jQuery验证不相等

Posted 2021-02-24

Adds a method to the jQuery Validation plugin (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) to return false if the field equals a specified string

// Add method
jQuery.validator.addMethod("notEqual", function(value, element, param) {
  return this.optional(element) || value != param;
}, "Please specify a different (non-default) value");
 
// Use example
$("#form").validate({
  rules: {
    nameField: { notEqual: "Your Name" }
  }
});
