我使用分割和加入或这个功能:

function replaceAll(text, busca, reemplaza) {
  while (text.toString().indexOf(busca) != -1)
    text = text.toString().replace(busca, reemplaza);
  return text;
}

我知道这不是最好的办法,但你可以尝试一下:

var annoyingString = "Test abc test test abc test test test abc test test abc";

while (annoyingString.includes("abc")) {
    annoyingString = annoyingString.replace("abc", "")
}

说你想用“x”取代所有的“abc”:

let some_str = 'abc def def lom abc abc def'.split('abc').join('x')
console.log(some_str) //x def def lom x x def

我试图思考一些更简单的东西,而不是修改链条的原型。

您可以使用下面的方法

/**
 * Replace all the occerencess of $find by $replace in $originalString
 * @param  {originalString} input - Raw string.
 * @param  {find} input - Target key word or regex that need to be replaced.
 * @param  {replace} input - Replacement key word
 * @return {String}       Output string
 */
function replaceAll(originalString, find, replace) {
  return originalString.replace(new RegExp(find, 'g'), replace);
};

可以用常见的表达方式实现这一点,有几种可以帮助某人:

var word = "this,\\ .is*a*test,    '.and? / only /     'a \ test?";
var stri = "This      is    a test         and only a        test";

取代所有非阿尔法字符,

console.log(word.replace(/([^a-z])/g,' ').replace(/ +/g, ' '));
Result: [this is a test and only a test]

用一个空间替换多个连续空间,

console.log(stri.replace(/  +/g,' '));
Result: [This is a test and only a test]

取代所有 * 字符,

console.log(word.replace(/\*/g,''));
Result: [this,\ .isatest,    '.and? / only /     'a  test?]

取代问题标志(?)

console.log(word.replace(/\?/g,'#'));
Result: [this,\ .is*a*test,    '.and# / only /     'a  test#]

取代引用标志,

console.log(word.replace(/'/g,'#'));
Result: [this,\ .is*a*test,    #.and? / only /     #a  test?]

要取代所有“字符”,

console.log(word.replace(/,/g,''));
Result: [this\ .is*a*test    '.and? / only /     'a  test?]

替换一个特定的词,

console.log(word.replace(/test/g,''));
Result: [this,\ .is*a*,    '.and? / only /     'a  ?]

取代Backslash。

console.log(word.replace(/\\/g,''));
Result: [this, .is*a*test,    '.and? / only /     'a  test?]

以替代前滑,

console.log(word.replace(/\//g,''));
Result: [this,\ .is*a*test,    '.and?  only      'a  test?]

替换所有空间,

console.log(word.replace(/ /g,'#'));
Result: [this,\#.is*a*test,####'.and?#/#only#/#####'a##test?]

替换点,

console.log(word.replace(/\./g,'#'));
Result: [this,\ #is*a*test,    '#and? / only /     'a  test?]

试试这:

String.prototype.replaceAll = function (sfind, sreplace) {
    var str = this;

    while (str.indexOf(sfind) > -1) {
        str = str.replace(sfind, sreplace);
    }

    return str;
};
