在 HTML 和 CSS 中的表单中添加头像

Question

我正在创建一个表单，其中我需要用户的个人资料图片，并且我希望图片是圆形或长方形。默认情况下，图像区域应为黑色或虚拟图片。当用户点击该区域时，he/she 被允许 select 一张图片，就像在 Facebook 或 Twitter 中上传个人资料图片一样。

我的表格

HTML

<div class="signup-w3ls">

Answer 1

你可以做的是隐藏输入并且当点击个人资料图片时就像它被点击一样：

$("#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>

图片预览

您还可以为用户提供上传图片的预览：

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 );
});

效率说明：如果使用createObjectURL而不是像URL.

那样读取数据，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 中看到的那样，URL.createObjectUrl 只会为文件生成 URL，而不必将其加载到 DOM，这绝对更适合大文件。

圆形图像裁剪

要显示裁剪成圆形的图像，您需要给它一个外部 div 并对其应用 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%;
}

完整的解决方案

此代码段将所有三个步骤放在一起：

$("#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

将图片标签与默认图片分开插入，然后在通过输入标签选择图片时读取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 ]
    });

Answer 3

$("#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 4

您可以使用下面的代码来应用这个图片选择器

<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>
