can we remove dom table?
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 a开发者_如何学JAVAttribute 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
var tbl1 = document.createElement("table");
tbl1.setAttribute('id','shorttable');
var tblBody1 = 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
tblBody1.appendChild(row);
}
// put the <tbody> in the <table>
tbl1.appendChild(tblBody1);
// appends <table> into <body>
body1.appendChild(tbl1);
// sets the border attribute of tbl to 2;
tbl1.setAttribute("border", "2");
//here it will work
//var b = document.getElementById('shorttable');
//alert(b);
//b.parentNode.removeChild(b);
//myP.removeChild(myTextNode);
}
</script>
</head>
<body >
<button type="button" name="website" onclick=trackmode() > track</button>
<button type="button" name="website1" onclick=shortenmode() > short </button>
</body>
</html>
To remove an element, you need to remove it from its parent, not from the document. So:
b.parentNode.removeChild(b);
