<!--组合键: -->IE的键盘监听最多只能作用于document上(window我试过不行)如果内嵌了iframe并且你的焦点在iframe上,那么按键无效
这里我用CTRL+Q写的例子:
function test(){ if(event.ctrlKey&&window.event.keyCode==81){ myalert(); }}
<!--禁止网页右键: -->
document.body.oncontextmenu=function rightClick(){ window.event.returnValue= false;}
<!--禁止网页另存为: -->
<noscript><iframe src=*.html></iframe></noscript>
<!-- 禁止选择文本: -->
<script type="text/javascript">
var omitformtags=["input", "textarea", "select"]
omitformtags=omitformtags.join("|")
function disableselect(e){
if (omitformtags.indexOf(e.target.tagName.toLowerCase())==-1)
return false
}
function reEnable(){
return true
}
if (typeof document.onselectstart!="undefined")
document.onselectstart=new Function ("return false")
else{
document.onmousedown=disableselect
document.onmouseup=reEnable
}
</script>
<!-- 禁用右键: -->
<script>
function stop(){
return false;
}
document.oncontextmenu=stop;
</script>
