感谢您抽出宝贵时间来查看我的问题。
我有两个不同的window.open请求，具体取决于用户单击移动按钮还是摄像头按钮。
单击移动按钮时，mobcamWindow将以特定（小）大小打开
单击摄像头按钮时，摄像头窗口将以其他（大）尺寸打开
这些窗口将打开且尺寸正确，但是，如果在打开（较小）mobcamWindow的同时单击网络摄像头按钮，则我希望当前的mobcamWindow关闭并且新的（较大）webcamWindow以正确的尺寸打开，并且反之亦然。
当前，窗口不会关闭，但是URL将分别更改为正确的mobcamWindow和webcamWindow，但是窗口将保持相同大小。
我试图做不起作用的window.resize，并且window.close也不起作用。
我的代码如下。 （我有两个函数来处理每个mobcamWindow和webcamWindow，每个函数中都有一个IF语句，以检查mobcamWindow或webcamWindow是否打开，如果关闭，则将其关闭。
var webcamWindow = null; // global variable
var mobcamWindow = null; // global variable
function openStreamPopupWebcam(elem) {
if(webcamWindow == null || webcamWindow.closed)
/* if the pointer to the window object in memory does not exist
or if such pointer exists but the window was closed */
{
if(mobcamWindow){
mobcamWindow.close();
}
/*if mobile window is open, close mobile window*/
webcamWindow = window.open(elem.href, "window", "width=470,height=320,resizable,status").focus();
/* then create it. The new window will be created and
will be brought on top of any other window. */
}
}
function openStreamPopupMobile(elem) {
if(mobcamWindow == null || mobcamWindow.closed)
/* if the pointer to the window object in memory does not exist
or if such pointer exists but the window was closed */
{
if(webcamWindow){
webcamWindow.close();
}
/*if mobile window is open, close mobile window*/
mobcamWindow = window.open(elem.href, "window", "width=445,height=666,resizable,status").focus();
/* then create it. The new window will be created and
will be brought on top of any other window. */
}
}
如果您需要更多信息或难以理解，请询问，我将尽力解释。
谢谢。
最佳答案
满足这些条件时，您必须将值重新初始化为“ null”
var webcamWindow = null; // global variable
var mobcamWindow = null; // global variable
function openStreamPopupWebcam(elem){
if(webcamWindow == null || webcamWindow.closed){
if(mobcamWindow){
mobcamWindow.close();
mobcamWindow = null;
}
webcamWindow = window.open(elem.href, "window", "width=470,height=320,resizable,status").focus();
}
}
function openStreamPopupMobile(elem){
if(mobcamWindow == null || mobcamWindow.closed){
if(webcamWindow){
webcamWindow.close();
webcamWindow = null;
}
mobcamWindow = window.open(elem.href, "window", "width=445,height=666,resizable,status").focus();
}
}
