我正在使用System variable screenshot,如果金额字段为空,我正在尝试显示错误。
当我第一次尝试输入金额时,它没有问题。
当我第一次尝试将字段留空时,我收到验证错误。之后,当我写一个金额并单击提交按钮验证错误不会消失。它被卡住不会第二次验证。这是sweetalert2 v7.0.0。如果你能给我指路,我将不胜感激。我在哪里做错了?
<a href="#" class="refundbutton"><i class="fa fa-undo"></i> Refund</a>
$(".refundbutton").click(function(){
swal({
title: 'Enter Refund Details',
html:'<label for="ipt" class=" control-label"><span class="oval">1</span> Select refund type</label><select class="form-control refund_type"><option value="4"> Credit Card </option> <option value="5"> Cash </option></select>' +
'<label for="ipt" class=" control-label"><span class="oval">2</span> Enter refund amount</label><input type="text" class="form-control nDiscount_fixed" autocomplete="off" style="height: 34px;" value="">',
showCancelButton: true,
confirmButtonText: 'Submit',
preConfirm: function (value) {
return new Promise(function (resolve, reject) {
if ($(".nDiscount_fixed").val() === "") {
swal.showValidationError(
'please enter a refund amount.'
)
}
resolve([ $('.refund_type').val(), $('.nDiscount_fixed').val() ])
})
}
}).then(function (result) {
var swalrebateamount = parseFloat($('.nDiscount_fixed').val()).toFixed(2);
if (swalrebateamount !="" && swalrebateamount !="0" ) {
//some code
}
}).catch(swal.noop)
});
答案 0 :(得分:5)
您必须重置验证错误。 more details
if ($(".nDiscount_fixed").val() === "") {
swal.showValidationError(
'please enter a refund amount.'
)
}
else
{
swal.resetValidationError();
}
