如何用jQuery获取关联数组中表单的输入值

<script src="https://cdn.jsdelivr.net/npm/jquery/dist/jquery.min.js"></script>

var formData = {
  name: 'John',
  age: 25,
  email: 'john@example.com'
};

var nameValue = formData.name; // 获取name字段的值
var ageValue = formData.age; // 获取age字段的值
var emailValue = formData.email; // 获取email字段的值

var formData = {
  name: 'John',
  age: 25,
  email: 'john@example.com'
};

for (var key in formData) {
  if (formData.hasOwnProperty(key)) {
    var value = formData[key];
    console.log(key + ': ' + value);
  }
}
