Usually our website will load some js code, statistics ah, Google advertising ah, baidu alliance ah, ali mother advertising code ah, a pile, finally make the page load slowly, slowly. Solution: switch to a js included method to double the loading speed of javascript. Put the usual loading method:

<script src="xxxx.js"></script>

Change into:

<script type="text/javascript">
document.write("<scr"+"ipt src="xxx.js"></sc"+"ript>")
</script>

If you want to load more than one js, you can use the following method

<script type="text/javascript">

document.write("<scr"+"ipt src="xxx1.js"></sc"+"ript>") ;
document.write("<scr"+"ipt src="xxx2.js"></sc"+"ript>") ;
document.write("<scr"+"ipt src="xxx3.js"></sc"+"ript>") ;
</script>

Other js do the same, advertising, page effects… A few last words:

with

<<script type="text/javascript">>
document.write("<<scr"+"ipt src="xxx.js"></sc"+"ript>>")
<</script>>

The way, also can achieve on demand according to the conditions to load your JS file:

<<script type="text/javascript">>
if (  In a good mood  ) {document.write("<<scr"+"ipt src="xxx.js"></sc"+"ript>>")}
<</script>>
