I am new to jQuery and trying to learn it example by example In the below example, I am trying to call a servlet on an event of anchor tag click using jQUery Ajax. I have more than one anchor tag in my page and I want a different servlet to be invoked for each of them. If I use the id of anchor tag like $('#submit1').click as in below example it is not working. But, if I replace it with 'a' it is working which invokes the same servlet for both of anchor tags
