Effect of making light rod with JavaScript and jQuery

Differences and steps of adding CSS style using javaScript and jQuery

Using javaScript to make light rod effect

--The first is javaScript

<script>
    $(function () {
      var lis = document.getElementsByTagName("li"); // Definition DOM Variable acceptance label is li Elements of 
      for (var i = 0; i < lis.length;i++){      
        lis[i].onmouseover = function () {
          // Mode 1
          //this.style.backGround = "pink";   //1 Note that you can only use it here this Method acts as a for Loop the current traversal item 
          //this.style.fontSize = "50px";   //2 , likewise style The following additional styles can only be named by camel nomenclature 
          // Mode 2
          this.style.cssText = "background-color:red;font-size:50px";
        };
        lis[i].onmouseout = function () {
          // Mode 1
          //this.style.background = "";
          //this.style.fontSize = "20px";
          // Mode 2
          this.style.cssText = "background-color:;font-size:20px";
        }
      }
    });
  </script>

Compared with the two methods,. cssText is relatively simple

Using jQuery to make light rod effect

 <script>
    $(function () {
      $("li").hover(function () {                  // Compound events are called here   Simulate mouse hover events 
        $(this).css({"background-color": "red","font-size":"50px"});
      },
      function () {
        $(this).css({ "background-color": "", "font-size": "20px" });  // Direct append CSS Style 
      }
      );
    });
  </script>

Compared with javaScript, jQuer code is more flexible and simple. (There is automatic traversal effect in jQuery, which saves circulation.)
