javascript - can we remove dom table? - Stack Overflow|江阴雨辰互联

i have to switch in between two table as per users choice i can do it using table object model but there is problem with it as i remove one table and load another it will work but next time when i have switch back to first it will not get table ids and its not working.

while working with DOM like this

var tbl1  = document.createElement("table");

tbl1.setAttribute('id','shorttable');

for delete i am using below java script

var b = document.getElementById('shorttable');

document.removeChild(b);

but giving me exception

uncaught Error: NOT_FOUND_ERR: DOM Exception

is there any way to do this using DOM?

@lonesomeday thanks for ur reply but its not working when i call it from other function? what i am trying is like this.

  <html>
  <head>
  <title>test dom</title>
  <script>

  function trackmode() 
{
    // i have to delete other table from this function where it is not working  
    var b = document.getElementById('shorttable');
    alert(b);
    b.parentNode.removeChild(b);

    var body = document.getElementsByTagName("body")[0];


    // creates a <table> element and a <tbody> element
    var tbl     = document.createElement("table");
    tbl.setAttribute('id','tracktable');
    var tblBody = document.createElement("tbody");

    // creating all cells
    for (var j = 0; j < 2; j++) {
        // creates a table row
        var row = document.createElement("tr");

        for (var i = 0; i < 2; i++) {
            // Create a <td> element and a text node, make the text
            // node the contents of the <td>, and put the <td> at
            // the end of the table row
            var cell = document.createElement("td");
            var cellText = document.createTextNode("cell is row "+j+", column "+i);
            cell.appendChild(cellText);
            row.appendChild(cell);
        }

        // add the row to the end of the table body
        tblBody.appendChild(row);
    }

    // put the <tbody> in the <table>
    tbl.appendChild(tblBody);
    // appends <table> into <body>
    body.appendChild(tbl);
    // sets the border attribute of tbl to 2;
    tbl.setAttribute("border", "2");
}


function shortenmode() 
{

     var b = document.getElementById('tracktable');
b.parentNode.removeChild(b);

    var body1 = document.getElementsByTagName("body")[0];
    // creates a <table> element and a <tbody> element

To remove an element, you need to remove it from its parent, not from the document. So:

b.parentNode.removeChild(b);
