bootstrap-fileinput 图片上传

bootstrap-fileinput 源文件 在网上下载CSS:<link href="../../static/Bootstrap/css/plugins/bootstrap-fileinput/fileinput.min.css" rel="stylesheet" />JS:<script src="../../static/Bootstrap/js/plugins/bootstrap-fileinput/fileinput.min.js"></script>
<script src="../../static/Bootstrap/js/plugins/bootstrap-fileinput/fileinput_locale_zh.js"></script>HTML代码：

<form enctype="multipart/form-data">
<div class="row" style="height: 500px">
<input id="file-1" type="file" multiple class="file" data-overwrite-initial="false" data-min-file-count="1">
</div>
</form>

//上传
$("#file-1").fileinput({
uploadUrl: '/Handler/upload.ashx', // 图片上传URL
allowedFileExtensions: ['jpg', 'png', 'gif'],
overwriteInitial: false,
maxFileSize: 1000,
maxFilesNum: 10,
allowedFileTypes: ['image', 'video', 'flash'],
slugCallback: function (filename) {
return filename.replace('(', '_').replace(']', '_');
}
});

//回调函数 当上次成功之后 返回
$("#file-1").on("fileuploaded", function(event, data, previewId, index) {

alert(data.response.JsMessage)

})

upload.ashx 一般处理程序，返回json 格式：

context.Response.Write(JsonConvert.SerializeObject(new { success = true, JsCode = 1, JsMessage = "返回的信息" }));
