Identify HTML5 Tags:HTML5 added a number of semantically labeled tags, such as Copy Code code as follows: The effect came out, do not want to also know that these several browsers are not recognized these tags, so just appear a line of text: Nav aside;In modern browsers, these two are normal block-level tags, so there are line-wrapping.I risked trying to try and give Nav and aside labels a s

IE9 Browser's privacy protection features are mainly composed of tracking protection, delete browsing history, InPrivate Browsing, web Privacy policy. What is the difference between these privacy precautions? And what about the effect? 　　Tracking protection Tracking protection is mainly to prevent the Web site records the user's personal information, such as personal IP address, geographical location and so on. Many sites add a wide variety of statistical code that, when users visit the site,

To get the calculation style of HTML elements there are always many compatibility issues, there are some differences in browsers, Firefox, WebKit (Chrome,safari) to support the standard of the Consortium method: getComputedStyle (), and ie6/7/ 8 does not support standard methods but has private properties to implement: Currentstyle,ie9 and opera two are supported. With these 2 methods and attributes, you can basically meet most of the requirements.

Browser compatibility issues are an easy to ignore and most important part of the actual development. Before we talk about the old version of the browser compatibility issue, we first need to understand what is ability detection, it is to detect the browser has the ability to determine whether the current browser support to call the properties or methods. Here are a few brief introductions. 1, innertext and innercontent1) innertext and innercontent function the same2) innertext IE8 Browser supp

How to detect browsers with Javascript seems like a cliché. Based on my experience, using Javascript to detect browsers is nothing more than two broad classes of methods. One is to use the feature properties that use the browser. For example, to detect whether the browser supports the getElementById method can be used if (document.getElementById) { The method exists. } else { Do something else } Although

This conclusion comes from an optimization request. At first, the loading of a page was very slow and the load event could not be triggered, therefore, we hope that we can optimize the external resources of the page by dividing static files into domain names, and trigger the load event as early as possible. So I checked the source code of the page and sorted out the external resources. Based on the following two concepts, I drew a speculative waterfall diagram: The browser can only concurrentl

Browser compatibility is the first problem to be solved by the browser development framework in front-end development. To solve the compatibility problem, you must first determine the browser type and version accurately, the browser version can only be known by analyzing the browser's userAgent. today, we will summarize various judgment methods and hope to help you obtain browser information through JS.

CommonJS -- The CommonJS (http://www.commonjs.org/) specification creates a beautiful vision for JavaScript-hopefully JavaScript can run anywhere.I. JavaScript changes and Status Quo tools (browser compatibility) --> components (functional modules) --> frameworks (functional module Organization) --> Applications (business module organization) In practical applications, the performance of JavaScript depends on the degree of API support in the host environment. In the era of Web1.0, only basic sup

Solved the problem of fakepath uploading files in Google browsers, Some time ago, when implementing a file upload function, it was found that mainstream browsers such as Google would change the address of the uploaded file to fakepath for security reasons. For example, a file in drive C, no matter which file it was originally in. After the file is uploaded, it automatically becomes the

Placeholder is a useful property that prompts the user to enter the correct content in the input box, but the IE8 and IE8 browsers do not support this property, and we can use JS to simulate similar effects. Directly below the code:DOCTYPE HTML>HTML>Header>MetaCharSet= "Utf-8">title>Placeholdertitle>styletype= "Text/css">*{margin:0;padding:0;}form{margin:50px;}input{Display:Block;margin:0 0 6px 0;}style>Header>Body> form>User name:inputname= "
