Question

下面的代码对我来说很好，但是我还想每3秒重新加载一次feed_back DIV我该怎么办呢帮忙

Post.js

$('#btn').click(function(){
    var msg = $("#msg").val();
    $.post('realtimemsg.php',{ input:msg },function(data){
        $('#feed_back').html(data);

    });
});

的index.php

   <div id="feed_back"></div>
    </body>
</html>

<script type ="text/javascript" src="post.js"></script>
<script type="text/javascript">
        $(document).ready(function() {

            setInterval(function () {
                $('#feed_back').load('#feed_back')
        }, 3000);
    });

这是我到目前为止所拥有的

你可以这样做。

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {

            var file1 = @"C:\Program Files (x86)\Electronic Arts\Crysis 3\Bin32\Crysis3.exe"; // 26MB
            var file2 = @"C:\Program Files (x86)\Electronic Arts\Crysis 3\Bin32\d3dcompiler_46.dll"; // 3MB
            List<string> files = new List<string> { file1, file2 };

            var sw = System.Diagnostics.Stopwatch.StartNew();

            // Prepare array of counters for the bytes
            var nFiles = files.Count;
            int[][] count = new int[nFiles][];
            for (int i = 0; i < nFiles; i++)
            {
                count[i] = new int[256];
            }

            // Get the counts of bytes in each file
            int bufLen = 32768;
            byte[] buffer = new byte[bufLen];

            int bytesRead;

            for (int fileNum = 0; fileNum < nFiles; fileNum++)
            {
                using (var sr = new FileStream(files[fileNum], FileMode.Open, FileAccess.Read))
                {
                    bytesRead = bufLen;
                    while (bytesRead > 0)
                    {
                        bytesRead = sr.Read(buffer, 0, bufLen);
                        for (int i = 0; i < bytesRead; i++)
                        {
                            count[fileNum][buffer[i]]++;
                        }
                    }
                }
            }

            // Find which bytes are in any of the files or in all the files
            var inAny = new List<byte>(); // union
            var inAll = new List<byte>(); // intersect

            for (int i = 0; i < 256; i++)
            {
                Boolean all = true;
                for (int fileNum = 0; fileNum < nFiles; fileNum++)
                {
                    if (count[fileNum][i] > 0)
                    {
                        if (!inAny.Contains((byte)i)) // avoid adding same value more than once
                        {
                            inAny.Add((byte)i);
                        }
                    }
                    else
                    {
                        all = false;
                    }
                };

                if (all)
                {
                    inAll.Add((byte)i);
                };

            }

            sw.Stop();

            Console.WriteLine(sw.ElapsedMilliseconds);

            // Display the results
            Console.WriteLine("Union: " + string.Join(",", inAny.Select(x => x.ToString("X2"))));
            Console.WriteLine();
            Console.WriteLine("Intersect: " + string.Join(",", inAll.Select(x => x.ToString("X2"))));
            Console.WriteLine();

            // Compare to using LINQ.
            // N/B. Will need adjustments for more than two files.

            var srcBytes1 = File.ReadAllBytes(file1);
            var srcBytes2 = File.ReadAllBytes(file2);

            sw.Restart();

            var intersect = srcBytes1.Intersect(srcBytes2).ToArray().OrderBy(x => x);
            var union = srcBytes1.Union(srcBytes2).ToArray().OrderBy(x => x);

            Console.WriteLine(sw.ElapsedMilliseconds);

            Console.WriteLine("Union: " + String.Join(",", union.Select(x => x.ToString("X2"))));
            Console.WriteLine();
            Console.WriteLine("Intersect: " + String.Join(",", intersect.Select(x => x.ToString("X2"))));

            Console.ReadLine();

        }
    }
}

而且，你不需要这个部分：

var _timer = null;
$('#btn').click(function() {
    clearInterval(_timer);        
    _timer = setInterval(function() {
        var msg = $("#msg").val();
        $.post('realtimemsg.php', {
            input: msg
        }, function(data) {
            $('#feed_back').html(data);

        });
    }, 3000);
})

重新加载div并将数据发布到同一个div
