JavaScript loads immediately

Execute now

Externally referenced JS file, if you want him to take effect immediately after loading the page, you need to precede the method with parentheses, and write the value after the method. As follows:

(function (wenben) {    alert (wenben);} (" if you can see me, prove I'm in effect ")

Prevent compression

In front of the JavaScript method add:!. You can prevent JavaScript compression from executing an exception immediately. As follows:

! function (wenben) {    alert (wenben);} ("If you can see me, prove I'm in effect")
