二、 初始化设置:
$("#uploadfile").fileinput({
language: 'zh', //设置语言
uploadUrl:"http://127.0.0.1/testDemo/fileupload/upload.do", //上传的地址
allowedFileExtensions: ['jpg', 'gif', 'png'],//接收的文件后缀
//uploadExtraData:{"id": 1, "fileName":'123.mp3'},
uploadAsync: true, //默认异步上传
showUpload:true, //是否显示上传按钮
showRemove :true, //显示移除按钮
showPreview :true, //是否显示预览
showCaption:false,//是否显示标题
browseClass:"btn btn-primary", //按钮样式
dropZoneEnabled: false,//是否显示拖拽区域
//minImageWidth: 50, //图片的最小宽度
//minImageHeight: 50,//图片的最小高度
//maxImageWidth: 1000,//图片的最大宽度
//maxImageHeight: 1000,//图片的最大高度
//maxFileSize:0,//单位为kb,如果为0表示不限制文件大小
//minFileCount: 0,
maxFileCount:10, //表示允许同时上传的最大文件个数
enctype:'multipart/form-data',
validateInitialCount:true,
previewFileIcon: "",
msgFilesTooMany: "选择上传的文件数量({n}) 超过允许的最大数值{m}!",
}).on("fileuploaded", function (event, data, previewId, index){
});

方法名 |
参数 |
描述 |
fileerror |
|
异步上传错误结果处理 $('#uploadfile').on('fileerror', function(event, data, msg) {
}); |
fileuploaded |
|
异步上传成功结果处理 $("#uploadfile").on("fileuploaded", function (event, data, previewId, index) {
}) |
filebatchuploaderror |
|
同步上传错误结果处理 $('#uploadfile').on('filebatchuploaderror', function(event, data, msg) {
}); |
filebatchuploadsuccess |
|
同步上传成功结果处理 $('#uploadfile').on('filepreupload', function(event, data, previewId, index) {
}); |
filebatchselected |
|
选择文件后处理事件 $("#fileinput").on("filebatchselected", function(event, files) { }); |
upload |
|
文件上传方法 $("#fileinput").fileinput("upload"); |
fileuploaded |
|
上传成功后处理方法 $("#fileinput").
|
filereset |
|
|
fileclear |
|
点击浏览框右上角X 清空文件前响应事件 $("#fileinput").on("fileclear",function(event, data, msg){ }); |
filecleared |
|
点击浏览框右上角X 清空文件后响应事件 $("#fileinput").on("filecleared",function(event, data, msg){ }); |
fileimageuploaded |
|
在预览框中图片已经完全加载完毕后回调的事件 |
(1) 当点击上传后,报错,提示你必须选择最少X个文件上传。
错误原因:html中input标签元素属性:data-min-file-count="2" 设置为X个文件,限制上传文件数。
备注:图片上传比例判断
$("#imgFile").fileinput({}).on('fileimageloaded',function(event,previewId){
var img = $('#'+previewId).find('img')[0];
if (img.naturalWidth!=img.naturalHeight) {
alert('图片尺寸必须1:1');
image_check = true;
$('.fileinput-remove').click();
}else{
image_check = false;
$('.fileinput-upload').show();
}
})
$("#imgFile").fileinput({
language : 'zh',
//uploadUrl:'../../module/uploadMod/index.php?c=upd&a=fileInputUpload&dir=image',
showUpload: false, //是否显示上传按钮
showCaption: false,//是否显示输入框
showRemove: true,//是否显示删除按钮
dropZoneEnabled: false,
showClose:false,
showDrag: false,
//initialPreviewShowDelete:false,
browseClass: "btn btn-primary",
allowedFileExtensions: ['jpg', 'png', 'gif'],
previewFileIcon: "",
overwriteInitial: false,
initialPreviewAsData: true,
//initialPreview: [],
//initialPreviewConfig:images_arr_info,
fileActionSettings:{
showZoom: true,

}
}).on("fileuploaded", function(event, data,previewId,index) {
var data = data.response;
image = JSON.stringify(data);
$("#topImg").hide().parent().hide();
$('.fileinput-upload').hide();
}).on('filebatchselected', function(event, files) {
if(files.length<=0){
$('.fileinput-upload-button').hide();
}else{
$('.fileinput-upload-button').show();
}
}).on('fileimageloaded',function(event,previewId){
var img = $('#'+previewId).find('img')[0];
if (img.naturalWidth!=img.naturalHeight) {
alert('图片尺寸必须1:1');
image_check = true;
$('.fileinput-remove').click();
}else{
image_check = false;
$('.fileinput-upload').show();
}
});
$('.fileinput-remove').on('click',function () {
image = '';
$("#topImg").val('').show().parent().show();
$('.fileinput-upload').hide();
})
六 我的例子:
js端
$('#input-b2').fileinput('destroy');
$("#input-b2").fileinput({
language: 'zh',
uploadUrl: '/' + namespace + '/a/alarmPrecept/alarmPrecept/public/fileupload',
showPreview:false,
showRemove: true,
showUpload: false,
showCancel: false,
showUploadedThumbs: false,
autoReplace: true,
maxFileCount:1,
mainClass: "",
browseClass:"btn btn-success"
});
var fileArray = $('#input-b2').fileinput('getFileStack');
if (fileArray.length > 0) {
$('#input-b2').fileinput('upload');
$('#input-b2').on('fileuploaded', function(event, data, previewId, index) {
if (data.response.status==2000) {
$.ajax({
url: '/' + namespace + '/a/alarmPrecept/alarmPrecept/publish',
type: 'POST',
dataType: 'json',
data: {
c0919id: alarmPreceptId,
precepttype: rowdata.precepttype,
preceptname: rowdata.preceptname,
startTime: startTime,
endTime: endTime,
filePath: data.response.filePath,
importc0919id: alarmPrecept,
preceptname: rowdata.preceptname
},
success: function (result) {
if (result.status == '4011') {
dialog("error", result.message, 1000);
return;
} else {
dialog("success", result.message, 1000);
$('#preceptpublish-modal').modal('hide');
precept_table.ajax.reload(null, false); //重新加载数据
}
},
error: function (result, status, xhr) {
dialog("error", "发布失败", 1000);
}
});
} else {
dialog("error", data.response.message, 1000);
}
});
}
html 端:
文件上传:
业务端:
@RequestMapping("fileuploadGXJ")
@ResponseBody
public Map fileuploadGXJ(@RequestParam("input-b2") CommonsMultipartFile commonsMultipartFile,HttpServletRequest request){
Map map = new HashMap();
if(commonsMultipartFile.isEmpty()) {
map.put("status", "4011");
map.put("message", "文件为空,上传失败");
}
String filePath = Global.getConfig("fileinput");//参数1
String fileName = commonsMultipartFile.getOriginalFilename();//参数2
String dateDir = LocalDate.now().format(DateTimeFormatter.ofPattern("yyyyMMdd"));//参数3
StringBuilder sBuilder = new StringBuilder();
sBuilder.append(filePath).append(File.separator).append(dateDir).append(File.separator).append(fileName);
System.out.println("上传信息 = "+sBuilder);
File file = new File(sBuilder.toString());
if(!file.getParentFile().exists()) {
file.getParentFile().mkdirs();
}
try {
InputStream inputStream = commonsMultipartFile.getInputStream();
OutputStream out = new FileOutputStream(file);
byte[] buffer = new byte[1024 * 1024];
int len = 0;
while((len = inputStream.read(buffer)) !=-1) {
out.write(buffer, 0, len);
}
out.close();
inputStream.close();
}catch(IOException e) {
e.printStackTrace();
}catch(Exception ee) {
ee.printStackTrace();
}
map.put("status", "2000");
map.put("message", "上传成功");
map.put("filePath", sBuilder.toString());
return map;
}
