【javascript】JS实例——鼠标操作

1.禁用鼠标左右键

function click(event){
event = event||window.event;//考虑兼容性
    if(event.button == 2){ //单击鼠标为右键
        alert("禁止使用鼠标右键");
    }
    else{
        alert("禁止使用鼠标左键");
    }
}
document.onmousedown=click;  //绑定事件

2.鼠标移动时的坐标

window.οnlοad=function(){
      var mydiv = document.createElement("div"); 
      mydiv.setAttribute("id","hint"); 
      mydiv.style.position="absolute"; 
      document.body.appendChild(mydiv); 
      document.addEventListener("mousemove",function(e){
          var myhint = document.getElementById("hint");
          myhint.style.left= e.clientX+"px";
          myhint.style.top= e.clientY+"px";
          myhint.innerHTML=e.clientX+" ："+e.clientY;
      });
  }

3.禁止鼠标滚动（失败）

document.onmousewheel = function(){return false;}

function document.onmousewheel(){
    return false;
}

4.鼠标直接直接跳转百度首页

function newPage(event){
event = event||window.event;
    if(event.button == 2){
        location.replace("http://www.baidu.com");
    }
}
document.onmousedown=newPage;

IE8运行失败

5.鼠标放到图片上显示另一张图片

<script type="text/javascript">
function change(e){
    e.src="2.png";
}
</script>
<img οnmοusedοwn="change(this)" src="1.png"/>
