jsによってsubmitを実行した場合、onsubmitは動かない

Last updated at Posted at 2020-08-19
動かない

<form action="" method="post" onSubmit="return check()">
<input type="submit" onClick="action()" />
</form>

<script>

function check() {
  ...
}

funciton action(){
   document.form.submit();
}

</script>

正解はこれ。

動く

<form action="" method="post" onSubmit="return check()">
<input type="submit" id="test" />
</form>

<script>

function check() {
  ...
}

funciton action(){
  document.getElementId("test").onclick;
}

</script>

jsでsubmitボタンをクリックするとonsubmitは起動する。
