第二次函数调用后，提交按钮停止工作

/ * edit * /更改了提交编辑和提交转移按钮的ID，因为ID是重复的。

我正在编写一个脚本，该脚本从MySQL数据中提取表格，并使用户能够编辑/删除/传输所述数据。在初始页面加载时，一切正常。但是，当我选择一个新表时，传输和编辑按钮将停止运行。即使我选择传出表（最初加载的表）也是如此。所以，问题出现在页面重新加载后的某个地方，我只是不知道在哪里。传输和编辑按钮旁边的每个按钮都可以工作。

这是脚本的屏幕上限，这样您就可以了解我正在尝试做什么。

enter image description here

这是我的代码：

<?php
require("IRCinventoryfunctions.php");
require_once 'IRCinventoryconfig.php';

$aTable = file_get_contents('php://input');
$aTable = substr($aTable, 6);

$connection = new mysqli($db_hostname, $db_username, $db_password, $db_database, $db_port);
    if ($connection->connect_error) die($connection->connect_error);
    global $connection;

$result = $connection->query("SHOW TABLES");

$table = array();
    while ($row = $result->fetch_row()){
    $table[] = $row[0];
    }
$count = count($table);
?>

<div id="content">

<?php
$thatTable = !empty($aTable) ? $aTable : "OUTGOING";
    {
session_start();
$_SESSION['thatTable'] = $thatTable;
global $thatTable;  

$queryColumns  = "SHOW COLUMNS FROM $thatTable";
$resultColumns = $connection->query($queryColumns);
    if (!$resultColumns) die ("Database access failed: " . $connection->error);
global $resultColumns;

$queryRows  = "SELECT * FROM $thatTable";
    $resultRows = $connection->query($queryRows);
    if (!$resultRows) die ("Database access failed: " . $connection->error);
global $resultRows;

$rows = $resultRows->num_rows;
global $rows;

global $connection;

drawTable();

$connection->close();
} 
?>

这是绘图表功能：

function drawTable() {

global $connection;
global $resultColumns;
global $resultRows;
global $rows;
global $columns;
global $countColumnsGlobal;
global $thatTable;

$columns = array();
    while ($column = $resultColumns->fetch_row()){
        $columns[] = $column[0];
     }

echo "<div id=\"table\"><table class=\"CSSTableGenerator\" >\n";

$countColumns = count($columns);
$countColumnsGlobal = $countColumns;

$insertColumns = array();
for ($pointer = 1 ; $pointer < $countColumns ; ++$pointer) {
    $insertColumns[] = $columns[$pointer];
    }

for ($pointer = 1 ; $pointer < $countColumns ; ++$pointer) {
    echo "<th scope=\"col\" bgcolor=\"#efefef\">";
    echo $columns[$pointer];
    echo "</th>";
    }
    echo "<th>ACTIONS</td>";

for ($j = 0 ; $j < $rows ; ++$j)
    {
        $resultRows->data_seek($j);
        $row = $resultRows->fetch_array(MYSQLI_NUM);

        $countRows = count($row);

        echo "<tr>";
        for ($pointer = 1 ; $pointer < $countRows ; ++$pointer) {
            echo "<td>";
            echo $row[$pointer];
            echo "</td>";
        }

        global $I_ID;
            echo "<td>";
                echo "<form name=\"deleteRow\" action=\"http://localhost:8888/IRC/IRCprocessinventory.php\" method=\"POST\">";

                echo "<div id=\"transfer\"><input type=\"button\" name=\"$I_ID\" value=\"transfer\"></div>";
            echo "</td>";
        echo "</tr>";

        echo "<tr id=\"$I_ID\" class=\"edit\">";
        echo "<form name=\"editRow\" action=\"IRCprocessinventory.php\" method=\"POST\">";
            echo "<input type=\"hidden\" name=\"edit\">";
            echo "<input type=\"hidden\" name=\"$thatTable\">";
            echo "<input type=\"hidden\" value=\"$I_ID\" name=\"I_ID\">";
            echo "<input type=\"hidden\" value=\"$row[1]\" name=\"$columns[1]\">";
            echo "<td>$row[1]</td>";
            for ($pointer = 2 ; $pointer < $countRows ; ++$pointer) {
                echo "<td>";
                echo "<input type=\"text\" value=\"$row[$pointer]\" name=\"$columns[$pointer]\">";
                echo "</td>";
            }
            echo "<td><input type=\"submit\" id=\"submitEdit\" class=\"submitEdit\" name=\"$I_ID\" value=\"submit edit\"></td>";
        echo "</form>";
        echo "</tr>";

        echo "<tr id=\"transfer\" class=\"$I_ID\">";
        echo "<form name=\"transfer\" action=\"IRCprocessinventory.php\" method=\"POST\">";
            echo "<input type=\"hidden\" name=\"transfer\">";
            echo "<input type=\"hidden\" name=\"$thatTable\">";
            echo "<input type=\"hidden\" value=\"$I_ID\" name=\"I_ID\">";
            echo "<td>Transfer to OUTGOING</td>";
            echo "<td>$row[2]</td>";
            echo "<td><input type=\"text\" name=\"amountTransferred\"></td>";
            for ($pointer = 5 ; $pointer < $countRows + 1 ; ++$pointer) {
                echo "<td></td>";
            }
            for ($pointer = 0 ; $pointer < $countRows + 1 ; ++$pointer) {
                echo "<input type=\"hidden\" name=\"$row[$pointer]\" value=\"$columns[$pointer]\">";

1 个答案:

答案 0 :(得分：2)

表格在选择时通过AJAX加载，因此新的DOM元素没有附加点击按钮事件处理程序。

完成AJAX调用后，重新绑定事件处理程序以获取按钮。

这应该可以解决问题。

希望它有所帮助！
