javascript开发系列(面向对像)

javascript中的面像对像。

请看代码，下面弹出一个对话筐。

  <script type="text/javascript">
        function win(w, h,,url)
         {
            this.width = 100;
            this.height = 300;
            this.time = 10;
            this.url = url;
            this.openWin = function()
                 {
                  var iTop = (window.screen.availHeight) / 2;
                  var iLeft = (window.screen.availWidth - 10 - w) / 2;
                  window.showModalDialog('open.htm', '', 'dialogHeight=' + this.height + ',dialogWidth=' + this.width + ',help=0;status=1;scroll=1');
              }
         }
         function getWin() {
             var objwin = new win(100, 100,  'open.html');
             objwin.openWin();
          
         }
         window.onload = function() { getWin(); }
       
    </script>

 

另外。js中的函数，相当灵活，可以存储于变量，对像，属性，方法中。等
