禁止页面右键点击及禁止f12调出控制台，但是存在兼容性问题，chrome下全功能，firefox下禁止f12失效，ie下全部失效，源码如下:
<script>
//禁止右键和f12
function click(e) {
if (document.all) {
if (event.button==2||event.button==3) { alert("你要干嘛");
oncontextmenu='return false';
}
}
if (document.layers) {
if (e.which == 3) {
oncontextmenu='return false';
}
}
}
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
}
document.onmousedown=click;
document.oncontextmenu = new Function("return false;")
document.onkeydown =document.onkeyup = document.onkeypress=function(){
if(window.event.keyCode == 123) {
window.event.returnValue=false;
return(false);
}
}
</script>
