Question

i use recaptcha

Recaptcha.create("xxx", "recaptcha", {
            theme: 'clean',
            tabindex: 0,
            callback: $("#id").focus
        });

i want to use callback to focus some field, but it doesn’t work, only callback: f works

 function f() {
        $("#FIO").focus();
    }

what is the problem?

Answer 1

The callback needs to be a function. What you have attempts to execute the $() function and reference the focus method of it. That won’t work. Try this.

Recaptcha.create("xxx", "recaptcha", {
        theme: 'clean',
        tabindex: 0,
        callback: function() { $("#id").focus(); }
    });
