Script & noscript tag in html pages

User browser runs client side scripts in the html page. To run the inline script codes we have to keep the code block within <script> and </script> tags. All the codes within these tags will be executed by the (client side) browser. With the introduction of Ajax the script tag is frequently used and client side scripting is playing a major role in developing web pages.

The most common type of script used at client side is JavaScript so we will start our example with one JavaScript code.

<script type="text/javascript">
document.write("Hello World");
</script>

We can keep all the JavaScript code at an external file and just load the same by using SRC attribute. Here is the example.

<script language="javascript" src="code.js"></script>

Here all the code is kept in an external JavaScript file ( .js ) and it is included by src="code.js"

Script execution support

Client browser setting can be changed to not to execute scripts. You can get all details on how to enable or disable script it here. If the script execution is disabled then we can use <noscript> tag and give a message to the user. Here we have used <noscript> html tag. Here is an example.

<noscript>Your browser does not support scripts, you have to enable it to run this page</noscript>

You can see the uses of this at our PHP Ajax section.

No, this is not possible. But you can have control over it by triggering stop code by some time delay or user action. There are some other ways like Ajax by which you can look back to server to control rest of the script. It can better explained by some examples. What is your requirement?
