在HTML和CSS中添加個人資料圖片

Question

我正在創建一個我需要的圖片用戶的個人資料圖片，我希望圖片爲圓形或矩形形式，默認情況下，圖像區域爲黑色或虛擬圖片，當用戶點擊該區域時，允許他/她選擇圖像。例如Facebook，Twitter上的Profile Picture Uploader。

你可以做的是隱藏輸入，只是行爲，就好像它被點擊點擊簡介圖像時：

$("#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

你也可以給用戶上傳的圖片的預覽：

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); 
}); 

效率注：可以使其更有效率，如果你使用createObjectURL不是讀取數據的URL。

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

正如你可以看到這裏MDN的URL.createObjectUrl將剛生成的文件，而不必把它加載到DOM，這絕對是最好大型文件的URL。

圓形圖像裁剪

顯示圖像裁剪成一個圈，你需要給它一個外div和應用border-radius它：

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

這個片段將所有三個步驟一起：

$("#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>

插入圖像的默認圖像分別標籤然後讀取URL而經由輸入標籤選擇圖像。

<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 ] 
 
    });

$("#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 {
