Browser Detection Method 1. Object Feature Detection: a common method for determining browser capabilities. This method can be used if you are more concerned with the browser's capabilities and do not care about its actual identity. The common native Ajax write method uses this method to create XMLHttpRequest:Copy codeThe Code is as follows: IXHR: function (){If (window. ActiveXObject ){XHR = new ActiveXObject ('Microsoft. xmlhttp ');} Else if (window. XMLHttpRequest ){XHR = new XMLHttpRequest

Therefore, when a site needs to obtain the user's current geographic location, the browser will prompt "allow" or "deny ". First, let's look at which browsers support the Geol

In fact, it is not difficult to achieve, we first the implementation process to think about, first of all, if the navigation in the scope of the display, you do not have to make changes. When the navigation is out of range, that is, the distance from the top of the screen is less than 0, we have to float it on the top of the screen, and then more than 0, to do a recovery operation, the principle is so simple, roughly look at the effect of the picture Copy Code code as follows: $ (

At this stage, our RN practice is based on the published app, such as replacing a sub-module that enters from a portal into an RN page. Then we can design this submodule as a generic RN container, and all RN pages jump inside the RN container. RN container in iOS using Uiviewcontroller, Android using activity or fragment, load bundle files, normally, a module only one bundle file. To achieve the page jump, we can use the Navigator component, the spe
