jQuery insertAfter doesn't work in some situations

Question

I want to add a hidden input after some element. I am using this code:

$("<input type="text">").insertAfter(".addProduct");

It doesn't work. But if I replace to it works.

$("<span>ddd</span>").insertAfter(".addProduct");

It works. Help me.

Thank you.

Answer 1

You should use single quotes:

$('<input type="text" />').insertAfter('.addProduct');

Answer 2

If you create this script in php, use this:

$("<input type=\"text\">").insertAfter(".addProduct");
