定义一个长度嘛 Sting s="这是新闻标题哈哈哈哈哈哈哈哈"; int lengt=s.length(); if (int>10) s=s.substring(0,10)+"...";
substring(int beginIndex, int endIndex) Returns a new string that is a substring of this string. 用这个方法试下
我忘记说了 条件是不在服务器端进行 用css或脚本怎么弄啊？ 谢谢
刚好在人家blog（http://www.mysheji.com/blog/article.asp?id=304）上看到过 ====== <% function cLeft(str,n) dim str1,str2,alln,Islefted str2 = "" alln = 0 str1 = str Islefted = false if isnull(str) then cleft = "" exit function end if for i = 1 to len(str1) nowstr = mid(str1,i,1) if asc(nowstr)<0 then alln = alln + 2 else alln = alln + 1 end if if (alln<=n) then str2 = str2 & nowstr else Islefted = true exit for end if next if Islefted then str2 = str2 & ".." end if cleft = str2 end function %> ======不过不好意思，是VBS的
脚本还是一样的道理嘛。。<body onload="gai();"> <span id ="new1">我是新闻哈哈哈哈哈哈哈哈哈哈我行了吗</span> <body> <SCRIPT LANGUAGE="JavaScript"> function gai() { if (new1.innerText.length>10) { var s =new1.innerText.substring(0,10); new1.innerText=s+"..."; } } </SCRIPT>记得把你新闻的标题弄成<span>标签之间
