JavaScript-embed PHP code in JS string, add to page is commented out

Need to take value from the background database, in the SELECT tag to traverse the data inside the database

  
       选择商品编号
   
                 
    
         
   
     

The default select tag has only one

Click the plus sign below to add a row of data

the problem comes!!! Here we use the JS code to define a string , and then use the append of JQ to add to the node , generate a data table, but this time the select tag how to traverse the database , the PHP code written into the JS string inside, added to the page after the comment out , does not work.

So what's the best way to solve this?!!

Here's what I wrote:

Your writing is too magical, JS and do not know PHP tags, of course, can not ...

Of course, if you put the code directly in the PHP file, with the script tag is also possible, but definitely not put in the JS file ...

The ideal way to do this is to use PHP to output the data in JSON format, and then JS parse the JSON, splicing code
