还有一个很容易理解的解决方案:)

var newstring = mystring.split('.').join(' ');

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

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

    return word;
}

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'

var mystring = 'okay.this.is.a.string';
var myNewString = escapeHtml(mystring);

function escapeHtml(text) {
if('' !== text) {
    return text.replace(/&/g, "&")
               .replace(/&lt;/g, "<")
               .replace(/&gt;/g, ">")
               .replace(/\./g,' ')
               .replace(/&quot;/g, '"')
               .replace(/&#39/g, "'");
} 

String.prototype.replaceAll = function (needle, replacement) {
    return this.replace(new RegExp(needle, 'g'), replacement);
};

简单的方法

“先生”.split (' . ') . join (" ");
