Simple XmlHttpObject - Alert Returns A Value Of Null

Feb 10, 2010

When using the code below the alert returns a value of null. In the past this has never happened, it has always returned the xml file I'm requesting. I have noticed a strange difference between browsers. This script is used to fill a form automatically. In its current state it works perfectly in opera, but does not work in firefox or IE (used to work in all the browsers). I'm by no means a javascript expert, am I missing something here?

Textarea Populated But Post Returns Null

Jun 18, 2011

I have a form in which I preset some text inside a readonly, disabled textarea using javascript ('data' being the text):
document.getElementById("link_of_current_view2").value = data;

However, once I call my .php script to process the form, the element is null. How do I get it to pass along that data, which is in the textbox when the user views the form?
<div id="sendlink" class="contact_form" style="z-index:10;">
<a class="close" onclick="document.sendlink_form.reset();return false">CLOSE</a>
<form id='sendlink_form' name='sendlink_form' method="post" action="sendlink.php" >
<label for="link_of_current_view2">Link: </label>
<textarea id="link_of_current_view2" name="_of_current_view2" class="link_of_current_view" rows="2" disabled="disabled" wrap="soft" size="58" value="" readonly="readonly" value=/>

Regular Expression Match Always Returns Null

Feb 12, 2010

I found this regular expression on the internet and it works fine when I test it in various validators on the web.

Code:

^(((0?[1-9]|1[012])/(0?[1-9]|1d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]d)d{2}|0?2/29/((19|[2-9]d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$

It's purpose is to check for valid date and allows formats mm/dd/yyyy, m/dd/yyyy, mm/d/yyyy or m/d/yyyy.

When I try it with the code below it always returns null.

Code:

function isValidDate(/* String */ p1_date) {
var x = "^(((0?[1-9]|1[012])/(0?[1-9]|1d|2[0-8])|(0?[13456789]|1[012])/(29|30)|(0?[13578]|1[02])/31)/(19|[2-9]d)d{2}|0?2/29/((19|[2-9]d)(0[48]|[2468][048]|[13579][26])|(([2468][048]|[3579][26])00)))$";

Double Ajax Calls, Using $F The Second Time Returns Null

Feb 11, 2006

I'm using the $F of the prototype library to send data through the Ajax
Request. I'm having problems using the $F to reference fields sent
back through an original Request. My first request sends a form back
to the user in the type such as <input text name=foo> and at the bottom
of the returned form I have a second ajax call to send the fresh data
to the another script. The problem is that the new data in the form
cannot be referenced from $F. My question is how can I pass the new
data in the javascript to another Ajax call either by $F or by other
means?

ActiveXObject("Microsoft.XMLHTTP") Returns Null?

May 1, 2007

Just trying to create a basic xmlhttpobject.
However, the following always returns null

xmlhttpobj = New ActiveXObject("Microsoft.XMLHTTP")

(it is Microsoft. and not Msxml2. I've already narrowed that part
down; just trying to create the object now)

If I check for the value of xmlhttpobj, it is always null or
undefined.

IE settings aren't blocking any ActiveX

Creating New Line Characters When Using NodeValue?

Jan 1, 2009

I was wondering if it is possible to create a new line character when modifying a nodeValue with Javascript.

I'm not too familiar with the DOM model so it may not even be possible.

I have <p id="something">text</p>

and when someone clicks a button, 'text' gets updated. I believe I used

Code JavaScript: document.getElementById("something").childNodes[0].nodeValue = "new value";

or something similar to update the text for a p tag).

However, if "new value" is "new value" or "<br />new value", it either appears on the same line and doesn't do anything different (including ), or it actually changes the text to read exactly "<br />new value" (using <br />).

So, is it possible to move part of the text to the next line, or will the DOM model not allow me to do so this way?

JQuery :: Getting Complete Xml Text From A Node - XML NodeValue

<object>
<header />

<value1>1</value1>

However, this currently returns 'undefined'. Is there any easy way to do this, or do I need to actually parse the XML below thing1 and manually write my own XML sub-tree?

NodeValue - Text Appearing Above Rather Than Inside Node

Oct 9, 2005

After much work, I've come up with some Javascript/DOM that almost works :)

function setblocktitle(id, text)
{
document.getElementById(id).firstChild.nodeValue = text;
}

With my HTML being:
<div id="hits" class="modules">
<h2>Hits</h2>
<div class="blah">
...

The problem is, when calling setblocktitle with setblocktitle("hits", "Totals"); I end up with the attached image rather than "Hits" being replaced by "Totals".

XmlDom - Compare A String To A .nodeValue It Always Fails, Even If They Are Same?

Apr 13, 2011

I'm still pretty new to javascript and dom, but have been coding with other languages for a while.When I try to compare a string to a .nodeValue it always fails, even if they are same. From what I've read typecasting is automatic in javascript or is this incorrect? For instance

var myGreet = "Hello";
var myFrag = myXML.lastChild.firstChild.firstChild.childNodes[0].nodeValue; returns Hello
if(myGreet == myFrag){ always returns false
alert(myFrag);
}

Null Is Null Or Not An Object Swfobject

Jul 30, 2011

I did find the javascript twice in my code, once in the header and once here, so i removed it from the header. I also changed to src to the full url. But i am still getting this and i dont know why. the file is located in the root directory. found a solution. basically Internet Explorer is crappy and doesnt like the setAttribute property so had to change the onchange handler by directly changing the attrbute for the object like so.object.onchange = function() {}i have no idea what they means, does that mean i need to change swfobject.js or does that mean i have to change my xml request. and if it is the swfobject i have no clue what they mean or what lines

Null Variable - Error: "cobj1 Is Null"

Feb 26, 2009

I put a long script but the problem is small.

var book1 = bobj1.value;

var verse1 = vobj1.value;
var book2 = bobj2.value;
var chapter2 = cobj2.value;
var verse2 = vobj2.value;

I don't know if this is written properly: if(bcv[a]!= ""){ The reason this is happening is because the error shows: Error: cobj1 is null Source File: [URL]
