Question

Dynamic form

Asked by: Dennie

Hi,

By clicking on a value in a table the value can be edited. I've got the following code. Somehow the created form isn't posted. How can I get this working?

function edit(parent,goal_id){
 
		var td_goal = parent.getElementsByTagName('TD')[1];
		var value_goal = td_goal.innerHTML;
		td_goal.innerHTML = '<form id="form" method="POST" action="home.php?page=doelen">'+
							'<input type="hidden" name="goal_id" value="' + goal_id + '">'+
							'<input size="30" name="goal" type="text" value="' + value_goal + '">';
		
		//goal description
		var td_desc = document.getElementById(parent.nextSibling.id).getElementsByTagName('TD')[1];
		var value_desc = td_desc.innerHTML;
		td_desc.innerHTML = '<textarea style="width: 800px" name="desc">' + value_desc + '</textarea><br>'+
							'<input style="font-size: 8pt;" type="submit" value="Wijzig">'+
							'</form>';
		
	}

Can you give me more detail information about your table?

 

by: DenniePosted on 2009-10-06 at 00:26:53ID: 25502516

The table is very simple, it is generated from PHP and filed with data from MySQL.

It is something like this. So when I press the edit button an input field is shown for the name and the description.

<table>
      <tr>
            <td>edit button</td>
            <td>name</td>
            <td> remove button</td>
      </tr>
      <tr>
            <td></td>
            <td>Description</td>
            </td</td>
      </tr>
 etc.
</table>

By putting the form tags around the table a was able to fix the problem. But I'm still curious how I could fix this without moving the form tags!

@govindarajan78
There were no javascript errors

 

by: KravimirPosted on 2009-10-06 at 02:15:25ID: 25503054

An HTML element may only have one parent. It seems that you're trying to place one "form" element inside two different table-cells.

The solution would be to put the table inside the form. Either you could put the form element in statically, or you could use actual DOM methods to add it to the document and then move the table into it.

Tools like Firebug (http://getfirebug.com/) can be used to make sure that the structure is created as you intended.

Let me know if you would like more details about anything I mentioned.
