[英]Progress bar is not working properly
我正在嘗試創建進度條,以使用Javascript將文件上傳到AWS服務(lambda,S3),並且前端正在用materializecss完成。 但是,進度條移動得太快,並且在上傳之前到達終點,我可以看到使用innerHTML上傳文件的百分比。 所以,我確定它正在上傳。下面是我嘗試過的代碼:
<style>
#progressdisplay {
width: 100%;
background-color: #229954;
border-radius: 4px;
text-align: center;
line-height: 12px;
color: white;
}
#myBar {
height: 12px;
background-color: grey;
border-radius: 4px;
}
</style>
<div class="row">
<div class="file-field input-field col s12">
<div class="btn blue">
<span>Course File</span>
<input id="crsfile" type="file">
</div>
<div class="file-path-wrapper">
<input class="file-path validate" type="text" placeholder="Select the file">
</div>
</div>
</div>
<br/>
<div class="container" id="progressbar">
<div id="myBar">
<div id="progressdisplay"></div>
</div>
</div>
<br/>
<div class="container center">
<button class="btn waves-effect waves-light blue" type="submit" name="action" onclick="combinedfunctions()">Send
<i class="material-icons right">send</i>
</button>
</div>
<script>
request.on('httpUploadProgress', function(progress) {
var percentage = document.getElementById("progressdisplay");
percentage.innerHTML = (progress.loaded * 100) / progress.total + "%";
//console.log(progress.loaded + " of " + progress.total + " bytes");
function move() {
var width = 10;
var id = setInterval(frame, 10);
function frame() {
if (width >= 100) {
clearInterval(id);
} else {
width++;
this.$$("progressdisplay").style.width = percentage + '%';
this.$$("progressdisplay").innerHTML = percentage * 1 + '%';
}
}
}
});
</script>
這段代碼更有意義
request.on('httpUploadProgress', function(progress) {
var element = document.getElementById("progressdisplay");
var percentage = (progress.loaded * 100) / progress.total + "%";
element.innerHTML = percentage;
progressdisplay.style.width = percentage;
});
