Use javascript to convert external link styles-JS Tutorial-php.cn

Use CSS attribute selectors to selectively control link styles, such as adding a small icon to all external links to identify them as external links.

　But there are disadvantages to using CSS:

　1. It only supports browsers such as Firefox that have good support for web standards.

　2. It can only judge links, not anchor points or javascript. If you encounter it, there is nothing you can do.

This can be done with js. First write a style:

The following is a reference fragment:
a.other:link,a.other:visited,a.other:active
{
background:url("external.gif ") no-repeat top right;
padding-right:15px;
}

Write another js, but the js should take into account the diversity of links, such as the Javascript, anchor points, etc. mentioned above. If it's an image link, don't apply a style.
