A single <script> tag can link to an external resource using the src attribute OR contain inline JavaScript code, but it can't do both at the same time. If you specify a src attribute any content between the <script src="foo.js"> tag and the </script> tag is ignored.

Since you want to load the external JS file, and then execute some JavaScript code, you'll need two separate tags to do so:

<script src="../a.js"></script>
<script>
    // your code
</script>

Try

you are not closing script tag

<script src="../a.js"></script>
                       ^//added closing script tag
<script>
var u=document.URL; var i='t4527878445'; m_web(u,i);
</script>

to alert what you pass use

function m_web(u,i) {
    alert(i);
    alert(u);
}

plz write your code like below

<script src="../a.js"></script> </script>
   //^^^^^^^^^^^^^^^^^^ first close script tag of linked js file
<script type="text/javascript">// then call your inline jscode
var u=document.URL; var i='t4527878445'; m_web(u,i);
</script>
