使用 jQuery 显示文本文件中的数据 [英] Display data from text file with jQuery

问题描述

我需要显示/附加来自文件 file.txt 的数据，该文件包含 400 行，格式如下:

http://www.exemple.com/img1.jpg,title1,subtitle1,description1;http://www.exemple.com/img2.jpg、title2、subtitle2、description2；http://www.exemple.com/img3.jpg、title3、subtitle3、description3；http://www.exemple.com/img4.jpg、title4、subtitle4、description4；http://www.exemple.com/img5.jpg，title5，subtitle5，description5；

我知道如何将 1 行附加到

.但是，这里每行有 4 个元素.我需要把它们变成 4 个元素，我可以用来显示它们.

我正在使用这个 jQuery 片段，它适用于每行 1 个元素并在行尾拆分.

$.get('file.txt', function(data) {//var fileDom = $(data);var lines = data.split("\n");$.each(lines, function(n, elem) {$('#display').append('<div><img src="' + elem + '"/></div>');});});

HTML 输出将是:

$('#display').append('<div class="container"><div class="left"><img src="' + src + '"/></div><div class="right">'+title+'<br/>'+副标题+'<br/>'+描述+'</div><;/div>');

感谢您的见解！

解决方案

你的错误在于你拆分的方式...

你需要做这样的事情，(.when(file) 应该替换为 .get('file.txt'):

var file = "http://www.exemple.com/img1.jpg, title1, subtitle1, description1; http://www.exemple.com/img2.jpg、title2、subtitle2、description2；http://www.exemple.com/img3.jpg、title3、subtitle3、description3；http://www.exemple.com/img4.jpg、title4,subtitle4,description4;http://www.exemple.com/img5.jpg,title5,subtitle5,description5;";函数 AppendImagesCtrl($) {$//.get('file.txt').when(file)//这是一个假的.then(file => file.split(/; ?\n? ?/)).then(lines =>lines.map((line, i) => {line = line.trim();如果(！行){ 返回"；}让 [img，标题，副标题，描述] = line.split(/, ?n? ?/);返回 `<article id="${(i + 1)}"><h1>${title}</h1><img src="${img}" alt="${img}"/></文章>`;})).then(view => $('#example').append(view));}window.jQuery(document).ready(AppendImagesCtrl);

img { width: 100px;高度:50px；背景:青色；}文章 { 填充:5px 10px;背景:浅海绿；底边距:5px;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><div id="example"></div>

I need to display/append the data from a file, file.txt, containing 400 lines which are in the following format:

http://www.exemple.com/img1.jpg, title1, subtitle1, description1;
http://www.exemple.com/img2.jpg, title2, subtitle2, description2;
http://www.exemple.com/img3.jpg, title3, subtitle3, description3;
http://www.exemple.com/img4.jpg, title4, subtitle4, description4;
http://www.exemple.com/img5.jpg, title5, subtitle5, description5;

I know how to append 1 line into a <div>. But, here we have 4 elements on each line. I need to turn them into 4 elements that I could use to display them.

I am using this jQuery snippet that works fine for each line with 1 element and splits at the end of the line.

$.get('file.txt', function(data) {
  //var fileDom = $(data);

  var lines = data.split("\n");

  $.each(lines, function(n, elem) {
    $('#display').append('<div><img src="' + elem + '"/></div>');
  });
});

The HTML output would be:

$('#display').append('<div class="container"><div class="left"><img src="' + src + '"/></div><div class="right">' + title + '<br/>' + subtitle + '<br/>' + description + '</div></div>');

Thanks for insights!

Your error resides on the way you split...

You need to do something like that, (.when(file) should be replaced with .get('file.txt'):

var file = "http://www.exemple.com/img1.jpg, title1, subtitle1, description1; http://www.exemple.com/img2.jpg, title2, subtitle2, description2; http://www.exemple.com/img3.jpg, title3, subtitle3, description3; http://www.exemple.com/img4.jpg, title4, subtitle4, description4; http://www.exemple.com/img5.jpg, title5, subtitle5, description5;";

function AppendImagesCtrl($) {
  $
//  .get('file.txt')
  .when(file) // this is a fake
  .then(file => file.split(/; ?\n? ?/))
  .then(lines => lines.map((line, i) => {
    line = line.trim();
    if(!line) { return ""; }
    
    let [
      img, title, subtitle, description
    ] = line.split(/, ?n? ?/);
    
    return `<article id="${(i + 1)}">
<h1>${title}</h1>
<img src="${img}" alt="${img}" />
</article>`;
  }))
  .then(view => $('#example').append(view))
  ;  
}

window.jQuery(document).ready(AppendImagesCtrl);

img { width: 100px; height: 50px; background: cyan; }
article { padding: 5px 10px; background: lightseagreen; margin-bottom: 5px;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="example"></div>
