我有自定义方法
$.validator.addMethod("lettersandspaces", function(value, element) {
var value = this.elementValue(element).replace(/\s+/g, ' ').trim();
return this.optional(element) || /^[a-zA-Z][a-zA-Z\s]*$/i.test(value);
}, 'Your name may only contain letters');
这里我修剪空白并用只有一个替换任何重复的空格。然后我验证确保只有字母和空格。
是否可以使用表格而不是用户输入的内容提交剪裁value
?

使用submitHandler,您可以在提交表单之前采取任何措施,(form.submit())
请参阅beleow一个工作片段
$.validator.addMethod("lettersandspaces", function(value, element) {
var value = this.elementValue(element).replace(/\s+/g, ' ').trim();
return this.optional(element) || /^[a-zA-Z][a-zA-Z\s]*$/i.test(value);
}, 'Your name may only contain letters');
$(document).ready(function () {
$("#form").validate({
rules: {
"name": {
required: true,
minlength: 5,
lettersandspaces: true
},
"age": {
required: true,
}
},
messages: {
"name": {
required: "Please, enter a name"
},
"age": {
required: "Please, enter your age",
}
},
submitHandler: function (form) { // for demo
var newName = $("#name").val().replace(/\s+/g, ' ').trim()
$("#name").val(newName);
$(form).valid();
alert("Name = '"+newName+"'");
// comment return and uncomment form.submit(
return false; //form.submit();
}
});
});

以jquery的验证形式。如果要在验证之前更改值输入名称。试试看:
$('#form').validate({
rules: {
'name': {
normalizer: function(){
return $('#name').val().(/\s+/g, ' ').trim();
}
}
}
})
