Three solutions for uploading files on the Web Share with everyone:
What I want to use here is the form method. By setting the enctype="multipart/form-data" attribute for the form element, the data submitted by the form is submitted in binary encoding, and the content of the uploaded file can be obtained by using the binary stream to obtain the content in the Servlet that receives this request. This enables file upload.
The enctype attribute of the form element specifies the encoding method of the form data. This attribute has 3 values:
I found two ways on the Internet, PHP with apc and uploadprogress. What I want to use this time is uploadprogress. Click on the address to download the corresponding version of php. dll. Install the php_uploadprogress.dll extension and restart apache.
Principle of progress bar implementation:
Here we use an iframe method to upload files without refreshing.
The picture after the upload is completed:
<body>
<div style="padding:20px">
<form action="action.php" enctype="multipart/form-data" method="post" target="iframeUpload">
<iframe name="iframeUpload" width="400" height="400" frameborder='1'></iframe>
<input type="hidden" name="UPLOAD_IDENTIFIER" value="1" />
<input id="file1" name="file1" type="file"/>
<input value="上传" type="submit" onclick="startProgress()"/>
</form>
</div>
<div style="width: 500px; height: 20px;border:1px solid red">
<div style="position: relative; height: 20px; background-color: purple; width: 0%;" class="barinner"></div>
</div>
<div id='showNum'></div>
<div class="prbar">
<div class="prpos barinner"></div>
</div>
</body>
In the above HTML code, please pay attention to UPLOAD_IDENTIFIER. This is used to locate and view the upload progress of which file. I will write it as a 1 here, but you can write it as a random number generated by PHP. The following is the JS script:
var proNum=0;
var loop=0;
var progressResult = "";
var interval;
function sendURL() {
$.ajax({
type : 'GET',
url : "getprogress.php",
async : true,
cache : false,
dataType : 'json',
data: "progress_key=" + $('input[name=UPLOAD_IDENTIFIER]').val(),
success : function(e) {
proNum=parseInt(e);
if(e){
$('.barinner').css('width', proNum+"%");
$('#showNum').html(proNum+"%");
setTimeout("getProgress()", 200);
}else{
if(interval == 1){
$('.barinner').css('width', "100%");
$('#showNum').html("100%");
}
}
}
});
}
function getProgress(){
loop++;
sendURL();
}
function startProgress(){
interval = 1;
$('.barinner').css('width', proNum+"%");
$('#showNum').html(proNum+"%");
setTimeout("getProgress()", 500);
}
The following is the content of the getprogress.php file:
<?php
if (function_exists("uploadprogress_get_info")) {
$info = uploadprogress_get_info($_GET['progress_key']);
if(!empty($info)){
if(($info['bytes_uploaded'] < $info['bytes_total']) && !empty($info['bytes_uploaded']) && !empty($info['bytes_total'])){
$proNum = floor(($info['bytes_uploaded']/$info['bytes_total'])*100);
}else{
$proNum = 100;
}
echo $proNum;
}else{
echo 0;
}
}
After the upload is completed, I show the CSS of two progress bars, the second one is written with the latest CSS3. Some CSS3 animation properties are used.
