问题描述

朋友们，



现在我的编码就像这样。

hi friends,

Now I''m coding like this.

<script type="text/javascript" language="javascript">
    $(function () {
        var checkOut = 'invalid';
        var lblOldPwd = $('#<%= lblOldPwd.ClientID %>');
        var lblNewPwd = $('#<%= lblNewPwd.ClientID %>');
        var lblConfPwd = $('#<%= lblConfPwd.ClientID %>');
        $('#<%= txtOldPwd.ClientID %>').blur(function () {
            oldPassword();
        });
        $('#<%= txtNewPwd.ClientID %>').blur(function () {
            newPassword();
        });
        $('#<%= txtConfirmPwd.ClientID %>').blur(function () {
            confirmPassword();
        });
        $('#<%= btnSubmit.ClientID %>').click(function () {
            oldPassword();
            if (checkOut == 'invalid') {
                return false;
            }
            newPassword();
            if (checkOut == 'invalid') {
                return false;
            }
            confirmPassword();
            if (checkOut == 'invalid') {
                return false;
            }
        });
        function oldPassword() {
            if ($('#<%= txtOldPwd.ClientID %>').val() == "") {
                lblOldPwd.html('Please Enter Old Password.<BR>');
                $('#<%= txtOldPwd.ClientID %>').css('border', '1px solid red');
                $('#<%= txtOldPwd.ClientID %>').focus();
                checkOut = 'invalid';
                return false;
            }
            else if ($('#<%= txtOldPwd.ClientID %>').val() != "") {
                $('#<%= txtOldPwd.ClientID %>').css('border', '1px solid #a4c9e3');
                checkOut = 'valid';
                lblOldPwd.html('');
            }
        }
        function newPassword() {
            if ($('#<%= txtNewPwd.ClientID %>').val() == "") {
                lblNewPwd.html('Please Enter New Password.<BR>');
                $('#<%= txtNewPwd.ClientID %>').css('border', '1px solid red');
                $('#<%= txtNewPwd.ClientID %>').focus();
                checkOut = 'invalid';
                return false;
            }
            else if ($('#<%= txtNewPwd.ClientID %>').val() != "") {
                $('#<%= txtNewPwd.ClientID %>').css('border', '1px solid #a4c9e3');
                checkOut = 'valid';
                lblNewPwd.html('');
            }
        }
        function confirmPassword() {
            if ($('#<%= txtConfirmPwd.ClientID %>').val() == "") {
                lblConfPwd.html('Please Enter confirm password to proceed.');
                $('#<%= txtConfirmPwd.ClientID %>').css('border', '1px solid red');
                $('#<%= txtConfirmPwd.ClientID %>').focus();
                checkOut = 'invalid';
                return false;
            }
            else if ($('#<%= txtConfirmPwd.ClientID %>').val().length > 1) {
                $('#<%= txtConfirmPwd.ClientID %>').css('border', '1px solid #a4c9e3');
                checkOut = 'valid';
                lblConfPwd.html('');
            }
        }
    });
</script>

这里我在diffirent功能方面做同样的工作。我想创建一个函数，比如



funcation funcationName（txtboxid，labelID）

{

/// /

}



这样我就可以在功能中传递文本框和标签并使用相同的功能。根据我的要求，而不是一次又一次地使用相同的代码。





如何创建单一功能来执行此操作。



请帮助我。

here I''m doing same same work in diffirent funcation. I want to create a funcation like

funcation funcationName(txtboxid, labelID)
{
////
}

so that i can pass textbox and label in function and use this same function. as per my requirement rather then using same code again and again.


how can i create single function to do this.

pls help me.

推荐答案

（function（）{
var checkOut ='invalid';
var lblOldPwd =

(function () { var checkOut = 'invalid'; var lblOldPwd =

（'＃<％ = lblOldPwd.ClientID ％> '）;
var lblNewPwd =

('#<%= lblOldPwd.ClientID %>'); var lblNewPwd =

（'＃<％ = lblNewPwd.ClientID ％> '）;
var lblConfPwd =

('#<%= lblNewPwd.ClientID %>'); var lblConfPwd =
