How to use Code Igniter to show Dynamic images via javascript(jQuery)
You can use the URL helper in Code Igniter to load CSS and Javascript with the base_url() method, but what if you have images dynamically being placed into your HTML via javascript? for example in my javascript file I've got
var arrowimages={down:['downarrowclass', 'images/down.png', 23], right:['rightarrowclass', 'images/right.png']}
and those images will be placed into whatever menu item I've specified has a drop down menu.
but that file is a .js file so obviously the server won't load php inside of it.
so, how can I set the base ur开发者_StackOverflow社区l for the JS?
Thanks!

Define a constant javascript variable like BASE_URI in the of your view, you can then reference this variable in any of your external javascript files.
<head>
....
<script type="text/javascript">
var BASE_URI = "<?php echo base_url(); ?>";
</script>
....
</head>
External js...
var arrowimages={down:['downarrowclass', BASE_URI+'images/down.png', 23], right:['rightarrowclass', BASE_URI+'images/right.png']}
加载中,请稍侯......
