In order to dynamically set the
element’s style.display property from Javascript code, we need to set a different value for different browsers.
For example, in IE, the Javascript code would be,
tr.style.display = ‘block';
And in Chrome/Firefox, the Javascript code would be,
tr.style.display = ‘table-row';
This means that the Javascript code will have to first do a browser detection and then accordingly set the style.display value.
However, a much simpler solution is to just set the style.display property to nothing – this causes it to assume its default value (which is block for IE and table-row for Firefox, Chrome, etc.)
This is how the much simpler Javascript code would look like,
tr.style.display = ”; // not a double quote, but 2 single quotes
