创建一个函数，它接受要替换的单词字符串和要重复的字符串直到达到长度，然后简单地继续附加到变量直到达到长度:

function replaceTextWithLength(textToReplace, replaceText) {
    var length = textToReplace.length;
    var text = "";
    while (text.length < length) {
        text += replaceText;
    }

    return text.substring(0, length);
}

var words = replaceTextWithLength("Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed id dui tincidunt", "sample text ");
console.log(words);
