Text to JavaScript Converter
This article provides a one-page text to JavaScript converter. The conversion is done with PHP. The converted JavaScript is for saving to an external file. The code for importing the file is also generated.
Upload the text to JavaScript converter on your website where it's handy for whenever you need it.
The content published with JavaScript may be a word, a phrase, a paragraph, and even other JavaScript.
Reasons For Using JavaScript
There are a few reasons to use JavaScript for publishing certain content on web pages:
A. Hiding content from robots and spiders.
JavaScript content generally is not seen by robots and may not get indexed by search engine spiders, especially when the JavaScript is imported from an external file.
-
Certain words or phrases in the content, if indexed, may have a detrimental affect on the web page's search results position.
-
Certain words or phrases in the content may cause search engine algorithms to mark the web page as a bad neighborhood.
-
If the content is an ad or something else with views counted, the logs will better represent actual views.
B. Publishing certain content only for browsers with JavaScript enabled.
Here are a few reasons for publishing certain content only if the browser has JavaScript turned on.
-
To publish links to games or other content that can work only with JavaScript.
-
To hide forms from spammers' automatic submission robots.
-
To publish content only when the page is loaded in a certain browser.
C. To defeat source code page copying thieves.
When the entire web page source code is copied for use somewhere else, the JavaScript to import an external file is also copied.
The .htaccess file can be used to take control if the web page source code is published on another domain.
The Defeating Source Code Page Copying Thieves blog post tells you how.
