您可以按照以下方式使用JavaScript
you can use javascript as per below
<script language="javascript">
var imgRe = /^.+\.(jpg|jpeg|gif|png)
/i; 函数showImage(obj) { var path = obj.value; 如果(path.search(imgRe)！= -1) { document ['image'].src ='file://'+ path; } 别的 { alert(仅限JPG，PNG和GIF！")； } } < /script > < html > < 输入 =" span> 名称 =" span> 大小 =" span> onchange =" / > < br > < img =" 图片" > < /html >
/i; function showImage(obj) { var path = obj.value; if (path.search(imgRe) != -1) { document['image'].src = 'file://'+path; } else { alert("JPG, PNG, and GIFs only!"); } } </script> <html> <input type="file" name="myImage" size="30" onchange="showImage(this)"/><br> <img name="image"/> </html>
