Javascript checks whether simple instances (recommended) and JS instances are opened in the browser

Recently I have made many HTML5 projects, and many pages will be shared through SNS such as Weibo. Download the company APP on the sharing page. However, in the browsers of many applications, you cannot download the application by clicking the download link. For these browsers, We Need To prompt users to open the sharing page from safari or the browser that comes with the system.Through js, you can determine the browser in which the current page is opened.

The following is an example of code. The comment shows how to determine whether to open in the browser, whether to open in the QQ space browser, and whether to open in Sina Weibo through JS. Of course, you can do a better job. In addition, you can determine whether to enable it on a mobile device or in a PC browser, it can be determined whether it is opened in the android browser or in the IOS browser.

If (browser. versions. mobile) {// determines whether the mobile device is enabled. The browser code is as follows: var ua = navigator. userAgent. toLowerCase (); // obtain the object if (ua. match (/MicroMessenger/I) = "micromessenger") {// open in} if (ua. match (/WeiBo/I) = "weibo") {// open it on the Sina WeiBo client} if (ua. match (/QQ/I) = "qq") {// open in QQ space} if (browser. versions. ios) {// whether to open in IOS browser} if (browser. versions. android) {// whether to open in the android browser} else {// otherwise, it is opened in the PC browser}

Attach the browser code and use the following method to determine many browsers.Including IE browser, operabrowser, Apple browser, Google browser, Firefox browser, etc.

Var browser = {versions: function () {var u = navigator. userAgent, app = navigator. appVersion; return {// mobile terminal browser version information trident: u. indexOf ('think')>-1, // IE kernel presto: u. indexOf ('presto ')>-1, // opera kernel webKit: u. indexOf ('applewebkit ')>-1, // Apple, Google kernel gecko: u. indexOf ('gecko ')>-1 & u. indexOf ('khtml ') =-1, // Firefox kernel mobile :!! U. match (/AppleWebKit. * Mobile. */), // whether it is a Mobile terminal ios :!! U. match (/\ (I [^;] +; (U ;)? CPU. + Mac OS X/), // ios terminal android: u. indexOf ('android')>-1 | u. indexOf ('linux ')>-1, // android terminal or uc browser iPhone: u. indexOf ('iphone ')>-1, // whether the browser is iPhone or QQHD iPad: u. indexOf ('ipad ')>-1, // whether iPad webApp: u. indexOf ('safari ') =-1 // whether the web should program, no header and bottom};} (), language: (navigator. browserLanguage | navigator. language ). toLowerCase ()}

The simple example (recommended) for judging whether to open in the browser is all the content shared by the editor. I hope to give you a reference, and I hope you can provide more support to the customer's house.
