Those who make ie6-8 ashamed of the substitution type JS

1,html5shiv

This JS is very simple, can let IE8 identify some new tags, commonly used such as the header Footor section, you can use better semantic tags.

Introduction Method:

    <!-- [If Lt IE 9]>        <script src= ". /.. /scripts/lib/html5.js "></script>    
    <! [EndIf]  -

2,json2.js

He can add Json.parse. json.stringify two JSON serialization deserialization method

Introduce the method, IE8 the following introduction

    <!-- [If Lt IE 8]>        @Scripts. Render ("~/scripts/json2.js")    <![ ENDIF] -

3,jquery

Yes, after 2 jquery, for ie6-8 still have to maintain 1 update, ashamed of it.

Introduction Method:

    <!-- [If Lt IE 9]>        @Scripts. Render ("~/scripts/jquery/jquery-1.11.1.min.js")    <![ ENDIF]-    <!--[if GTE IE 9]>    -- Scripts.render ("~/scripts/jquery/jquery-2.1.1.min.js")    <!--<![ ENDIF] -

4,respond

Respond.js can let ie6-8 support CSS's Media query responsive scheme.

    <!-- [If LTE IE 8]>    @Scripts. Render ("~/scripts/lib/respond/respond.min.js")    <![ ENDIF] -

5,excanvas

He used IE's VML to make the low version IE simulation canvas, the efficiency is much lower.

Case: Baidu Echart Chart control

6.PIE

Allowing Ie6-8 and IE9 to support the CSS3, such as rounded shadow gradients, also uses VML, which has a very low performance cost.

7,flash related JS

Some JS in the low version of IE will use flash as a substitute

Case 1:webuploader Upload Control.

Ie6~9 will use the Flash version, IE10 and other browsers will use the HTML5 version.

Case 2:ckplayer Video Player

He contains both the Flash version and the HTML5 version to be compatible with more browsers.

Conclusion:

I particularly like this type of JS, more use of advanced browser support features such as HTML5 to happy play, and the lower version of IE, the alternative to better the lower version of IE Edge.
