I am building an ASP.NET MVC 4<\/code> based application and try to follow the code from the standard internet template where’s possible.<\/p>\n

Yesterday I started to implement my forms and noticed that I don’t get a client side validation and the content is always submitted.<\/p>\n

I render the form like this:<\/p>\n

@using (Html.BeginForm(new { ReturnUrl = ViewBag.ReturnUrl }))\n{\n    @Html.AntiForgeryToken()\n    @Html.ValidationSummary(true)\n\n        <\/code><\/pre>\n
    \n
  • @Html.LabelFor(m => m.Title)
    \n@Html.TextBoxFor(m => m.Title)
    \n@Html.ValidationMessageFor(m => m.Title)<\/code><\/li>\n
  • \/\/more list items here<\/code>\n
    and because I didn’t start with the debugging I render the scripts as follows:<\/p>\n
    @Scripts.Render(\"~\/Scripts\/jquery-1.10.2.min.js\")\n@Scripts.Render(\"~\/Scripts\/jquery.validate.min.js\")\n@Scripts.Render(\"~\/Scripts\/jquery.unobtrusive-ajax.min.js\")\n@Scripts.Render(\"~\/Scripts\/jquery.validate.unobtrusive.min.js\")\n<\/code><\/pre>\n
    Then, in firebug, when I submit an incorrect form I get the following error:<\/p>\n
    TypeError: a(...).live is not a function\n<\/code><\/pre>\n
    And then I saw this – Also bear in mind that in jQuery 1.9 the .live() method has been removed which was one of the breaking changes<\/code> an another SO question here. So I decided to try and changed the jQuery version to :<\/p>\n
    @Scripts.Render(\"~\/Scripts\/jquery-1.7.1.min.js\")\n<\/code><\/pre>\n
    and the validation started to work normally.<\/p>\n
    Some further research showed me that most some people made their custom jQuery.val*<\/code> scripts in order to make it work with a new version of jQuery<\/code>.<\/p>\n
    My question is – is there a standard packaged\/bundle for client side validation that I can add to my project and use with newer version of jQuery<\/code> (the one I’m using now is 1.10.2)? Do I have to use jQuery 1.7.*<\/code> for my client validation parts or now there is something else supported by MS<\/code> (like validation using knockout.js<\/code> which is part of the standard template) or maybe even other js library that is now used for client side validation in MVC projects?<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
