这应该工作。

String.prototype.replaceAll = function (search, replacement) {
    var str1 = this.replace(search, replacement);
    var str2 = this;
    while(str1 != str2) {
        str2 = str1;
        str1 = str1.replace(search, replacement);
    }
    return str1;
}

例子:

Console.log("Steve is the best character in Minecraft".replaceAll("Steve", "Alex"));

使用分割并加入:

var str = “测试 abc 测试 abc 测试 abc 测试 abc”; var replaced_str = str.split('abc').join(''); console.log(replaced_str);

要取代所有类型的字符,请尝试此代码:

假设我们需要发送“和 \ 在我的行中,然后我们将转换“到“和 \ 到“。

因此,这种方法将解决这个问题。

String.prototype.replaceAll = function (find, replace) {
     var str = this;
     return str.replace(new RegExp(find.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&'), 'g'), replace);
 };

var message = $('#message').val();
message = message.replaceAll('\\', '\\\\'); /*it will replace \ to \\ */
message = message.replaceAll('"', '\\"');   /*it will replace " to \\"*/

我使用Ajax,我需要在JSON格式发送参数,然后我的方法看起来如下:

 function sendMessage(source, messageID, toProfileID, userProfileID) {

     if (validateTextBox()) {
         var message = $('#message').val();
         message = message.replaceAll('\\', '\\\\');
         message = message.replaceAll('"', '\\"');
         $.ajax({
             type: "POST",
             async: "false",
             contentType: "application/json; charset=utf-8",
             url: "services/WebService1.asmx/SendMessage",
             data: '{"source":"' + source + '","messageID":"' + messageID + '","toProfileID":"' + toProfileID + '","userProfileID":"' + userProfileID + '","message":"' + message + '"}',
             dataType: "json",
             success: function (data) {
                 loadMessageAfterSend(toProfileID, userProfileID);
                 $("#<%=PanelMessageDelete.ClientID%>").hide();
                 $("#message").val("");
                 $("#delMessageContainer").show();
                 $("#msgPanel").show();
             },
             error: function (result) {
                 alert("message sending failed");
             }
         });
     }
     else {
         alert("Please type message in message box.");
         $("#message").focus();

     }
 }

 String.prototype.replaceAll = function (find, replace) {
     var str = this;
     return str.replace(new RegExp(find.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&'), 'g'), replace);
 };

要替换一次,使用:

var res = str.replace('abc', "");

多次替换,使用:

var res = str.replace(/abc/g, "");

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", "")
}

与常规表达的i旗案例不敏感

console.log('App started'.replace(/a/g, '')) // Result: "App strted"
console.log('App started'.replace(/a/gi, '')) // Result: "pp strted"
