我正在嘗試使用SweetAlert2。它工作,當我不想通過$ _POST發送一些數據。但是當我想通過$ _POST發送數據時,sweetalert只會出現在不到一秒的時間,然後消散,並且不管用戶選擇何種形式發送。Sweetalert2不返回true/false
我該如何修改我的代碼,當我想要定期窗口確認,當用戶點擊「刪除」時,表單將被髮送,否則當他點擊「取消」時,表單會不會發送?
if(isset($_POST['submit'])) {
echo 'Your form was submitted.';
}
<form action="#" method="post>
<label>
<span>Username</span>
<input type="text" value="" name="username" />
</label>
<input type="submit" name="submit" value="Register!" id="test-1" />
</label>
</form>
<script>
document.querySelector('#test-1').onclick = function(){
swal({
title: 'Are you sure?',
text: "You won't be able to revert this!",
type: 'warning',
showCancelButton: true,
confirmButtonColor: '#3085d6',
cancelButtonColor: '#d33',
confirmButtonText: 'Yes, delete it!'
}).then(function() {
swal(
'Deleted!',
'Your file has been deleted.',
'success'
)
})
//IF SWAL => DELETE -> send form
//ELSE IF SWAL => CANCEL -> do nothing
//when I put here "return false;", then sweetalert is working, but it doesn't send the form
</script>
解決方案由於新手:
<?php if(isset($_POST['send']))
{echo 'Your form was submitted.';} ?>
<form id='myfrm' action="#" method="post">
<label>
<span>Username</span>
<input type="text" value="" name="username" />
<input type="hidden" name="send" value="send">
</label>
</form>
<button value="Register!" id="test-1"> submit </button>
<script>
document.querySelector("#test-1").onclick = function(){
swal({
title: "Are you sure?",
text: "You won't be able to revert this!",
type: "warning",
showCancelButton: true,
confirmButtonColor: "#3085d6",
cancelButtonColor: "#d33",
confirmButtonText: "Yes, delete it!"
}).then(function() {
document.querySelector("#myfrm").submit();
})
}
</script>
謝謝,新手!但是它仍然不起作用(或者僅僅從部分 - 它成功地詢問用戶,如果他想刪除它;但.then(function()不起作用)的第二部分:http://avcr1.chudst。 cz/test.php – chudst
您可能會使用舊版本的sa2或sa1,它們在選項中使用回調函數,因此基於promise(then())語法在這些版本中不可用請參見[here](https:// jsfiddle.net/mmw6azgh/)它應該如何工作在最新版本 – Viney
我認爲,我使用的是最新版本(6.2.0)。而且你是正確的,「警報」是可以的,所以問題不是在「.then(function()」中,但直接在「document.querySelector('#myfrm')。submit();」 - 表單仍然沒有發送數據。 – chudst
