javascript - js传递上传图片路径有点问题请教？

Question

    uploader.on('uploadSuccess', function(file,response) {        //uploader.options.formData.data_type = 1;        //alert(JSON.stringify(response.status));//response是返回的json串 status是json中的元素        $("#imgs_url").append(JSON.stringify(response.imgurl)+"</br>");//上传后返回的图片路径追加到div中去        var addtype3=$("#info3").val(JSON.stringify(response.imgurl));    });

这是一段上传多个图片的js文件，全文在下面，我在上传页面用 <input type="text" class="form-control" id="info3" name='imgs_url1' />可以得到一张图片存放的地址，
问题是我上传2张图片的，他只得到最后一张的地址，我想要2张的地址，怎么改？

用<div id="imgs_url"></div>可以在上传页显示2张图片的地址
我再添加一个input框行不行，怎么改下？

你那样会覆盖，你可以每次上传之后追加到数组里，然后赋值给#info3，info3就会有所有你上传图片地址

var imgUrls = [];uploader.on('uploadSuccess', function(file,response) {    $("#imgs_url").append(JSON.stringify(response.imgurl)+"</br>");     imgUrls.push(JSON.stringify(response.imgurl));    $("#info3").val(imgUrls.join(', '));});
