1.LI中內(nèi)容超過長(zhǎng)度后以省略號(hào)顯示的方法
???? <style type="text/css">
???<!--?
???li {
????width:200px;
????white-space:nowrap;
????text-overflow:ellipsis;?
????-o-text-overflow:ellipsis;?
????overflow: hidden;
????}
???-->
???</style>
???<ul>
???<li><a href="#">拉薩醬豆腐里腳手道路 上水道法撒旦法 </a></li>
???</ul>
2.鼠標(biāo)右鍵得屏蔽以及快捷鍵得評(píng)比
<body oncontextmenu="return false" onkeydown="bodyOnKeyDown()">
function bodyOnKeyDown(){
???
??? var actObjTagName = "";
?var actObjType = "";
?try{
??actObjTagName = document.activeElement.tagName.toLowerCase();
??actObjType = document.activeElement.type.toLowerCase();
?}catch(e){
?}
/*
??? //ENTER->TAB
??? if( event.keyCode==13 &&
??????? actObjType!="button" &&
??????? actObjType!="submit" &&
??????? actObjType!="reset" &&
??????? //actObjType!="textarea" &&
??????? actObjTagName!="a"){
??????? event.keyCode = 9;
??? }
*/
?//Function Key
??? if(event.ctrlKey){
??????? if( event.keyCode==78 || //CTRL+N
??????????? event.keyCode==87 || //CTRL+W
??????????? event.keyCode==69 || //CTRL+E

??????? }
??? }
??? if( event.keyCode>=112 &&? //F1,F12
??????? event.keyCode<=123 ){
??????? event.keyCode = 0;
??????? event.returnValue = false;
