Add an example to remove a table

Add the Onclick response function for all the a nodes of the #employeetable:
* 1. Pop-Up confirmation dialog: Are you sure you want to delete xx information? XX is the TR of the TD where the current a node is located
* The text value of the first TD child node, and to remove the front and back spaces
* 2. If you click "Confirm", delete the row where the A node is located

Attention:
* 1. A node is a hyperlink that can cancel the default behavior by returning false in its OnClick event
* 2. The direct parent node of TR is tbody, not table
* 3. You can write a trim (str) function to the code that removes the space before and after it.

Add the onclick response function for the #addEmpButton:
* 1. Gets the value of the #name, #email, #salary text box
* 2. Creates 3 TD nodes with the text value obtained from 1, creating a TR node. And put the above 3 TD
* Node price TR Node Sub-node
<tr>
<td>Tom</td>
<td>[email protected]</td>
<td>5000</td>
</tr>
* 3. When creating a TD node: <td><a href= "Deleteemp?id=xxx" >Delete</a></td>
* 4. The TD created with 3 is also added as a sub-node of tr.
* 5. The TR is then added as a child node of the Tbody child node of the #employeetable.
* 6. Add the Onclick response function to the a child node of the newly created TR so that it also has the ability to delete.
