Ajax pass parameters, PHP can't get the solution

Ajax pass parameters, PHP cannot get
The AJAX code is as follows:

JScript Code

  
   Type: ' POST ', url: '. /php/a.php?id= ' + ' abc ', Success:function (data) {    alert (data);}

The PHP code is as follows:

PHP Code

  
   echo $_get[' ID '];

Why does the JS file pop up the "ABC" dialog box, and the PHP page has nothing to do with it?

------Solution--------------------

Ajax.html

HTML Code

Landlord sure you can run PHP?
------Solution--------------------
Otherwise, the landlord tries to add a random number to the get parameter, and is not cached by the browser.
------Solution--------------------
Oh, it's the get parameter on the post, not the caching problem.

Even more oddly, if a.php is using Var_dump ($_get[' ID "), then a pre tag will appear in the JS popup dialog, with the ID value in the pre tag.

It is estimated that the Internet Explorer cache problem, after modifying the JS code, to clear the browser cache

Are you sure the parameters have been put through when you jump to the PHP page?
