Chromeで、aタグのURLとテキストをCSVで取得(自分用メモ)

jQueryの読み込み

jQueryのバージョンはコピペなので古い。。。

    if(typeof jQuery === "undefined") {
        var script = document.createElement('script');
        script.type = 'text/javascript';
        script.src = '//code.jquery.com/jquery-3.5.1.min.js';
        document.head.appendChild(script);
    }

CSV保存関数

var downloadAsTextFile = function(fileName, content) {
    var bom = new Uint8Array([0xEF, 0xBB, 0xBF]);
    var blob = new Blob([bom, content]);
    var url = window.URL || window.webkitURL;
    var blobURL = url.createObjectURL(blob);

    var a = document.createElement('a');
    a.download = fileName;
    a.href = blobURL;
    a.click();  
};
var downloadAsCSVFile = function(fileName, rows) {
  var content = "";
  for( var i in rows) {
    var ary = rows[i];
    for (var j = 0, m = ary.length; j < m; ++j) {
      content += '"' + ("" + ary[j]).replace('"', '""') + '"';
      if (j !== m) {
        content += ',';
      }
    }
    content += '\n';
  }
  downloadAsTextFile(fileName, content);
};
var Queue = function() {
  this.promise = Promise.resolve(true);
  this.async = (action)      => this.promise = this.promise.then(() => new Promise((resolve) => action(resolve)));
  this.sync  = (action)      => this.async((resolve) => { action(); resolve(); });
  this.delay = (delay)       => this.async((resolve) => setTimeout(resolve, delay));
  this.open  = (url, action) => this.async((resolve) => {
    var w = window.open(url, "dummy", 'width=100,height=100');
    $(w).on('load', () => { action(w); w.close(); resolve(); });
  });
};

aタグ取得

tbl = $('div#divSettingList tr td div a').map((i, e) => [[e.text, e.href]]).get()
downloadAsCSVFile('hoge.csv', tbl)

おまけ

SBIの積立設定一覧から項目を取得。
前も作った気がするけど、ページ構成が変わって使えない・・・

var q = new Queue();
var rows = [];
$('div#divSettingList tr td div a').each((i, e) => {
    var name = $(e).text()
    var amount = $(e).closest('td').find("p:contains('設定金額')").text();
    q.open(e.href, (w) => {
        var t = $(w.document);
        var category = t.find("p:contains('モーニングスターカテゴリ')").closest("p").next("p").text().trim()
        var code     = t.find("p:contains('協会コード')").closest("tr").next("tr").text().trim()
        var cost     = t.find("p:contains('信託報酬')").closest("tr").next("tr").text().trim()
        var row = [name, amount, category, code, cost]
        rows.push(row);
        console.log(row)
    })
})
q.sync(() => downloadAsCSVFile('hoge.csv', rows))
