View 8 Replies View RelatedI 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
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();

I'm doing some simple tests and I can't get this to work on a wordpress site. Basically I'm trying to fadeOut a div with id of "box" when a link is clicked. I mentioned Wordpress because the head code is loaded dynamically into the page template, as well as the body content. I wasn't sure I this made a difference in diagnosing the problem. When I load the page, Firebug keeps giving an error...
$('a') is null
Here is my stripped html code...
<head>
<script src="[URL]"
type="text/javascript"></script>
<style type="text/css">
#box {background-color: red; width: 300px; height: 300px;}
</style>
<script type="text/javascript">
$(function() {
$('a').click(function() {
$('#box').fadeOut();
});
});
</script>
</head>
<body>
<div id="box">
</div>
<a href="#">Fade Out</a>
</body>
document.exeCommand ('Copy',false,null); is not working in mozilla

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.....

var xmlHttp = createXmlHttpRequestObject();
// holds the remote server address[code].....
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
View 2 Replies View RelatedI've been trying for hours and I can't figure out why IE6 is throwing an derror on the following line of code.
Code:
var parts = rgbString.match(/^rgb((d+),s*(d+),s*(d+))$/); This is the function:
Code:
function rgbToHex(rgbString)

And this is the error:'null' is null or not an object
I have a webpage with a single form. Under that form I have two separate lists of checkboxes. One set is called eventList the other is assigneeList.I have added two other checkboxes, one is as follows,
Code:
<input name="checkAllEvents" type="checkbox" id="checkAllEvents" onclick="checkAll(this.id, 'eventList')" />
The other is,
Code:
input name="checkAllDelegates" type="checkbox" id="checkAllDelegates" onclick="checkAll(this.id, 'assigneeList')" />
What I want to do is, check all the assigneeList boxes with the same value as the checkAllDelegates checkbox. And the same go the other set respectively.Through rummaging around I came up with the following,
Code:
<script type="text/javascript">
$(function checkAll(id, name) {
$("INPUT[@name=" + name + "][type='checkbox']").attr('checked', $('#' + id).is(':checked'));
});
</script>
However nothing seems to happen when I check the boxes, what am I doing wrong?
I'm trying to check the client's window height and then apply some proper css in some div classes. The code I use does not work in IE6 and IE7.
<body onload="document.write(document.documentElement.clientHeight);">
I resize the window, I refresh the page and the height that the code returns, remains the same. I searched about it in google and it seems that the document.documentElement.clientHeight is compatible with IE, so I don't understand why is this happening
The code works but i need to have he input on the top of the form and it's cal it right.when i move it down it works.
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

I'm try to get the values to add correctly and just not sure what i'm doing. (novice).
i have 3+ sets of 9 with a answer box. just wanted to get the values to add. code...
I'm having trouble making this work. I have this script inside a .js file. I haven't specified a height in the .css file for #cellsouter, so the script can take care of it. I've tried adding curly brackets and semicolons but it's not playing ball
Code:
if (screen.height<=960)
document.getElementById("cellsouter").style.height="55%"
[code].....
here is my html (very short and simple)

I am trying to hide it after 1000 milliseconds delay
$("#selectall").delay(1000).css("visibility","hidden"); works finebut it sucks when I have multiple checkboxes
so$("input").each(function () { $(this).delay(1000).css("visibility","hidden"); });
the above doesnt work. It just hides it without a delay.
Tired to see what's wrong here!

I'm trying to create a demo to display a new way of showing our data.I thought I remembered this being pretty simple but I'm hitting a snag. The table, the mouse over, and the check row by clicking on the row all work separately but when the check row by clicking function is on, seen in the first row, the checkbox stops working.

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]
I have this code in a function.

Alert 1 is to check if the program enters the function. And it does in all browsers. But when it comes to alert 2, Firefox does not execute the alert. So I assume there is something wrong with firefox executing the onreadystatechange. By the way this is the code for initAjaxObject()

I keep getting an error stating "getElementById("ballElement") is null, but I have a div with that exact id. I have looked at the JS script before that line, but found no errors there either. Please take a minute to see if you find something.
