Three pages are in the same window, namely main.htm, left.htm and right.htm.
main.htm

Copy code The code is as follows:

 
Achieve cross- 
 > 
 
left.htm

Copy code The code is as follows:

left

I am on the left

right.htm

Copy code The code is as follows:

right

See inside right.htm
function onclickRefresh() is implemented through parent.frames["left"].location.refresh(); The right page refreshes the left page.

If you add

to the main page, copy the code and the code is as follows:

You can access it through the home page Refresh the subpage.
Although this can be super simple to achieve the purpose, in actual projects, the data will not be so simple. The most common is the left and right trees. The creation and loading of the directory tree (such as creating a thousand nodes) is inherently more resource intensive. . If we still use the method to refresh the left and right pages, the efficiency is obviously low, then is it possible to achieve cross-domain refresh or submission through other methods?

What I am thinking of is partial loading of data through ajax. Instead of loading the entire tree. In addition, local data can also be updated through jquery's json processing method.
I wonder if there is any other more efficient method? When loading a tree of 1,000 nodes, the efficiency is worth thinking about.
