试试这:

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

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

    return str;
};

var myName = 'r//i//n//o//l////d';
var myValidName = myName.replace(new RegExp('\//', 'g'), ''); > // rinold
console.log(myValidName);

var myPetName = 'manidog';
var renameManiToJack = myPetName.replace(new RegExp('mani', 'g'), 'jack'); > // jackdog

str = "Test abc test test abc test test test abc test test abc"

str.split(' ').join().replace(/abc/g,'').replace(/,/g, ' ')

以前的答案太复杂了,只需使用替代功能如下:

str.replace(/your_regex_pattern/g, replacement_string);

例子:

var str = “测试 abc 测试 abc 测试 abc 测试 abc”; var res = str.replace(/[abc]+/g, ""); console.log(res);

可替代的独特价值

String.prototype.replaceAll = function(search_array, replacement_array) { // var target = this; // search_array.forEach(function(substr, index) { if (typeof replacement_array[index]!= "undefined") { target = target.replace(new RegExp(substr, 'g'), replacement_array[index] ) }); // return target; }; // Use: var replacedString = "This topic commented o

以下功能为我工作:

String.prototype.replaceAllOccurence = function(str1, str2, ignore)
{
    return this.replace(new RegExp(str1.replace(/([\/\,\!\\\^\$\{\}\[\]\(\)\.\*\+\?\|\<\>\-\&])/g,"\\$&"),(ignore?"gi":"g")),(typeof(str2)=="string")?str2.replace(/\$/g,"$$$$"):str2);
} ;

现在,请称这些功能如下:

"you could be a Project Manager someday, if you work like this.".replaceAllOccurence ("you", "I");
