I'm trying to create a function that will return the value of responseXML so I can assign a variable to it.
Code:
ajax.downloadXml = function (url)
{
var XMLHttpRequestObject = false;
[code]....
Stepping through the function, the onreadystatechange seems to never be executed, so nothing is returned. There's probably just a fundamental I'm messing up on.
how to assign a value to a global variable within a function and can't seem to figure it out. Here's my thought,
<script type="text/javascript">
var global1=""; var global2="";
function assign(vari,strng){
[Code]....
The purpose behind this is creating a form that will work with an existing database that would normally have a text area with lots of information. I am trying to turn it into a checklist that I can run from a mobile device. The global variables woudl be used to fill in a hidden text area that would then be passed on to the database upon submission. I am trying to keep the code as compact as possible.
I am trying to assign a variable to a jquery object that is found using the children() and eq() methods. This is a simplified version of the html structure.[code]Here is the jquery code. All I want to do is assign an object to the variable and be able to manipulate the object through the variable. [code]Again this is a simplified version of my code but the structure is similar.
View 2 Replies View RelatedI've got a piece of code where, for all the world, it looks like this fails in IE 6:
hometab = document.getElementById('hometab');
but this succeeds:
hometabemt = document.getElementById('hometab');
Has anyone ever seen anything like this before, or am I dreaming?
In processing the response from an AJAX call, assume the returned xml string as:
"<?xml version="1.0" encoding="UTF-8"?>
<options>
<option text="new search..." value="search..."/>[code].....
Now, in the javascript:
1)If I use ajaxRequest.responseXML, I can directly use it as DOM document, such as: ajaxRequest.responseXML.getElemetnByTagName("option");
2) Or, I can use another way(assume on Firefox):
var parser=new DOMParser();
doc=parser.parseFromString(ajaxRequest.responseText,"text/xml");
doc.getElemetnByTagName("option");
My questions are.Since I can use ajaxRequest.responseXML.getElemetnByTagName("option") directly, I do not need DOMParser to convert.On the other hand, if the ajaxRequest.responseText is NOT of the XML format, the parser.parseFromString will not work any way.Then, why (under what circumstance) should one use DOMParser?
I'm having trouble figuring out what's going on with IE6's
Msxml2.XMLHTTP object. I have two feed addresses in this stripped down
version of my code below. Both work fine in Firefox (using the
XMLHttpRequest object), but only the thinkgeek one works in IE. In the
processFeed function, it shows the problem - the first alert shows 0
for the wikihow feed in IE, though it can still display the
responseText. Any insight? Code:
I'm not getting any response for the following ajax request. I'm getting the following error when i try to run request_get_xml.html im mozilla firefox:

I am trying to build a very simple Ajax example with JavaScript and PHP. Basically, the goal is to populate a select list with values dependent on the selection in another list. I am able to do a GET from a server-side script and I see the XML displayed correctly in XMLHttpRequest.responseText. However, when I try to check XMLHttpRequest.responseXML, I am not able to get anything out of it. The alert() shows it as an "Object", so it's not null. I have tried getElementByTagName() from both responseXML and responseXML.documentElement, each time giving a legitimate inner tag, but nothing comes out. What is the correct way of doing it? This is my JavaScript and HTML code:
[Code]...
I tried POSTing from XMLHttpRequest, i can get the XML right on server
but responseXML from server is coming null. I can see the XML right in
responseText. but responseXML is null. responseText to DOM conversion
also fails while the XML in responseText seems valid ..
-- here is the javascript code for sending ---
I have several functions with code along the lines of:
var xmlDoc = requestXML("ajax.asp?SP=SelectRelatedTags&tag=" +
array[i]);
The requestXML() function includes the code:
var xmlDoc = null;
http_request.onreadystatechange = function() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
xmlDoc = http_request.responseXML;
} else {
alert('There was a problem with the request.' +
http_request.status);
}}};
http_request.open('GET', url, true);
http_request.send(null);
return xmlDoc;
However, the last line (the return) executes before the readyState
reaches 4. How do I return the xmlDoc to the functions only once the
xmlDoc has been assigned? I tried putting the return statement in a
while loop with the condition that the readyState must = 4 - this
worked, but makes the browser popup a message saying the script is
slowing down the system.
The situation is; I receive a response back from the server which i only a part of html code. e.g. a table like <table <tr><td>high</td></tr>........ </table>. In other words, I receive
file as a response which has a part of html file.
My aim is to replace an existing document node with the new response.
If I run the following lines (JavaScript):
var parsedText = document.createTextNode(req.responseText);
body.replaceChild(parsedText, toReplace)
It replaces the node 'toReplace' with html codes with the tags include which is not what I want. The html tags are not wanted but should display in correct format as specified by html (a tabular form if htm tag is <table>)
If I try:
My code gives me an error only the first time when i press the checkbox. If i press it for the second time or just to uncheck the checkbox and it gives me the right answer.I use IE7, xampp with appache server and Windows7.

Im developing a JSP site... my user information validation page is not working and its giving that responseXML object is null...Im not using any XML file to fill the data here.... all the messages custom messages are loaded from the JSP page....My Valildation.js file as below.....
// holds an instance of XMLHttpRequest
var xmlHttp = createXmlHttpRequestObject();
// holds the remote server address[code].....
I have tried debugging using the alert function and have come to the conclusion that the responseXML property keeps returning null even though I have set everything correctly.
Here is the source code:
HTML Code:
var gE = function(s){return document.getElementById(s);};
var foo = gE("foo");
work, while
var gE = document.getElementById;
var foo = gE("foo");
does not?
When i assign some css properties should i allways use the postfix like
measurment units (so use: 150px instead of only 150).
Any neat way to copy a snapshot of one array to another?
A normal assignment results in the second array pointing to the first,
with changes to either array affecting both.
As a trivial example:
var a=new Array();
a[0]="zero";
var b=a;
b[1]="one";
alert("a="+a.join("*")+String.fromCharCode(10)+"b="+b.join("*"));
.... this results in a and b being identical two-element arrays.
Is there any easy way to set array (b) to be a copy of (a) BY VALUE -
ie using the contents of (a) as they were at the moment of assignment,
but leaving the two arrays separate so that subsequent changes to one
array does not affect the other?
I have an index.htm page ready. I want to be able to put in javascript code into the HTML coding that will write the ip address of the actual server that is hosting the website into a hidden text box. Then I want to insert this ip address into a hyperlink in the original index.htm to link to another html page (this will be a SSL secure page instead i.e. [URL].Also vice versa. (With SSL index.htm page have code that writes ip into hidden text box then hyperlink to the original http index page)
View 7 Replies View RelatedI have the html contents from an iframe stored in a mysql data record. I now want to load that back into the iframe. I can assign the php var to a js var using PHP Code:
var scontent='<? echo ($html) ?>'
but the string has been saved to the db with newline chars in it and is causing a js error because it is being interpreted as an un-terminated string:
var scontent='<P>This is a test</P>

It didn't work. I was wondering if there was a way of assigning multiple lines to a js var. any ideas?
I am creating a tool to merge xml files using xslt usin
Javascript/HTML.
Basically the user browses (browse button) to where there xml file
are, then browses to where their xslt file (to perform an operation
is. Then they click an "apply" button and the result is output in
frame below.
My problem:
I have the tool working fine when I only have one input xml file (whic
is no good in a merge tool!!) but when I modify the code and ad
another xml field, the apply button will not work for two fields!
I think I haven't assigned the functions correctly to the xm
fields/apply button. Heres some of the code I suspect is wrong, but i
not sure where?? Code:
3-level dropdown box: [URL]. Now in this dropdown menu if you select:
Category > Cars
Sub category Cars for Sale
Sub Sub Category Ibiza
What I want to do is two things:
1)Place a value on all the Sub Sub Category(ies) so for example the value of Ibiza I want to = 55
2)Then Grab that value? How would I get that value and grab it from POST?
I am barely familiar with javascript. I have this html code with an embedded iframe. The html file in the iframe refreshes every once in a while. That is fine. However, in IE, there is this annoying click with every refresh. I googled a bit and saw a few solutions. Seem to me that if I fetched the contents of the HTML file (AJAX call) and assigned it to existing document.
1. How do I assign an entire document in JS?
2. If I did this would this prevent the clicks?
I have a situation where I'm trying to assign a value to an elements innerHTML. When I do this, the value is assigned, but it causes havoc on subsequent javascript calls.I realize this is kind of vague but I'm at my wits end on what to do. I've tried assigning the innerHTML value "NA", just plain text, and it has the same effect.Without being too confusing, I have a table of data inside a <div> where the user can navigate up/down by pressing the <enter> key, pg up/pg dn and arrow up/arrow down. When they move from record to record, I'm highlighting the new row and "de-highlighting" the old row. The row has many fields but only one fill in field which is where the user enters the quantity of the item to be ordered. This is on a local network using the Firefox browser.
Without the above line, all is well. When I use the above line, it messes up the highlighting of the row but also makes the fill-in field "appear" disabled. What I mean by that is when you type a number, you don't see the value change (even though the field has focus and the value is selected) but once you leave that line, the value you typed then appears in the fill in. Normally the value will change as you type a new value.
I'm running a PHP script to check whether the user is logged in or not. If the user is not logged in they are redirected to the login.php page.What I would like to do is redirect them to the PHP page but also grab the URL they were previously on and assign it to a hidden field in the login.php so that I can redirect them back to the page they were on while keeping the URL bar clean.Problem, I know that PHP cannot recognize a hash [URL] so I would need to grab the url through javascript instead of PHP.
View 3 Replies View RelatedI am currently putting together a trivia game and I have stored several items in an array for example the questions, and the answers, points value... etc.
but my dilemma is I have to assign an "id" to the elements in the the array so i can use the function getElementById() to call the information. I do not have a clue how to do this.
*** also the second issue is my array is showing an error as UNDEFINED BUT i have declared it in "var triviaArray"
this is my array:
var triviaArray = new Array [
triviaArray["What's the capitol of Canada?","TORONTO","VANCOUVER","OTTAWA","QUEBEC",10,"choice3"],

IE has no problem with this, but Firefox throws an exception - "Illegal operation on WrappedNative prototype object". Is it within its rights to do so?
