<link href="../../css/fileinput.min.css" rel="stylesheet">

然后是html代碼因?yàn)槲也皇菍I(yè)前端所以前端代碼寫的很爛輕噴敲打

<!-- 模態(tài)框（Modal） --> 
<span style="white-space:pre"> </span><div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">

<span style="white-space:pre"> </span></div><!-- /.modal-content --> 
<span style="white-space:pre"> </span></div><!-- /.modal --> 
<span style="white-space:pre"> </span></div>

然后是js代碼初始化file-input

//初始化fileinput控件（第一次初始化） 
function initFileInput(ctrlName, uploadUrl) { 
var control = $('#' + ctrlName); 
control.fileinput({ 
language: 'zh', //設(shè)置語言 
uploadUrl: uploadUrl, //上傳的地址 
allowedFileExtensions : ['jpg', 'png','gif'],//接收的文件后綴 
showUpload: true, //是否顯示上傳按鈕 
showCaption: false,//是否顯示標(biāo)題 
browseClass: "btn btn-primary", //按鈕樣式 
previewFileIcon: "<i class='glyphicon glyphicon-king'></i>", 
uploadAsync: false, 
uploadExtraData:function (previewId, index) { 
var obj = {}; 
$('#addForm').find('input').each(function() { 
var id = $(this).attr('id'), val = $(this).val(); 
obj[id] = val; 
}); 
return obj; 
} 
}); 
} 
//初始化fileinput 
initFileInput("fileup", http://localhost:8080/web/guita/addGuitaInfo.action);

這段代碼是插件的核心了

upLoadUrl是后臺給的訪問路徑了

這里特別要注意的是這一段

uploadExtraData:function (previewId, index) { 
var obj = {}; 
$('#addForm').find('input').each(function() { 
var id = $(this).attr('id'), val = $(this).val(); 
obj[id] = val; 
}); 
return obj; 
}

這一段代碼uploadExtraData適用于傳額外參數(shù)是可以用于提交form表單的其他input框數(shù)據(jù)

uploadExtraData:{ 
type:"type", 
tune:"tune" 
}

一般的靜態(tài)數(shù)據(jù)如上圖提交后臺就可以直接接到了但是這樣寫會得不到動態(tài)數(shù)據(jù) 數(shù)據(jù)只會在初始化的時(shí)候生成一次之后不會改變
這個(gè)問題糾結(jié)了我不少時(shí)間最后是在git上面看外國朋友們的討論然后參考api才解決掉
