jQuery函数中的脚本src

Question

I want to do something like this:

            $("#startButton").click(function() {
                <?php if(somecondition){ ?>
                    <script src="some-external-js-srouce"></script>
                    <noscript><img src="irrelevant"></noscript>
<?php } ?>

});

Meaning that I want to execute some external javascript inside a jquery function if a button has been clicked. Can you help me?

Answer 1

You're putting HTML inside JavaScript. That's not quite possible.

You probably want $.getScript to load and execute a script dynamically at runtime. It does not support <noscript> but you're using JavaScript for it anyway, so that does not really make sense to me...

Answer 2

if you want to execute a javascript function from an external file then you can try like this -

<script type="text/javascript" src="myjs.js">
// code that will refer functions of myjs.js

</script>

Answer 3

use jQuery.getScript( url, function(){});
