我希望删除的文本文件按其内容或完整位置显示,以便我可以将该位置的内容加载到“drop_zone”中.
这就是我现在所拥有的.我只能访问文件名：
<html>
<head>
<title></title>
</head>
<body>
<textarea id="drop_zone">Drop files here</textarea>
<output id="list"></output>
<script>
function handleFileSelect(evt) {
evt.stopPropagation();
evt.preventDefault();
var files = evt.dataTransfer.files; // FileList object.
document.getElementById('drop_zone').innerHTML = files[0].name;
}
function handleDragOver(evt) {
evt.stopPropagation();
evt.preventDefault();
evt.dataTransfer.dropEffect = 'copy'; // Explicitly show this is a copy.
}
// Setup the dnd listeners.
var dropZone = document.getElementById('drop_zone');
dropZone.addEventListener('dragover',handleDragOver,false);
dropZone.addEventListener('drop',handleFileSelect,false);
</script>
</body>
</html>
解决方法
这是最终的代码：
<html>
<head>
<title></title>
</head>
<body>
<textarea id="drop_zone">Drop files here</textarea>
<script>
function handleFileSelect(evt) {
evt.stopPropagation();
evt.preventDefault();
var files = evt.dataTransfer.files; // FileList object.
var reader = new FileReader();
reader.onload = function(event) {
document.getElementById('drop_zone').value = event.target.result;
}
reader.readAsText(files[0],"UTF-8");
}
function handleDragOver(evt) {
evt.stopPropagation();
evt.preventDefault();
evt.dataTransfer.dropEffect = 'copy'; // Explicitly show this is a copy.
}
// Setup the dnd listeners.
var dropZone = document.getElementById('drop_zone');
dropZone.addEventListener('dragover',false);
</script>
</body>
</html>
