Usually our website will load some JS code, statistics ah, Google ads Ah, Baidu Alliance Ah, Ali mother Advertising code Ah, a heap, finally make the page loading speed is very slow, very slow.
Solution: Change the way a JS contains, so that the JavaScript loading speed doubled.
To load the usual way:
Copy Code code as follows:
<script src= "Xxxx.js" ></script>
Change into:
Copy Code code as follows:
<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
Copy Code code as follows:
<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 is the same, advertising, page effects ...
Finally, a few words of nonsense:
Use
Copy Code code as follows:
<<script type= "Text/javascript" >>
document.write ("<<SCR" + "IPT src=" Xxx.js "></sc" + "ript>>")
<</script>>
The way, but also to achieve on demand according to the conditions to load the JS file you want:
Copy Code code as follows:
<<script type= "Text/javascript" >>
if (in good mood) {Document.writ E ("<<SCR" + "IPT src=" Xxx.js "></sc" + "Ript>>")}
<</script>>
