When A User Enters Information In Those Two Textboxes And Click On Submit, The Information Is Sent To A Function?
Oct 29, 2010
I have a HTML form containing two text box controls in it and a submit button. When a user enters information in those two textboxes and click on submit, the information is sent to a function in Javascript. In the javascript, the information from those textboxes is stored in a javascript variable. The problem is as follows:When I am inputting string text in the html text boxes and in the javascript when I am trying to print those values, it is giving me out an error saying NaN. However when i input integer values in the text boxes it is printing those numbers. Is there a conversion that I have to do for the string to be printed. I am new to Javascript and need your help. This is a basic code of Javascript. Below is the code that I have.
<html>
<script type = "text/javascript">
function square(form)
[code]....

I have a basic understanding of selecting elements and performing manipulations or effects, but I'm having real trouble grasping the basics of setting up variables, performing maths on variables and biggest of all, how you go about passing information from the HTML into a jquery function.
I have a site where clicking on any photo thumbnail brings up a full-screen lightbox to display the image full-size - I'm using the following to bring in the lightbox:
$(".photo").click(function(){
$("#lightbox").css({"visibility":"visible","z-index":"2"});
$("#lightbox").stop(true, false).animate({opacity:1},800);
});
This works just fine, I also have no problem re-assigning the SRC of a blank image within the lightbox to make sure the correct image renders, my problem is I just don't know how to generate or pass information into this function to begin with to act as a reference point so the code knows what image it should be displaying based on which thumbnail was clicked.
I don't need anything particularly clever, even if each thumbnail simply had a numerical figure associated with it (eg "4") which gave the function something to work with once it was fired - that would be enough.
I know how to do all this in regular JavaScript but I have to admit I'm finding the documentation for jquery really hard work, I'm having real problems grasping the fact that the functions aren't being triggered directly by the HTML.
Another solution would be to get the src of the image that was clicked on, split the string and pull out just the filename (ie 5.jpg) and then prepend a path to it for the final full size image ( largeimage/ + 5.jpg).
I know there are probably pre-made scripts for this kind of thing but I'd like to try and avoid them if possible.

I would like to put a welcome message on one of my sites... something like "welcome username!" with the username being the login name that that person used to login to their computers.
Is it possible to gather this information using client-side js? if not, how can i accomplish this without having each person enter their name upon entering the page?

I am having some trouble with creating cookies and getting them to work for an onclick event. What I am trying to do is create a button to store cookies containing all user information with an alert message and set the expiration date one day after the visit. (This is just a project I am working on to help me understand how to create cookies.)Below is the cookies code I came up with but it doesn't seem to be functioning at all.

+ Party at the Party Place
+ Concert at the Stadium
+ Stand-up Comedy at the Funny Place
So we have three "links" above, each listing an "activity". However, I want to provide more details about each activity. I wish to provide more details when the user clicks on the link. Like so:

My goal is to have the four Javascript buttons toggle the four pictures on and off. I know my css is right. Since everything is placed where I want it and is hidden when the page loads. I believe everything in my html is right. I am reasonably sure I am passing the img id using the onclick function correctly. I think my problem is in the Javascript file. I am thinking I am not passing it into the function correctly.

I have been successfully using the following "myAjax" function to load text file information from the server.
ajax.js:
After I load the text file, I store the text "records" into an array by doing something like this:
Where the '}' character is my record delimiter. It could just as easily be ' ' or ' ' or the like.
Again, I am not having any problems doing it this way as it suits my current needs.
Now the question(s)
1. Does the call to read the text data from the external file always read in the entire contents or can I read one line or delimited record at a time and store it to the array directly without the text storage?
2. If the text is always read completely (my suspicion), can I safely delete the "TextInformation" after I convert to the array format? Is there any memory penalty for doing it this way as the text information can be somewhat lengthly and I don't like the idea of having doubled memory usage when I only need the information in array format anyway?
This is the idea I am considering, but I don't know if there are drawback to this method of if there is a better way to accomplish the task.

Is there something that will update as soon as the user changes information in a textbox as appose to what onChange does, which is update once the focus has been taken off of the textbox? I am writing a custom cart and I am using AJAX to update the price according to how many they are ordering, I was hoping to have it update the price as soon as the user put in the volume, but it doesnt update until the user clicks somewhere else on the page.

I'm trying to set a cookie when a user enters a page. The cookie is for youtube to make videos default to widescreeen.
I know that the cookie name is wide, the value should be set to 1, the domain should be .youtube.com but I dont know how to do it properly. Ive been trying to set it from a link, so when a user clicks the link and it opens in a frame, the cookie is set so that the youtube video opens as widescreen in the frame.
however, whenever I look at my list of cookies, it isnt being created.
is this the best way to do this?
(I found how the cookie is created by checking the values of the cookies when I pressed the 'right turn' arrow on a youtube video)

User enters integer values into an editable gridview. JS is meant to keep a running total in the gridview footer template while user enters the values. User clicks 'Save' button. The values are saved to database table.
Problems:
1. JS does not keep a running total if there is already values saved in a database table. (Explaination: If user clicks 'select all', the previously added values are loaded. Can edit these and running total works. But, if user is entering numbers for the first time into a blank editable gridview, the js does not work).
2. Cannot access label in gridview footer template. 'Object reference not set to an instance of an object'. If label is placed in normal gridview row, it is fine. However, it needs to be in the footer.
javascript function
Meant to be in footer template but placed in normal row for now:

I am working on a online video portal build on flash/actionScript.
If I enter a url of a video when another video is playing, it doesn't playing the new video but it keeps on playing the old video. The reason I think is as it is a RIA, it doesn't refreshes the page and looks for a flash object and its already cached so it doesn't makes any http request in order to play the new video.
So I am planning to claer the cache.
how to clear the cache when a user enters something in address bar and press enter key?
