javascript - SweetAlert2 更新用户反馈计数器

Question

有没有办法更新 SweetAlert2 警报上的文本以显示在一个很长的 JavaScript 循环中已处理的行数？不幸的是，人们已经离开了页面，然后只有一半的行被保存。

我想我也许可以使用 jQuery 类型语法，但不确定正确的选择是什么。

$('#rowsprocessed').text(count);

swal({
    title: 'Save Order.',  
    input: 'checkbox',                    
    inputValue: 0,
    inputPlaceholder: 'Remove Zero(s) Quantity Item(s) Before Saving the Order?',
    html: 'For large templates this may take a few moments. This message will automatically close when the process is complete.',
    type: 'info',
    showCancelButton: true,
    confirmButtonText: 'Submit',
    showLoaderOnConfirm: true,
    preConfirm: function(checkbox) {
        return new Promise(function(resolve, reject) {
            removeZeros = checkbox;

            setTimeout(function() { 
                swal.showLoading();
                $.post("/components/com_sails/views/neworderform/saveOrderHeader.php",
                        {
                            orderid: orderid,
                            accountid: accountid,
                            buyerid: buyerid,

                            cancelDate: cancelDate
                        },
                        function (result) {
                            if (result.return == 1) {                           
                                // assign order id to holder field
                                $('#orderInput').jqxInput('val', result.ordernbr);

                                // loop through our rows and save depending on the removeZero marker
                                var rows = $('#jqxgrid').jqxGrid('getdisplayrows');
                                var rowsToRemove = [];
                                var linessaved = 0;


                                for (var i = 0; i < rows.length; i++) {
                                    var row = rows[i];

                                    // get row info for delete 
                                    if ((removeZeros == 1) && row['quantity'] == 0) {
                                        rowsToRemove.push(row.uid);
                                    }

                                    // run database update 
                                    $.ajax({
                                        type: 'POST',

                                        // if there is a problem what do we do????

                                        if (rowSaveData.return == 1) {                                                          
                                            $('#rowsprocessed').text(i);

Answer 1

当然可以，您只需通过 {html: "..."} 传递一个附加元素即可用作更新用户的方式。

类似的东西:

{
    ...
    html: 'For large templates this may take a few moments. This message will automatically close when the process is complete.<br/><span class="swal2-    status"></span>',
    ...
}

然后使用以下语法进行更新:

var $status = $('.swal2-status');
$status.html("I'm an update");
