JavaScript - Howto
Looking at http://www.directv.com for example:
You highlight over the specific sections of their navigation bar, such as "What is DIRECTV?" and it displays sub-options below the section. How would one go about this, and what would the best way to do this? I'm sorry if this wouldn't even be JavaScript; my knowledge doesn't exceed simple coding. Also, I've heard you should use CSS image rollover effects instead of JavaScript for image highlighting because it prevents there from being a second where no image has loaded. How would I prevent that in this case? And a completely unrelated question: Looking at the source of directv's website, there is a LOT of unneeded entering. Is there any reason they did that? Just curious ;p Thanks Similar TutorialsHello! I am trying to make a form, with different options and, upon hitting submit, a new page will open with the created URL. for example: 1) Enter the URL: user enters: http://www.supertown.com 2) Enter the city: user enters: Chico 3) Enter the state: user enters: CA [SUBMIT] Then the following window opens: http://www.supertown.com?city=Chico&state=CA Ive been trying to figure this out for over an hour...AHH! i am making a payslip but i do not know how to correct the error : =grosspay(int,int) in payslip3 cannot be applied to (int) =netpay(int,int) in payslip3 cannot be applied to (int) =totaldeduction(int,int) in payslip3 cannot be applied to (int) also whenever I type the value and push the button in order to calculate the answers, the inputs are being cleared...... here is the code......
