推荐答案

您可以使用以下内容：

You can use the following:

<input type="text" style="color:#ccc;" value="username" onfocus="this.value = this.value=='username' ? '' : this.value; this.style.color='#000';" onfocusout="this.value = this.value == '' ? this.value = 'username' : this.value; this.value=='username' ? this.style.color='#ccc' : this.style.color='#000'"/>

<input type="text" style="color:#ccc;" value="password" onfocus="this.value = this.value=='password' ? '' : this.value; this.style.color='#000';" onfocusout="this.value = this.value == '' ? this.value = 'password' : this.value; this.value=='password' ? this.style.color='#ccc' : this.style.color='#000'"/>
