Common JavaScript code refresh current page

Use location. reload () or location. href to refresh the current page in js. Of course, we can use window. parent. frames to refresh the framework page. Let's take a look.

Reload MethodThis method forces the browser to refresh the current page.

Syntax: location. reload ([bForceGet]) parameter: bForceGet; optional parameter. The default value is false. The current page is retrieved from the client cache. True, the GET method is used to obtain the latest page from the server, which is equivalent to clicking F5 ("refresh") on the client ")

Example

The Code is as follows:

Copy code

<Input type = button value = "Refresh 1" onclick = "window. parent. frames [1]. location. reload ()"> <Input type = button value = "Refresh 2" onclick = "window. parent. frames. bottom. location. reload ()"> <Input type = button value = "Refresh 3" onclick = "window. parent. frames ['bottom ']. location. reload ()"> <Input type = button value = "Refresh 4" onclick = "window. parent. frames. item (1). location. reload ()"> <Input type = button value = "Refresh 5" onclick = "window. parent. frames. item ('bottom '). location. reload ()"> <Input type = button value = "Refresh 6" onclick = "window. parent. bottom. location. reload ()"> <Input type = button value = "Refresh 7" onclick = "window. parent ['bottom ']. location. reload ()">

1. windowless refers to the front page. For example, this refers to the top.html page.
2. parent refers to the parent page of the current page, that is, the framework page containing it. In this example, framedemo.html is used.
3. frames is a window object and an array. Represents all the child pages in the framework.
4. item is a method. Returns the elements in the array.
5. If the sub-page is also a framework page and contains other sub-pages, some of the above methods may not work.
