javascript – 用数组元素替换字符串

let string = 'My name is [~FirsTNAME] [~LASTNAME]';
let nameArray = ['Peter','Parker'];
let patternToBeReplaced = ['[~FirsTNAME]','[~LASTNAME]']

我想用namearray的元素替换字符串,以便字符串变为’我的名字是Peter Parker’

以下是我解决这个问题的方法 –

patternToBeReplaced.forEach(function (match,index) {
        var output = string.replace(match,nameArray[index]);
});

但这不符合预期.

解决方法

您可以使用 Array#reduce并使用该字符串进行下一次替换.

let string = 'My name is [~FirsTNAME] [~LASTNAME]';
let nameArray = ['Peter','[~LASTNAME]']

string = patternToBeReplaced.reduce((s,m,i) => s.replace(m,nameArray[i]),string);

console.log(string);
