在 HTML 和 CSS 的表單中添加個人資料圖片

Question

我正在創建一個表單，在該表單中我需要用戶的個人資料圖片，並且我希望圖片是圓形或矩形的。 默認情況下，圖像區域應為黑色或虛擬圖片。 當用戶點擊該區域時，他/她可以選擇一個圖像，就像在 Facebook 或 Twitter 上上傳的個人資料圖片一樣。

我的表格

HTML

Answer 1

您可以做的是隱藏輸入，就像單擊個人資料圖像時單擊它一樣：

 $("#profileImage").click(function(e) { $("#imageUpload").click(); });

 #imageUpload { display: none; } #profileImage { cursor: pointer; }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <image id="profileImage" src="http://lorempixel.com/100/100" /> <input id="imageUpload" type="file" name="profile_photo" placeholder="Photo" required="" capture>

圖片預覽

您還可以向用戶提供上傳圖像的預覽：

function previewProfileImage( uploader ) {   
    //ensure a file was selected 
    if (uploader.files && uploader.files[0]) {
        var imageFile = uploader.files[0];
        var reader = new FileReader();    
        reader.onload = function (e) {
            //set the image data as source
            $('#profileImage').attr('src', e.target.result);
        }    
        reader.readAsDataURL( imageFile );
    }
}

$("#imageUpload").change(function(){
    previewProfileImage( this );
});

效率說明：如果使用createObjectURL而不是將數據作為 URL 讀取，則可以提高效率。

function fasterPreview( uploader ) {
    if ( uploader.files && uploader.files[0] ){
          $('#profileImage').attr('src', 
             window.URL.createObjectURL(uploader.files[0]) );
    }
}

正如您在MDN 中看到的， URL.createObjectUrl只會生成文件的 URL，而不必將其加載到 DOM 中，這對於大文件來說絕對是可取的。

圓形圖像裁剪

要顯示裁剪成圓形的圖像，您需要給它一個外部div並對其應用border-radius ：

HTML：

<div id="profile-container">
   <image id="profileImage" src="aDefaultImage.png" />
</div>

CSS：

#profile-container {
    width: 150px;
    height: 150px;
    overflow: hidden;
    -webkit-border-radius: 50%;
    -moz-border-radius: 50%;
    -ms-border-radius: 50%;
    -o-border-radius: 50%;
    border-radius: 50%;
}

完整的解決方案

此代碼段將所有三個步驟放在一起：

 $("#profileImage").click(function(e) { $("#imageUpload").click(); }); function fasterPreview( uploader ) { if ( uploader.files && uploader.files[0] ){ $('#profileImage').attr('src', window.URL.createObjectURL(uploader.files[0]) ); } } $("#imageUpload").change(function(){ fasterPreview( this ); });

 #imageUpload { display: none; } #profileImage { cursor: pointer; } #profile-container { width: 150px; height: 150px; overflow: hidden; -webkit-border-radius: 50%; -moz-border-radius: 50%; -ms-border-radius: 50%; -o-border-radius: 50%; border-radius: 50%; } #profile-container img { width: 150px; height: 150px; }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="profile-container"> <image id="profileImage" src="http://lorempixel.com/100/100" /> </div> <input id="imageUpload" type="file" name="profile_photo" placeholder="Photo" required="" capture>

Answer 2

 $("#profileImage").click(function(e) { $("#imageUpload").click(); }); function fasterPreview( uploader ) { if ( uploader.files && uploader.files[0] ){ $('#profileImage').attr('src', window.URL.createObjectURL(uploader.files[0]) ); } } $("#imageUpload").change(function(){ fasterPreview( this ); });

 #imageUpload { display: none; } #profileImage { cursor: pointer; } #profile-container { width: 150px; height: 150px; overflow: hidden; -webkit-border-radius: 50%; -moz-border-radius: 50%; -ms-border-radius: 50%; -o-border-radius: 50%; border-radius: 50%; } #profile-container img { width: 150px; height: 150px; }

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="profile-container"> <image id="profileImage" src="http://lorempixel.com/100/100" /> </div> <input id="imageUpload" type="file" name="profile_photo" placeholder="Photo" required="" capture>

Answer 3

將圖像標簽與默認圖像分開插入，然后在通過輸入標簽選擇圖像的同時讀取 URL。

<img id="profile" src="default.png" alt="profile-image" />

 function readURL(input) { if (input.files && input.files[0]) { var reader = new FileReader(); reader.onload = function (e) { $('#profile').attr('src', e.target.result); } reader.readAsDataURL(input.files[0]); } } $("#image").change(function(){ readURL(this); //other uploading proccess [server side by ajax and form-data ] });

您可以使用以下代碼應用此圖片選擇器

<img id="idcardfront" src="images/UploadImgPlaceholder.png" data-type="editable" />
<script>
$("#idcardfront").each(function (i, e) {
var _inputFile = $('<input/>')
.attr('type', 'file')
.attr('hidden', 'hidden')
.attr('id', 'idCardFrontFile')
.attr('onchange', 'readImage()')
.attr('data-image-placeholder', e.id)
.attr('Class', 'hidden');
 $(e.parentElement).append(_inputFile);
 $(e).on("click", _inputFile, triggerClick);
 });
</script>
