Show/Hide Elements
Automatically update your pages
There are certain times that you want to dynamically show or hide elements based on a user's selection. Luckily, this is quite easy with javascript.
NOTE: These functions use the getObject() function that I have described on the previous page. If you do not include this function in your script, the code will not work at all and will return an error.
function showElement(el) {
getObject(el).style.display = '';
}
function hideElement(el) {
getObject(el).style.display = 'none';
}
Thats it! Whenever you want to show your element, just call the showElement() function and pass it the id of the element. To hide the element, call the hideElement() function.
