Nov 9, 2011
Does not work:
<BODY onload="s.innerHTML=('im1='+im1.offsetLeft+','+im1.offsetTop+';im2='+im2.offsetLeft+','+im2.offsetTo p)">
<form style="position:absolute;top:40;left:40;">

I built a form that utilizes arrays for storing data, prototype objects stored in arrays, and DOM using getElementByID and getElementByName. Now, in XP SP2 with the security center turned on, I get alerted by IE6/7 that there is an ActiveX script on the page and it asks to be allowed.
I don't want users IE to see this ActiveX warning. First, the users going to be using this form are not exactly tech savvy enough to know to allow it. Second, I had no idea JavaScript was related to ActiveX--which begs the question, what sort of things cause JavaScript to be flagged as ActiveX?

How would you go about writing a script to switch the style sheet if low bandwidth is detected? Is this even possible?

I'm loading content using an XMLHttpRequest and sending it to a Code:div on the fly in Greasemonkey. However, when I try to traverse through this newly loaded content and retrieve the innerHTML, jquery returns a null.
My code is as such
Code:
var xhReq = new XMLHttpRequest();
xhReq.open("GET", linksRaw, false);
xhReq.send(null);

I'm just starting to learn languages like jQuery, PHP and AJAX. I will post exactly what a potential client asked me. I'm not willing to say no, because everything else he asked I can do myself, but if it's far beyond my capabilities, I may have to just hire someone to code this part.
Quote: For our home page main menu bar, we would like to have a script (that we design) that if it recognizes a cookie, it shows a slightly different menu bar than if it doesn't see our cookie. For instance, if a user is "remembered" we want the menu to have a support button visible, if the user isn't remembered by our script, its button would then be "Free Trial" I understand exactly what he wants, just not sure how best to go about it. I believe I've seen this before, and I thought maybe AJAX was the best way to do it, but please, correct me if there is a much easier way.
I figure it's a matter of just showing and hiding an object in a kind of IF / ELSE situation.

I need to get JavaScript to change the font size used for a website if Opera is detected. I have been trying this but it hasn't worked:
function changeFooter(){
if (navigator.userAgent.indexOf("Opera") >= 0) { // if I alert this line the output is 0
document.getElementById("footer").style.fontSize = '0.5em';
};
[Code].....
I was hoping that I could benefit from your collective wisdom as I am not sure where I am going wrong with this and several hours spent searching the web for answers have been fruitless so far...
My knowledge of JavaScript is not very extensive, I haven't studied it in great depth so perhaps I am making some very silly mistakes here.
My pseudo code for this exercise is something like this:
detect browser
if browser = Opera {
change font-size for body to 90%
}

IE has a real problem working with my site at the moment and I want to force people to only NON Microsoft browsers for the moment until I get around to fixing the issue (I am only in beta, so its not a major issue)I have seen guides on how to do the detection, and im sure this is a real simple question, but how do i get it to stop loading the page (i.e just provide a blank white page) straight after the popup warning message? this is what i have
Code:
<SCRIPT language="JavaScript">

I added a test script to detect the change of a html select object and it is not firing.
The select is within a table row. The table id is: flogtable and the select is in the first row.
The test function I added is:
$('.symselect').change(function() {
alert('Handler for .change() called.');
});

I was reading various articles on browser detection with javascript and I know it can be unreliable and unprofessional at times, but I was just playing it to see if I could get something working. What I wanted to do was attach a stylesheet if the browser in safari.
With what I remember from the articles I read, isn't there a function that is navigator.appName(); ? I have written it in sorta of pseudo-code below:
Essentially,
if(browserName=="safari"){
<link type="text/stylesheet" href="safariStyling.css"/>
}else{
<link type="text/stylesheet" href="defaultStyling.css"/>
}
I know that there is a .html() jQuery function where I can write html in the head of the document like so, head.html (HTML GOES HERE); but I have heard and form experience that mixing javascript and jQuery function can be dangerous. I would detect if the browser is safari and then link a stylesheet if true?

So my task was to build basically photo-based department org-charts for a SharePoint 2007 environment. Not sure why I was asked to do this as the last time I web designed was when Netscape 4.0 and IE4 were still duking it out, but whatever.I inserted my images (125x125) into tables and everything looks great. on my screen.Boss's screen, a slightly smaller monitor with a lower resolution, not so much.I'd like to be able to dynamically resize the image display sizes based on detected screen resolutions, or failing that, have at least 2 image libraries using 75x75 and 125x125 and then load one image size or the other based again on detected screen resolutions.

I have a form built and on the onclick event I validate all of the
fields and then if the form is ok, on the submit event I run a
javascript function to set a cookie and download a file from the
current window.
I have a cgi script provided by my web host to send the contents of the
form through email but they only show me how to use the cgi script to
send email through the submit event of the form.
ie. <form name="downloadform" method="post"
action="/cgi-bin/cgiemail/mailtemp.txt" onSubmit="return
Validate(this)">
Can I utilize the cgi script/link from my javascript function and still
send the contents of the form through the cgi email??

I've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: [URL] And here is the code in question:
[Code]...
I have two questions...
Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this?
Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document?

How does one cause a form element to appear ONLY if a certain form selection is made before it?
That is for example say there is a form element of type Radio called "format" so only if they select format value = normal then the form input fields called URL and Name are to appear as the next choices otherwise form input field Group and checklist Places are to appear as the next choices.

I am having a problem with the submit() method that is driving me nuts. I'm using document.form.submit() with large text fields (approx. 2000 characters) and am getting a "Invalid Syntax" error. If I do the same thing with a text field of under 1500 characters, it works fine.
Is there some size limit here that I don't know about?

I've have a function to take the value entered in a form text box, add 50 to it and put the result in another text box.
When I enter 650.5 I get 700.5 exactly how I'd expect. But when I enter -650.5 instead of getting -600.5 I get -650.050 as though it is failing to parse the float due to it being negative. My understanding of parseFloat was that it recognises negative numbers. Is there a nice simple way to get this to work?

I would like to have a main form (written in PHP) that has a "lookup" button next to a text field. When the user clicks "lookup", it should open a new window that lets them search (child.page1). When they enter a name or DOB into the search form, it submits the form through PHP (via POST), to a results page (child.page2). This displays all persons in the database which have a name or DOB == to the search term(s), with a checkbox next to each match. They click the checkbox (or alternenatively, a link), and return the checkbox value to the main window.
I have everything working right now, except that (child.page2) doesn't recognize the main window. If the data is entered on (child.page1), it works fine. I'm not very familiar with javascript.. is this even possible? I've considered using frames, to keep the parent-child relationship evident to the computer, but figured I'd check to see if there's an easier way.

I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.

Here is the issue I am having: In my project, I have a index.php page with a sidebar menu and a div id called œcontent.The user can select different menu items and perform searches from the database and make updates to their account. Im using ajax to load all of the menu items and all of the forms into the div id "content" on the index page. The Forms all load into the target div as they are suppose to with ajax.
However, on the mysettings page I have two forms and two different buttons, one called save and the other called update. When a user wants to edit their account information and makes changes to their account they clicks on either button and the form processes the information and updates or inserts data into the database correctly but the problem is that after that the form or page does not display the form back in the div id "content" like how it was loaded originally in the index.php page. The problem is that it reloads or refreshes the form page without the index.php page being involved. That is does not get reloaded or updated inside the index.php page content div again.
What I would like do is have all of my forms process whatever is submitted on the page and display the results back inside the same content div on the index.php page again. I know I am missing something because all of my forms are doing the same thing. I am hoping someone can help me out. I would be very grateful for example code that I can learn from since I am still relatively new to web development. I am posting some sample code below.

And now the code i use to action it:

From what i can see the fields match, it all links up correctly but still it will allow blank forms to be sent.

I've put together what I think is an illustration of my problem at [URL] Quite simply, I need to be able to access the elements of the form without referring to them by ID as the whole form is intended to be cloned. I intended to do this using parentNode and childNodes[] together with the 'this' keyword. My understanding of 'this' in this context is that it should refer to the HTML element calling the function, i.e. one of the radio button inputs. However this gives the error "Error: this.parentNode is undefined"

I have a simple three-field form in a UI Dialog that, prior to POSTing, I need to validate using the jQuery Validation plugin.Currently, if the user clicks the form's Submit button (the form's action for the PHP form handling is the page with the link that opens the Dialog in the first place) with a field not properly filled out, the Dialog just closes.Clicking again on the link that opens the Dialog form will show the form with the error message(s) that the Validator generated on the previous click of the submit button.How can I keep the Dialog open and prevent a POST until the form validates?

We're using Malsup's form plugin v2.82 and jQuery core 1.6.2. We're having issues in IE7 where, on a form with file upload, form fields are being dropped before the form is submitted to the server.We tracked it down to the `fileUpload` function, specifically line 196 where each field in the form data has `.attr('disabled',false)` run against it. If we change this to`.prop('disabled',false)` it all works fine.I don't see a clearly marked place to submit bug reports for the form plugin, and wanted to verify that others see this as well,

I'm having troubles with an existing J2EE application (which uses Dojo) and in which I'm gradually introducing jQuery. The specific issue is with the malsup Form plugin and the JSON returned from a form submission: the error callback is always called, regardless of what happens on the server side, and the error is always "parsererror". I'm using jQuery 1.4.2 and the 2.45 version of the malsup Form plugin.
For example, given the following code:
$(document).ready(function() {
var options = {
dataType: 'json',[code]....
the server receives the submission and handles it without errors, then in the browser I always get the same alert from the processAddressEditSubmitError() function, with an "Invalid JSON" message:
pStatus=parsererror
pErrorText=Invalid JSON: {"nickname":"trytrez","success":"success"}
However, the JSON looks OK for me (and http:[url]...agrees that it is valid).

I'm having trouble changing the font color of my labels ONLY when I stop the form from submitting due to blank fields. I'm not sure whether if just changing my CSS will achieve what I want, or am I going to have to add somethig to my if else statement, or both? I would think I would need to change CSS to :
label.onfocus {
color:red;
}
but a little confused on what else.
