为什么选择器不起作用？ JS

Question

I have a class name active and in js I have something like this

var selectClass = active;
var a = $("'." + selectCLass + "'");
a.on('click', function(){})

When I do this, it would keep on giving me errors.

What am I missing here?

Answer 1

生成的选择器字符串有错误...使其像

var a = $("." + selectCLass);
