jQuery的形式验证是否不允许用户名字段的空间? [英] jquery form validate not allow space for username field?

问题描述

我使用了 http://bassistance.de/jquery-plugins/jquery-插件验证/

我的表单验证:

$("#form_person").validate({
    rules: {


        username: {
            required: true,
            minlength: 2,
            maxlength:15
        },
        password: {
            required: true,
            minlength: 2
        },
        confirm_password: {
            required: true,
            minlength: 2,
            equalTo: "#password"
        },
        email: {
            required: true,
            email: true
        }

    },
    messages: {

        username: {
            required: "Please enter a username",
            maxlength:"max length 15 digits",
            minlength: "Your username must consist of at least 2 characters"
        },
        password: {
            required: "Please provide a password",
            minlength: "Your password must be at least 5 characters long"
        },
        confirm_password: {
            required: "Please provide a confirm password",
            minlength: "Your password must be at least 5 characters long",
            equalTo: "Please enter the same password as above"

    }
});

有人帮助我验证用户名上是否不允许空格吗?

推荐答案

您可以尝试执行以下操作:

you can try something like this:

$(document).ready(function(){

  jQuery.validator.addMethod("noSpace", function(value, element) { 
  return value.indexOf(" ") < 0 && value != ""; 
}, "No space please and don't leave it empty");


$("form").validate({
   rules: {
      name: {
          noSpace: true
      }
   }
  });


})
