通过xmlHttpRequest获取file.php的执行结果

Question

I'm calling a file.php using XMLHttpRequest in javascript:

index.html

<script type="text/javascript">

    var xhr = new XMLHttpRequest();
        xhr.onload = function(){ 
            console.log(xhr.responseText);
        };

        xhr.open("GET", "file.php", true);
        xhr.send();

</script>

file.php

<?php echo "123";

---

I expected 123 as result string but instead I got <?php echo "123"; which is the file.php content.

Am I using the XMLHttpRequest right? What am I missing?

Answer 1

Sounds like your server isn't set up correctly and isn't executing the script with the PHP parser.

What happens when you request the page without XMLHttpRequest (ie, just enter the url in the browser)?
