Blank{font-size:18px;Font-weight:Bold;text-align:Center;padding:20px}</style><Scripttype= "Text/javascript"src= "Http://www.softwhy.com/mytest/jQuery/jquery-1.8.3.js"></Script><Scripttype= "Text/javascript">JQuery.fn.limit=function(){ var Self=$("Div[limit]"); Self.each (function(){ varobjstring=$( This). text (); varObjlength=$( This). Text (). length; varNum=$( This). attr ("Limit"); if(Objlength>num) { $( This). attr ("title", objstring); Objstring=$( This). Text (Objstring.substring (0, num)+"..."); } }) } $(function() {$ (document.body). limit ();}) </Script></Head><Body><DivID= "Best"> <DivLimit= " a">Ant Tribe welcome you, hope everyone is happy every day</Div> <DivLimit= "Ten">No one is born to be a master, such as by effort</Div> <DivLimit= " a">Every day is a new one, and everyone should cherish it.</Div> <DivLimit= " a">Only the current time is real, tomorrow will always be tomorrow</Div> <DivLimit= "Ten">The spirit of mutual help and the bosom of sharing are the most valuable</Div></Div></Body></HTML>
