Js refresh framework PAGE method. Sometimes you need to control the page content refresh in the framework. The following methods are detailed. For more information, see. Let's look at a simple example:
The following example uses the three pages separated by frame.html?top.html?bottom.html to describe how to do this.
Frame.html consists of two pages (bottom (bottom.html) under the top (top.html#). The Code is as follows:
The Code is as follows:
Frame
Now, let's assume that top.html (the page above) has seven buttoners to refresh bottom.html (the page below). You can use the following seven statements to see which one is easy to use.
Statement 1. window. parent. frames [1]. location. reload ();
Statement 2. window. parent. frames. bottom. location. reload ();
Statement 3. window. parent. frames ["bottom"]. location. reload ();
Statement 4. window. parent. frames. item (1). location. reload ();
Statement 5. window. parent. frames. item ('bottom '). location. reload ();
Statement 6. window. parent. bottom. location. reload ();
Statement 7. window. parent ['bottom ']. location. reload ();
The code for the top.html page is as follows:
The Code is as follows:
Top.html
The following is the source code of the bottom.html page. to verify that the page below is refreshed, a dialog box is displayed after the page is loaded.
The code for the bottom.html page is as follows:
The Code is as follows:
Bottom.html
This is the content in bottom.html.
Explanations:
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.
