Question

我遇到一些问题，了解如何在打开后引用新的浏览器窗口。例如，如果我从主窗口（index.html）创建3个新窗口：

    var one = window.open( 'one.html', 'one',"top=10,left=10,width=100,height=100,location=no,menubar=no,scrollbars=no,status=no,toolbar=no,resizable=no");

    var two = window.open( 'two.html', 'two',"top=100,left=10,width=100,height=100,location=no,menubar=no,scrollbars=no,status=no,toolbar=no,resizable=no");

    var three = window.open( 'three.html', 'three',"top=200,left=10,width=100,height=100,location=no,menubar=no,scrollbars=no,status=no,toolbar=no,resizable=no");
    two.focus();

如果浏览器“两个”目前处于焦点状态，我怎么能以编程方式关注（或只是引用）浏览器“三”？

Answer 1

我会在父窗口中有一组子窗口。然后，对于每个子窗口，都有一个将子项添加到父项的childWindow数组的函数。这样你就可以拥有任意数量的子窗口。

//In the 'Main' window
var childWindows = new Array();

//In the child window
function onload()
{
    window.parent.childWindows.push(window);

}

window.attachEvent('onload', onload);
//or
window.load = onload
//or with jQuery
$(window).ready(onload)

设置焦点如下：

//In the parent

childwindows[i].focus();

//In a child

parent.childwindows[i].focus();

//or to focus on next child from within a child
var len = parent.childwindows.length;
for (var i = 0; i < len; i++)
{
    if (parent.childwindows[i] && parent.childwindows[i] == window) //you might want some other way to determine equality e.g. checking the title or location property.
    {
        var n = (i + 1) % childWindows.length;
        childwindows[n].focus();
    }

}
