PHP简单留言本的制作(四)

签写留言时头相头像选择的一段javascript代码:(很有用的哦)

function showimage(value)

{

if(value!= '') {

document.images.useravatars.src='images/'+value;

} else{

document.images.useravatars.src='images/none.gif';

}

}

对应的HTML语句的书写:

<select name="face" onChange='showimage(this.options[this.selectedIndex].value)'>

<option value="f01.gif" >boy1</option>

<option value="f02.gif">boy2</option>

<option value="f07.gif" selected>boy7</option>

</select>

<img name=useravatars src='images/f07.gif' height=100 width=100 border=0>
