JavaScript替换字符串中的所有逗号

I want to convert all comma in below string to space or say blank, i tried below code which is only taking care of first comma, I tried global indicator /g as well but that do nothing.

我想将下面的字符串中的所有逗号转换为空格或说空白,我尝试下面的代码只处理第一个逗号,我尝试了全局指标/ g但是什么都不做。

What I am doing wrong?

我做错了什么?

var str="D'Or, Megan#LastName Jr., FirstName#BMW, somename#What, new";
str=str.replace(',','');
alert(str)

Output

D'Or Megan#LastName Jr.,FirstName#BMW,somename#What,new

expected

D'Or Megan#LastName Jr. FirstName#BMW somename#What new

D'Or Megan#LastName Jr. FirstName#BMW somename#新的

To replace any given string u need to use regular expressions. You need to use a RegExp Object to ensure crossbrowser compatibility.

要替换任何给定的字符串,您需要使用正则表达式。您需要使用RegExp对象来确保crossbrowser兼容性。

The use of the flags parameter in the String.replace method is non-standard. For cross-browser compatibility, use a RegExp object with corresponding flags.

String.replace方法中flags参数的使用是非标准的。对于跨浏览器兼容性,请使用带有相应标志的RegExp对象。

//Init
var str = "D'Or, Megan#LastName Jr., FirstName#BMW, somename#What, new";
var regex = new RegExp(',', 'g');

//replace via regex
str = str.replace(regex, '');

//output check
console.log(str); // D'Or Megan#LastName Jr. FirstName#BMW somename#What new

See that fiddle: http://jsfiddle.net/m1yhwL3n/1/ example. Thats how it will work fine for all browsers.
