我希望span標記在用戶單擊時被視為placeholder向上移動的位置，input form
如果我單擊表單右側，它可以作業，但是當我單擊文本時它不起作用

uj5u.com熱心網友回復：
添加一個onclickJS 事件，將焦點更改為輸入元素：
document.getElementById("your_input").focus()
您必須為您的輸入欄位提供一個 id，并為跨度提供一個。
document.getElementById("placeholder").addEventListener("click", function() {
document.getElementById("mail").focus();
