JS强制换行
$(function() {$(".word_break").each(function() {var word = $(this).text();var step = 25;//步长var len = word.length; if(len > step) { var newWord = new Array(); for(var i = step; i < len+step; i+=step) { newWord.push(word.substring(i-step,i)); newWord.push("<br>"); } $(this).html(newWord.join("")); }});})?
