Closing child window from parent window
提问by user2014429
I cant figure out why this won't work. Is there something wrong with this code? The function is being called I checked with an alert but it just won't close the window.
我不明白为什么这行不通。这段代码有什么问题吗？正在调用该函数我检查了警报，但它不会关闭窗口。
$('#click').click(function() {
var win = window.open("test3.html","something","width=550,height=170");
});
function closeit(){
win.close();
}
and on test3.html
并在 test3.html 上
window.opener.closeit();
回答by Ry-
Your winvariable is scoped to the function that handles the click event. Put it in a scope shared by both that function and closeit.
您的win变量范围为处理点击事件的函数。将其放在该函数和closeit.
In this case, that would probably look like:
在这种情况下，它可能看起来像：
var win;
…
$('#click').click(function() {
win = window.open("test3.html", "something", "width=550,height=170");
});
});
function closeit() {
win.close();
}

The first winis a local variable in the callback scope, while the second is a global object. Move the definition (var win) to outside the function and it should work.
第一个win是回调范围内的局部变量，而第二个是全局对象。将定义 ( var win) 移到函数之外，它应该可以工作。
