javascript - How do the JS of two pages call each other?

Question

Now there are two pages. I want to click OK on the left page to refresh the right page. These two pages are at the same level. How to implement this?

Answer 1

Put this code on the page:

window.onstorage=function(e){
    location.reload();
}

aPage code:

<button onclick="change()">刷新</button>

function change(){
    localStorage.time=new Date().getTime();
}

Answer 2

If it is two sub-pages under a parent page, it can be achieved

Answer 3

This should not be possible. I think your requirement should be for the server to actively push messages, such as using websocket

Answer 4

Listening to your expression, it sounds like that. Click on the left menu bar to load the back page.
A common and simple method is to nest an iframe on the back side. Of course, the other way is to use pajax

Answer 5

No matter how I think about it, I feel that this is a side navigation, like the one that many people have with a navigation bar on the left or right side of their blog. The other one is the iframe mentioned above. After speaking, the Sheriff returns the votes!

Answer 6

This doesn’t work. Each page of the browser has a different interface, and it does not provide js with an interface for communication. If two pages need to interact, the most feasible way is websocket.

Answer 8

From what you said, you used the frame code to introduce different pages.
<FRAMESET cols = "280,*" frameborder=yes bordercolor=silver>

     <FRAME SRC="modifyMenu!showTreeMenu" NAME="menuTree" SCROLLING="No" id="leftTree">  
     <FRAME SRC="showModifyMenu.jsp" NAME="main" SCROLLING="AUTO" id="showModifyMenu">  

lt;/FRAMESET>

function init(){

//leftTree是左边Frame的id  
//重新加载这个页面  
window.parent.frames[ "leftTree"].location.reload();  

}

You can try this method.

Answer 9

It sounds like a nested iframe page. . .
