推荐答案

(function () {
var showChar = 90, showtxt = \"more\", hidetxt = \"less\";
(function () { var showChar = 90, showtxt = "more", hidetxt = "less";


('.more').each(function () {
var content =
('.more').each(function () { var content =


(this).text();
if (content.length > showChar) {
var con = content.substr(0, showChar);
var hcon = content.substr(showChar, content.length - showChar);
var txt = con + '<span class=\"dots\">...</span><span class=\"morecontent\"><span>' + hcon + '</span>&nbsp;&nbsp;<a href=\"\" class=\"moretxt\">' + showtxt + '</a></span>';
