扔个三星炸死你 · Answer

I don’t know what you mean by appending? What I understand is that originally val was an empty string'', I clicked on 'Hydration,', and then the strings were concatenated, val became 'Hydrating,', then I clicked on 'Moisturizing,' and appended var It becomes 'hydrating, moisturizing,'

怪我咯 · Answer

$(".func span").click(function(){
    var text = $(this).text();
    var $input = $(".box input")
    $input.val($input.val()+text);
});

Everything mentioned above is correct. You may not understand the difference between append and direct assignment to val(). Append inserts an element into an existing dom node, such as:

1. 把补水,  插入到p中
var span = '补水,';
$("p").append(span),此时span就被加入到p中了
2. 而赋值直接是在input中给定一个值
直接
$("input").val(你需要插入的值)
