问题描述
我正在使用input type =file,现在我的要求是我只想选择png图片,也就是当我选择浏览一个png过滤器时应该应用。
我引用了 www.w3schools.com/tags/att_input_accept.asp
及以下代码是我正在使用的代码,这对Chrome非常适用,但不会使用Firefox和IE浏览器。
请任何人都可以帮助我了解我必须做什么错误?
<$ p $下面使用accept =image / *< / h2>
< input type =filename =pic1accept =image / */>
< h2>以下我只需接受png< / h2>
< input type =filename =pic1accept =image / png/>

您需要通过Java脚本验证它。下面是Java脚本验证的代码:
$ p $ function CheckFileName(){
var fileName = document.getElementById(uploadFile ).value
if(fileName ==){
alert(Browse to upload a valid File with png extension);
返回false;
}
else if(fileName.split(。)[1] .toUpperCase()==PNG)
return true;
else {
alert(File with+ fileName.split(。)[1] +无效,用png扩展名上传一个有效文件);
返回false;
}
返回true;
}
I am using input type="file", Now my requirement is that I only want to select png images, that is when I select browse a "png" filter should be applied.
I have referred www.w3schools.com/tags/att_input_accept.asp
and below is the code I am using, this works fine with Chrome but does not work with Firefox and IE.
Please can anyone help me understand what wrong I must be doing ?
<h2>Below uses accept="image/*"</h2>
<input type="file" name="pic1" accept="image/*" />
<h2>Below I need to accept only for png</h2>
<input type="file" name="pic1" accept="image/png" />
Here is a fiddle link to it http://jsfiddle.net/Jcgja/2/
You need to validate it through java script. Below is the code for java script validation
function CheckFileName() {
var fileName = document.getElementById("uploadFile").value
if (fileName == "") {
alert("Browse to upload a valid File with png extension");
return false;
}
else if (fileName.split(".")[1].toUpperCase() == "PNG")
return true;
else {
alert("File with " + fileName.split(".")[1] + " is invalid. Upload a validfile with png extensions");
return false;
}
return true;
}
