当页面被重定向时，如何在正在加载的页面的 innerhtml 中使用 javascript 变量？

Question

foo() {
    var fooVar=7;
    location.assign("otherPage.php");
    otherPageobject.html=fooVar;
}

Answer 1

The code running on one page can't affect anything on another page, because only one page can be loaded/active at a time. What you can do is send your value to that next page. For example:

location.assign("otherPage.php?fooVar=" + fooVar);

Then in that other page you can get the value from the query string and use it as you see fit.
