Também enfrentei um problema semelhante. Aqui estão os detalhes ao fazer o upload do logotipo usando a caixa suspensa de upload do logotipo
<div>
<div class="uploader greyLogoBox" id="uploader" flex="64" onclick="$('#filePhoto').click()">
<img id="imageBox" src="{{ $ctrl.companyLogoUrl }}" alt=""/>
<input type="file" name="userprofile_picture" id="filePhoto" ngf-select="$ctrl.createUploadLogoRequest()"/>
<md-icon ng-if="!$ctrl.isLogoPresent" class="upload-icon" md-font-set="material-icons">cloud_upload</md-icon>
<div ng-if="!$ctrl.isLogoPresent" class="text">Drag and drop a file here, or click to upload</div>
</div>
<script type="text/javascript">
var imageLoader = document.getElementById('filePhoto');
imageLoader.addEventListener('change', handleImage, false);
function handleImage(e) {
var reader = new FileReader();
reader.onload = function (event) {
$('.uploader img').attr('src',event.target.result);
}
reader.readAsDataURL(e.target.files[0]);
}
</script>
</div>
CSS.css
.uploader {
position:relative;
overflow:hidden;
height:100px;
max-width: 75%;
margin: auto;
text-align: center;
img{
max-width: 464px;
max-height: 100px;
z-index:1;
border:none;
}
.drag-drop-zone {
background: rgba(0, 0, 0, 0.04);
border: 1px solid rgba(0, 0, 0, 0.12);
padding: 32px;
}
}
.uploader img{
max-width: 464px;
max-height: 100px;
z-index:1;
border:none;
}
.greyLogoBox {
width: 100%;
background: #EBEBEB;
border: 1px solid #D7D7D7;
text-align: center;
height: 100px;
padding-top: 22px;
box-sizing: border-box;
}
#filePhoto{
position:absolute;
width:464px;
height:100px;
left:0;
top:0;
z-index:2;
opacity:0;
cursor:pointer;
}
antes da correção, meu código era:
function handleImage(e) {
var reader = new FileReader();
reader.onload = function (event) {
onclick="$('#filePhoto').click()"
$('.uploader img').attr('src',event.target.result);
}
reader.readAsDataURL(e.target.files[0]);
}
O erro no console:
Eu o resolvi removendo onclick="$('#filePhoto').click()"
da tag div.
data
do ajax. Corrigido o erro declarando as variáveis.
