jQuery V3.0+中的.load（）不工作/意外结果

Question

我试图有一个引导模式显示的页面加载，但相反，我得到一个空白的白色屏幕。

我使用的是ASP.NET核心，我希望模式显示当我的视图加载。

我使用$(document).ready而不是$(down).load尝试了相同的模式，它工作得很好。我知道这对我的bootstrap和jquery不是问题，因为我在php中尝试了这个模式，它可以工作。

我的代码如下

null

$(window).load(function() {
    $('#myModal').modal('show');
  });

Answer 1

$(...).LOAD应为$(...).ON('load',...

在jQuery 3.0之前，.load()侦听load事件，但从那时起，.load()的目标是：

从服务器加载数据，并将返回的HTML放入匹配的元素中。

正如jQuery所描述的：

在jQuery3.0之前，事件处理套件还有一个名为.load（）的方法。旧版本的jQuery根据传递给它的参数集来确定激发哪个方法。

.load()文档

null

$(window).on('load',function() {
  $('#myModal').modal('show');
});
