技术细节

说明

open() 方法将查找已经存在的窗口或者打开新的浏览器窗口。如果 name 参数指定了已经存在的窗口，则返回对该窗口的引用。返回的窗口将显示 url 参数指定的文档，但忽略 features 参数。在只知道窗口名称的情况下，这是 JavaScript 获得对那个窗口引用的唯一方式。

如果没有指定 name 参数，或者它指定的窗口不存在，那么 open() 方法将创建新的浏览器窗口。这个新窗口将显示 url 参数指定的 URL，它的名称由 name 指定，大小以及控件由 features 参数指定。如果 url 是空串，那么 open() 将打开新窗口。

name 参数指定新窗口的名称。这个名称中只能够出现数字、字母或下划线。它可以作为标记 和 的 target 属性的值，用来迫使文档在这个指定的窗口中显示。

当使用方法 Window.open() 给已有的指定窗口装载新文档时，可以给它传递 parameter, used to declare whether the new document has its own entry in the window's browsing history or replaces the current document's entry. If 参数，用来声明新文档是在窗口的浏览历史中拥有自己的条目，还是替换当前文档的条目。如果 parameter, used to declare whether the new document has its own entry in the window's browsing history or replaces the current document's entry. If replace If the value is true, the new document will replace the old document. If the value is false, or omitted, then the new document will have its own entry in the window's browsing history. The function provided by this parameter is similar to Location.replace() method

Please do not confuse Window.open() methods are very similar to the features provided by Document.open() method, to make your code clear, it is best to use Window.open(), and do not use open(). In the event handler defined as an HTML attribute, the function open() is usually interpreted as Document.open(), so in this case, you must use Window.open().

Window features

features is a list of features to be displayed in the window, separated by commas. If the value of this optional parameter is empty or it is omitted, the window will display all features. However, if features specified a feature, then the features that do not appear in this list will not be displayed in the window. It should be noted that this string does not contain any spaces or whitespace, and the format of each element is as follows:

feature[=value]

For most features,value The value is yes or no. The equal sign and value The values can be omitted, and if the feature appears, it is assumed that its value The value is yes, and if it does not appear, it is assumed value The value is no. However, the width or height value The value is required, and you must specify their pixel values.
