javascript - Ask for advice: How to display the originally hidden div of page 2 when linking from page 1 to page 2?

Question

Can it be done purely using js and html?
One way that comes to mind is to use the form on page one to pass parameters, and page two to judge the parameters to determine whether p is displayed.
But how are the parameters passed by action received by page 2?

     if(r!=null)return  unescape(r[2]); return null;
}

One more thing, CSS3’s :target pseudo-class selector can also implement this function, mainly using anchor points
