I've seen a couple of questions in regards to bootstrap modals, but none exactly like this, so I'll go ahead.(我已经看过几个关于bootstrap模态的问题，但没有一个完全像这样，所以我会继续。)
I have a modal that I call onclick like so...(我有一个模态，我打电话就像这样......)
$(".modal-link").click(function(event){
$("#modal-content").modal('show');
});
This works fine, but when I show the modal I want to focus on the first input element... In may case the first input element has an id of #photo_name.(这工作正常，但是当我显示模态时我想要关注第一个输入元素...在可能的情况下，第一个输入元素的id为#photo_name。)
So I tried(所以我试过了)
$(".modal-link").click(function(event){
$("#modal-content").modal('show');
$("input#photo_name").focus();
});
But this was to no avail.(但这无济于事。) Lastly, I tried binding to the 'show' event but even so, the input won't focus.(最后，我尝试绑定到'show'事件，但即便如此，输入也不会集中。) Lastly just for testing, as I had a suspiscion this is about the js loading order, I put in a setTimeout just to see if I delay a second, will the focus work, and yes, it works!(最后只是为了测试，因为我怀疑这是关于js加载顺序，我放入一个setTimeout只是为了看看我是否延迟了一秒，焦点是否有效，是的，它有效！) But this method is obviously crap.(但这种方法显然是废话。) Is there some way to have the same effect as below without using a setTimeout?(有没有办法在不使用setTimeout的情况下获得与下面相同的效果？)
$("#modal-content").on('show', function(event){
window.setTimeout(function(){
$(event.currentTarget).find('input#photo_name').first().focus()
}, 0500);
});
