JAVASCRIPT

JAVASCRIPT PROMPT FUNCTION

The prompt() function is used to take an input from a user. It takes and optional text description/instruction as it's argument.

Example:

prompt("Please enter your name");

A prompt will then appear with an instructions of: Please enter your name and a text box for input.

To see a practical application of this, the following example combines a prompt with an alert (try this out for yourself). It prompts you for your name and then alerts a message with your name.

<script type="text/javascript">

var name = prompt("Please enter your name");
if(name !='')
{
alert("Hello " + name);
}

</script>
