一、引入文件
<link href="../css/bootstrap.min.css"rel="stylesheet">
<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
//初始化fileinput
initFileInput();
function initFileInput() {
$("#uploadImg").fileinput({
language: 'zh', //设置语言
dropZoneTitle: '可以将图片拖放到这里 …支持多文件上传',
uploadUrl: "index.php", //上传的地址
uploadExtraData: function(previewId, index) { //该插件可以向您的服务器方法发送附加数据。这可以通过uploadExtraData在键值对中设置为关联数组对象来完成。所以如果你有设置uploadExtraData={id:'kv-1'},在PHP中你可以读取这些数据$_POST['id']
var id = $('#id').val();
return {seriesId: id};
},
allowedFileExtensions: ['jpg','png'],//接收的文件后缀
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
showCancel:true, //是否显示文件上传取消按钮。默认为true。只有在AJAX上传过程中,才会启用和显示
showCaption: true,//是否显示文件标题,默认为true
browseClass: "btn btn-primary", //文件选择器/浏览按钮的CSS类。默认为btn btn-primary
dropZoneEnabled: true,//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: 1024,//单位为kb,如果为0表示不限制文件大小
minFileCount: 1, //每次上传允许的最少文件数。如果设置为0,则表示文件数是可选的。默认为0
maxFileCount: 0, //每次上传允许的最大文件数。如果设置为0,则表示允许的文件数是无限制的。默认为0
previewFileIcon: "<i class='glyphicon glyphicon-king'></i>",//当检测到用于预览的不可读文件类型时,将在每个预览文件缩略图中显示的图标。默认为<i class="glyphicon glyphicon-file"></i>
layoutTemplates:{
actionUpload:''//去除上传预览缩略图中的上传图片
actionZoom:'', //去除上传预览缩略图中的查看详情预览的缩略图标
actionDownload:'' //去除上传预览缩略图中的下载图标
actionDelete:'', //去除上传预览的缩略图中的删除图标
},//对象用于渲染布局的每个部分的模板配置。您可以设置以下模板来控制窗口小部件布局.eg:去除上传图标
msgFilesTooMany: "选择上传的文件数量({n}) 超过允许的最大数值{m}!",//字符串,当文件数超过设置的最大计数时显示的消息 maxFileCount。默认为:选择上传的文件数({n})超出了允许的最大限制{m}。请重试您的上传!
}).on('filebatchpreupload', function(event, data) { //该方法将在上传之前触发
var id = $('#id option:selected').val();
if(id == 0){
return {
message: "请选择", // 验证错误信息在上传前要显示。如果设置了这个设置,插件会在调用时自动中止上传,并将其显示为错误消息。您可以使用此属性来读取文件并执行自己的自定义验证
data:{} // any other data to send that can be referred in `filecustomerror`
};
}
});
}
//fileuploaded此事件仅针对ajax上传触发,并在每个缩略图文件上传完成后触发。此事件仅针对ajax上传并在以下情况下触发:当点击每个预览缩略图中的上传图标并且文件上传成功时,或者当你有 uploadAsync设置为true您已触发批量上传。在这种情况下,fileuploaded每一个人选择的文件被上传成功后,触发事件。
var id_str = '';
$('#uploadImg').on('fileuploaded', function(event, data, previewId, index) {
if(typeof(data.response.id) != 'undefined'){
id_str = id_str+data.response.id+',';
}
});
// filebatchuploadcomplete此事件仅在ajax上传和完成同步或异步ajax批量上传后触发。
$('#uploadImg').on('filebatchuploadcomplete',function (event,files,extra) {
if(id_str.length == 0){
layer.msg('上传失败', {icon: 0});//弹框提示
return false;
}
setTimeout(function(){ //执行延时关闭
closeSelf();
},1000);
});
