Since XMLHTTP Request does not support loading of XML from other
servers, I decided to use a trick:
load XML into hidden iframe and then get that XML with JavaScript to
parse.
But, is this a good idea? I am stuck. How do I get XML loaded in the
iframe and pass it on to JS function for parsing?
I want to load a javascript file on a root page with various iframes,
then call the javascript functions from the root page to be displayed
in the iframes. Any idea how to do this?
I have a webpage with some divs and iframes in them, I have some Javascript code in another page in one of the iframes that when activated, will change the page within the other iframe. The code I have throws the following error:
'null' is null or not an object
and it is complaning abou the following bit of code:
var obj = document.getElementById("frame2");
obj.src = new_src;
But I am not sure if the code is the correct code anyway. Can anyone assist please?
Please find below my complete code, hopefully you can spot what's going on. Here is my 'index.htm' file: Code:
I'm starting to use some iframes in a div layer. I want to know if i can use javascript to change the size of the iframe (from the parent page containing the iframe).
In IE i can use 100% width and height to fit the iframe to the layer, but in Netscape 6 the iframe doesn't appear if the height is set in % values - hence the need to be able to specify it dynamically as the layer wil change size.
I have bigpage.html that has the text "click" in it. Also, it contains the iframe small.html.
In small.html there is the text "visible"
How do you get it so that when you click on "click", "visible" changes from black(default) to red?
is there a way to create iframes using cookies and javascript? What i need to do is to have a way to create a cookie on page one, and use the info on page two to create the iframe.Users will see a list of "external links", once they click on a link, they will be redirected to a page that will generate a iframe of the chosen link.My guess is that if there is a way, it must need to use cookies to store the info (url) to get used by the script that will create the iframe on the page that will be used to show all iframes.

But if they make pages without javascript, they would not need to bother, how to access other frame's content, would they?
First the code:
Code:
Looking at the code, you might assume (as I did) that clicking the button on page1.htm would load page2.htm. However for some reason, when calling a parent function, the function runs with the calling file's path rather than the path of the parent.
So it is actually trying to load /files/files/page2.htm! How do I force all calls to parent.function() to run with parent.hta's path as the root?
Realize that this is a simplistic example and simple solutions such as putting all the files in the same path, or dropping the "/files" in the loadPage2() function are not valid solutions.
Essentially I need to call parent.loadPage2() and have it run the function with the root path = parent.hta's path.
My problem is that i need an algorithm parse parse HTML.
For an HTML page, my script has to parse all tags to get all forms
values, even if there is frame, iframe, ...
How can i do such a script ?
I have an XML file that among other things has the following node.
As you can see it contains HTML tags.
<description lang="en">
<![CDATA[
<div class="descrBoxRight" style=" top:250; left:200">
ENGLISH <b>ENGLISH</bENGLISH ENGLISH
</div>
]]>
</description>
With javascript, in Mozilla, I easily retrieve the content of the
XML "description" tag using the following line of code
var myStuff = myDescrNode.textContent;
However, in IE (6.0)
var myHTML = myDescrNode.textContent;
and
var myHTML = myDescrNode.innerText;
do not work, resulting in myHTML being undefined.
Alternative solutions? Should I remove the CDATA tag
and use a completely different method?
I have a web page that I created that should basically do the following:
Parse an xml feed with javascript and display the contents to the page.
The problem is as follows:
I can parse the feed and display it using javascript but it only works for internet explorer. For some reason when I try doing it in firefox, it doesnt do anything and nothing displays.
I think it might have to do with the fact that it is loaded from url.
Any comments?
Hi, I'm fairly new to AJAX, but I've been able to retrieve HTML and plain-text documents without any trouble. However, I haven't figured out how to retrieve it in XML format. Basically, here's the script that's supposed to retrieve and parse the data when you pass it the url of the page generating the XML data:
View 1 Replies View RelatedI'm trying to use it to load in an XML file and output some data. I followed a tutorial on it but my XML file isn't loading.[code]Now my thinking is that when the document loads, it alerts me that the jQuery is running, and it does this. I had hoped that after closing that alert, another one would show saying that the XML file has loaded - This would ensure that the function 'parseXML' has been called, but it does not return an alert or populate my#xml_addressbook div.My index page is at the root, and both my XML file and the javascript file are in a folder, as shown below.[code]
View 10 Replies View RelatedI'm building an application with a c#.net server and a good bit of jquery on the front end. I'm having trouble getting/parsing data from c#. In the C#, I am doing a db call to pull the information for all users, and putting it into xml format:
string xml = "<?xml version='1.0' encoding='utf-8' ?>";
xml += "<Users>";
while (res.Read())
{
[Code].....
When I run the application, I'm getting the 'in AjaxSucceeded [object XMLDocument]' alert, but I cannot get inside of the 'each' loop.
I'm currently working on a pretty straight-forward AJAX application. In this application, I get some XML, and then parse it. An example of what I'm working with is as such:
<?xml version="1.0"?>
<postRoot xml:lang="EN">
<post type="comment" date="January 1, 1970">
<user>athlon32</user>
<content>Hello World</content>
</post>
</postRoot>
Now, I've been able to read the XML with XMLHttpRequest , my trouble is with parsing the results. I've tried tons of things, but I just can't seem to get the different child nodes. Now, let's say we have something like this:
var xml = xhr.responseXML;
var allPosts = xml.getElementsByTagName('post');
Could I use childNode to access user & content? And if so, how? I've tried many things, but nothing is working :/ Is there a better way to parse the results I get back from the server?
For a project I am working on, I need to retrieve links from html
documents. The easy part is to obtain 'plain' links like <A
HREF="http://site/path/document">, but when those links are
javascript'ized, the only robust solution needs to load the javascript
and dom document representation in the same way that browsers do. For
example, links in the form:
<A HREF="javascript:function_declared_before("arguments"));>
First I though that using spidermonkey (the mozilla javascript
interpreter) should be enough, but in that case, I dont have the
document structure elements (like document, window, document.history,
document.form.element, etc), so I tried parsing the document using a
library to build a tree representation of it, but that leads me to the
same problem again, that is, I have to represent all tree nodes as
javascript entities.
Anybody here have worked on a similar problem? What tools do you
think I should take a look?
I'm writing a program on Zimki, which I think uses SpiderMonkey as a server side Javascript engine.
My idea is to have an html file that someone else created, and look inside for cells in a table that have special known names, like name, description, etc. Then I want to figure out the <tr<tr/pair that encloses all of those special tags, and use that as a template to generate a bigger table from another datasource.
So, I'm wondering how I actually open a file and then parse it as html so I can poke around the DOM, all from the server side without involving a browser client.
I am trying to write a script which will allow me to read the contents of an
HTTP web page into memory, parse the data, and output a calculated value.
The HTTP page is on a web enable appliance - I am reading some data out of a
table for further calculation. I can't modify the web appliance, only read
the text data.
I've written a script on my Windoze PC that successful uses a MSXML2 ActiveX
object to read the contents of a web page into memory using the
xmlhttp.responseText object. The problem is that the ActiveX object is not
available on a lightweight Linux based http server.
I need to write a script that will work with ASP/Javascript on a lightweight
Linux based http server.
When I try to parse xml fixed string following code works fine. When I try to parse the string get from remote server.(bellow code example) It gives me an error unterminated string. I think this error is because of large string. Code:

Maybe it isn't really best practice (as it turns out) to use both jQuery and Dojo in the same application, but there are things I like about both libraries (for example jQuery is faster with animations, while Dojo has interface objects I like better). Nonetheless, best practice or not, I use both and that seem to create some complications.
The first time I load content via AJAX with jQuery DOJO seems to properly parse the checkboxes, datetime pickers, etc. which are sent with the new HTML. However, it seems the second time the parser won't react. I'm calling dojo.parser.parse() every time I load content with jQuery's $.ajax call. So basically my code looks like this:
Code:
$.ajax({
url: 'ajax.php',
success: function(data){
[code]....
It's like when an ID has been treated once by Dojo it doesn't want to do it again. there's a way to let Dojo know it has to parse the same IDs again?
Through an AJAX implementation, I am receiving a SQL Query result that has:An object's attribute delimited by a comma.An entire object (database row) delimited by a colon.This is an example response to make it more clear for you.
1,Jeremy,130,80;2,Lauren,370,300;3,Jeancarlos,200,200;4,Luke,330,70;5,Bloom,392,108;
What I am trying to achieve is placing all of this data into an array. I've set up a little test bed to try and get this to work; this is all I have so far:
var testString = "1,Jeremy,130,80;2,Lauren,370,300;3,Jeancarlos,200,200;4,Luke,330,70;5,Bloom,392,108";
var testArray = new Array();
testArray = testString.split(";");[code]....
get a multi-dimensional array that has information for each person. Example:
FinalArray[0][0] = 1
FinalArray[0][1] = Jeremy
FinalArray[0][2] = 130
I want to use ajax to submit a dynamic form which can be filled with infinite elements. The only problem is passing all of the values of those elements through the ajax and onto my jsp page where they will be processed.
Code:
"promptIds=" + document.getElementsByName("promptId")
That is one of the arrays that I send and I am using jsp, but in any case, how would I parse the array to be usable?
Code:
String promptIds = request.getParameter("promptIds"); System.out.println(promptIds);
The above code outputs "[object HTMLCollection]". How would I go about parsing the array of elements?
I am trying out $.ajax instead of getJSON for debugging purposes. Because getJSON did not report an error in IE (6,7 or 8) and I am
trying to figure out why a jQuery plug-in is not painting my returned images to the screen in IE but is in other browsers. So I tried this. Interestingly enough, it hits the error event in IE but not firefox, safari and the rest and I don't know why (this code works great and renders my data just fine in FireFox and the rest). I know my returned json is valid:
$.ajax({
type: "GET",
url: "http://localhost:59396/sss/sssHandler.ashx?
action=getproducts&ids=" + ids,
[code]....
I don't know what else to do to troubleshoot why IE is having so much trouble with the returned JSON or just executing the function(data)
using either getJSON OR this. I have set the headers not the cache also in the response. IE refuses to enter my function(data) on the response.
[
{
"ImageTag": "u003cdiv class="CarouselItem
"u003e<p><img src="http://www.xxx.com/image/
[code]....
Same result. Firefox and the rest had no issue. IE still exited the $.ajax and my error method kicked in. No rhyme or reason whatsoever and I tried the IE Dev tools... nothing. About the only thing I get is this: Line: 163 Error: System error: -1072896658.Line 163 which is simply the line: function() { alert("An error has occurred. try again."); This has got to be the most f*d up situation I've been in and I need to get this working! I just cannot understand why IE can't parse a getJSON or $.ajax response, that is impossible or else there would be a huge meltdown with jQuery.
In the Yahoo! UI event.js file I see the following quite a bit
for (var i=0,len=unloadListeners.length; i<len; ++i) {
when I always just write
for (var i=0; i<unloadListeners.length; ++i) {
Is it worth it to declare the variable len to save time evaluating
unloadListeners.length?
Does anyone know why IE7 is refusing to do 'the trick'?
It works nice in modern browsers and even in IE6 [url]...
