1、jsp代码
<div class="inputBox"><span id="tu" <c:if test="${pd == null || pd.CACHET == '' || pd.CACHET == null}">style="display: none;"</c:if>><img id="img" src="<%=basePath%>uploadFiles/carousel/${pd.CACHET}" width="210"/></span><input type="button" class="update" id="yyzz" value="上传" onclick="$('#YYZZFBSMJ').click();"><input type="file" name="YYZZFBSMJ" id="YYZZFBSMJ" style="display: none;" onchange="fileType(this)"></div>
2、js代码：
//过滤类型function fileType(obj){var fileType=obj.value.substr(obj.value.lastIndexOf(".")).toLowerCase();//获得文件后缀名if(fileType != '.gif' && fileType != '.png' && fileType != '.jpg' && fileType != '.jpeg'){$(obj).tips({side:3,msg:'请上传图片格式的文件',bg:'#AE81FF',time:3});$(obj).val('');}else{var reader = new FileReader();reader.readAsDataURL(obj.files[0]);reader.onload = function (e) { $("#img").attr("src",this.result);}$("#tu").show();}}
