select默认不选中任何一项

Question

怎么能够让select不选中任何一项？现在默认都是选中第一项

Answer 1

原生並沒有提供預設選取空白選項，但是我們可自己加jsFiddle<select> &nbsp;&nbsp;&nbsp;&nbsp;<option&nbsp;disabled&nbsp;selected&nbsp;value></option> &nbsp;&nbsp;&nbsp;&nbsp;<option&nbsp;value="1">1</option> &nbsp;&nbsp;&nbsp;&nbsp;<option&nbsp;value="2">2</option> &nbsp;&nbsp;&nbsp;&nbsp;<option&nbsp;value="3">3</option> &nbsp;&nbsp;&nbsp;&nbsp;<option&nbsp;value="4">4</option></select>
