我正在使用 PHP 将由 MySQL 查询生成的表注入到混合的 HTML/PHP 文件中，使用<div>. <div>声明index.php如下：<div id="searchdiv"></div>.

的内容<div>是这样生成的：

(1) 创建搜索框：

<form id="searchform">
<td class="master">Codigo o nombre cliente: <input type="text" name="box" onkeypress="return noenter()" /><input id="srchsubmit" type="submit" value="Buscar" onclick="showUser(this.form['box'].value);return false;" /><br /></td></form>

(2) 执行JavaScript：

function showUser(str){
    if (str==""){
        document.getElementById("searchdiv").innerHTML="";
        return;
        }
        if (window.XMLHttpRequest){
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp=new XMLHttpRequest();
            }
            else
            {
                // code for IE6, IE5
                xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
                }
                xmlhttp.onreadystatechange=function(){
                    if (xmlhttp.readyState==4 && xmlhttp.status==200){
                        document.getElementById("searchdiv").innerHTML=xmlhttp.responseText;
                        }
                        }
                        xmlhttp.open("GET","search.php?q="+str,true);
                        xmlhttp.send();
                        }

(3) 构造结果注入<div>：

<?php

// Fetch the string from the search box

$q=$_GET["q"];

// Connection settings

$dbhost = "localhost";
$dbuser = "root";
$dbpass = "";
$dbname = "scorecard";

//Connect to MySQL Server

mysql_connect($dbhost, $dbuser, $dbpass);

//Select Database

mysql_select_db($dbname) or die(mysql_error());

// Fetch data

$sql="SELECT * FROM scoreboard WHERE codcliente = '".$q."' OR lower(nombre) LIKE '%".strtolower($q)."%'";
$result = mysql_query($sql);
if(mysql_num_rows($result) == 0){
  echo '<div align="center" style="background-color:#CCCCCC; font-weight:bold; color:#C0504D;">Record no existe.&nbsp;&nbsp;&nbsp;<input id="srchcreate" type="button" value="Crear" /></div>';
  return;
  }
//echo $result;

// Construct the table

echo "<table id='srchtable' class='srchtable'>";

// Construct the array

while($row = mysql_fetch_array($result)){
  echo "<tr>";
  echo "<td align='center'>" . $row['codcliente'] . "</td>";
  echo "<td align='left'>" . $row['nombre'] . "</td>";
//  echo "<td align='center'>" . $row['ejecutivo'] . "</td>";
//  echo "<td align='center'>" . $row['banca_as400'] . "</td>";
//  echo "<td align='center'>" . $row['banca_real'] . "</td>";
//  echo "<td align='right'>" . $row['ingresos'] . "</td>";
  echo "<td align='center'>" . $row['ciiu'] . "</td>";
//  echo "<td align='center'>" . $row['division'] . "</td>";
  echo "<td align='left'>" . $row['actividad'] . "</td>";
  echo "<td align='center' class='{$row['riesgo_industria']}'>" . $row['riesgo_industria'] . "</td>";
  echo "<td align='center' class='{$row['riesgo_cliente']}'>" . $row['riesgo_cliente'] . "</td>";
  echo "<td align='center'>" . $row['fecha'] . "</td>";
  echo "<td align='center'>" . $row['analista'] . "</td>";
  echo "<td align='center'>" . "<input id='edit' type='button' value='Editar' onclick='' />" . "</td>";
  echo "</tr>";
}
echo "</table>";

?>

结果看起来像这样：Screenshot。我的问题是，当我单击“Editar”（编辑）按钮时，如何使这些字段可在线编辑？也许在前面放置一个选项输入<td>来选择要编辑的行？编辑后，如何将更改插入 MySQL？谢谢！

for your first question, you dont need the checkbox. If you dont mind jquery, you can use

$(this).closest('tr')

to get the row the edit button that was clicked is in. You can then replace the contents of each cell you want to edit with an input. Wrap your table in form tags and use ajax to submit.

Something to get you started...

$(document).ready(function(){
        $(".edit").click(function(){
            var tr = $(this).closest("tr");
            var submit = "<input type='submit' name='Submit' value='Submit' />";

            tr.find(".td").each(function(){
                var name = $(this).attr("title");
                var value = $(this).html();
                var input = "<input type='text' name='"+name+"' value='"+value+"' />";
                $(this).html(input);
            });

            tr.find(".button").html(submit);

        });
    });

Assuming your table/form looked something like:

<form id="form" name="form" action="#">
        <table>
            <tr class="row">
                <td class="td" title="first_name">John</td>
                <td class="td" title="last_name">Smith</td>
                <td class="button" title="button"><button class="edit">Edit</button></td>
            </tr>
            <tr class="row">
                <td class="td" title="first_name">Roger</td>
                <td class="td" title="last_name">Jones</td>
                <td class="button" title="button"><button class="edit">Edit</button></td>
            </tr>
        </table>
    </form>

You'd then need to do the ajax submit and remove the inputs/revert back to text.
