没有内置函数来替换所有出现的单词。您需要创建自己的函数。
假设以下是我们的字符串 −
var sentence = "Yes, My Name is John Smith. I live in US. Yes, My Favourite Subject is JavaScript";
示例
以下是代码 −
var sentence = "Yes, My Name is John Smith. I live in US. Yes, My Favourite Subject is JavaScript";
console.log(sentence);
function replaceYesWithHi(word, sentence, replaceValue) {
return sentence.split(word).join(replaceValue);
}
var replacementofYesWithHi = replaceYesWithHi("Yes", sentence, "Hi");
console.log(replacementofYesWithHi);
要运行上述程序，请使用以下命令 −
node fileName.js.
这里，文件名是 demo240.js。
输出
输出如下 −
PS C:\Users\Amit\javascript-code> node demo240.js Yes, My Name is John Smith. I live in US. Yes, My Favourite Subject is JavaScript Hi, My Name is John Smith. I live in US. Hi, My Favourite Subject is JavaScript
