jsp页面上截取

　　　　　　　　　　　　　　　　<c:choose><c:when test="${fn:length(ad.remark) > 80}"><c:out value="${fn:substring(ad.remark, 0, 80)}..." /></c:when><c:otherwise><c:out value="${ad.remark}"/></c:otherwise></c:choose>

js中截取

  function subTextContent(textContent, len){if(textContent != null && textContent != undefined){var tLen = textContent.length;if(tLen <= len){return textContent;}else{return  textContent.substring(0, len) + "...";}}return "";}

后台截取

  　　　　　　　　for(ArticleEntity articleEntity : categoryList){String content = articleEntity.getTextContent();if(content !=null  && content.length()>70){articleEntity.setTextContentSub(content.substring(0,70)+"...");}else {articleEntity.setTextContentSub(content);}}
