如何防止打開多個彈出窗口？

Question

我的問題是下一個。

我要防止在第一個彈出窗口處於活動狀態時打開第二個彈出窗口。 我想在2個以上的窗口（模態）上實現此目標，比方說5或6。

有人知道我該怎么做到嗎？

我感謝您的幫助。

這是代碼：

// When everything is ready...
$( document ).ready(function() {

// Modal 1 mechanism:
$('.trigger_1').click(function(e) {

$('.x_1').click(function() {
$('#popup_1').fadeOut() });

function modal1() {

// Modal 2 mechanism:

Answer 1

放置以下條件以防止多個彈出窗口打開：

function modal1() {
    if ($("#popup_2").is(":hidden")){
        $('#popup_1').fadeIn();
    }
    else{/*do something*/}
}


function modal2() { 
    if ($("#popup_1").is(":hidden")){
        $('#popup_2').fadeIn();
    }
    else{/*do something*/}
}

更好的方法是使用類：

function modal(element){
    if ($(".pop_up_open").length == 0){
         $(element).fadeIn();
         $(element).addClass("pop_up_open");
    }
    else{/*do something*/}
}
function modalClose(){/*this function will run when you want to close function*/
         $(".pop_up_open").fadeOut();
         $(".pop_up_open").removeClass("pop_up_open");
}

代替許多功能，使用這些功能彈出要打開和關閉的元素。

$(document).ready(function () {
    $('.trigger_1').click(function (e) {
        e.preventDefault();
        modal("#popup_1");
    });
    $('.x_1').click(function () {
        modalClose();
    });
    $('.trigger_2').click(function (e) {
        e.preventDefault();
        modal("#popup_2");
    });
    $('.x_2').click(function () {
        modalClose();
    });
    $('.trigger_3').click(function (e) {
        e.preventDefault();
        modal("#popup_3");
    });
    $('.x_3').click(function () {
        modalClose();
    });
});
