这段コード提神-JavaはEXCELテンプレート化導出を実現します.ajax+springMVCまたはStrutsは例です.
いつもあれだけのことがあって、振り返るに忍びないです.
仕事をする時はこの点で基本的にコードを持ってきて元気を出さなければなりません.
第一歩:EXCELテンプレートを用意する
ドル("刋export Btn").click(function(ev){ return$ajax({ url:'/url' type:'post'は、 dataType:'json'は、 data:{ start:$(「璖begiDate」).val() end:$(「璖endDate」).val() }, success:function(d){ if(d.success){ location.href=d.address; } } }); });
