<style>
#div1 {width:100px; height:200px; border: 1px solid red; display: none;}
</style>
<script>
window.onload = function() {
    var oBtn = document.getElementById('btn');
    var oDiv = document.getElementById('div1');    
    oBtn.onclick = function(ev) {
        var ev = ev || event; //事件对象的浏览器兼容        
        ev.cancelBubble = true;//阻止当前对象的当前事件的冒泡        
        oDiv.style.display = 'block';
    }    
    document.onclick = function() {        
        oDiv.style.display = 'none';  //点击除了oBtn以外的元素都隐藏
    }    
}
