The Index property of each () of foreach and jquery using Jstl

In recent projects, interlaced color-changing problems have been used, with each of the Jstl foreach and jquery loops.

First JSTL technology. In addition to the commonly used Items,var, there is also a subscript attribute varstatus, starting from 0, is very convenient to use.

var= "Person" varstatus= "I" >        <c:if test= "i%2==0" > Do              Something         </c:if>            </c:forEach>

And again, each of jquery. There is also subscript, and as with Jstl's foreach, start from scratch.

$ (data). Each (function(i,m,n) {                // return subscript, starting from 0                alert (json.stringify (m)) ;    // returns the data itself                alert (n);            // undefined            });

With these two artifacts, the code will no longer be afraid of interlaced color change.
