方式一：直接透明隐藏
.file_button_container,.file_button_container input {background: transparent url(./img/BT5AB.png) left top no-repeat;height: 47px;width: 263px;} .file_button_container {background: transparent url(./img/BT5AB.png) left top no-repeat;} .file_button_container input {opacity: 0;} 方式二：覆盖隐藏 js调用
.styled-button { background-color:#25A6E1;color:#fff;font-family:'Helvetica Neue',sans-serif; font-size:14px; line-height:30px;border-radius:20px;-webkit-border-radius:20px; -moz-border-radius:20px;border:0;width:120px;height:32px } function chooseFile() { $("#fileInput").click(); }
