1、首先導入要用的js庫
2、在xml配置
3.jsp頁面
<button id="impExcelBtn" type="button" class="btn btn-primary">
<span class="fa fa-file-excel-o fa-fw"></span>導入</button>
上傳文件框
<div class="modal fade" id="ImpModal" tabindex="-1" role="dialog" aria-hidden="true" data-backdrop='static'>
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"
aria-hidden="true">×</button>
<h4 class="modal-title" id="impFile">導入Excel名單</h4>
</div>
<div class="modal-body">
<form class="impExcelPath form-horizontal">
<div class="form-group">
<label class="col-xs-2 control-label">文件路徑</label>
<div class="col-sm-9">
<input type="file" id="excelfile" name="file" />
</div>
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default btn-sm"
data-dismiss="modal">
<i class="fa fa-close fa-fw"></i>  關閉
</button>
</div>
</div>
</div>
</div>
js中代碼
$('#excelfile').fileinput({
uploadUrl: 'flowUpload.do?tradeCode=200403&formCode=QZ100103',
msgPlaceholder: '請選擇一個文件...',
enctype: 'multipart/form-data',
uploadAsync: false,
showCancel: false,
showUpload: true,
showRemove: false,
showCaption: true,
showPreview: false,
dropZoneEnabled: false,
autoReplace: true,
maxFileCount: 1,
validateInitialCount: true,
allowedFileExtensions: ['xlsx', 'xls'],
language: 'zh'
}).on('filebatchuploadsuccess', function(event, data, previewId, index) {
$('#ImpModal').modal('hide');
$(event.target).fileinput('clear').fileinput('unlock');
alertMsg(data.response.msg);
}).on('filebatchuploaderror', function(event, data, previewId, index) {
$('#ImpModal').modal('hide');
$("#excelfile").fileinput('clear').fileinput('unlock');
alertMsg(data.response.msg);
});
$('#impExcelBtn').on('click', function() {
$(".fileinput-remove-button").click();
$('#ImpModal .modal-title').html('導入Excel名單');
$("#excelfile").fileinput('clear').fileinput('unlock');
$('#ImpModal').modal();
});
