有在HTML 5文件中工作的功能,但其在JavaScript 我必須將它更改爲jQuery函數轉換的JavaScript改變事件jQuery的
<style>
.thumb {
height: 75px;
border: 1px solid #000;
margin: 10px 5px 0 0;
}
</style>
<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) {
// Render thumbnail.
var span = document.createElement('span');
span.innerHTML = ['<img class="thumb" src="', e.target.result,
'" title="', escape(theFile.name), '"/>'].join('');
document.getElementById('list').insertBefore(span, null);
};
})(f);
// Read in the image file as a data URL.
reader.readAsDataURL(f);
}
}
document.getElementById('files').addEventListener('change', handleFileSelect, false);
</script>
這將創建一個從輸入圖像中翻滾當地 ,所以我需要改變這個jQuery中 工作是這樣的:
$('#thisfile').change(function(){
handleFileSelect(this)
});
但是當我運行jQuery函數顯示它TypeError: evt.target is undefined
錯誤 我能提供給日e jquery函數參數在這裏?
謝謝!這工作! –
