如何选择 id 包含给定字符串的 html 元素？querySelectorAll 会完成这个吗？我知道我可以使用 querySelectorAll 选择类、ID、属性等，

只是不确定我需要做什么的正确方法

这是一些代码，我只想获取 id 包含 Home 的元素

<div id="ContactContainer>
    <input class="form-control input-sm clear" is-required="false" validate-number="" minlength="1" maxlength="3" id="txtCustomerWorkAreaCode" placeholder="9999">
    <input class="form-control input-sm clear" is-required="false" validate-number="" minlength="1" maxlength="3" id="txtCustomerWorkExchange" placeholder="9999">
    <input class="form-control input-sm clear" is-required="false" validate-number="" minlength="4" maxlength="4" id="txtCustomerWorkSuffix" placeholder="9999">


    <input class="form-control input-sm clear" is-required="false" validate-number="" minlength="1" maxlength="3" id="txtCustomerHomeAreaCode" placeholder="9999">
    <input class="form-control input-sm clear" is-required="false" validate-number="" minlength="1" maxlength="3" id="txtCustomerHomeExchange" placeholder="9999">
    <input class="form-control input-sm clear" is-required="false" validate-number="" minlength="4" maxlength="4" id="txtCustomerHomeSuffix" placeholder="9999">


    <input class="form-control input-sm clear" …

我有我写的这个存储过程,当我去执行它时,我一直收到错误...

消息102,级别15,状态1,过程s_Add $ Subject $ Info,第127行
'@V'附近的语法不正确.

当我去第127行并环顾四周时,我看不到该行甚至是该区域的语法错误.有没有我没看到的东西？这是存储过程:

CREATE PROCEDURE s_Add$Subject$Info
(
   @SubjectName varchar(50),
   @SubjectDescription varchar(max),
   @QuizIDString varchar(100),
   @GamesIDString varchar(100),
   @VideoIDString varchar(100)
)
as
--declare variables
declare @theSubID int
declare @quizIDLength int
declare @gamesIDLength int
declare @videoIDLength int
declare @quizIDs varchar(200)
declare @gamesIDs varchar(200)
declare @videoIDs varchar(200)
declare @numberCount int
declare @sTemp varchar(100)

--initializing variables
set @quizIDLength = LEN(@QuizIDString)
set @gamesIDLength = LEN(@GamesIDString)
set @videoIDLength = LEN(@VideoIDString)
set @quizIDs = ''
set @gamesIDs = ''
set @videoIDs = ''
set …

我试图弄清楚如何使用VerifyHashedPassword方法,这是我到目前为止所得到的.我怎么知道密码是否已经过验证？

public bool VerifyPassword(string pass)
    {
        PasswordHasher passwordHasher = new PasswordHasher();

        HDA = new HWCDA();

        HWCE = new HWCEntities();

        string userPass = HWCE.AspNetUsers.Where(w => w.UserID == 1).Select(s => s.PasswordHash).FirstOrDefault().ToString();

        bool result = false;

        passwordHasher.VerifyHashedPassword(userPass, pass);

        return false;            
    }

我有一个if语句

if (materialtype != "WINDOWVINYLREPL"
    || materialtype != "ROOFING"
    && materialtype != "null"
    && materialtype != null)
{                
    subtype = (from a in UEF.MaterialSubTypes 
               where a.MaterialSubType1.Equals(subtype) && a.Code.Contains(materialtype) 
               select a.Code).FirstOrDefault();
}

即使materialtype等于null,if语句仍然被调用,它不应该被调用

我正在使用for循环遍历一个包含链接的列表,我正在尝试获取href的值而不是成功.我可以通过这样做返回链接..

让我= $('#wizTabs li a');

但仍无法获得href.

我试过我[i] .attr("href"),我得到一个关于attr不是函数的错误.我也尝试过$(这个)但是没有用

let me = $('#wizTabs li');

for (i = 0; i < me.length; i++) {
  console.log(me[i]);
}
