Die Verwendung und Grundlagen der jQuery-Rückruffunktion (callback)_jquery

Lass uns zuerst den Code veröffentlichen

Code kopieren Der Code lautet wie folgt:

   
       
       
       
   

   
        点击开始动画
       

        <script> <br>             $(document).ready(function(){<br>               $("bouton").click(function(){<br>                 var div=$(".box");<br>                 div.animate({hauteur : '200px',opacité :'0.4'},"lent");<br>                 div.animate({width:'200px',opacity:'0.8'},"lent");<br>                 div.animate({hauteur : '100px',opacité :'0.4'},"lent");<br>                 div.animate({width:'100px',opacity:'0.8'},"lent");<br>                 div.animate({right:'100px',opacity:'0.8'},"lent");<br>                 div.animate({bottom:'100px',opacity:'0.8'},"lent");<br>                 div.animate({left:'100px',opacity:'0.8'},"lent");<br>                 div.animate({top :'100px',opacity:'0.8'},"lent",function(){<br>                     alert("Le paragraphe est terminé");<br>                 });<br>               });<br>             });<br>         </script>
        <script><br>             $(document).ready(function(){<br>                 $("bouton").click(function(){<br>                     var div=$(".box");<br>                         div.animate({hauteur : '300px',opacité :'0.4'},"lent");<br>                         div.animate({width:'300px',opacity:'0.8'},"lent");<br>                         div.animate({hauteur : '100px',opacité :'0.4'},"lent");<br>                         div.animate({width:'100px',opacity:'0.8'},"lent",function(){<br>                     alert("Le paragraphe est terminé");<br>               　　　　  });<br>                     });<br>                 });<br>             });<br>         </script>
   

所谓的回调函数，其实就是在 vitesse 或 durée 参数可以设置许多不同的值，比如 "lent", "rapide", "normal" 或毫秒  后面再添加函数，显示相对应的内容，以提示网民
