Question

我的html代码如下所示

using System;
using System.Diagnostics;
using System.Runtime.InteropServices;

namespace SplitIntIntoBytes
{
    [StructLayout(LayoutKind.Explicit)]
    struct FooUnion
    {
        [FieldOffset(0)]
        public byte byte0;
        [FieldOffset(1)]
        public byte byte1;
        [FieldOffset(2)]
        public byte byte2;
        [FieldOffset(3)]
        public byte byte3;

        [FieldOffset(0)]
        public int integer;
    }
    class Program
    {
        static void Main(string[] args)
        {
            testUnion();
            testBitConverter();

            Stopwatch Timer = new Stopwatch();

            Timer.Start();
            int sumTestUnion = testUnion();
            Timer.Stop();

            Console.WriteLine("time of Union:        " + Timer.ElapsedTicks + " milliseconds,  sum: " + sumTestUnion);

            Timer.Restart();
            int sumBitConverter = testBitConverter();
            Timer.Stop();

            Console.WriteLine("time of BitConverter: " + Timer.ElapsedTicks + " milliseconds,  sum: " + sumBitConverter);
            Console.ReadKey();
        }

        static int testBitConverter()
        {
            byte[] UnionBytes = new byte[4];
            byte[] SumOfBytes = new byte[4];
            SumOfBytes[0] = SumOfBytes[1] = SumOfBytes[2] = SumOfBytes[3] = 0;

            for (int i = 0; i < 10000; i++)
            {
                UnionBytes = BitConverter.GetBytes(i);
                SumOfBytes[0] += UnionBytes[0];
                SumOfBytes[1] += UnionBytes[1];
                SumOfBytes[2] += UnionBytes[2];
                SumOfBytes[3] += UnionBytes[3];
            }
            return SumOfBytes[0] + SumOfBytes[1] + SumOfBytes[2] + SumOfBytes[3];
        }

        static int testUnion()
        {
            byte[] UnionBytes;
            byte[] SumOfBytes = new byte[4];
            SumOfBytes[0] = SumOfBytes[1] = SumOfBytes[2] = SumOfBytes[3] = 0;

            FooUnion union = new FooUnion();

            for (int i = 0; i < 10000; i++)
            {
                union.integer = i;
                UnionBytes = new byte[] { union.byte0, union.byte1, union.byte2, union.byte3 };
                SumOfBytes[0] += UnionBytes[0];
                SumOfBytes[1] += UnionBytes[1];
                SumOfBytes[2] += UnionBytes[2];
                SumOfBytes[3] += UnionBytes[3];
            }
            return SumOfBytes[0] + SumOfBytes[1] + SumOfBytes[2] + SumOfBytes[3];
        }
    }
}

我想获取name =“”里面的内容，其中是loginSGizS，现在我看到明显的方法是通过输入id，但是我不太清楚

更新：我在带有curl的php文件中使用此文件，我有点需要将所有内容保留在该文件中。到目前为止我尝试过的

val ans = Mono.fromCallable { null }.block() 
Assert.assertEquals(null, ans)

更新：我使用了正则表达式<input type="text" class="bk-i bk-fill-parent" id="loginField" name="loginSGizS" autocomplete="off" maxlength="20">，它可以正常工作，谢谢大家：）

Answer 1

document.getElementById("loginField").getAttribute("name")

Answer 2

您可以通过attr方法轻松获得它：

var name = $("#id").attr("name");

DOM通过输入ID获取名称元素
