Null Variable - Error: "cobj1 Is Null"

Feb 26, 2009

I put a long script but the problem is small.

var book1 = bobj1.value;
var chapter1 = cobj1.value;
var verse1 = vobj1.value;
var book2 = bobj2.value;
var chapter2 = cobj2.value;
var verse2 = vobj2.value;
[Code].....

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]

Form Validation Check For NULL?

Jan 8, 2010

I am putting some validation on some forms at work. The users have asked to put something in place to make sure that if you enter something in on field that you must enter something in the corresponding field.

Example : Lets say there is a Company field and a Position field. Well they would like that if you enter a Company you should enter a Position and the other way where if you enter a Position you just enter a Company.

Ok so thats easy enough I did something like the following.

if((form.Company1.value=="") && !(form.Position1.value=="")){
alert("Enter a Company into the Company field for row 1 or enter N/A");
form.Company1.focus();
return false;
}

Well now they want a message box to give the user the option it ignore that they have a blank field, and more or less want a �hey just to let you know, you didn�t put anything here

JQuery :: Check Length Is Null Or Not An Object?

Sep 26, 2009

The function below results in this error and I'm not sure how to correct it? The initial value of the field is 0.00, but it doesn't look like it's relevant... That is, even when the value isn't 0, it still results in this error.

if($("input[name='b2h']")) {
$("input[name='b1']").bind("keyup", b2);
b2();

JQuery :: PHP Variable Is Null?

Sep 15, 2011

I'm currently trying to use jQuery to update a database without refreshing the page. I have 3 pages, the visible PHP page (test.php), javascript.js (jQuery file), and file1.php (page to run queries and update database) test.php is just a file that uses classes to make each link unique. when the image with the class is clicked, it runs javascript.js. ( i know there's a reference to file2.php and i won't be using that until i get this working.. )

Onclick Accordion Works In IE7 But Not IE8 (variable Is Null Or Not An Object)

Apr 28, 2010

Hey all, I'm using a fairly simple accordion script. When I went to take a gander at the page in IE I found that the onclick function of the script doesn't respond. It works in FF, Safari, Chrome and Compatibility Mode in IE 8

the error message IE gives me is

Message: 'h' is null or not an object
Line: 13
Char: 77
Code: 0
URI: http://proposalfor.us/js/script.js

The problem line (as far as I can tell) is:

this.a[s]={}; this.a[s].h=h=T$$(e,v)[0]; this.a[s].c=c=T$$('div',v)[0]; h.onclick=new Function(this.n+'.pr(0,'+s+')');

Check If Variable Is Set

Jul 4, 2003

is there a JavaScript equivalent to the PHP isset() function? Basically, I just need to see if an array has already been created. If not, I'll create it. If so, I'll add to it. I tried something like...

if (!myArray) {
var myArray = new Array();
myArray[0] = someString;
n = 1;
} else {
myArray[n] = someString;
n++;
}
...but just got an error message that myArray was undefined. What's the "right" way to do this?

Check For The Existence Of A Variable With A Calculated Name?

Jan 29, 2009

I'm processing a form with numbered fields, but I don't know how many fields there are. Might be 1, might be 20. So I'm iterating through 1-20 and trying the following test:

for(i=1; i<=20; i++) {
if(typeof(eval('document.edit_orderitem_form.field_'+i+'.value')) != 'undefined') {
[doing stuff with the form field here]
}
}

The script quits on that line with "Undefined value" showing up in Safari's error console. I just can't figure out how to eval() the name of a field when it may or may not exist.

Ajax :: Redirect / Refresh And Variable Set / Check

Sep 5, 2010

This is my first adventure into PHP/Ajax/MySql/Javascript and is pretty much my first web project. I've been trying to tackle this problem for a little over a week now. My main objective is that I want to display php content pages inside a div on the index page without refreshing the page (iframe style). I don't want to stop search engines indexing the individual pages so I need a mechanism to redirect to the index page so that the page is displayed properly. I'm not bothered if it takes them to the exact page and I'm redirecting them to the section of the site where they the page is kept.

I also want a mechanism to redirect if a second search engine link is clicked that belongs to the individual page (ie image links that belong to the same page). This is only a problem because the php session has already been opened and a php variable has been set by the first redirect. All the redirections are taken care of by PHP and I got the redirection of multiple instances working ok by setting and unsetting session variables. This PHP code is included on every content page.

But, when I added links to the index page and try to navigate between pages, it all goes pear-shaped.When the links are clicked it calls up the Javascript code, inside which a PHP variable is set (I dunno if this is the "done" thing, but I came across the solution somewhere on the Interweb). This is the first thing checked when the content pages are called up. If the variable isn't set, then it runs through the redirect options.

The problem is that after clicking the link when the page displays it always refreshes the index page which I don't want it to do and which is why I'm thinking it's the setting of the PHP variable inside the Javascript that's going wrong. (Also why this question ended up in this section). Is there any way of getting this going without passing the variable into the url (not that I'm against this option)? Index page code, PHP Code (before HTML)...

Code:
<?php
if(!isset($_SESSION))
{
session_start();
}
// set the session var to the index page url which I think remains until browser close
$_SESSION['pagecheck'] = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
// set the section var if it hasn't already been set by one of the content pages
if(isset($_SESSION['sectNum'])!= "undefined")
{
$_SESSION['sectNum'] = "0";
}
function getSection() .....

Additionally, are there any potential security threats that should be tackled (bearing in mind that I don't want to use cookies, I'm not against this either but decided if they are switched of it may become an issue, and I'm not going to be handling any sensitive information). I really don't want to use Iframes due to any javascript switching off related problems (yes there is a javascript testing function included in my full code!).

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

JQuery :: Uncheck And Check (re-check) A Radio Input On Page Load?

Oct 4, 2011

Here is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?

Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.
