How to get the function to work.
I have this script that is supposed to check if a number the user guesses is the same as the randomly generated number.Problem is that the random number generated at the start of the program keeps on changing everytime I click on the "Check if I'm right" button, the random number gets generated again and I never ever get to reach the correct answer

I've wrote a very similar function that works perfect but no matter what i do here, the result is always the same. I can't seem to enter a 2 digit number in the second box for weight and therfore won't work. It seems to work fine for up to 9 lbs though.

I have to do a project to figure out a person's grade. I am having trouble though, the user has to enter the number of exams, projects, etc. so it cannot be set. How would I do this with arrays? i.e., if I made it exams = new Array(4), this would limit the person to 4 exams even if he/she has more they want to enter in.

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.
View 2 Replies View RelatedI 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.

I need help with javascript regular expressions.I have a text box in which user can enter only 4 types of values.
1) Varchar(n) where 0 < n <=80. Ex: Varchar(20)
2) Char(n) where 0 < n <=80. Ex: Char(20)
3) numeric(x,y) where x>y and 1<= x <=35 and 0<= y <=15. Ex: numeric(20,6)
If the text box value doesnot match this pattern, we should throw him alert message.

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 intern page with a form. User should enter their data and send the form. Some data from the user is stored in a database (name,phone). I want to make the form easier and complete the form with data from the database. The user should only enter his personal-number. How can i solve this with jquery? Is there any plugin?

How would I add an if statement to limit the number input by the user to less than 20?
View 4 Replies View RelatedFor some reason, IE8 insists on submitting an HTTP GET request when the user presses "enter" when inside of an <input> element.It's a rather curious thing because I have an <input type="submit" /> that has an event for "click" that contains the following code:
event.preventDefault();
event.stopImmediatePropagation();
This works on Firefox - if the user presses "Enter" inside of an input element on the form, the submit button will not execute. But on IE, it does. However, if the IE user "clicks" the submit button, it does the right thing.Do I have to also override keydown events too and stop those? Why does Firefox and IE work differently here?

How would I go about creating a random number between 1-50 that COULD include whole numbers, decimals to the tenth, hundredth and the thousandth place?
Ex) 2.145, 3, 5.8, 41.002, 10.12, 7, 18.023, 33.2
Also, if the only way to do it is to put trailing zeros to the thousandth place that's fine as well
Ex) 2.145, 3.00, 5.800, 41.002, 10.120, 7.00, 18.023, 33.200
I use the following to verify that a user has entered a number between 0 and 99 in a form:
It seems to work fine in all browser / machine combos except Firefox on a Mac, when entering 0 returns false (I don't know if entering other numbers also returns false.)
