用setTimeout模拟QQ延时提示框

 

很简单的代码，不多解释，一看就懂。

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<style>
    #div1{width:50px; height:50px; background:red;}
    #div2{width:200px; height:150px; background:grey; display:none;}
</style>
</head>

<body>
    <div id="div1"></div>
    <div id="div2"></div>
    
    <script>
        window.onload = function(){
            var div1 = document.getElementById("div1");
            var div2 = document.getElementById("div2");
            var timer = null;
            
            div1.onmouseover = function(){
                clearTimeout(timer);
                timer = setTimeout(function(){
                    div2.style.display = "block";
                },500);
            };
            
            div1.onmouseout = function(){
                timer = setTimeout(function(){
                    div2.style.display = "none";
                },500);
            };
            
            div2.onmouseover = function(){
                clearTimeout(timer);
                timer = setTimeout(function(){
                    div2.style.display = "block";
                },500);
            };
            
            div2.onmouseout = function(){
                timer = setTimeout(function(){
                    div2.style.display = "none";
                },500);
            };
        };
    </script>
</body>
</html>
