Clear Cache When A User Enters Something In Address Bar And Press Enter Key?
Sep 10, 2007
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?
I have a client that wants a site for people who are potentailly being abused, often by partners they live with.
He is under the impression that it is possible for there to be a "Button" that deletes the cache when the user presses it rather than going through the procedure of clearing the cache. I can see why this would be a goog thing to have, and wondered of js (or perhaps php might be the way to go)
how to clear browsers' cache with javascript? .. so users will unable to go to previous page after they logged out.. I tried to add <meta http-equiv="Pragma" content="no-cache"> on head section of my page1.jsp .. but it does not work
OK, so I have an AJAX app and am using browser caching to reduce the number of server calls. However, I wanted to be able to clear the whole cache for the browser if the version of my AJAX app has changed.
My plan is to have the version number stored in a cookie on a user's machine. The first thing my app then does upon load is check the version number of the javascript to the version number of the cookie and if they are not the same clear the cache.
I am trying to submit form on press Enter but its does not work in IE8, works in chrome, and mozilla, I dont know what I made the mistake in my coding.
Wondering if there's a better way than what I'm doing to disable that when a user presses Enter, the form is submitted.
I'm catching the enter key onkeydown events. And it works fine on input boxes but I noticed that if a user selects something on a drop down menu and presses the enter key, the form is also submitted. As far as I know drop downs don't have an onkeypress event.
Is there a way to cancel form submission when the Enter key is pressed? Or any ideas how to catch this event on a drop down?
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 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)
I need to learn how to clear form fields when a user clicks on them. Here is the site in question: [URL] They used to work, but then I changed the field value and now it doesn't work on some of the fields (whichever ones I changed). Here is a link to the .js file:[URL]
I want to make it so if i have several text boxes only one number can be entered once. So if i type the number 15 in the first text box and type 15 in the second text box an error will occur saying you cant enter the same number twice.
The application works fine but it makes the user enter the answer twice before it brings up the question "Would you like to continue?". I thought the fix would be to just call "myMH.checkAnswer(studentAnswer);" straight from the method in the "appclass" but that didn't fix it I m so lost on this problem. This problem most likely is right in front of my face but don't see it lol. I have another question as well but I think if I get this one figured out first it might answer my other one.
I am new to JavaScript and was wonder how I would go about creating a form to allow the user to enter various words, one at a time. These words are added to an array and displayed in the page using the textarea form element. Each time a new word is entered, it is added to the array, and then the array is sorted in alphabetical order before the words in the array are displayed in the textarea, one per line. I have tried lots and lots of different methods to accomplish this, and I can get it half working when I use the alert function, but I need this to display on the page in a textarea rather than in an alert box, I tried to get it to write to the page using a document.write function, but like I said I am new to JavaScript and unfortunately cant get any of it working.
