我们实际上如何创建一个变量,该变量是文件在sweetalert上的上传百分比?我使用PyCharm作为平台,使用Django作为GUI框架。
我实际上已经看过几种与Ajax,PHP和sweetalert有关的问题(找不到与我的问题有关的特定问题),并尝试将其中一些解决方案混合使用,但不幸的是,没有一个他们中的人。
下面是我的当前代码:
在 html 中:
<form id='upload' method="post" enctype="multipart/form-data" onsubmit="myFunction()"> {% csrf_token %}
<input name="datas" type="file" id="datas"/>
<input type="submit" value="Submit" name="btnform3" style="height:6%; width:75%"/>
</form>
<script>
function myFunction() {
Swal.fire({
title: 'Status:',
text: 'Files Uploading...',
imageUrl:'static/widget-loader-lg-en.gif',
html: '<h3 id="status"></h3>',
showConfirmButton: false,
allowOutsideClick: false,
})
}
function _(el) {
return document.getElementById(el);
}
function uploadFile() {
var file = _("datas").files[0];
var formdata = new FormData();
formdata.append("datas", file);
var ajax = new XMLHttpRequest();
ajax.upload.addEventListener("progress", progressHandler, false);
ajax.addEventListener("load", completeHandler, false);
ajax.open("POST","static/upload.php");
ajax.send(formdata);
}
function progressHandler(event) {
var percent = (event.loaded / event.total) * 100;
_("status").innerHTML = Math.round(percent) + "% uploaded... please wait";
}
function completeHandler(event) {
_("status").innerHTML = event.target.responseText;
}
在 upload.php 中:
<?php
$fileName = $_FILES["datas"]["name"]; // The file name
$fileTmpLoc = $_FILES["datas"]["tmp_name"]; // File in the PHP tmp folder
$fileType = $_FILES["datas"]["type"]; // The type of file it is
$fileSize = $_FILES["datas"]["size"]; // File size in bytes
$fileErrorMsg = $_FILES["datas"]["error"]; // 0 for false... and 1 for true
?>
任何评论和解决方案将不胜感激。谢谢。
答案 0 :(得分:1)
万一有人想知道答案,那就是-删除myFunction()并添加到uploadFile()
function uploadFile() {
var file = _("raw_mica_datas").files[0];
var formdata = new FormData();
formdata.append("raw_mica_datas", file);
var ajax = new XMLHttpRequest();
ajax.upload.addEventListener("progress", progressHandler, false);
ajax.open("POST","static/upload.php");
ajax.send(formdata);
swal.fire({
title: 'Status:',
text: 'Files Uploading...',
html: '<h3 id="status">',
imageUrl:'static/InternetSlowdown_Day.gif',
showConfirmButton: false,
allowOutsideClick: false,
})
}
干杯:)
