How to solve the problem that jQuery is not compatible with the lower version of Internet Explorer

Since the release of jQuery, it has stopped the compatibility of IE versions (IE6, IE7, IE8). If you need to be compatible with an earlier version of Internet Explorer, we recommend that you use native JS or an earlier version.

The general way to deal with this is to write two or more sets of js** to the web page to adapt to different versions and different types of browsers, and then use the native js to judge the model and version of the browser to load different js files, the specific implementation method is as follows:

else }

2. Then we click on the lightning bolt icon behind the input box.

3. Then we click on the pop-up window to select "Compatibility Mode".

Internet Explorer:

1. The full name of Internet Explorer is Internet Explorer, which is a popular browser today. When many domestic netizens come into contact with the computer for the first time, they will see an e-like icon on the desktop, and they all use it to open**, this is the IE browser.

2. It is developed by Microsoft and directly bound to Microsoft's Windows operating system, when the user's computer is installed with the Windows operating system, you can use the Internet Explorer to achieve web browsing.

3. At present, it is the first place in the Internet Explorer ranking (accounting for about 65% of the world's browser share).

1. Open IE11 browser, click the "Tools" option in the upper right corner, then select "Internet Options", click the "Security" tab at the top of the interface, and then click "Trusted Sites", add the unopened ** to the trusted site, and then you can try to open it again**.

2. Also open the IE11 browser, click the "Tools" option in the upper right corner, select "Compatibility View Settings" to add the ** that cannot be opened to the "** in Compatibility View", and then close IE11 and reopen it.

2. Click on the "Tools" option, a menu will pop up, and select the "Compatibility View Settings" option from the drop-down menu;

3. After entering the compatibility view settings, fill in the ** that you need to set the compatibility mode, click Add, and finally click Close.

Use the JS framework jQuery to determine the IE browser version to solve the browser compatibility problem.

IE is really something that makes designers hate itchy, and now there are five different versions of IE6, IE7, IE8, IE9, IE10, and there are a little differences. But it can't be helped, you have to accommodate it in order for the page to look the same in every browser.

But now I'm basically reluctant to make compatibility with lower versions of IE. For example, IE6 and IE7 are directly ignored! IE8 is okay.

Fortunately, IE9 and IE10 have compared the support for network standards, and it will be good to wait for IE9 and above browsers to become popular.

But if you don't do compatibility, you don't want to be compatible, you still have to deal with it simply. Luckily, jQuery provides browser tags that allow us to determine which browser and version our visitors are using

12131415 I used a simple example to show the useragent and the current browser, and then tested it in IE 6 8, but the results were really shocking!

As a result, IE 7 is wrong, and a closer look at its useragent reveals that it contains MSIE in addition to MSIE

Therefore, the comparison is problematic. Now that we know the problem, we can solve it.

The first way is a more direct way, which is to determine if there is a higher version in the useragent, that is, it is based on that version

When you want to use it, you can use $It's time to make a judgment. The other is the comparison method of direct correction:

There is no version with IE8 as the dividing line.

All versions of IE are supported in jQuery and below.

The above version no longer supports versions below IE9.

Later versions removed compatibility with older browsers.

IE8 is not supported.

IE8 or less can be used.

The version of jQuery is the last version to support IE 6 7 8, and later versions no longer support IE 6 7 8, so the source of jQuery is much smaller than the previous version.

All versions of IE are supported in jQuery and below.

The above version no longer supports versions below IE9.

IE8 is not supported in later versions, even in previous versions.

All versions of JLiQuery and below should support all versions of IE.

jquery

There are no compatibility issues, JS is there, which means that jQuery supports all browsers.

CDN refers to the version of jquery, and the above version of jquery no longer supports IE8 and below versions of IE browser, so this problem occurs.

The solution is simple:
