I am having difficulty with the isNaN built-in function. Here is the code that I have written, with the event handler onchange, the function does not return the desired response.
CODE:
Here is an example of the event handler code...one of three calls to this specific function...
<input type="text" name="zip_billing" size="5" maxlength="5" onchange=" return checkNumber(this.value);" />
I am trying to get a response from a webservice, but it seems it cannot be parsed properly (this is the XML error; XML Parsing Error: no element found Location: moz-nullprincipal:{11c9829b-3cae-4d8d-bdfe-265c905cb82e} Line Number 1, Column 1:)
$.get(linkWS, {}, function(li_data, li_status, li_Request){
callback(li_data, li_status, li_Request);
}, "xml" );
In the Firebug response field I don't see any data at all.
Can assign a new function to a built-in object in Firefox:
But IE and Opera don't have a MouseEvent or HTMLElement that can be set up in the same way. Can you do this in IE or Opera, or just Firefox, and maybe Webkit?
<html>
<head>
<script type="text/javascript">
function convertHaH()
{
var mylist=Number(document.getElementById("percent"))
document.getElementById("remainder").value=100-mylist.value;
}
</script>
</head>
<body>
<form>
First percentage:
<input type="text" id="percent" onchange="convertHaH()">
<p>Remaining percent: <input type="text" id="remainder" size="20"></p>
</form>
</body>
This code works great, it will populate the second box. But I would like it to check if what was entered is a number if it isn't then an alert box shows stating they need to enter a number between 1 - 100, else it populates the second box.
I am actually learning Javascript atm as part of a course I am studying. I am wanting to do some validation for a form I have created. It doesn't validate for non-numeric characters like I want to do and it does not display the end result either.
[Code]...
I'm performing some validation functions on a form I've created.For the phone number, I have 3 text boxes lined up next to one another. The first is for the country code, the second is for area code and the third is for the remainder of the phone number.I have used the following in order to detect whether the input value isNaN.
Code:
input = document.getElementById("phone1");
if (isNaN(input.value)) {
errorText += "[code]...
As I have three text boxes for the phone number, can I group them within this one statement? So, ...getElementById("phone1, phone2, phone3"); ?If not, what would you recommend?
I have developed script library for dispalying calendar for my web
pages.
To display calendar, i am using div tag and with in div tag, i am
defining the dates.
This div tag is wrapped by IFrame control, in order to make the div tag
overlap over 'select' controls.
These controls (both Div and IFrame) are dynamically generated and i am
setting the width of div tag based on my text box associated with the
calendar.
IFrame width is determined by Div tag's offsetWidth.
This calculation works properly in IE 6.0, but when it comes to Firefox
1.5.0, the offsetWidth has been calculated wrongly and my calendar
shrinks abnormally.
So I have a form with three drop down boxes. When I select a value in the first drop down box, the options for the second dropdown box are retrieved from a PHP script via AJAX. Likewise, when I select a value in the second dropdown box, the options for the third are also retrieved via AJAX. This is done with an onchange handler. You can see how this works at the following: [URL] That works perfectly. I run into problems later however when I try to change the value in one of the dropdown boxes with Javascript.
See, I have a text field that a user can enter a string into (this feature is not in the sandbox at that URL yet), and that string will then be used to populate the dropdown boxes. For example, if the user enters "subject-genus-dog", then "subject" should become selected in the first dropdown box, "genus" should be selected in the second dropdown box, and "dog" should be selected in the third. The problem is, the onchange handler doesn't seem to trigger when the value of the first dropdown box is changed to "subject", and thus the second dropdown box does not get populated with options via AJAX, and so "genus" cannot be selected because the only option in the second dropdown box is the default "select a value in the first box".
Why doesn't the onchange handler trigger when a dropdown box is changed with the following code? [code=text]document.getElementById(destination).value = reloadValuesSubArr[1];[/code] Is this a bug in Javascript? Or am I doing it wrong? Keep in mind that the value of the first dropbox changes without issue, but the onchange handler does not trigger.
When I click on a link I have this event:
$.ajax({type: "POST",
url: "/req.php",
asynchronous: false,
dataType: "xml",
[Code]......
The php file check the "op" and call a function that return true (if the query is ok) or false (if the query is not ok). What I have to do to test this value? I mean....jQuery make the sync call, call the php script that run a INSERT query. I need to test in jquery if this QUERY was correctcly lanced. I try with the code above but I can understand that the success parameter is only for the good call of the php script, not for the response.
I have an ajax post which returns a large html response. It is getting truncated at 98784 characters everytime. Is there a limit to a response size or a way around this?

Here is my ajax call:
I would like to be able to take some action (implemented in a
function) when a property is assigned a new value (much a page is re-
rendered when, for example, a style is changed). So if I do ...

I want myObject.myFunction to be called. Is this possible at all?

How can I scoll the content of an Ifram to a desire Position?

I'm still a beginner to javaScript, but I'm trying to write a script for a simple image change using next and previous buttons. The following script works, except that the images do not rotate in the desired order. The script works as long as you don't switch from next to previous, which is when the wrong images are shown.
<html>
<head>
<title>Button Click 12</title>
<style type="text/css">
button {
font-family:georgia;
font-style:italic;
font-size:12px;
font-weight:bold;
cursorointer;
border:1px solid red;
background-color:aqua;
display:inline-block;
padding:2px 20px;
margin:0 5px;
} .....
The goal is to change the source on the fly (as with a firefox extension webdev or another or even Greasemonkey) to add a link. Until then, easy does it work well. This link launches an application ajax jquery like:
$.get(...) or even $.ajax(...)
If I'm on [URL], added my link, I click and it works, I see the ajax request and pass my "alert ()" gives me the return of application. Great! But if I'm on a site other than mine (the url of the ajax request is [URL] while I'm at [URL] for example), the return of the ajax request is empty.
I have Javascript code that looks like this:
var data1;
$.post('save_search.php', formData, function(data) {
data1 = data;
});
jsonData = eval('(' + data1 + ')');
if (jsonData.return_status.search("successful") > -1)
$('#msg_div').html("<font color=red>Search was saved</font>");
else
$('#msg_div').html("<font color=red>Search was not saved. Try saving again.</font>");
"data1" comes up as undefined in the statement
jsonData = eval('(' + data1 + ')');
Even though "data" is a perfectly correct JSON string *inside* the callback function! I can put the eval statement inside the callback function and it will form a good JSON object, like this:
jsonData = eval('(' + data + ')');
I'm simply trying to get my Ajax response data to the outside of my callback function so I can use it in other Javascript code. I've never seen an ordinary function behave this way.
I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE).
The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden.
However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case.
Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed?
i've got a function which makes a call to the database( via jquery $.post) to check if a username already exists. All the data I get back is fine and both the conditional statment works as intentded. I just can't get the function to return a value to the other function that calls it. Could this be something to do with the scope.
Code:
function checkIfUsername(o)
{
$.post(""+CI_ROOT+"index.php/admin/check_if_username",{
username: username.val()
}, function(data){
if(data.bool == true){

I am using jquery.ajax() to make a POST call to web server which returns HTTP 201 response for successful creation of object at server. Since 201 is a success I expect the success function specified with jquery.ajax to execute but instead it executes the error function specified with jquery.ajax. Here is how I am using jquery.ajax call.

Afternoon all, Have a pretty simple function, that requests a number to be entered.
I want to return that number, but i seem to be typing something wrong in the return value.
function newFunction(a, b)
{
var newArray = new Array(a);
for (var i = 0; i < 5; i = i + 1)

I am populating a field on my page using a php include. I am asking javascript to update another element with that field's value. The value written to the select input box is Ƈ:Any Provider'. The process works fine in Firefox. In IE6 it does not write. the value nor does it throw an error. What am I doing wrong?
input form:
[PHP]<form method="post" action="" name="inputForm">
<label for="provider">Name of Provider</label><select class="input" name="provider" size="1" style="width: 20em"><?php nameprov();?></select>
<input type="button" name="button" value="Upload" onclick="postthis()">
<div id="status"></div>
</form>
The script in the head element:
function postthis(){
var provider = document.inputForm['provider'].value;
var report = document.getElementById("status");
var message="The Value of Provider Block is: " + provider;
report.innerHTML = message;
}
In firefox, "The Value of Provider Block is: 1:Any Provider" is written in the report element. In IE6, "The Value of Provider Block is : " is written in the report element.
I know the answer must be yes, but I am really having a hard time figuring this out. I have a simple script below, that calculates age (I know I need to do some more work). I want to redisplay the value returned from the function. It works OK, because the result displays correctly in the alert. Code:

I have a multiple choice quiz that works fairly well. However, instead of it presenting "End of Quiz" message when last question is completed I need it to take the user back to the beginning (question 1) but with no indication to the user that this has been done.
