str.replace(new RegExp(".","gm")," ")

让a = "从前有一个国王。opeator传播。让。版本。const。”;

let data = a.r eall ("."，"");

答案:data = "曾经有一个king spread operator let ver const";

您需要对该字符串使用replaceAll()方法。

String.prototype.replaceAll = function(character,replaceChar){
    var word = this.valueOf();

    while(word.indexOf(character) != -1)
        word = word.replace(character,replaceChar);

    return word;
}

mystring.replace(new RegExp('.', "g"), ' ');

str.replace(new RegExp(".","gm")," ")

示例:我想将所有双引号(")替换为单引号(')，然后代码将如下所示

var str= "\"Hello\""
var regex = new RegExp('"', 'g');
str = str.replace(regex, '\'');
console.log(str); // 'Hello'
