innerHTML in IE and FF, Chrome, opera browse under the HTML nominal name is not the same size

Today, when you get the option element in select and then convert the option character to an Li character through a regular expression, you can succeed in Chrome FF Opera, or the option character under IE.

Use the alert () Pop-up box to print out the printed HTML element tag names in uppercase.

That's how it's written:

Optionsui = optionsui.replace (/(option)/g, "Li");

After the changes are written like this:

Optionsui = optionsui.replace (/(option)/gi, "Li");

At first it didn't take into account that the HTML tag signature obtained under IE was capitalized. So there is no addition to I.

Attach a note about the RegExp modifier

IE effect label signature is uppercase:

The Chrome effect label signature is lowercase:
