RegEx on Javascript; Checking for instances of one of multiple strings

Question

I have done a lot of server side form validation but until now, the only client side form validation I have done is to check for null/blank entries (e.g., if (value==\'\'||value

Answer 1

You can use the code below to check for validation not null, not blank, not undefined and not zero in javascript and jquery.

 function myFunction() {
    var data;  //The Values can be like as null,blank,undefined,zero you can test

     if(!(!(data)))
     {
     alert("data "+data);
     } 
     else 
     {
        alert("data is "+data);
    }

    }
