此方法是一种通过Ajax.Request将表单序列化并提交到表单操作属性的 URL 的便捷方式。options 参数传递给 Ajax.Request 实例,允许覆盖 HTTP 方法并指定其他参数。
传递给 request() 的选项与底层 Ajax.Request 选项智能合并 –
- 如果表单具有方法属性,则其值用于 Ajax.Request 方法选项。如果将方法选项传递给 request(),则它优先于表单的方法属性。如果两者均未指定,则方法默认为“POST”。
- 在参数选项中指定的键值对(作为散列或查询字符串)将与(并优先于)序列化表单参数合并。
语法
formElement.request([options]);
返回值
它返回一个新的 Ajax.Request。
