of
our websites into a portal thing and adds a better search engine. We're
also trying to accomadate newer browsers (Netscape 7.2, Firefox,
Safari) and are having some problems. The websites run on different
servers, all of which we control, so we are setting the document.domain
= "ourdomain.com"; in some javascript on ever page. However, we're
having problems. We use popup windows for some things, and sometimes
these popups want to 'populate' the parent frame window with a new page
as a result of a user selection on the popup.
This works most of the
time, but not always. For instance, in Netscape 7.2 it just seems to
fail with an "access denied..." error in javascript. In Firefox and
Safari it opens a new window and populates that instead of populating
the original parent window. Can anyone point me at some definitive
information about the document.domain property and how to use it
effectively?
