jquery - Retrieving value from wordpress database in javascript -

So I have created a table in my database named Inspiration ID and Travel card INT. And added the line with ID = 1 and Visit_Count = 2.

I am trying to retrieve the value in the Visit_Count in WordPress and only display values ​​in the warning for the test.

Ive been following the code code code and this example was used

    
 So I made my code  
  var $ inspirationWall_Count = 0; $ Inspiration Wall_Count = $ wpdb-> Get_var ($ wpdb- & gt; ready ("SELECT $ wpdb-> inspiration from WHOLE id = 1;););); Warning ($ inspirationWall_Count);   
 This value is not retrieved and saves it to $ Inspiration Wall_Count.  
 What am I doing?  
 Thank you   
 
 
 You can do this with a PHP with PHP Can not create a warning,  
 You will be redirected to  var $ inspiration valcount = 0;  is not required to define because it does not work with PHP,  
 So here's what you have to do,    $ Inspiration Wall_Count = 0 ; $ Inspiration Wall_Count = $ wpdb-> Get_var ($ wpdb- & gt; ready ("SELECT $ wpdb-> inspiration from WHOLE id = 1;););); Echo '& lt; Script & gt; Alert ('. $ Inspiration walcount.') & Lt; / Script & gt; ';
