如何在 jQuery 中访问 serializeArray 创建的值?
要访问 serializeArray 创建的值,请使用 serializeArray( ) 方法。serializeArray( ) 方法会序列化所有的表单和表单元素,例如 .serialize() 方法,但会为你返回一个 JSON 数据结构供你处理。
假设我们的 serialize.php 文件中包含以下 PHP 内容 −
<?php if( $_REQUEST["name"] ) { $name = $_REQUEST['name']; echo "Welcome ". $name; $age = $_REQUEST['age']; echo "<br />Your age : ". $age; $sex = $_REQUEST['sex']; echo "<br />Your gender : ". $sex; } ?>
以下是一个展示此方法用法的示例 −
