当用户点击模态窗口之外时，如何使用jquery关闭w3schools示例中的模态窗口？

Question

链接： http://www.w3schools.com/howto/tryit.asp?filename=tryhow_css_modal2

现有代码：

window.onclick = function(event) {
    if (event.target == modal) {
        modal.style.display = "none";
    }
}

根据Jquery改变：

$(window).on('click', function(event){
    if(event.target == $('#myModal')){
        $('#myModal').css({display: "none"});
    }
});

事件正在触发，但是如果条件没有通过。 你能建议如何做到这一点。

关于关闭模态似乎是一个相同的问题，但我的问题是当用户点击模态的外部区域时关闭模态窗口。 How to close a modal by clicking outside the modal window?包含关于用户点击关闭按钮时关闭模态窗口的信息。三江源。

尝试匹配id而非整个对象，

$(window).on('click', function(event){
    if(event.target.id == 'myModal'){
        $('#myModal').css({display: "none"});
    }
});

＆＃13;

＆＃13;

// Get the button that opens the modal
var btn = document.getElementById("myBtn");
var modal = document.getElementById('myModal');

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks the button, open the modal
btn.onclick = function() {
    modal.style.display = "block";
}

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
    modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
/*window.onclick = function(event) {
    if (event.target == modal) {
        modal.style.display = "none";
    }
}*/
$(window).on('click', function(event){
    if(event.target.id == 'myModal'){
        $('#myModal').css({display: "none"});
    }
});
