JS adds tbody blocks to the table to facilitate the addition and deletion of whole blocks

The use of JS in the table to add tbody block, convenient to add and delete the whole block, the following is added.

<table width= "border=" 1 "cellspacing=" 0 "cellpadding=" 0 "id=" table1 "></table><script language=" JavaScript ">var value =" Content ", var value1 =" <a href= ' * ' >link</a> "; var row = 5; Create 5 rows var col = 7; Create 7-grid var tbody = document.createelement ("tbody"); Create a new element node of type Tbody
var tbody1=document.createattribute ("Tbody1");
for (Var i=0;i<row;i++)   {var tr = document.createelement ("tr");//Create a new element node for the TR type for (Var j=0;j<col;j++) c1/>{  var td = Document.createelement ("TD");//Create a new element node for TD type  td.innerhtml = value1;//link ....  Tr.appendchild (TD);//Add node TD to TR Tbody.appendchild (TR); Add the node tr to tbody}var Parnode = document.getElementById ("table1"); Locate the Parnode.appendchild (TBODY) on the table; Add node tbody to node tail </script>

Once you add a TR, you can use the following
<script>var i=0,arr=new Array (' f9f9f9 ', ' f0f0f0 '); function AddNew () {
var parnode = document.getElementById ("table1"); Navigate to Table Tr=parnode. InsertRow (); tr.style.backgroundcolor=arr[i%2];

Tr.insertcell (). innertext= "Picture" + (++i);
Tr.insertcell (). innerhtml= ' <input type=file name=pic ' +i+ ' class= "Border_index" > <a href=javascript:void (0) Onclick=del () > Delete </a> '
}}

The whole block is only required to remove
<script language= "JavaScript" >
var parnode = document.getElementById ("table1"); Navigate to Table
var tbody;
if (-[1,]) {//Non IE
Tbody=document.getelementsbytagname ("tbody") [0];

}else{//ie
Tbody=document.getelementsbytagname ("tbody") [0];

}

Deleting one TR line at a time can be done in the following ways
<script language= "JavaScript" >
var Parnode=document.getelementbyid ("Table1");
Parnode.deleterow (2);//Remove the third row TR from the table


</script>
