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.
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.
