Usually people will use DIV tag to hide and un-hide the control from the html page dynamically. But we can also use pure Java script to hide the controls.
Here I used Java script to hide and un-hide html table rows. I hope this may help some people.
Copy the following content and save it as an html file. Of-course image won't come....;-)
<html>
<SCRIPT type=text/javascript>
function showHideTR(tRow, no, image) {
var tbl,row,img;
if(document.getElementById && document.getElementsByTagName) { //1
tbl = document.getElementById('tblMain');
img = document.getElementById(image);
if(!tbl){
return;
}else{ //2
for (var x = 1; x <= no; x++){ //3
var rowId = tRow+'Child'+ x;
row = tbl.getElementsByTagName('tr')[rowId];
// alert(rowId);
// alert(row);
if(row) {
if(row.style.display != 'none') {
row.style.display = 'none';
if(img){
img.src = "authTable/icon_connect_plus1.gif";
}
} else {
try {
row.style.display = 'table-row';
} catch(e) {
row.style.display = 'block';
}
row.style.display = 'block';
if(img){
img.src = "authTable/icon_collapse_minus1.gif";
}
}
}
}//3end
}//2end
}//1 end
else if(document.all && document.all.tags) {
tbl = document.all.table1;
img = document.getElementById(image);
if(!tbl){
return;
}else{ //2
for (var x = 1; x <= no; x++){ //3
var rowId = tRow+'Child'+ x;
row = tbl.getElementsByTagName('tr')[rowId];
//alert(rowId);
//alert(row);
if(row) {
if(row.style.display != 'none') {
row.style.display = 'none';
if(img){
img.src = "authTable/icon_expand_end.gif";
}
} else {
try {
row.style.display = 'table-row';
} catch(e) {
row.style.display = 'block';
}
row.style.display = 'block';
if(img){
img.src = "authTable/icon_collapse_more.gif";
}
}
}
}//3end
}//2end
}
}
