You may think that number of Linx browser users is quite small today and you can ignore them, but search engines spiders does not support JavaScript as well. You cannot ignore search engines in the modern world.
There are some safe ways how to handle search engines spiders and web surfers, who does not support JavaScript, at your web page.
One of the approaches is provided by HTML. It is a NOSCRIPT tag. You can enclose in NOSCRIPT tags HTML code that will be displayed in browsers that do not support scripting. You can place navigation hyperlinks here, if you use JavaScript menu for this purpose. Instead of content, dynamically generated by JavaScript, you can place some static text between NOSCRIPT tags. NOSCRIPT content is invisible for web surfers, who use modern web browsers, but it will be very useful for Linx users and search engines spiders.
The second, more flexible approach, is using of JavaScript. Yes, you can use JavaScript to handle visitors, who does not support JavaScript. It is simple. You can place at the web page HTML elements with the content that should be visible for these who does not support scripting. Then place at the bottom of the page simple script code that sets ".style.display" property to "none" for such elements. Therefore, if your web page is viewed in the browser, which supports scripting, script code will be executed and all additional elements become invisible. If your web page is viewed in the browser, which does not support scripting, script code will be ignored.
So, using these simple approaches, you can handle all possible web browsers and provide search engines spiders with additional relevant content, which is very important as well.
