This article describes how to use JavaScript to obtain browser information and how to obtain browser addresses and parameters. For more information about browser information, see the navigator object in Window. we can use a series of API functions to learn browser information. The JavaScript code is as follows: Function message () {txt ="Browser code name: "+ navigator. appCodeName +""; Txt + ="Browser na

This article describes how to use JavaScript to obtain information icons of various browsers. For more information, see How to obtain browser Information Window has a navigator object to let us know all the information about the browser. We can use a series of API functions to know the information about the browser. The JavaScript code is as follows: The Code is as follows: function message(){ txt = " Browser code name: "+

Javascript: use JavaScript to detect browser-related features. Javascript tutorial I. Check the browser nameProblem:Different browsers have different standard support for javascript. Sometimes you want the script to run well on different browsers. In this case, you need to check the browser and determine its name, write scripts for different browsers.Solution:Use the appName attribute of the navigator object.For example, to check whether the browser i

Detecting a browser is an important task in writing cross-browser js programs. From time to time, we need to write branch code for different browsers.The following is an example:Copy codeThe Code is as follows:// Add the event tool functionFunction addEvent (el, type, handle ){If (el. addEventListener) {// for standard browsesEl. addEventListener (type, handle, false );} Else if (el. attachEvent) {// for IEEl. attachEvent ("on" + event, handle );} Else {// otherEl ["on" + type] = handle;} }1,The

){......;} Else {Window. location. href = '/';}}} But this does not work. The original ff 3 is changed to xmlHttp. onreadystatechange = xmlHandle (); however, with parentheses added, IE does not work. Alas, FF was originally regarded as a chicken skin. Now I feel that FF is purely named as a "standard support, it is a waste of time for programmers. However, this program is really important, and there is no way to debug it again to see if there is a simpler way, as shown below:Copy codeThe Code

Detecting a browser is an important task in writing cross-browser js programs. From time to time, we need to write branch code for different browsers.The following is an example: Copy codeThe Code is as follows: // Add an event tool function Function addEvent (el, type, handle ){ If (el. addEventListener) {// for standard browses El. addEventListener (type, handle, false ); } Else if (el. attachEvent) {// for IE El. attachEvent ("on" + event, handle ); } Else {// other El ["on" + type] = handle;

Bridging mode is a structural design pattern. Design intent: Separate the abstract and implementation parts so that they can be independently changed. When you see the design intent, you may be a little confused, we see that the inheritance and interface are not both abstract and implementation of separation. In particular, interfaces and abstract classes are such implementations. Then why is there such a bridging separation? Let's look at an example first. For example: The car brand built-in

Detect JS Code of various browsers and Systems The Code is as follows: Var sUserAgent = navigator. userAgent;Var fAppVersion = parseFloat (navigator. appVersion );Function compareVersions (sVersion1, sVersion2 ){Var aVersion1 = sVersion1.split (".");Var aVersion2 = sVersion2.split (".");If (aVersion1.length> aVersion2.length ){For (var I = 0; I AVersion2.push ("0 ");}} Else if (aVersion1.length For (var I

Js identifies different browsers Based on userAgent for judgment, jsuseragent Check the browser, pay attention to the browser judgment order, mainly based on userAgent for judgment. // Check the browser var client = function () {var engine = {ie: 0, gecko: 0, webkit: 0, khtml: 0, opera: 0, ver: null }; var browser = {// viewer ie: 0, firefox: 0, safari: 0, konq: 0, opera: 0, chrome: 0, ver: null}; var ua = navigator. userAgent; // the browser checks i

detecting the user proxy string. The user agent string contains a large amount of information related to the browser, including the browser, platform, operating system, and browser version. The user proxy string has a long history. During this period, the browser provider view adds some deceptive information to the user proxy string to cheat the website details. User proxy detection requires special skills, especially when Opera conceals the user proxy string. Even so, the user agent string can

This article provides a detailed analysis of the implementation code of the browser for js detection. For more information, see writing cross-browser js programs, browser detection is a very important task. From time to time, we need to write branch code for different browsers.
