An warware: kwafi alamar digo

Da wayewar zamani na dijital, hulɗar tsakanin masu amfani da aikace-aikacen software ta samo asali cikin sauri, kuma ɗayan irin wannan juyin shine manufar maimaita abun ciki ta amfani da alamar kwafi. Wannan labarin ya zurfafa cikin fahimtar alamar kwafin ɗigo, yadda ake aiwatar da shi a cikin TypeScript, da coding ɗin da ke cikin tsarin.

Alamar kwafin ɗigo ta zama ta yaɗu sosai a sashi saboda yaɗuwar amfani da ita a cikin ayyukan allo a faɗin dandamali na dijital. Misali, lokacin da mai amfani ya zaɓi rubutu kuma ya danna “kwafi”, ana adana abubuwan da aka kwafi a cikin allo na tsarin wanda za a iya amfani da shi don “manna” wani wuri.

Komai rikiɗar matsalar zata iya zama kamar, kowace tambaya ta ƙididdigewa za a iya rarraba ta zuwa sassan da za a iya sarrafawa. Matsalarmu tana buƙatar fahimtar tsarin rubutu na TypeScript, gudanar da taron a cikin Tsarin Abubuwan Abubuwan Takaddun Takaddun (DOM), da APIs na allo.

const sourceText = document.getElementById('source-text');
const copyButton = document.getElementById('copy-button');

copyButton.addEventListener('click', function(e) {
  const selection = window.getSelection();
  const range = document.createRange();
  
  range.selectNodeContents(sourceText);
  selection.removeAllRanges();
  selection.addRange(range);

  document.execCommand('copy');
  selection.removeAllRanges();
});

Wannan snippet code yana fara zaɓar abun ciki na rubutu da muke son kwafa, ya kafa kewayo, kuma yana haɗa kewayon zuwa zaɓin mu. Aikin ƙarshe `document.execCommand('kwafi');' yana kwafin zaɓin zuwa allon allo yayin da na gaba yana share zaɓin.

Bari mu shiga cikin wasu fitattun ayyuka da APIs da aka yi amfani da su a cikin maganinmu:

• DOM (Tsarin Abubuwan Abubuwan Takardu): Wannan shine hanyar haɗin shirye-shirye don fayilolin HTML da XML. Yana wakiltar tsarin takaddun kuma yana ba da damar harshen shirye-shirye don yin hulɗa da sarrafa tsari, salo, da abun ciki. A cikin yanayinmu, muna amfani da TypeScript.
• samunZaɓi kuma cire AllRanges Hanyar: `window.getSelection()' hanya ce ta JavaScript da ake amfani da ita don samun zaɓi na yanzu. Lokacin da aka kira wannan hanyar, tana mayar da abin Zaɓi wanda ke wakiltar kewayon rubutun da aka zaɓa a halin yanzu. Ana amfani da hanyar ''cireAllRange'' don share zaɓi.
• Hanyar umarni: Ana amfani da hanyar `execCommand' don aiwatar da umarni akan takaddar yanzu. A cikin yanayinmu, umarnin shine 'kwafi', don kwafi kewayon da aka zaɓa zuwa allon allo.

Za mu fara da samun rubutun da ake buƙatar kwafi ta amfani da `getElementById'. Aikin 'addEventListener' da aka ƙara zuwa maɓallin kwafi yana ɗauka a cikin wani lamari kuma yana haifar da aikin da aka sanya masa. A cikin wannan aikin, mun kafa kewayon. Sannan muna amfani da 'selectNodeContents' don zaɓar abubuwan da ke cikin ɓangaren rubutun mu.

A ƙarshe, ana amfani da `execCommand('kwafi')` don kwafi zaɓin rubutu zuwa allon allo kuma ana amfani da `selection.removeAllRanges()` don share zaɓin bayan kwafi.

Canje-canje masu ma'ana da hanyoyin da aka sanya su daidai a lambar mu ta TypeScript sun tabbatar da cewa bayanin kansa ne kuma mai sauƙin fahimta. A cikin tsarin, mun kuma tabbatar da cewa lambar mu ta bi mafi kyawun ayyuka da aka ba da shawarar a cikin TypeScript.

Lokacin da ake magance matsalolin nan gaba, fahimtar alamu da hanyoyin da aka yi amfani da su a nan zai sauƙaƙa kewayawa da isa ga ingantaccen bayani.
