“jquery.unobtrusive-ajax.js”过时了吗？

Question

I have an ancient MVC2 solution that I migrated to MVC5 (Visual Studio 2013).

I'd like to update the old libraries used in the project with the new ones.

I have by eg. the jquery.unobtrusive-ajax.js library. Is it obsolete as by now?

I ask because that library references

/// <reference path="jquery-1.4.4.js" />

but I upgraded the jQuery (I use the jQuery v1.8.3 by now).

If it with what to replace (like jquery.validate.unobtrusive.js (?))

PS.
In a default MVC project Visual Studio 2013 proposes the folowing "validation" scripts:

jquery.validate-vsdoc.js
jquery.validate.js
jquery.validate.min.js
jquery.validate.unobtrusive.js
jquery.validate.unobtrusive.min.js

Answer 1

jquery.unobtrusive-ajax.js is a Microsoft library for supporting @Ajax.* helpers, this is a plugin that unobtrusively sets up jQuery Ajax .

If you use @Ajax helpers in your code, like ActionLink or BeginForm , along with updating jQuery you have to update the Microsoft jQuery Unobtrusive Ajax , otherwise you can remove it.

If you remove reference to the jquery.unobtrusive-ajax.js , @Ajax helpers will be working as regular @Html helpers.

How can I know if I still use them?

Try to look for the usages of these methods.

You were asking how you can make sure whether you have the latest jquery-unobtrusive-ajax.js installed (or how to check whether it may be obsolete).

Visual Studio 2010+ comes with the NuGet package manager console (PMC). To see if your project's external references (like, eg, unobtrusive AJAX) are still up to date:

1. Open your project in Visual Studio
2. Right-click your project in Solution Explorer
3. Select "Manage NuGet packages"
4. Select the package you want to update (unobtrusive AJAX a/o unobtrusive validation)
5. Here you can see whether you're using the latest version of the external reference or if an update is available.
6. Press the [Update] button.
