我正在創(chuàng)建一個(gè)將 pdf 解析為文本的服務(wù)。當(dāng)我有該文本時(shí)，我必須匹配一組單詞。每次匹配時(shí)，它都會(huì)增加一個(gè)計(jì)數(shù)器。到目前為止，一切都很好。困難在于，在解析為文本時(shí)，我無法檢查我在 pdf 的哪一頁(yè)。我已經(jīng)意識(shí)到，在拆分中，每次出現(xiàn)兩個(gè)連續(xù)的換行符（/n/n）就意味著發(fā)生了換頁(yè)。我想做的是檢查頁(yè)面是否已更改，并且除了計(jì)算一個(gè)單詞總共被找到的次數(shù)外，還要說出它在哪些頁(yè)面上。例子let data =  `resignations / resignations. adm. mancom .: berenguer llinaresappointments. adm. unique: calvo valenzuela. other concepts: change of the administrative body:joint administrators to sole administrator. change of registered office. ptda colomer, 6Official Gazette of the Commercial Registryno. 182 Friday, September 18, 2020 p. 33755cve: borme-a-2020-182-03 verifiable insarria). registry data. t 2257, f 100, s 8, h a 54815, i / a 4 (10.09.20) .`let wordsToSearch = ['resignations', "administrators"]    wordsToSearch.forEach((word) => {// inside of here would like to have track of the page as well        let stringArray = data.split(' ');        let count = 0;        let result = ""        for (var i = 0; i < stringArray.length; i++) {            let wordText = stringArray[i];            if (new RegExp(word).test(wordText)) {                count++            }        }        // the expected result would word has appeared count times in the pages etc        result += `${word} has appeared ${count} times\n`        console.log(result)        /*        resignations has appeared 2 times        administrators has appeared 1 times        */    })如果有人也想出另一種方法，那就太好了
