如何在javascript中的函数内使用具有类名的变量？

Question

I have a variable x which counts the number of fields added to a form dynamically. I want to remove a field for which I tried to use the following code. But I can't.

$(wrapper).on("click",".remove_field", function(e){ //user click on remove text
        e.preventDefault(); $( "div" ).remove( ".org-details\'+(x-1)+\'" );x--;
    })
});

I want the output be something like this on runtime.

$( "div" ).remove( ".org-details1" );

Please help.

您应该使用模板文字（注意反引号）：

$("div").remove(`.org-details${x-1}`)
