我想完成的是自动对焦模态视图。再解释一下。我需要它,当我点击我的网页上的图像,并打开模式视图时,它应该自动关注模式,允许我上下滚动,而不必点击图像将它聚焦到能够使用我的键盘上下滚动。自动对焦模态视图

autofocus属性不会在这种情况下工作,因为这将触发页面加载。但是,您可以使用一些JavaScript轻松解决这个问题。

document.getElementById('modal').focus(); // vanilla JS 
$('#modal').focus(); // jQuery 

一旦模态打开,确保触发其中一个函数。

我都尝试香草JS和JQuery。我尝试在使用modal.display = block显示模态后,在img1.onclick函数中触发vanilla JS。我用JQuery试图做同样的事情。我用alert函数来确保我的触发器正在工作。虽然没有工作。我会继续尝试,我有一种感觉,我正在做一些愚蠢的事情,因此它不像想要的那样工作。 –

你可以试试这个:

$("#myModal").on('shown.bs.modal', function() { 
     $(this).focus(); 
});

您能否告诉我们'shown.bs.modal'的用途是什么?我认为'shown.bs.modal'将用于模态显示或打开时。我试图使用你的功能,但我没有得到积极的结果。 –

对不起,我以为你使用引导模式(我见过'#myModal'并假定它是引导默认值)。这不适用于你在做什么。您是否尝试将焦点应用于模态内的其中一个元素? –

哦,我会查找启动模式,看看是否有效。 B/c我正在使用bootstrap。此外,我将尝试将模式内的某种元素聚焦在下一个模式中。 –
