javascript - 一个接一个地打开每个 Bootstrap 3 Modal，而不是一起打开

问题描述

从 modal_0 开始，我有无限的模态。

我需要的是在关闭一个模式时打开另一个模式，而不是像下面的代码一样打开所有模式。

那么如何解决呢？

$("#modal_0").on('hidden.bs.modal',function () {
  for(var i = 1; i < 5; i++) {
    $("#modal_"+i).modal({toggle: true, backdrop: 'static',keyboard:false,show:true});
  };
});

解决方案

我使用递归机制为您提供了 3 种模式的示例，希望对您有所帮助：

$(document).ready(function()
{
    startRecursiveModalOpening(0);
});

function startRecursiveModalOpening(modalID)
{
    var modalOptions = {
        toggle: true,
        backdrop: 'static',
        keyboard: false,
        show: true
    };

    // Register listener for modal hidden event one time.

    $("#modal_" + modalID)
        .modal(modalOptions)
        .one("hidden.bs.modal", function()
        {
            var nextModal = $("#modal_" + (modalID + 1));
            
            if (nextModal.length > 0)
                startRecursiveModalOpening(modalID + 1);
        });
}
