覆盖jQuery验证MVC4中的默认设置 [英] Override jQuery validate default settings in MVC4

问题描述

要覆盖查询验证插件，请在普通文档中，推荐方式是:

To override the Query validate plugin, in the plaugsin document, the recommend way is:

$(".selector").validate({
    invalidHandler: function(form, validator) {
      var errors = validator.numberOfInvalids();
      if (errors) {
        var message = errors == 1
          ? 'You missed 1 field. It has been highlighted'
          : 'You missed ' + errors + ' fields. They have been highlighted';
        $("div.error span").html(message);
        $("div.error").show();
      } else {
        $("div.error").hide();
      }
    }
})

但是，它在带有jquery-1.7.1.js的MVC4中不起作用.看来jquery.validate.unobtrusive.js阻止了覆盖句柄被调用.如果不包括此文件，则会调用覆盖句柄并显示消息.有人遇到同样的问题吗?

However, it does not work in MVC4 with jquery-1.7.1.js. it seems jquery.validate.unobtrusive.js prevent the override handle to be called. If do not include this file, the override handle is called and message is displayed. Anybody have the same issue?

推荐答案

我终于按照布鲁斯.诀窍是先删除旧的处理程序，再连接您的自定义处理程序.您可以用相同的方法覆盖其他设置. Microsoft应该加快修复其jquery.validate.unobtrusive.js使其与jquery.validate一起使用的速度.据报道不引人注目的[version ="2.0.20710.0"]会破坏jquery-1.9.0 .

I finally make it work as suggested by Bruce. The trick is to remove the old handler before hookup your custom one. You can override other settings the same way. Microsoft should speed up to fix its jquery.validate.unobtrusive.js to work with jquery.validate. It has been reported unobtrusive [version="2.0.20710.0"] breaks jquery-1.9.0.

$('form').each(function() {
    $(this).unbind("invalid-form.validate"); // remove old handler!!!!
    $(this).bind("invalid-form.validate", function(e, validator) {
        //alert("ok");
        var errors = validator.numberOfInvalids();
        if (errors) {
            var message = errors == 1
                ? 'You missed 1 field. It has been highlighted'
                : 'You missed ' + errors + ' fields.  They have been highlighted';
            $("div.error span").html(message);
            $("div.error").show();
        } else {
            $("div.error").hide();
        }
    });
});
