  • not likely...different form elements need to be validated differently..!
  • Use JQuery,

    • The previous answer use jQuery is the best answer.

      If for whatever reason you don't want to use jQuery the alternative is as follows:

      Create a javascript function for checking the value of a field and return true of false based on wether or not the required field is checked

      Create an array containing all element names of the required fields you need to check

      create a loop iterating over every element name in the array and calling the function you created. If false break out of the loop and display an error message.

      Good luck. If nessescary PM me.

    • The best option is jquery but if you want to use your own way then use if else condition also very easy.
