очистить данные внутри тега скрипта и изолировать элементы

/ 07 апреля 2020

У меня возникла проблема с очисткой данных внутри тега скрипта. Я хотел бы получить данные внутри jsonSwatchConfig [], особенно каждый из атрибутов 'option_id' и 'us'. 

var jar = require('request').jar();
var request = require('request').defaults({ jar: jar });
var cheerio = require("cheerio");
var cloudscraper = require('cloudscraper');
var fs = require('fs');
const logT = require('log-timestamp');
var open = require('open');
var today = new Date();
var randomsize;
var webdriver = require('selenium-webdriver');
var request = require("request")
var cheerio = require("cheerio")

var sizes =[]

function product() {
    console.log("Obtaining Product Page..")
    request.get({
        url: 'https://www.sivasdescalzo.com/en/nike-air-max-270-react-eng-cd0113-400',
        jar: request.jar(),

    }, function(error, response, body) {
        var $ = cheerio.load(body);
        var script = $('body > script').map((i, x) => x.children[0])
                                 .filter((i, x) => x && 
        x.data.match(/jsonSwatchConfig/)).get(0);
        if (script){
            var scriptText = script.data.replace(/\r?\n|\r/g, "")
            console.log(scriptText.split('"Svd_Catalog/js/svd.swatch.renderer"')[1].replace(" ",""));
        }
    });
}

Мой фактический вывод: 

    :{                "jsonSwatchConfig": 
[{"option_id":"18","us":"7","eu":"40","uk":"6","cm":"25"}, 
{"option_id":"16","us":"8","eu":"41","uk":"7","cm":"26"}, 
{"option_id":"14","us":"9","eu":"42.5","uk":"8","cm":"27"}, 
{"option_id":"12","us":"10","eu":"44","uk":"9","cm":"28"}, 
{"option_id":"10","us":"11","eu":"45","uk":"10","cm":"29"}, 
{"option_id":"8","us":"12","eu":"46","uk":"11","cm":"30"}, 
{"option_id":"105","us":"10.5","eu":"44.5","uk":"9.5","cm":"28.5"}, 
{"option_id":"117","us":"11.5","eu":"45.5","uk":"10.5","cm":"29.5"}, 
{"option_id":"110","us":"7.5","eu":"40.5","uk":"6.5","cm":"25.5"}, 
{"option_id":"121","us":"8.5","eu":"42","uk":"7.5","cm":"26.5"}, 
{"option_id":"114","us":"9.5","eu":"43","uk":"8.5","cm":"27.5"}] }              },        
"*" : {            "Magento_Swatches/js/catalog-add-to-cart": {}        }    }

Я пробую много время, но я не нашел способ получить то, что я хочу. Использовал split и remove.

Это источник тегов html:

    },
    "*" : {
        "Magento_Swatches/js/catalog-add-to-cart": {}
    }
}</script>

Я хотел бы знать, как это сделать, и самый безопасный способ. Я могу продолжать разбивать и удалять, но я не думаю, что это правильный способ выполнить такую ​​задачу.

Как насчет использования RegExp? 

var pattern = /"jsonSwatchConfig": (\[.*\])/;
var results = scriptText.match(pattern)[1];

Редактировать : чтобы извлечь атрибуты option_id и us, сначала необходимо преобразовать это из строки к объекту. Приведенный выше код дает вам массив jsonSwatchConfig в виде строки, а не фактического массива объектов, поэтому вы можете сделать следующее (продолжая из приведенного выше кода): results = JSON.parse(results), который теперь даст вам данные в виде массива объектов. , Чтобы получить доступ к указанным c атрибутам, вы можете сделать что-то вроде 

results.forEach(result => {
    var x = result.option_id;
    var y = result.us;
    console.log({ x, y });
});
