Imagine you have image1.jpg and image2.jpg when a user selects image1.jpg the cookie needs to store image1 and load page2.html If the user selects image2, then page2.html still needs to load but store the word image2 in the cookie.

Hi I have been trying to create a form using Django for a very long time but have not been able to get it to look the way I want. Someone suggested to me that I should use Javascript (Jquery) to do this. Here's what I want to do. For the form I want, there are certain statuses at the bottom, like "Done", "Incomplete" and etc. When the form is filled in, the person will click on one of these statuses. What I want this button to do is to save the page/form and also to generate a few new links relating to the status selected. For example, if the person selects "Done" this should save the form and generate two new buttons. One that says "Close" which would take you to the home page, and one that says "Continue" which would take you to the next form. My problem is that I'm new to Django and have no experience with Javascript. So if anyone could help or give me hints that would be greatly appreciated. Friends i'm in a dire situation only have wednesday to submit ..so heres the problem....i have a course work assigment where i have to hardwire Hardware items and their item codes description and prices and ask the user to input their name address the itemCode and quantity nad then creat an invoice which looks like this HARDWARE ITEMS CODE DESCRIPTION UNIT PRICE K16 Wood screws, brass, 20mm, pack of 50 $ 7.75 D24 Wood glue, clear, 1 litre $ 5.50 M93 Sandpaper, medium grade, 100 sheets $10.25 M94 Sandpaper, fine grade, 100 sheets $14.75 PLACE YOUR ORDER!

SHIPPING: 20.75 VAT at 20% 4.15 TOTAL TO PAY: 24.90 I HAVE ALREADY COMPLETED THIS BY MYSELF AND GOT IT WORKING WITH NO PROBLEM ..But my problem is that the teacher wants us to TEST FOR NULL ENTRY meaning if the user enters the wrong Itemcode or no ItemCode at all and give an sensible output for that case ..... she wants us to put it in a method after main and then call it in main using a do while loop so my method looks something like this Code: public static boolean isSomethingCorrect(String itemCode){
if(itemCode.equals("")||itemCode.equals(null)){
System.out.println("A sensible output");
return true;
}//close if
return false;
}
}
// and i have to implement it where i ask the user for input using a Do while loop in this area Code: //a do while loop to test null code entry
do{
System.out.println("Please select a code from the list");
String itemCode= br.readLine();
System.out.println("Please enter quantity of items " +itemCode);
String itemQuantity= br.readLine();
int quantity= Integer.parseInt(itemQuantity);

Hi Guys, I am implementing this Javascript in my summer internship. What I want to do is, 1) Show a Pop up alert with a Countdown timer( 10, 9, 8, 7 ....) after 5 minutes. 2) If user doesn't click "Ok" within the time, the page will automatically Redirect to another page. Eg- Login Page. 3) If the User clicks the "Ok" button the Page will not get re-direct. 4) Also, once the Timer countdown completes and the page redirection is done, the User when he will see the Login page will see an alert box saying. 'Your session has expired, plz login again' he clicks 'Ok' and Login again. I am very new to this Java script, but need to finish this project.
