The ASP. NET MVC Bundle uses

Basic use

Global.asax

protected void Application_Start ()        {            bundleconfig.registerbundles (bundletable.bundles);        }

Bundleconfig

 Public Static voidregisterbundles (bundlecollection bundles) {bundles. ADD (NewScriptbundle ("~/bundles/jquery"). Include ("~/scripts/jquery-{version}.js")); Bundles. ADD (NewScriptbundle ("~/bundles/bootstrap"). Include ("~/scripts/bootstrap.js",                      "~/scripts/respond.js")); } 

View

@Scripts. Render ("~/bundles/jquery") @Scripts. Render("~/ Bundles/bootstrap")

2 ways to enable bundle (merge compression)

1. in bundleconfig registerbundles method Add the following code

    public  static  void   Registerbundles (bundlecollection bundles) {bundles. ADD ( new  scriptbundle ( " ~/bundles/jquery   ). Include (  ~/scripts/jquery-{vers    Ion}.js    //  enable merge compression  Bundletable.enableoptimizations = true   

3. Open web.config The file, set the debug=false compiled

     <system.web>    <compilation debug="false" targetframework=" 4.5 " />  </system.web>

Change Effect

The number of requests is reduced after merging, which in contrast increases the loading speed of the page.

Precautions

• Merge compressed files by default cache for one year. If you repeatedly open the Web page and the configured file is not modified, the server returns an HTTP 304 status code so that the browser loads the files in the cache.

• Picture path problem, after merging multiple CSS together, sometimes causes the picture to fail to load

  Workaround: Use absolute path for picture

• BundleConfig Compressed files configured in the configuration are A.js (uncompressed versions), and a.min.js files exist in the same directory. When you modify the A.js file, you want to merge the compressed JS file also contains the modified content, but not as we would like, the compressed JS file or reference to the contents of the A.min.js, previously modified does not appear in the compressed JS file. Similarly, CSS is the same.
