将图像居中 javascript
Centring an image in javascript
我是 JavaScript 的新手。正如您在下面看到的,在重定向之前显示了一个 gif 文件,但问题是 loading.gif 显示在上传框 div 之外。我怎样才能把它放在 div 内并居中(自动边距)。
我试了很多方法还是不行!
这里是JS函数:
//Disabling autoDiscover
Dropzone.autoDiscover = false;
$(function() {
//Dropzone class
var myDropzone = new Dropzone(".dropzone");
myDropzone.on("queuecomplete", function() {
// Display "Please Wait" gif
var myImage = new Image();
var ImgSrc = "./loading.gif";
myImage.setAttribute("src", ImgSrc);
myImage.style.margin = "0 auto";
document.body.appendChild(myImage);
// Wait 3 seconds and then redirect to the link
window.setTimeout(function() {
location.href = 'http://www.i-0s.ir/site';
}, 3000);
});
});
这里是 HTML 部分:
<div class="upload-box">
<p>Please upload your files</p>
<div class="image_upload_div">
<form action="upload.php" class="dropzone"></form>
</div>
</dive>
试试这个:
$(function() {
//Dropzone class
var myDropzone = new Dropzone(".dropzone");
myDropzone.on("queuecomplete", function() {
// Display "Please Wait" gif
$('.upload-box').append('<div style="text-align:center;"><img src="./loading.gif"/></div>')
// Wait 3 seconds and then redirect to the link
window.setTimeout(function() {
location.href = 'http://www.i-0s.ir/site';
}, 3000);
});
});
