2 つのテーブルを含む MySQL データベースがあります。

私が扱っている主なファイルは、index.php、jquery.js、jfunc.js、および urlmappingDB.php です。

私の主な質問は最初の 3 に関するものです。index.php では、urlmappingDB.php で作成したデータ テーブルのデータを html タグで表示しています。テーブルの下の更新ボタンをクリックすると、更新された MySQL テーブル データが html テーブルの対応する位置に表示されます。_POST 配列に渡される変数は、私のプログラムではほぼ任意の変数であるため、現在の jquery コードではテーブルを更新するのに十分ではないと感じています。

そうは言っても、私の雇用主はこれにjqueryを使用することを好むので、これを実装する方法にちょっと困惑しています。これについてどうすればいいですか？

index.php

<?php 
    $con = mysql_connect("localhost", "root", "");

    if (!$con) {
        die("Error: ".mysql_error());
    }

    mysql_select_db("genius", $con);

     $result = mysql_query("SELECT * FROM `urlMappingConsumption`");
?>

もう一方の MySQL テーブルは、次の 2 つのファイルによって定義されます。

CreateUrlMapping.txt

DROP TABLE IF EXISTS `urlMapping`;
SET @saved_cs_client        = @@character_set_client;
SET character_set_client = utf8;
CREATE TABLE `urlMapping` (
    `urlMappingID` bigint(20) unsigned NOT NULL auto_increment,
    `customerID` int(11) default '0',
    `activityID` int(11) default '0',
    `contactID` int(11) default '0',
    `fullURL` mediumtext,
    `lastModified` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
    `developerSandbox` varchar(25) default '',
    PRIMARY KEY (`urlMappingID`),
    KEY `customerActivityID` (`customerID`,`activityID`)
)ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;
SET character_set_client = @saved_cs_client;

と

urlMapping.csv

INSERT INTO urlMapping (urlMappingID,customerID,activityID,contactID,fullURL,lastModified,developerSandbox)
VALUES

これについては、ajax を使用しますが、php ファイルで生データを取得する代わりに onclick を使用して、データをテーブルに入れ、メイン ページに送信します。

$.ajax({
        url: "table.php", 
        type: "GET",
        data: data,     
        cache: false,
        success: function (html) {
            alert("HTLM = " + html);
            $('#table').html(html);
            }
 });

#tableあなたのテーブルが配置されるdivです

htmlajaxがphpファイルからフェッチするもの=テーブル

htmlを#tablediv内に配置します

それでもヘルプが必要な場合はコメントしてください
