Overwrite window. location and determine whether location is overwritten.

Overwrite window. location and determine whether location is overwritten.

Window in IE. lcoation can be rewritten without re-targeting. The specific method is var location = {}, and then the specific attribute can be rewritten, which brings a certain risk to determine location through js.
How can I determine if location is overwritten? After one afternoon, I tried one of the following methods:

(Location = document. location & location instanceof Location)

This method is only used for IE.

A question about windowlocationhref = windowlocationhref?

The data in the cache used by the browser. not all browsers respond to Windows. location. href = window. location. href. Sometimes the address remains unchanged and the browser does not generate HTTP requests. to refresh the webpage, you can use
Window. location. reload (true );
 
Windowlocationhref usage

Missing & Symbol:
Here is an example:
<Script language = "javascript">
Zookeeper Doc ument. location. href = "./admin_index.asp? UserName = "& request (" patientname ") &" & patientnumber = "& request (" patientnumber "); </script>
Take a closer look:
It should be:
Window. location. href = "B. asp? Dr = "+ a +" & drr = "+ c;
