Does not work isset post in dynamically created submit
问题
我有PHP文件中的代码：
<form id="form_id" action="" method="post">
<?php if (isset($_POST["123"])) {echo "BUTTON WORKS";}?>
</form>
<script src="file.js"></script>
我有JS文件中的代码：
let testButton = document.createElement("submit");
testButton.innerHTML = "Click it";
document.getElementById("form_id").appendChild(testButton);
testButton.name = "123";
PHP代码不起作用。为什么？
