Javascript location object

Location -- location is used to obtain or set the URL of a form and parse the URL. It is one of the most important objects in Bom.

• LocationThe meaning of Chinese "location"
• URL: http://www.dreamdu.com/javascript/window.location/
• Location is both the property of the window object and the property of the Document Object.
• Location contains eight attributes, 7 of which are part of the URL of the current form. The remaining and most important is the href attribute, which represents the URL of the current form.
• The eight attributes of location are both readable and writable, but only the href and hash attributes are supported.WriteMake sense. For example, change location. href locates a URL and modifies the location. hash will jump to the anchor (<a id = "name"> or <Div id = "ID">) name tag on the current page (if any ), and the page will not be reloaded.

Note: The two addresses of different protocols or hosts cannot reference the location object of each other. This is a security requirement. For example, the current window opens a page under "www.a.com", and another window (Object Name: bwindow) opens a webpage of "www. B .com. If "bwindow. Location" is used in the current window, an error occurs: "No permission ". This error cannot be handled.Program(Event handler, refer to onerror events) to receive and process events.
