JS method to determine whether 360 Secure Browser has extremely fast core_javascript skills

The example in this article describes the JS method to determine whether the 360 ​​Safe Browser has a high-speed core. Share it with everyone for your reference. The specific analysis is as follows:

360 Safe Browser’s extremely fast core, the navigator.userAgent on non-360 websites is:

"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1", all using the native Google Chrome userAgent;

And the navigator.userAgent of 360’s own website is

: "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.89 Safari/537.1 QIHU 360SE", which contains 360's own logo;

So it is difficult to know the 360 ​​ultra-fast core during our own development process;

The following method is extracted from a plug-in in a front-end blog. This method can determine the extremely fast core of 360 Secure Browser

Copy code The code is as follows:

function is360se(){
var where = "suffixes", value = "dll", name = "description", nameReg = /fancy/;
var mimeTypes = window.navigator.mimeTypes, i;
for (i in mimeTypes) {
If (mimeTypes[i][where] == value) {
If (nameReg.test(mimeTypes[i][name])) return false;
}
}
Return true;
}

I hope this article will be helpful to everyone’s JavaScript programming design.
