Hi guys, let's get straight to the problem. First, I have this "deal-post" table (actually <tbody> content is generated dynamically from PHP code, but I omitted it here and make it static for simplicity sake):
<table width="500px" id="deal-post" border="1"> <thead> <tr valign="top" class="column-header"> <th width="35%">Posting</th> <th width="25%">Description</th> <th width="30%">Amount (Rp.)</th> <th width="10%">(%)</th> </tr> </thead> <tbody> <tr valign="top" class="even"> <td>Posting 1<input type="hidden" value="10" name="hidPostCompId[]"/ ></td> <td align="center" style="padding: 0pt 3px;"> <input type="text" class="table-textbox" name="dealDesc[]"/> </td> <td align="center" class="post-amount" style="padding: 0pt 3px;"> <input type="text" class="table-numericbox deal-post" name="dealAmount[]"/> </td> <td align="right" class="post-percent"></td> </tr> <tr valign="top" class="odd"> <td>Posting 2<input type="hidden" value="3" name="hidPostCompId[]"/ ></td> <td align="center" style="padding: 0pt 3px;"> <input type="text" class="table-textbox" value="" name="dealDesc []"/> </td> <td align="center" class="post-amount" style="padding: 0pt 3px;"> <input type="text" class="table-numericbox deal-post" value="" name="dealAmount[]"/> </td> <td align="right" class="post-percent"></td> </tr> <tr valign="top" class="even"> <td>Posting 3<input type="hidden" value="4" name="hidPostCompId[]"/ ></td> <td align="center" style="padding: 0pt 3px;"> <input type="text" class="table-textbox" value="" name="dealDesc []"/> </td> <td align="center" class="post-amount" style="padding: 0pt 3px;"> <input type="text" class="table-numericbox deal-post" value="" name="dealAmount[]"/> </td> <td align="right" class="post-percent"></td> </tr> <tr valign="top" class="odd"> <td>Posting 4<input type="hidden" value="8" name="hidPostCompId[]"/ ></td> <td align="center" style="padding: 0pt 3px;"> <input type="text" class="table-textbox" value="" name="dealDesc []"/> </td> <td align="center" class="post-amount" style="padding: 0pt 3px;"> <input type="text" class="table-numericbox deal-post" value="" name="dealAmount[]"/> </td> <td align="right" class="post-percent"></td> </tr> </tbody> <tfoot> <tr> <td></td> <td align="right">Sell Price :</td> <td align="right" class="post-sell-price"></td> <td></td> </tr> </tfoot> </table> I want to copy the textbox-value in [Amount] column (i give the <td /> a class name="post-amount") to respective index in [Current] column (i give the <td /> a class name="inc-current") as in "deal-summary" table below: <table width="500px" id="deal-summary" border="1"> <thead> <tr valign="top" class="column-header"> <th width="40%">Posting</th> <th width="30%">Total</th> <th width="30%">Current</th> </tr> </thead> <tbody> <tr valign="top" class="even"> <td>Posting 1</td> <td align="right" class="inc-total"></td> <td align="right" class="inc-current"></td> </tr> <tr valign="top" class="odd"> <td>Posting 2</td> <td align="right" class="inc-total"></td> <td align="right" class="inc-current"></td> </tr> <tr valign="top" class="even"> <td>Posting 3</td> <td align="right" class="inc-total"></td> <td align="right" class="inc-current"></td> </tr> <tr valign="top" class="odd"> <td>Posting 4</td> <td align="right" class="inc-total"></td> <td align="right" class="inc-current"></td> </tr> </tbody> <tfoot> <tr> <td align="right">Sell Price :</td> <td align="right" class="inc-sell-price"></td> <td align="right" class="inc-total-current"></td> </tr> </tfoot> </table> It should work like this: when I type the numeric-amount in "dealAmount []" textbox, the value will be showing up instantly in "inc-current" column in "deal-summary" table in the same row index with "deal-post" table. I am so desperate that I have been looking around across the internet, including this forum, but I just can't get the idea. Any help for me will be very appreciated. Thanks! Regards,
