1. Tips for dynamically deleting the content in the Table. You do not need to write too much code. One line:
Tb. removeNode (true)
2. Add rows dynamically. In addition to the CreateElement method, it can be short as follows:
<Table id = tb1> </table>
<SCRIPT>
Function addTable (){
Var row1 = tb1.insertRow ();
Var cell1 = row1.insertCell ();
Var cell2 = row1.insertCell ();
Cell1.innerText = "Baby gray beans ";
Cell2.innerText = "super stupid wolf"
}
</SCRIPT>
<Input type = "button" VALUE = "AddTable" onclick = "addTable ()">
3. dynamically Add Table in DIV
<SCRIPT>
Function addTable (){
Var tb1 = document. createElement ("table ";
Tb1.border = "1px ";
Var row1 = tb1.insertRow ();
Var cell1 = row1.insertCell ();
Var cell2 = row1.insertCell ();
Mydiv. appendChild (tb1 );
Cell1.innerText = "wanghr100 ";
Cell2.innerText = "panyuguang962"
}
</SCRIPT>
<BODY>
<Div id = mydiv style = "width: 400; height: 300;"> </div>
<Input type = "button" VALUE = "AddTable" onclick = "addTable ()">
4. Delete the Table in the DIV, As long as Div. innerHTML = "" is simple.
The above is part of the relatively short practical code. Of course there are other methods to achieve this, but it is generally longer than the above, such as combining the insertAdjacentHTML method of the div object, etc, the premise of using different methods under different needs is to study the method attributes of various objects in the browser model. It is especially cool to be familiar with CSS + HTML. JS language itself does not have high requirements.
The Document object is used as an example. The related methods include:
Method Description

CreateAttribute
CreateComment
CreateDocumentFragment
CreateElement
CreateEventObject
