How to Show/Hide form fields whenever I select/unselect a checkbox?
Posted: 15 Dec 03 (Edited 15 Dec 03)
Try these code samples:
1) Make an HTML page and place this script inside the HEAD tag:
document.getElementById("hideablearea").style.visibility = "visible";
document.getElementById("hideablearea").style.visibility = "hidden";
2) Put the following code inside the BODY tag:
<form name='frm' action='nextpage.asp'>
<input type="checkbox" name="chkbox" onclick="showhidefield()">
Check/uncheck here to show/hide the other form fields
<div id='hideablearea' style='visibility:hidden;'>
This is a text line below the hideable form fields.<br>
All items inside the DIV tags appear/disappear as you select/unselect the checkbox.
Notice that the line of text below the hideable area stays on the same place whether the
checbox is selected or unselected.
Now, what if we want everything below the hideable area move up to fill-in the gap or unused space
when the area is hidden? Very simple. We just have to make a few changes in our HTML sample:
document.getElementById("hideablearea").style.display = "block";
document.getElementById("hideablearea").style.display = "none";
2) Now, replace the style attribute of the DIV tag with style='display:none'.
Test your modified HTML.
Notice that all items below the hideable area move up to fill-in that gap left by the area when it is hidden.
