Javascript-從文件夾獲取圖像

[英]Javascript - get images from a folder

問題描述

我需要加載獲取圖像並在我在頁面上使用的js證明插件中使用它們。 這是我的腳本： 

$(document).ready(function(){

  var folder = "img/people";

  $.ajax({
    url : folder,
    success: function (data) {
        console.log(data);
    }
  });

});
var showPhotos = function(photos){

    $('.image-container').empty().justifiedImages({
        images : photos,
        rowHeight: 500,
        maxRowHeight: $('.gallery').height(),
        thumbnailPath: function(photo, width, height){
            var purl = photo.url_s;
            if( photo.url_n && (width > photo.width_s * 1.2 || height > photo.height_s * 1.2) ) purl = photo.url_n;
            if( photo.url_m && (width > photo.width_n * 1.2 || height > photo.height_n * 1.2) ) purl = photo.url_m;
            if( photo.url_z && (width > photo.width_m * 1.2 || height > photo.height_m * 1.2) ) purl = photo.url_z;
            if( photo.url_l && (width > photo.width_z * 1.2 || height > photo.height_z * 1.2) ) purl = photo.url_l;
            return purl;
        },
        getSize: function(photo){
            return {width: photo.width_s, height: photo.height_s};
        },
        margin: 1
    });
}

但是，當我執行console.log（data）時，我得到以下信息：

如何從文件夾中獲取圖像，然后在此插件中使用它們？

1 個解決方案

@leff由於瀏覽器的安全框架，我們無法獲取文件的位置。 您將獲得文件路徑為“ C：\\ fakepath \\ Capture.PNG”。 因此，要解決該問題。 我找到了一種解決方案，可能是這一項工作。

因此，您可以做一個簡單的技巧，將一個變量並為其分配文件位置的基址。 之后，在文件名后附加基址，這將為您提供文件位置。

希望這個能解決你的問題
