我的网站上有表格问题。我想当你点击提交按钮时,按钮消失,因此用户无法点击两次,导致表格提交两次。我试图改变功能,但我不想放弃加载图标显示。我可以添加其他功能并将代码添加到
onsubmit="showHide(); return true;"
?那么它执行2个功能?提前谢谢!
<script src="https://www.google.com/recaptcha/api.js?hl=nl" async defer>
</script>
<script
type="text/javascript">
function showHide() {
var div = document.getElementById("hidden_div");
if (div.style.display == 'none') {
div.style.display = '';
}
else {
div.style.display = 'none';
return false;
}
}
</script>
<style>
div.g-recaptcha {
margin: 0 auto;
width: 304px;
}

您可以为提交按钮的div块提供新的Id,并可以在同一个函数中编写逻辑。不需要其他功能。
<div id="hidden_div1" style="display:block">
<input type="submit" value="Voorstellen" name="submit">
</div>
并在你的showHide()函数中:
var div1 = document.getElementById("hidden_div1");
div1.style.display='none';

id必须是唯一的。为按钮提供单独的ID。此外,您需要使用防止默认行为,否则隐藏按钮的代码将不会执行
function showHide(e) {
e.preventDefault()
var div = document.getElementById("hidden_div_button-container");
if (div.style.display == 'none') {
div.style.display = '';
} else {
div.style.display = 'none';
return false;
}
}
div.g-recaptcha {
margin: 0 auto;
width: 304px;
}
<script src="https://www.google.com/recaptcha/api.js?hl=nl" async defer>
</script>
<form name="form2" method="POST" onsubmit="showHide(event); return true;" action="/BESTANDEN/phps/JocanasNLsuggest.php">

另一种选择是隐藏按钮而不是隐藏它
