Q1. write a function called countAS that will take a string as input (using a prompt dialog box,prompt the user or the string).the string must contain only a's,b's and c's e.g. "abccbbaa" or "aaabbbccc" if any other letters are present apart from the letters a b c, output an alert dialog box with an error message and prompt the user again to input a valid string.count the number of a's the numbers of b's and the numbers of c's entered and display the count for each as well as a total count of all the characters within the string .
for example if the string was abbcc output should be as follows:
the total count is 5 characters
The Number of a's is 1
The Number of b's is 2
The Number of c's is 2
Q2. write a code that uses an event handler to display an alert dialog box with the message 'hello to you all' when a user clicks a link in a html page which links to the school of computing website.
You could use a regular expression to first check if the string is valid. If it is, then loop through the string and count how many a b and c's you have. If it isn't the prompt the user for another string.
Another option is to not use a regular expression, but loop through the string using charAt(). At each character use a switch() block to count the a b and c letters and if the char is not a valid character reset the a b c counters to 0 and prompt the user for another string.
Post the code you have so far and we can try to help you get it working.
But if the op doesn't get any help here, they most probably will on another website.
I don't have any issues helping people with queries (whether it is homework or not) if I see they are making a genuine effort to do it themselves first
its not homework im trying out a bunch of qusetions and because im new at this sort of stuff i am finding it hard to understand and yes i have read all the rules and stuff but if this website is not for helping others than why even have it.i was just looking for some help and so i thought this was the right place to ask any questions or problems that i am having.
The answer is the same as before. If you show us the code you yourself have written we will be happy to correct or improve it, but you must make a genuine effort yourself.

so is this right for the second question?
