大家好，又见面了，我是你们的朋友全栈君。
一、 引入文件

<link href=”../css/fileinput.css” media=”all”rel=”stylesheet” type=”text/css” />
<scriptsrc=”../js/jQuery-2.0.3.min.js”></script>
<script src=”../js/fileinput.js”type=”text/JavaScript“></script>
<script src=”../js/bootstrap.min.js”type=”text/javascript“></script>
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: “<iclass=’glyphicon glyphicon-king’></i>”,
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){
});

六、 常见错误：
(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
