Article describes how to create a web page that can be viewedby users, who disabled JavaScript support or whose web browserdoes not support it.
There are hundreds of millions of Web surfers today. Each ofthem uses one of multiple web browsers available now. You as aWebmaster create cool web pages that are full of graphic andJavaScript and look very impressive in modern web browsers likeInternet Explorer or FireFox. But ask yourself: "How my cool webpage will look like, if the web surfer use Linx browser (textbased) or just disabled JavaScript support?" You may think thatnumber of Linx browser users is quite small today and you canignore them, but search engines spiders does not supportJavaScript as well. You cannot ignore search engines in themodern world.
There are some safe ways how to handle search engines spidersand web surfers, who does not support JavaScript, at your webpage.
One of the approaches is provided by HTML. It is a NOSCRIPT tag.You can enclose in NOSCRIPT tags HTML code that will bedisplayed in browsers that do not support scripting. You canplace navigation hyperlinks here, if you use JavaScript menu forthis purpose. Instead of content, dynamically generated byJavaScript, you can place some static text between NOSCRIPTtags. NOSCRIPT content is invisible for web surfers, who usemodern web browsers, but it will be very useful for Linx usersand search engines spiders.
The second, more flexible approach, is using of JavaScript. Yes,you can use JavaScript to handle visitors, who does not supportJavaScript. It is simple. You can place at the web page HTMLelements with the content that should be visible for these whodoes not support scripting. Then place at the bottom of the pagesimple script code that sets ".style.display" property to "none"for such elements. Therefore, if your web page is viewed in thebrowser, which supports scripting, script code will be executedand all additional elements become invisible. If your web pageis viewed in the browser, which does not support scripting,script code will be ignored.
So, using these simple approaches, you can handle all possibleweb browsers and provide search engines spiders with additionalrelevant content, which is very important as well.
