今天记录一个功能，提交表单的数据给后端，提交表单时候的请求参数差不多是这样子的，其中有单选框，下选框，（下拉框可以选择一个值，也可以选择多个值），以字符串数组的格式提交。
请求报文如下
{"questionContent":"题目1","correctAnswer":"正确答案","otherAnswer1":"错误答案1","otherAnswer2":"错误答案2","otherAnswer3":"错误答案3","userGrades":["kinderGarten","firstGrade","threeGrade","sixGrade"],"questionCategory":"简单"}
具体提交格式需要注意：
1：input输入框提交类型为字符串
2：radio只能单选，每次只能提交一个，类型为字符串
3：下拉框（年级）为数组，当选择一个option或者多个option的时候，格式都为字符串数组形式。
点击按钮，会出现一个弹框，在弹框里面有form表单，填写表单数据，再次点击确定的时候，调用一下保存的接口，将填写的数据提交给后端。
