How to use base url or php variable in javascript file

Question

I am new in PHP, i want to use "base_url"(php variable) in javascript file,But right now i am unable to load image,Here is my current code,How can i do this ? Thanks in advance.

$('#site-logo').find('img').attr( {src:'<?php echo base_url(); ?>assets/images/logo/[email protected]',width:'151',height:'45'} );

Have you checked the value base_url returns? It should contain the trailing slash too. An easy way probably would be just a relative URL: '/assets/images/logo/[email protected]', no need for PHP. — Teemu

@Teemu: actually i need to give "dynamic url" (base_url) which mentioned in "config.php" so thats why i want to use php variable,hope you understand my point — Ritika mishra

So what does the JavaScript code this generates actually look like? Did this piece of code even get sent through the PHP parser in the first place? — C3roe

try to use "" for <?php tag and also concat that string to it also check if the final url generating is targetting the asset or not — Rohannn Singh

You can create a variable or a constant in the javascript and store the base url there and use the same in the code.

Something along the line of following

var BASE_URL = "<?php echo base_url(); ?>";

$('#site-logo').find('img').attr({src: BASE_URL+'/assets/images/logo/[email protected]',width:'151',height:'45'});
