check emailAddress

emailAddress null pointer ?
property .value exists ?
range of value of .value ?

HTML

funktion document.getElementById() uses param during parsing of document

so '<%=hfEmail.ClientID%>' must be a real ID or filled BEFORE parsing javascript.

put javascript at end of body, no in head (head is parsed at first before body).

<script type="text/javascript">

.... what you want

try it in jquery ready function.
$(document).ready(function()
{
var hiddenVal=$("#YourId").val();
});
if you use master page in aspx, then you can find the element by name also.
$("input[name='elementName']")

How would you define the optimal weight in the first place? You would need a list that contains all the other parameters that woould lead you to the correct value.

Tainted Canvas

Hello,

I've being trying to get some animations done in a canvas which are quite similar to Create an HTML5 (and JavaScript) Maze Game with a timer[^]. Unfortunately I've got the same erro that happens on the project's article. Unless you use Firefox you'll get:

Unable to get image data from canvas because the canvas has been tainted by cross-origin data. 
Uncaught SecurityError: An attempt was made to break through the security policy of the user agent.

From my research, you can add to google chrome shortcut the extension --disable-web-security or host the files in a localhost server.

Both ways can make it work, but I would like to know if there is a way for cross-origin not to taint the canvas? Something like a property from the canvas that I could disable/enable or some other coding related solution..

There are no secrets to success. It is the result of preparation, hard work, and learning from failure. Colin Powell

I sure hope not - if there was, what's to stop malicious code from loading images from your local file-system?

Just use a localhost server. You can write one in c++ that compiles to a 25kb executable. Of course, you could download Apache or a different one of your choosing.

Is there any way to avoid activex in javascript ?

30-Oct-13 0:27

In need of desperate guidance

1. Is there any way to avoid activex in javascript for reading
Documents and constructing xmls?

2. Actual there is an problem with the client, he doesnt like the IE security settings like "Access data source across domains" under Miscellaneous and "Run ActiveX controls and plug-ins".

And It should support IE 7,8 and above.If possible that should work in cross browser also.

Currently in Javascript, we are using the below codes:

var xmlDoc = new ActiveXObject("MSXML2.DOMDocument"); -->for xml construction.

var stm = new ActiveXObject("ADODB.Stream"); --> for reading the doc and docx file from client temporary path.

What is needed:

1. We need to find an alternate in order to avoid using the ActiveXobject.

OR

2. We need to automate the Internet Security Settings in client machine.

Could some one help me in this please?

Thanks

If above ie. 6 you should be able to parse XML documents directly from Javascript - see here for example[^]

Accessing a file from the local machine, though, is more of a problem unless the user selects the file. Could you supply the file vie a web service, for example?

retaining jquery datepicker data between views in ASP:MultiView

Brad7323-Oct-13 6:54

Brad73

23-Oct-13 6:54

Let me preface this question with the fact that I am fairly inexperienced with jquery. Now to the issue, I have 3 date pickers that are placed upon two different views in an ASP:MultiView. They are working perfectly, no issues at all.

I need to retain the values entered in two of the inputs which I can do to one or the other but not both for some reason. each of these reside on a different view so I am not sure if that is the issue or not. In the code below, the data will be retained for the first if statement only. If I switch the if statements then the opposite input will retain its value but never both items. What am I doing wrong? Each if statement pertains to a different control so it is not supposed to be an if else type of scenario. It is like only one if statement is allowed to fire and I have been staring at this for a while with no idea what is happening so any help would be great.

JavaScript

<script type="text/javascript" >

       $(function () {
           $("#txtDoB").datepicker({ changeMonth: true, changeYear: true, yearRange: '-125:+0' });
           $("#txtSpouseDoH").datepicker({ changeMonth: true, changeYear: true, yearRange: '-75:+0', altField: '[id$=hfSpDoH]' });
           $("#txtHiredate").datepicker({ changeMonth: true, changeYear: true, yearRange: '-75:+0', altField: '[id$=hfHireDate]' });

           if ($("[id$=hfHireDate]").attr("Value").length > 0) {
               $("[id$=txtHiredate]").datepicker("setDate", new Date($("[id$=hfHireDate]").attr("Value")));

I am missing something with these frameworks. They seem pretty cool for some things, but how do you secure the REST service?

With these frameworks you have the URLs for your REST service sitting in JavaScript code on the client, in theory anyone could check the URL for your call to, say, change your password.

How do you secure the service so that I can't check the URL and just try to call the REST service directly and affect other users?

A GUID user ID that is passed in might help, but is this the best/only method for securing your REST service from a client?

I have a form that I need to have two means of submitting the form. The first way is with the standard submit button. This works just fine. I also need to submit the form after the htm page has been printed using a button that calls a "printpage" function. This function prints the page, displays an alert and then is supposed to submit the form. It does everything except for submit the form. Any help figuring out why is appreciated.
The code for the htm page is shown below.

Doubt in AJAX response obj

I have a doubt in ajax.My code is

function constructResponse( req , funName)
{
if (req.readyState == 4)
{
if (req.status == 200)
{
var callBackFunction = funName +"(request)";
var newFunction = new Function("request",callBackFunction);
newFunction(req);
}
else
{
alert("There was a problem in retrieving the data:\n" +req.statusText);
}
}
}

I call this function at req.onreadystatechange .My doubt is when else was called.Because most of the time i got the alert msg.How to avoid the alert.

Thx,
Muthu.N

You didn't share remaining code. onreadystatechange[^] is right one which have you used.

I think the problem occurs somewhere out of this code. What's the value of req object? What did you get from req.statusText? Debug it, you could solve the issue.

Here Callback function[^] example from w3schools, check it out.

Script running multiple times

AnalogNerd10-Oct-13 10:49

AnalogNerd

10-Oct-13 10:49

I have a jQuery script that is listening for keydown on a textbox, like so:

JavaScript

$(document).ready(function () {
       $("#result").on('keypress', function (e) {
           ...
        });
 });

My problem is that I have written this for a site architected and hosted by a 3rd party. This site allows you to move modules around the page if you wish.

When my module is moved (sometimes! not all the the time) it appears as if the page creates more instances of my code. As a result the code in the keydown function fires multiple times.

A few things:
1. I put an alert in the document.ready and can see it pop up multiple times, so I know the page it loading more instances of my javasvript.

2. When looking in the debugger in IE or Firefox I can't find more than one instance of the script, but a breakpoint on the one I can find will be caught only once. Whereas the code does run multiple time. Again and alert in the function can be seen multiple times.

I've tried unbinding events from my textbox before binding, but it doesn't work.

Does anyone have any ideas of how I can prevent my code from being instantiated or triggered multiple times?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
