如何使用javascript将行输入框添加到现有的html表单中

Question

I have a form which displays rows from a database table and an update button with each row.

I need to add a blank row on a button click (ADD ENTRY) exactly like the ones above in the form and a save button with this row, like above (update button), using JavaScript.

The following is the HTML and the JS I'm using. This is how my page looks like:

<?php

include('adodb/adodb.inc.php');

echo '<h1>Mxpresso Revenue Management Solution</h1>';

echo '<img src="http://mxpresso.com/images/logo.png" alt="mxpresso logo" style="width:171px;height:108px;">';

echo '<h2>See existing records</h2>';

$db=NewADOConnection('mysql');$db->Connect("127.0.0.1", "vc", "abc", "vc");

$sql="select * from rev";
$result = $db->Execute($sql);
if ($result === false) die("failed2");
$records=array();
$count=$result->RecordCount();
echo "Total Records Found :".$count."<br>";

if($count > 0) {
    echo '<style>
          input{
             outline:none;
             border: none;
           }

           </style>

<table id="datatable" class="form" border="1" width="50%">
<col width="10%">
<col width="10%">
<col width="10%">
<col width="10%">
<col width="10%">
<tbody>
<tr>
<th><h4>OfferID</h4></th>
<th><h4>AffID</h4></th>
<th><h4>Deduction</h4></th>
<th><h4>Status</h4></th>
<th><h4>Update Entry</h4></th>
</tr>';

    while (!$result->EOF){
        $offerId=$result->fields[0];
        $affId=$result->fields[1];
        $status=$result->fields[2];
        $deduction=$result->fields[3];                                       

       echo'<form target="_blank" action ="updatecopy.php" id="myform" method="get">


            <tr>        
                        <td><input type="text" name="update_for_offerid" value='.$offerId.'></td>
                        <td><input type="text" name="update_for_affid"  value='.$affId.'></td>
                        <td><input type="text" name="deduct" value='.$deduction.'></td>
                        <td><input type="text" name="status" value='.$status.' ></td>
                        <td><input type="submit" size="23" value="Update Entry" style="color : Black;width:165px"></td>

                    </tr>

                    </form>';
        $rec=array("offerId"=>$offerId,"affiliate_id"=>$affId,"status"=>$status, "deduction"=>$deduction);
        array_push($records,$rec);
        $result->MoveNext(); 
        }
 }

 echo '</tbody>

It may help you.

 $(document).ready(function() { $('a').click(function() { $('#myTable tbody').append('<tr class="child"><td><input type="text"></td><td><input type="text"></td><td<input type="text"></td><td><input type="text"></td><td><input type="text"></td><td>submit</td></tr>'); }); }); 

 input{ width:40px; } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script> <a href="javascript:void(0);">add new</a> <table id="myTable"> <thead> <tr> <td>offerID</td> <td>affid</td> <td>deduction</td> <td>status</td> <td>update entry</td> </tr> </thead> <tbody> <tr> <td>123</td> <td>231</td> <td>12</td> <td>654</td> <td>update</td> </tr> <tr> <td>123</td> <td>231</td> <td>12</td> <td>654</td> <td>update</td> </tr> <tr> <td>123</td> <td>231</td> <td>12</td> <td>654</td> <td>update</td> </tr> </tbody> </table> 

Answer 2

Write an sql query to add data to the table. Then you execute your sql query Example: $SQL= "INSERT INTO table_name (column_name1, column_name2...) VALUES ('$val1', '$val2')"; $exeSQL=mysql_query($SQL) or die (mysql_error());
