Kuxazululiwe: sabela ukuthi uwakhipha kanjani okhefana ochungechungeni

Inkinga enkulu ehlobene nokukhipha okhefana kuyunithi yezinhlamvu ukuthi kungaholela kudatha engalungile. Isibonelo, uma ususa ukhefana kokuthi “John, Paul, George,” iyunithi yezinhlamvu izoba “uJohn, Paul, George.” Lokhu kungase kubangele izinkinga lapho uzama ukufaka iyunithi yezinhlamvu kusizindalwazi noma kolunye uhlelo.

There are a few ways to remove commas from a string in React. One way is to use the .replace() method:

var str = "1,2,3,4,5"; str = str.replace(/,/g, ""); // "12345"

Umugqa wokuqala umemezela okuguquguqukayo okubizwa ngokuthi i-str futhi unikeze iyunithi yezinhlamvu “1,2,3,4,5”. Umugqa wesibili ubiza indlela .replace() ku-str. Indlela .replace() ithatha ama-agumenti amabili: eyokuqala iyinkulumo evamile efana ne(ama)hlamvu okumele ishintshwe, futhi eyesibili i(ama)hlamvu esikhundleni. Kulokhu, sishintsha wonke amakhoma (,) ngaphandle kokuthi (“”). Ngakho-ke u-“1,2,3,4,5” uba “12345”.

Imiyalo yokusebenza sith strings

ReactDOM.render(, document.getElementById(“impande”)); // inikeza ingxenye yohlelo lokusebenza
ReactDOM.render(, document.getElementById(“app”)); // inikeza ingxenye yohlelo lokusebenza kusici esisha se-DOM

Izinhlobo Zezintambo

Kunezinhlobo ezimbalwa zeyunithi yezinhlamvu ku-React.

ReactDOM.render(Sawubona Mhlaba!, document.getElementById('root')); // => Sawubona Mhlaba!

Lokhu kuzohumusha umucu othi “Sawubona, mhlaba!” ku-DOM.

Ungasebenzisa futhi iyunithi yezinhlamvu yangempela:
ReactDOM.render(Lona umucu ongokoqobo., document.getElementById('root')); // => Lona umucu ongokoqobo.
