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); } }
