The value obtained by js-JS is posted to the PHP code.

jsphphtml

<code> <script>var images = document.getElementsByClassName("c1");var imageStr = "";for(var i=0;i<images.length;i++){   imageStr+=images[i].src+'_';}alert(imageStr);</script></code>

Run the above js after clicking the submit button, and then post the imageStr array to 1.php without returning

Quoting jquery’s ajax

<code> $("#id").click(function(){
           var imageStr；//你要发送的参数
            $.ajax({
                type:"POST",
                url:"1.PHP",
                data:{
                    IMGSTR:imageStr
                },
                dataType:'json',
                success:function(json){
                   //回调函数

                }

            });
 })

. Use ajax to transfer values, such as $.post (page, JSON format data, callback function);

This must be using ajax. There are many examples on the Internet and it will be fine
