Open the same window multiple times using JavaScript
提问by Ching Ling
I'm new to JavaScript and trying to learn. How can I open the same window multiple times using JavaScript? Also, it didn't work when I changed the function name.
我是 JavaScript 新手，正在努力学习。如何使用 JavaScript 多次打开同一个窗口？此外，当我更改函数名称时它不起作用。
Here is the function:
这是函数：
<script type='text/javascript'>
function window(URL) {
day = new Date();
id = day.getTime();
eval("page" + id + " = window.open(URL, '" + id + "', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=600,height=800,left = 650,top = 250');");
}
</script>

Try something like this:
尝试这样的事情：
var numWindows = 0;
var windows = new Array(100);
var parameters = "toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=600,height=800,left = 650,top = 250";
function openNewWindow(url) {
numWindows += 1;
var title = "Window #"+numWindows;
windows[numWindows] = window.open(url, title, parameters);
}
To access the windows, do this:
要访问窗口，请执行以下操作：
windows[num]
where num is the id of the window. The first id is 1, the second is 2, and so on.
其中 num 是窗口的 id。第一个 id 是 1，第二个是 2，依此类推。

Use a random number to open a popup as many times as you want:
使用随机数根据需要多次打开弹出窗口：
function openPopUp (url) {
var randomno = Math.floor((Math.random()*100)+1);
window.open(url,'PopUpWindow'+randomno,'scrollbars=1,menubar=0,resizable=1,width=850,height=500');
}

The 2nd parameter of window.open() (here it's the timestamp) must be different, otherwise window.open() will load the new window inside the existing(opened before with the same name->that's what the 2nd parameter assigns to the window).
window.open() 的第二个参数（这里是时间戳）必须不同，否则 window.open() 将在现有窗口中加载新窗口（之前用相同的名称打开-> 这就是第二个参数分配给窗户）。
You can also use "_blank"as 2nd parameter for open()
您还可以使用“_blank”作为 open() 的第二个参数

Try omitting with id parameter, like so:
尝试省略 id 参数，如下所示：
<script type='text/javascript'>
function window(URL) {
window.open(URL,'','toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=600,height=800,left=650,top=250');
}
</script>

First, I would strongly encourage you to abandon using eval. It's very unsecure and not good to use.
首先，我强烈建议您放弃使用 eval。它非常不安全且不好使用。
Second, you can accomplish this without eval like so:
其次，您可以像这样在没有 eval 的情况下完成此操作：
function openWindow(URL) {
day = new Date();
id = day.getTime();
windowCol[id] = window.open(URL, id,
'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=600,height=800,left = 650,top = 250');
}
And just to avoid confusion, even though "window" works as a function name, I'd suggest changing it to make the code more readable as it may get confused with the global window object.
并且为了避免混淆，即使“window”用作函数名称，我还是建议更改它以使代码更具可读性，因为它可能会与全局窗口对象混淆。

Try this.
试试这个。
<script type='text/javascript'>
function window(URL) {
window.open(URL, "_blank", 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=600,height=800,left = 650,top = 250');
}
</script>
