大家好，又见面了，我是你们的朋友全栈君。
官网下载文件http://plugins.krajee.com/file-input/demo
bootstrap fileinput 是基于bootstrap基础上的上传插件，so必要的bootstrap文件是要引用的…
1.引用js和css文件
fileinput.css
fileinput.min.js
中文字体
2.初始化fileinput
前台
jsp：
代码语言：javascript复制<input id="debugId" name="debugId" hidden="true" /> <!-- 文件上传额外参数 -->
<input id="fileInput" name="files" multiple type="file" class="file" value=""/>如果已经存在，换个名字即可，如class=”file1″class
js：
代码语言：javascript复制step1：上传部分，可携带额外参数
$("#fileInput").fileinput('destroy'); // 直接销毁
$("#fileInput").fileinput({
language: 'zh', //设置语言
uploadUrl: GLOBAL.URL 'project/saveFile.do', //上传的地址 http;//localhost:8080/project/saveFile.do
showUpload: false, //是否显示上传按钮
showCaption: false,//是否显示标题
previewFileIcon: "<i class='glyphicon glyphicon-king'></i>",
maxFileCount: 6, //表示允许同时上传的最大文件个数
fileActionSettings:{showUpload: false}, // 控制上传按钮是否显示
uploadExtraData: function(previewId, index) { //额外参数
var obj = {};
obj.id = fodderType(); // 这里回调方法
return obj;
},
preferIconicPreview: true, // 开启用图标替换预览效果
previewFileIconSettings: { // configure your icon file extensions
'doc': '<i class="fa fa-file-word-o text-primary"></i>',
'xls': '<i class="fa fa-file-excel-o text-success"></i>',
'ppt': '<i class="fa fa-file-powerpoint-o text-danger"></i>',
'pdf': '<i class="fa fa-file-pdf-o text-danger"></i>',
'txt': '<i class="fa fa-file-text-o text-info"></i>',
'zip': '<i class="fa fa-file-archive-o text-muted"></i>',
'htm': '<i class="fa fa-file-code-o text-info"></i>',
'mov': '<i class="fa fa-file-movie-o text-warning"></i>',
'mp3': '<i class="fa fa-file-audio-o text-warning"></i>'
},
previewFileExtSettings: {
'doc': function(ext) {
return ext.match(/(doc|docx)$/i);
},
'xls': function(ext) {
return ext.match(/(xls|xlsx)$/i);
},
'ppt': function(ext) {
return ext.match(/(ppt|pptx)$/i);
},
'zip': function(ext) {
return ext.match(/(zip|rar|tar|gzip|gz|7z)$/i);
},
'htm': function(ext) {
return ext.match(/(htm|html)$/i);
},
'mov': function(ext) {
return ext.match(/(avi|mpg|mkv|mov|mp4|3gp|webm|wmv)$/i);
},
'mp3': function(ext) {
return ext.match(/(mp3|wav)$/i);
},
'txt': function(ext) {
return ext.match(/(txt|ini|csv|java|php|js|css)$/i);
}
},
layoutTemplates:{ // 预览图片按钮控制，这里屏蔽预览按钮
actionZoom:''
}
});
fodderType = function() {
return $("#debugId").val();
};
step2：单独调用上传
$("#fileInput").fileinput("upload");
step3：控件回显重新初始化
// 假设后台信息已经查询完毕！假设为data！！
$("#fileInput").fileinput('destroy');
$("#fileInput").fileinput({
language: 'zh', //设置语言
uploadUrl: GLOBAL.URL 'project/saveFile.do?id=' bugId, //上传的地址
showUpload: false, //是否显示上传按钮
showCaption: false,//是否显示标题
maxFileCount: 6, //表示允许同时上传的最大文件个数
fileActionSettings:{showUpload: false},//是否显示上文件上的上传按钮
overwriteInitial: false,
allowedPreviewTypes: ['image'],
/*

initialPreview: [
