循环遍历可点击元素列表并将html写出到各自的文件

Question

I'm using jQuery to get a list of elements that contain certain key words. I'm able to get the list of elements but I don't know how to loop through each element, click on its child element and download the newly loaded page. Here's the casperjs code I have so far:

var casper = require('casper').create({
    clientScripts: ["/var/www/html/project/public/js/jquery-3.3.1.min.js"]
});

var fs = require('fs');

casper.start('https://m.1xbet.co.ke/en/line/Football/', function () {
    var links = casper.evaluate(function () {
        $.expr[":"].contains = $.expr.createPseudo(function (arg) {
            return function (elem) {
                return $(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0;
            };
        });
        return $("#events-betting").find("li.events__item_head:contains(World cup)");
    });

    var date = new Date(), year = date.getFullYear(), month = date.getMonth() + 1, day = date.getDate();
    var folderName = year + '-' + month + '-' + day;

    // loop would go here to save each file
    var path = "destination/" + folderName + "/1xbet/worldcup-1";
    fs.write(path + ".html", this.getHTML(), "w");

});

casper.run();

I'd like to click on the individual items on the links object - they aren't anchor tags but rather they are clickable divs with inline javascript listening for a click.

The goal is to click on the div that has certain text I'm interested in, then once clicked, I can either choose to scrape the HTML and save it in a file or get the current url; either will be fine for my purposes. Since there could be multiple divs with the desired text, I'd like for a way to loop through each and do perform the same operation.

This is an example of the page I'm interested in:

https://m.1xbet.co.ke/en/line/Football/

The parent element in this case is: #events-betting and nested is a list of li tags with clickable divs.

I can either choose to scrape the HTML and save it in a file or get the current url

Of course the solution is very specific to this exact site, but then again it is quite normal when doing web scraping.

casper.start('https://m.1xbet.co.ke/en/line/Football/', function () {

  var links = casper.evaluate(function () {

    $.expr[":"].contains = $.expr.createPseudo(function (arg) {
      return function (elem) {
        return $(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0;
      };
    });

    var links = [];
    // Better to scrpape .events__title as it contains data-href attribute
    $("#events-betting").find(".events__title:contains(World cup)").each(function (i, item) {
      var lastPartOfurl = item.getAttribute("data-href");
      lastPartOfurl = lastPartOfurl.split("/");
      links.push("https://m.1xbet.co.ke/en/line/Football/" + item.getAttribute("data-champ") + "-" + lastPartOfurl[1]+'/');
    })

    return links;
  });

  console.log(links);
});

The result:

https://m.1xbet.co.ke/en/line/Football/1536237-FIFA-World-Cup-2018/,https://m.1xbet.co.ke/en/line/Football/1204917-FIFA-World-Cup-2018-Winner/,https://m.1xbet.co.ke/en/line/Football/1518431-FIFA-World-Cup-2018-Special-bets/,https://m.1xbet.co.ke/en/line/Football/1706515-FIFA-World-Cup-2018-Teams-Statistics-Group-Stage/
