从Javascript调用php函数最简单的方法是什么？ [关闭]

All the other AJAX examples I have read involve moving data, using html elements and code for older versions of browsers and are not helping me achieve what I want.

I simply need to call a PHP file from JavaScript when a certain condition is met, there is no action and no data returning/moving. What is the most simple way of calling this php file? I also want to try to avoid using jquery if possible.

if( condition is met)
{
 // call the PHP file
}
else
{
 // other logic
}

I'd love to see the "simplest" answer. Because the easiest one is jquery.

    $.post('yourpage.php',{
    var1 : 'something',
    var2 : 'somethingelse'},
function(return){
   //do something
})

What is eaier?

If AJAX and Jquery are out of the options list you may use an iframe.

if(condition)
{
    document.getElementById('iframeId').src = 'page.php'
}
