Question

我正在创建一个商店网站，但是我收到的数据馈送是一种用竖杠而不是逗号分隔的格式。我希望能够从文本文件中读取内容，以将内容显示到网页中，并允许客户搜索商品。

示例行：

710734240|8mm - Men's Freemason Ring / Masonic Ring - Gold and Black Inlay Tungsten Ring Comfort Fit|73628|

我尝试遍历分离出的项目并将它们放入自己的数组中。

        const my_data = 'test_data.txt';

        async function getData() {

            const response = await fetch(my_data);
            const data = await response.text();
            //console.log(data);

            const rows = data.split('\n').splice(1);
            rows.forEach(elt => {
                const row = elt.split('|');

                row.forEach(item => {
                    const items = item.split(',');
                    //    const filtered = items.filter(function (el){
                    //    return el != ""; 
                    const lens = items.length;
                    //document.getElementById('data').innerHTML = rows + "<br>";

                    var goods = {
                        ProductId: row[0],
                        Name: row[1],
                        MechantId: row[2],
                        Mechant: row[3],
                        link: row[4],
                        thumbnail: row[5],
                        bigImage: row[6],
                        Price: row[7],
                        RetailPrice: row[8],
                        mainCat: row[9],
                        subCat: row[10],
                        Description: row[11],

                    };
                    document.getElementById('data').innerHTML = goods.Description + "<br>";
                });


                console.log(row);
                //console.log(lens);



            });
        }
        getData();

也许您想从这里开始：

ob_end_clean();
$writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save('php://output');

let list = {};

const rows = `710734240|8mm - Men's Freemason Ring / Masonic Ring - Gold and Black Inlay Tungsten Ring Comfort Fit|73628|
710734241|9mm - Men's Freemason Ring / Masonic Ring - Gold and Black Inlay Tungsten Ring Comfort Fit|73628|
710734242|10mm - Men's Freemason Ring / Masonic Ring - Gold and Black Inlay Tungsten Ring Comfort Fit|73628|`
  .split("\n")
  .forEach(row => { // destructing the rows curtesy of Code Maniac
    ( 
      ([ProductId, Description, subCat]) => list[ProductId] = { Description, subCat }  
    )( row.split("|") )
  })


// displaying example

let dl = document.createElement("dl");
let content = []
Object.keys(list).forEach(
  k => content.push(`<dt>${k}</dt><dd>${list[k].Description}</dd>`)
)
dl.innerHTML = content.join("");
document.getElementById("container").appendChild(dl)

dl {
  display: flex;
  flex-flow: row wrap;
  border: solid #333;
  border-width: 1px 1px 0 0;
}

dt {
  flex-basis: 10%;
  padding: 2px 4px;
  background: #333;
  text-align: right;
  color: #fff;
}

dd {
  flex-basis: 80%;
  flex-grow: 1;
  margin: 0;
  padding: 2px 4px;
  border-bottom: 1px solid #333;
}
