rt，代碼如下：

login()?{

cancel()?{

},
confirm()?{
??if(this.pwd?===?this.pwda?&&?this.name?!==?''?&&?this.pwd?!==?'')?{

??}
}

沒有報(bào)錯(cuò)，問題在于點(diǎn)擊任意按鈕時(shí)頁面都會(huì)自動(dòng)刷新，這就導(dǎo)致點(diǎn)擊注冊(cè)時(shí)，注冊(cè)表單一閃而過刷新回登錄，此時(shí)url為localhost:8080/?，我重啟服務(wù)、瀏覽器都沒有用。

還有最后這個(gè)confirm函數(shù)，空信息注冊(cè)會(huì)彈窗，但是localstorage也會(huì)存數(shù)據(jù)，相當(dāng)于兩個(gè)分支都走了一遍，有點(diǎn)不可思議，是我判斷的條件有問題嗎？

有點(diǎn)懵，還請(qǐng)賜教。
