如何将我分成小写的单词转换成？我有以下代码。

＆＃13;

/p:DeployOnBuild=true /p:WebPublishMethod=Package /p:PackageAsSingleFile=true /p:SkipInvalidConfigurations=true /p:PackageLocation="$(build.artifactstagingdirectory)\\"

＆＃13;

Answer 1

你可以在JavaScript中做很多事情而不需要自己编写循环。这只是另一个例子。

const title = 'The Quick brown fox';
const words = title.split(' ').map(word => word.toLowerCase());

// print the array
console.log(words);

// print the single words
words.forEach(word => console.log(word));

Answer 2

您只需将Titlewords[i].toLowerCase()分配回Titlewords[i]

即可

＆＃13;

var title = 'The Quick brown fox';

var titleCase = [];


var Titlewords = title.split("");

for (var i = 0; i < Titlewords.length; i++) {
Titlewords[i] = Titlewords[i].toLowerCase();

console.log(Titlewords[i]);

}

＆＃13;

Answer 3

您需要更新值

Titlewords[i] = Titlewords[i].toLowerCase();

＆＃13;

var title = 'The Quick brown fox';

var titleCase = [];


var Titlewords = title.split("");

for (var i = 0; i < Titlewords.length; i++) {
    Titlewords[i] = Titlewords[i].toLowerCase();

    console.log(Titlewords[i]);

}

Answer 4

str.toLowerCase()返回一个字符串，而不是将其设置为更低。你想要做的是

Titlewords[i] = Titlewords[i].toLowerCase();
