我需要从后端到前端获取数组$data，以便对其进行组织以供查看。我只能找到使用jQuery Ajax的例子。
<!DOCTYPE html>
<html>
<style>
.table_class{
display:none;
}
</style>
<script>
async function uploadFile() {
let formData = new FormData();
formData.append("file", fileupload.files[0]);
console.log(formData);
await fetch('file_ingest.php', {
method: "POST",
body: formData,
});
var test = document.getElementById("test");
test.innerText = ('The file has been uploaded successfully.');
//var returned_vals = JSON.parse(formData.responseText);
//console.log(returned_vals);
}
</script>
<body>
<input id="fileupload" type="file" name="fileupload" />
<button id="upload-button" onclick="uploadFile()"> Upload </button>
<p id = "test"></p>
</body>
</html>
我需要得到一个数组$data从后端到前端，以便组织它查看。我只能找到使用jQuery Ajax的例子。
<?php
set_time_limit(120);
/* Get the name of the uploaded file */
$filename = $_FILES['file']['name'];
/* Choose where to save the uploaded file */
$location = "uploads/".$filename;
if ( move_uploaded_file($_FILES['file']['tmp_name'], $location) ) {
echo 'Success';
} else {
echo 'Failure';
$CSVfp = fopen("uploads/${filename}", "r");
if($CSVfp !== FALSE) {
while(! feoF($CSVfp)) {
$data = fgetcsv ($CSVfp, 1000, ",");
print json_encode($data);
//echo $data;
}
}
fclose($CSVfp);
<?php
set_time_limit(120); // if you need this you may have other problems
/* Get the name of the uploaded file */
$filename = $_FILES['file']['name'];
/* Choose where to save the uploaded file */
$location = "uploads/".$filename;
$response = [];
/* Save the uploaded file to the local filesystem */
if ( move_uploaded_file($_FILES['file']['tmp_name'], $location) ) {
$response['status'] = 'Files Save Success';
// read the file here, if it failed the upload and move
// there is no point trying to read it
if (($fp = fopen($location, "r")) !== FALSE) {
while (($data = fgetcsv($fp, 1000, ",")) !== FALSE) {
$response['data'][] = $data
}
fclose($fp);
}
} else {
$response['status'] = 'File Save Failure';
}
// now you can return either an error or a success and data
echo json_encode($response);
现在您需要更改javascript以在正确的位置查找状态并从正确的位置卸载行数据
