我正在尝试从多个输入文件中获取所有url值。它仅适用于一个图像,但是如果我尝试附加多个图像,则会检索到空响应,并且只能正确获取最后一个图像。希望任何人都可以帮助解决这个问题! 在下面和JSFiddle示例中发布我的代码:
<input type="file" id="files" name="files[]" multiple />
<output id="list"></output>
<script>
function handleFileSelect(evt) {
var files = evt.target.files; // FileList object
// Loop through the FileList and render image files as thumbnails.
for (var i = 0, f; f = files[i]; i++) {
// Only process image files.
if (!f.type.match('image.*')) {
continue;
}
var reader = new FileReader();
// Closure to capture the file information.
reader.onload = (function(theFile) {
return function(e) {
//show url image
var dataURL = reader.result;
alert(dataURL);
};
})(f);
// Read in the image file as a data URL.
reader.readAsDataURL(f);
}
}
document.getElementById('files').addEventListener('change', handleFileSelect, false);
</script>
