    height: 20px;
    width: 20px;
}

js代码

function check_object_like_radio(cb) {
    for (j = 0; j < 8; j++) {
        if (eval("document.checkbox_redio.checkbox_content[" + j + "].checked") == true) {
            document.checkbox_redio.checkbox_content[j].checked = false;
            if (j == cb) {
                document.checkbox_redio.checkbox_content[j].checked = true;
            }
        }
    }
