是否可以在不使用AJAX的情况下以Javascript运行PHP代码？

Question

How to convert JavaScript variable to php variable without using of AJAX inside the JavaScript function.

 function getProduct(category)
{
    document.galaxy.action = '<?php echo JRoute::_('index.php?option=com_virtuemart&view=category&virtuemart_category_id=11') ?>';
    document.getElementById('galaxy').submit();
}

I need to convert js variable "category" to php variable.

Answer 1

This is not posible.

Javascipt is an client-side language, this means that its going to run on the computer of your visitor.

PHP is an server-side language, this means that is going to run on your server.

Answer 2

You can't. What happens when a site is viewed:

1. PHP executes all PHP code on the server
2. The Webserver sends the site to the client
3. The client browser executes JavaScript

When you want use a JavaScript variable with PHP, you have so send it back to the server in some way (AJAX).

Answer 3

var DivVal=document.getElementById('ChkStatus');
       //var InnerVal=DivVal.innerHTML;
       var editRedirect='<?php echo $this->createUrl("Employee/Print"); ?>';
       window.location=editRedirect;

Answer 4

As other people mentioned, you are misunderstanding the concepts a little.

If you want something from your JS sent along with the form to your PHP script you should put it in a form field.

in your form use a hidden value:

<input type="hidden" id="categoryInput" name="category" />

in your JS:

//Before you submit do this..
document.getElementById('categoryInput').value = category;

in your PHP:

$category = $_REQUEST['category'];

EDIT:

Seems like you are asking for this:

document.galaxy.action = '<?php echo JRoute::_('index.php?option=com_virtuemart&view=category') ?>&virtuemart_category_id=' + category;
