POI导出数据并且实现导出时显示进度条
js代码
/* 进度条隐藏 */
function modalClose() {
//$("#myModal").modal('hide');
$('#PerExcelModal').modal('hide');
$(".modal-backdrop").remove();
$("body").removeClass('modal-open');
//$("#d").trigger('click');
}
function ajax_send(func){
$.ajax({
type:"POST",
url: "${base}/business/order/isExport",
datatype:"json",
success:function(res){
var res=JSON.parse(res);
func.call(this,res);
}
});
}
function aa(){
var interval = setInterval(function(){
ajax_send(function(res){
if(res){
modalClose();
clearInterval(interval);
}else{
};
});
},1000); //每隔1秒调用一次函数
};
//导出excel
$repExcel.click(function(){
var status=$("#status").val();
$("#prestatus").val(status);
var type=$("#type").val();
$("#pretype").val(type);
/* var searchValue=$("#searchValue").val();
$("#presearchValue").val(searchValue); */
$("#repFrom").submit();
//setTimeout(modalClose, 5000);
aa();
});
