In .net development, it is a good thing to make full use of free controls, but if you cannot modify the controls to meet your own needs, you must use JS. The premise is to study the method attributes of various objects in the browser model. Especially if you are familiar with CSS and HTML, you will be able to do it very cool. As far as the JS language itself is concerned, the requirements are not high.

1. Tips for dynamically deleting the contents of Table. No need to write too much code. One line:

tb.removeNode(true)

2. Dynamically add rows, except CreateElement The method can also be shorter like this:

<table id=tb1></table>
<SCRIPT>
function addTable(){
var row1 = tb1.insertRow();
var cell1=row1.insertCell();
var cell2=row1.insertCell();
cell1.innerText="Baby Gray Bean";
cell2.innerText="Super Big 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. To delete Table in DIV, simply Div.innerHTML="".
The above are some practical and relatively short codes. Of course, there are various other ways to achieve it, but they are generally longer than the above, such as combining the insertAdjacentHTML method of the DIV object, etc. Different methods are used under different needs. The premise is to study well Method attributes of various objects of the browser model. Especially if you are familiar with CSS and HTML, you will be able to do it very cool.
