jstl根据字符串进行判断

惯例：

我是温浩然：

先说需求：

调用接口，传过json数据，对其进行解析，数据中，有url一栏，不确定是    mp4,还是jpg。

需要分析这个url，然后再页面上，根据类型显示图片或者视频。然后来看看图片或者视频是否合格。

先贴json中的数据：

                "noPass": false
            }
        ]
    }
}

下面开始：

贴代码

<c:forEach items="${taskpass}" var="task" varStatus="status">
						<tr>
							<td>${task.id}</td>
							<td>${task.cardId}</td>
							<td>
								<c:if test="${fn:contains(task.url,'.mp4')}">
									视频
								</c:if>
								<c:if test="${fn:contains(task.url,'.jpg')}">
									图片
								</c:if>
							</td>
							<td>
								<c:if test="${task.noPass==true}">
									审核未通过
								</c:if>
								<c:if test="${task.noPass==false}">
									审核通过
								</c:if>
							</td>
							<td>
								<div class="visible-md visible-lg hidden-sm hidden-xs btn-group">
									<button title="不通过" class="btn btn-xs btn-danger"  data-taskId="${task.id}"
											id="deleStageBtn" ><i class="icon-ban-circle bigger-120"></i></button>
									<button title="通过" class="btn btn-xs btn-info"  data-taskId="${task.id}"
										btntype="editStage"><i class="icon-check bigger-120"></i></button>
								</div>
							</td>
						</tr>
						</c:forEach>

就是这样。

PHP 字符串长度判断效率更高的方法

 在php里当需要判断一个字符串长度时,我们首先想到的是strlen()函数,不错,strlen()返回的就是字符串的长度,这样使用没有任何问题.不过,如果要从php程序优化的角度来看,使用strlen()判断字符串长度未免是最好的写法 有经验的程序员发现,php判断字符串长度,使用isset()在速度上比strlen()更快,执行效率更高. 即:    代码如下: $str = 'aaaaaa'; if(strlen($str) > 6) VS if(!isset($str{6})   用例子
