I'm using Asp.net MVC 4 and Bootstrap 3 to upload the image and replace the image with the previous one on modal. So far upload is working but image is not replacing, even if I reload the page and open the modal it still shows the old image which is on cache probably.
Here are my codes.
View that opens Modal
<script>
$('.btnInfo').click(function (e) {
var id = $(this).attr('href');
e.preventDefault();
$('#modal-content').load("FlatImageOne?FlId=" + id);
});
</script>
<a href="@Model.serial" class="btnInfo" data-target="#myModal" data-toggle="modal">Change Featured Image</a>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">Change Image</h4>
</div>
<div class="modal-body">
<div id="modal-content"></div>
</div>
</div>
</div>
</div>
View of the Modal
<script>
$(document).ready(function () {
$('#btnUpload').click(function (e) {
e.preventDefault();
var getFile = document.getElementById('file').files[0];
var getId = $("#getFlId").val();
var formdata = new FormData();
formdata.append("file", getFile);
formdata.append("getFlId", getId);
$.ajax({
url: '@Url.Action("FlatImageOne", "Home")',
type: 'POST',
data: formdata,
processData: false,
contentType: false,
success: function (data) {
alert("Upload successful!");
$('#imgOne').empty();
$('#imgOne').html('<img src="/Images/Flats/' + getId + '-0.png" alt="your image" class="img-responsive" />');
},
error: function () {
alert("Error! Please Try Again!");
}
});
});
});
</script>
<div>
@using (Html.BeginForm("FlatImageOne", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.ValidationSummary(true, "Error! Please provide valid information!")
<input type="file" name="file" id="file" style="width: 100%;" /><br />
<input type="hidden" name="getFlId" id="getFlId" value="@ViewBag.ImgName" />
<input id="btnUpload" type="submit" class="btn btn-info" value="Upload" />
}
</div><br />
<div id="imgOne">
<img src="~/Images/Flats/@(ViewBag.ImgName)-0.png" alt="your image" class="img-responsive" />
</div>
How can I remove the image from cache and update the uploaded image in the modal?
Add a query string
to your image source like this. This will prevent browser to cache
$('#imgOne').html('<img src="/Images/Flats/' + getId + '-0.png?' + (new Date()).getTime() + '" alt="your image" class="img-responsive" />');
