做webform注意事項 閏年日期

標籤：注意事項   頁面   erro   修改密碼   htm   ++   ntb   inner   this   

1、展示細節

如男女顯示問題 不能顯示true   false  時間轉換成中文  民族顯示漢字  不能直接顯示代碼
2、使用者名稱重複驗證

從資料庫中查詢驗證
4、日期判斷

判斷年份有點問題

 var year = document.getElementById("Dr_Year");    var mon = document.getElementById("Dr_Month");    var day = document.getElementById("Dr_Day");    document.getElementById("Dr_Year").onchange = function () {                if (mon.value == "2")        {            if (this.value % 4 == 0)            {                day.options.length = 0;                for (var i = 1; i < 30; i++)                {                    var op = document.createElement("option");                    op.value = i;                    op.innerHTML = i;                    day.appendChild(op);                }            }            else {                day.options.length = 0;                for (var i = 1; i < 29; i++) {                    var op = document.createElement("option");                    op.value = i;                    op.innerHTML = i;                    day.appendChild(op);                }            }        }    }    document.getElementById("Dr_Month").onchange = function () {                if (this.value == "2") {            if (year.value % 4 == 0) {                day.options.length = 0;                for (var i = 1; i < 30; i++) {                    var op = document.createElement("option");                    op.value = i;                    op.innerHTML = i;                    day.appendChild(op);                }            }            else {                day.options.length = 0;                for (var i = 1; i < 29; i++) {                    var op = document.createElement("option");                    op.value = i;                    op.innerHTML = i;                    day.appendChild(op);                }            }        }        else if (this.value == "1" || this.value == "3" || this.value == "5" || this.value == "7" || this.value == "8" || this.value == "10" || this.value == "12") {            day.options.length = 0;            for (var i = 1; i < 32; i++) {                var op = document.createElement("option");                op.value = i;                op.innerHTML = i;                day.appendChild(op);            }        } else {            day.options.length = 0;            for (var i = 1; i < 31; i++) {                var op = document.createElement("option");                op.value = i;                op.innerHTML = i;                day.appendChild(op);            }        }    }

 

5、修改頁面無法提交

6、編輯時，如密碼不填，則保留原有密碼

一般都是單獨改密碼    統一改的時候在修改方法裡面加一個判斷 

執行語句 如果密碼為空白則不修改密碼 

密碼不為空白在修改

 

 

用js判斷密碼是否一致

var p1 = document.getElementById("TextBox2");    var p2 = document.getElementById("TextBox3");    p1.onkeyup = function () { pwdisok(p1, p2); }    p2.onkeyup = function () { pwdisok(p1, p2); }    function pwdisok(pwd1, pwd2) {        if (pwd1.value != pwd2.value) {            document.getElementById("pwd_error").innerText = "兩次密碼不一致！";            document.getElementById("pwd_error").style.color = "red";            pwdok = false;        }        else {            document.getElementById("pwd_error").innerText = "正確！";            document.getElementById("pwd_error").style.color = "green";            pwdok = true;        }    }
