weui样式库weui.cssexample.css请前往https://github.com/weui/weui下载。记得是最新版本,不要下载错了.

本案例是基于微信weui的Uploader上传组件,现在我们来体验一番吧。使用方法如下:

一,引入css文件

<link rel="stylesheet" href="https://weui.io/weui.css">
<link rel="stylesheet" href="https://weui.io/example.css">

记得html设置成移动浏览

<meta name="viewport" content="width=device-width,initial-scale=1,user-scalable=0"

二、引用jquery的依赖库

由于上传组件的js依赖jquery,所以本案例需要引入jquery的依赖库,在这里我们引用的是网络地址

 <script src="http://libs.baidu.com/jquery/2.0.0/jquery.js"></script>

三、Uploader上传组件html代码

在<body></body>之间添加如下代码

<div class="page__hd">
        <h1 class="page__title">Uploader</h1>
        <p class="page__desc">上传组件,一般配合<a class="link" href="#gallery">组件Gallery</a>来使用。[www.vxzsk.com V型知识库原创]</p>
    </div>

	<div class="page__bd">
        <div class="weui-gallery" id="gallery">
            <span class="weui-gallery__img" id="galleryImg"></span>
            <div class="weui-gallery__opr">
                <a href="javascript:" class="weui-gallery__del">
                    <i class="weui-icon-delete weui-icon_gallery-delete"></i>
                </a>
            </div>
        </div>

        <div class="weui-cells weui-cells_form">
            <div class="weui-cell">
                <div class="weui-cell__bd">
                    <div class="weui-uploader">
                        <div class="weui-uploader__hd">
                            <p class="weui-uploader__title">图片上传</p>
                            <div class="weui-uploader__info">0/2</div>
                        </div>
                        <div class="weui-uploader__bd">
                            <ul class="weui-uploader__files" id="uploaderFiles">
                                <li class="weui-uploader__file" style="background-image:url(https://weui.io/images/pic_160.png)"></li>
                                <li class="weui-uploader__file" style="background-image:url(https://weui.io/images/pic_160.png)"></li>
                                <li class="weui-uploader__file" style="background-image:url(https://weui.io/images/pic_160.png)"></li>
                                <li class="weui-uploader__file weui-uploader__file_status" style="background-image:url(https://weui.io/i/images/pic_160.png)">
                                    <div class="weui-uploader__file-content">
                                        <i class="weui-icon-warn"></i>
                                    </div>
                                </li>
                                <li class="weui-uploader__file weui-uploader__file_status" style="background-image:url(https://weui.io/i/images/pic_160.png)">
                                    <div class="weui-uploader__file-content">50%</div>
                                </li>
                            </ul>
                            <div class="weui-uploader__input-box">
                                <input id="uploaderInput" class="weui-uploader__input" type="file" accept="image/*" multiple="">
                            </div>
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>

四、Uploader组件js代码

 <script type="text/javascript" class="uploader js_show">
    $(function(){
        var tmpl = '<li class="weui-uploader__file" style="background-image:url(#url#)"></li>',
            $gallery = $("#gallery"), $galleryImg = $("#galleryImg"),
            $uploaderInput = $("#uploaderInput"),
            $uploaderFiles = $("#uploaderFiles")
            ;

        $uploaderInput.on("change", function(e){
            var src, url = window.URL || window.webkitURL || window.mozURL, files = e.target.files;
            for (var i = 0, len = files.length; i < len; ++i) {
                var file = files[i];

                if (url) {
                    src = url.createObjectURL(file);
                } else {
                    src = e.target.result;
                }

                $uploaderFiles.append($(tmpl.replace('#url#', src)));
            }
        });
        $uploaderFiles.on("click", "li", function(){
            $galleryImg.attr("style", this.getAttribute("style"));
            $gallery.fadeIn(100);
        });
        $gallery.on("click", function(){
            $gallery.fadeOut(100);
        });
    });</script>

五、效果

准备好一张图片,本案例准备的一张二维码图片,点击添加,效果如下

点击页面中的“+”图案,会显示选择图片,然后我们选一张图片,效果如下

如上图所示,二维码就是我们要上传的图片。
