我正在寻找一个jQuery的插件,可以验证一个键被按下后,它失去焦点(文本框).
我目前正在使用jVal – jQuery Form Field Validation Plugin.它的效果非常好.我唯一的问题是我只能使用一般的错误信息.
例如：
我需要一个2到5个字符之间的字符串.如果它太短,我想显示一条错误消息,表明它很短,同样如果它太长.我知道我可以显示一个错误消息,要求字符串在2到5个字符之间.正在进行的验证更复杂.
任何其他验证器的想法,或者我如何使用这个插件显示唯一的错误消息.
编辑：
验证工具需要防止特定的字母或数字,而不需要表单.
谢谢
解决方法
这一个看起来像适合你的描述：
> jQuery plugin:validation (Homepage)
> demo
> API docs
// validate signup form on keyup and submit
$("#signupForm").validate({
rules: {
firstname: "required",lastname: "required",username: {
required: true,minlength: 2
},password: {
required: true,minlength: 5
},confirm_password: {
required: true,minlength: 5,equalTo: "#password"
},email: {
required: true,email: true
},topic: {
required: "#newsletter:checked",agree: "required"
},messages: {
firstname: "Please enter your firstname",lastname: "Please enter your lastname",username: {
required: "Please enter a username",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 password",minlength: "Your password must be at least 5 characters long",equalTo: "Please enter the same password as above"
},email: "Please enter a valid email address",agree: "Please accept our policy"
}
});
