我希望发生的是当用户从HTML页面上传CSV时该文件应保存到我提供的本地目录。
如果文件已经存在则应该覆盖两件事情中的一件,否则它应该创建一个新文件。
以下是我的代码:
<!DOCTYPE html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-alpha1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-csv/0.71/jquery.csv-0.71.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
// The event listener for the file upload
document.getElementById('txtFileUpload').addEventListener('change', upload, false);
// Method that checks that the browser supports the HTML5 File API
function browserSupportFileUpload() {
var isCompatible = false;
if (window.File && window.FileReader && window.FileList && window.Blob) {
isCompatible = true;
}
return isCompatible;
}
// Method that reads and processes the selected file
function upload(evt) {
if (!browserSupportFileUpload()) {
alert('The File APIs are not fully supported in this browser!');
} else {
var data = null;
var file = evt.target.files[0];
var reader = new FileReader();
reader.readAsText(file);
reader.onload = function(event) {
var csvData = event.target.result;
data = $.csv.toArrays(csvData);
if (data && data.length > 0) {
alert('Imported -' + data.length + '- rows successfully!');
} else {
alert('No data to import!');
}
};
reader.onerror = function() {
alert('Unable to read ' + file.fileName);
};
}
}
});
</script>
</head>
<body>
<div id="dvImportSegments" class="fileupload ">
<fieldset>
<legend>Upload your CSV File</legend>
<input type="file" name="File Upload" id="txtFileUpload" accept=".csv" />
</fieldset>
</div>
<script>
document.getElementById("data").innerHTML;
</script>
</body>
</html>

您需要一个公开此html文件的服务器(PHP或NodeJS)(通常放在公共文件夹中),然后提供此html文件,然后您可以通过服务器进行验证和存储。您可以稍后添加数据库挂钩,但这取决于您的需求以及您要上传的数据量。
