甜蜜的警觉。 在警告框中显示倒计时

Question

I have an issue with displaying the countdown in sweetalert message. After click i use the "A message with auto close timer". I want that countdown to be in the message and user can see the countdown.

swal({  
    title: "Please w8 !",
    text: "Data loading...",
    timer: 10000,
    showConfirmButton: false 
});

Answer 1

It is impossible to do with SweetAlert. It doesn't support counting on UI. But never say never :-)

I have prepared a little hack, which can help you to do that. Just add the code below to your application, and you will see live counting mechanism. And don't forget to add jQuery too.

var
    closeInSeconds = 5,
    displayText = "I will close in #1 seconds.",
    timer;

swal({
    title: "Auto close alert!",   
    text: displayText.replace(/#1/, closeInSeconds),   
    timer: closeInSeconds * 1000,   
    showConfirmButton: false 
});

timer = setInterval(function() {

    closeInSeconds--;

    if (closeInSeconds < 0) {

        clearInterval(timer);
    }

    $('.sweet-alert > p').text(displayText.replace(/#1/, closeInSeconds));

}, 1000);

Result:

Here is better solution

var timer = 10, // timer in seconds
    isTimerStarted = false;

(function customSwal() {
    swal({  
        title: "Please w8 !",
        text: "Data loading..." + timer,
        timer: !isTimerStarted ? timer * 1000 : undefined,
        showConfirmButton: false
    });
    isTimerStarted = true;
    if(timer) {
        timer--;
        setTimeout(customSwal, 1000);
    }
})();
