Here is what I have so far. I cant get it to work.
This application stores the last name, first name, and score for one or more students and it calculates the average score for all of the scores that have been entered.
When the user clicks on the Clear button, this application clears the score data from this application.
When the user clicks on the Sort button, this application sorts the data in alphabetical order by last name.

How should I start learning javascript. From where should it, Any book, Video tutorial etc. I just have 3 months and want to learn javascript to basic or intermediate level not advanced level in 3 months. Please guide me
|
|
|
|
|
|
One really nice tutorial I found is here[^].
Click on the Classroom link, and get going.
|
|

|

3 months are fair enough to learn JavaScript. First learn some basic concepts of JavaScript like how to manipulate DOM, Event binding, functions in JavaScript.I will suggest learn some jQuery for DOM manipulation. After this start creating some small Application like calculator.Gradually you will understand how things works in JavaScript.
After that you can try some books like JavaScript good part. 
|
|
|
|
|
I recommend "learning by doing", which, in your case, means not reading lots of text about the intricacies of the language (like in most JS programming books), but rather read the minimum necessary to start programming your first app. This approach is implemented in my tutorial book Engineering Front-End Web Apps with Plain JavaScript.
|
|
|
|
|
You can start with 'Object-Oriented javascript by Stoyan Stefanov'. Very simple language and start from basics. A must have book for any javascript programmer.

I am brand new to coding of any kind. I am reading W3schools, Javascript String Methods, and one of the functions I don't understand is what is the function/purpose of Extracting String Characters?
These two codes are particularly unclear to me charAt() and charCodeAt(). When would they be used?
|
|
|
|

Member 11446034 wrote: charAt() and charCodeAt()
The charAt function[^] returns the character at the specified index. For example, if the string contains "Hello", s.charAt(0) will return "H".
The charCodeAt function[^] returns the numeric Unicode value of the character at the given index. For example, if the string contains "Hello", s.charCodeAt(0) will return 72, which is the Unicode value that represents an uppercase "H".
List of Unicode characters[^]
Member 11446034 wrote: When would they be used?
They would be used when you need to extract either a character, or the Unicode value of a character, at a particular index in a string.

Hi,
I am new to jQuery, ajax and signalR.
I have this code in Popup.js file, I don't know what it is and I don't know how it executes, but I can understand that this code is to open popups one with close button and another without close button, because I commented and ran it, but I want to have the control over setting which popup to have close and which not. I am trying my best and placing the code in the aspx and ascx files.
I am not understanding, can some one please help me with this, and if I want to overwrite this same functionality in the local popup, page or user control how can I do that?
Any help code snippet, link or even suggestion would be greatly helpful
var control ={
---
convertLinkToPopupWithClose: function (event, informParentOnClose) {
return ELMS.WebControls.Popup.convertLinkToPopup(event, { showClose: true, closeInformsParent: informParentOnClose | false });
},
convertLinkToPopupWithoutClose: function (event, informParentOnClose) {
return ELMS.WebControls.Popup.convertLinkToPopup(event, { showClose: false, closeInformsParent: informParentOnClose | false });
},
----
}

If you know which block of code it is complaining about then please edit your question, remove all the other stuff, and then format what's left for easier reading.

Hi All,
I am maintaining an application in which in client side script it is adding a button as below in which it showing some axd file, can some one explain me how can I go to this button click event?
When I went to the xxxxx/Prescreen folder location I don't find any file named Image.axd, what can I do to handle this situation.
Can anybody please help me in finding what exactly it means? any link, any suggestion or code snippet would be very helpful, all I want is to go and see what it doing when we click the "btnAdditionalFamilyQuestions" button.
<input type="button" name="btnAdditionalFamilyQuestions" id="btnAdditionalFamilyQuestions" value="Additional Family Questions" style="width: 215px;
background-image: url(http://localhost/xxx/xxxxx/Prescreen/Image.axd?r=0&g=178&b=214&p=20&h=25&t=Additional%20Family%20Questions);">
Thanks in advance.

Is Google not working where you are? The first result of searching of "axd": What is an .axd file? [Stack Overflow][^]
An .axd file isn't a physical file on disk; it's an IHttpHandler (or IHttpHandlerFactory) registered in the web.config file.

Sorry, may be I was little quick to ask but I have been googling, but one thing I am not able to understand that how can I debug a file or code that's using axd extension, very unfortunate thing is as I have been writing lot of server side code for a while I am used to debug the code.
Can you please help me in that aspect, just in the below button click event it is opening a popup, how can I understand or debug what is it trying to do in that button click, what I understood is all that information can be obtained by that .axd file, but I am not sure how to crack it, please help me, if I wrongly understood please correct me.
<input type="button" name="btnAdditionalFamilyQuestions" id="btnAdditionalFamilyQuestions" value="Additional Family Questions" style="width: 215px;
background-image: url(http://localhost/xxx/xxxxx/Prescreen/Image.axd?r=0&g=178&b=214&p=20&h=25&t=Additional%20Family%20Questions);">
Thank you.

If you look in your web.config file - either under system.webServer/handlers or system.web/httpHandlers, depending on whether your site is using the Integrated or Classic pipeline - you will see an <add ...> element with the path set to "image.axd".
The type attribute on that element will tell you which class handles the image.axd requests.
Assuming you have the source code for that class, you should then be able to set a breakpoint within the ProcessRequest method and debug it.

http://jsfiddle.net/Trolstover/m1uwrzz1/1/[^]
Here is a sortable list which i made , but the question is, how can i invoke ondrop event on mouseover? Basicly i want to show position of selected(dragged) element (where it would be if you actually dropped it there)
|
|

|

The following is my HTML page. My problem is with invokeService(). It correctly determines the body and places it in data - but then it never sends the data. Fiddler shows no JSON data was sent. The Success routine is called but the data is null (as would be expected with no input data).
Can anyone tell me what I am missing or did wrong. How do I send the JSON to the service?
Thanks Brent
