PHP中的外部.js文件语法问题

Question

I looked around but couldn't find an answer to my current issue.

I want to echo a PHP variable into my external .js file. I then use the PHP variable in a javascript variable and from here use ajax to send the variable/s to my database. I believe I am using incorrect syntax for the php echo. My javascript

content = '<div class="post">' + '<img src="<? echo $pic ?>" />' + '</div>';

Is this possible to echo the PHP variable to the external .js file? Am I using the right syntax in the javascript variable?

Answer 1

Your server will not parse the .js file as PHP. You could name your js file as a .php file, and then use header("Content-type: application/javascript") .

Answer 2

Normally, your httpd is only set to parse files named 'foo.php' for PHP code; name the file foo.php instead of foo.js and manually set the content type:

<?php header('Content-type: application/javascript');?>
content = '<div class="post">' + '<img src="<? echo $pic ?>" />' + '</div>';
