我想知道是否可以创建一个允许数字，字母和空格但没有标点符号的正则表达式。
发生的事情是我有一个在线贷款申请，并且在街道地址字段中，一些用户在他们的输入中添加逗号（，）。将应用程序导出为CSV后，由于地址字段中包含逗号，CSV文件的逗号位置错误。
我现在已经玩了几个小时的正则表达式并且它很顺利，但它不能完美。我偶尔会得到一个无法验证但没有标点符号的地址。否则它将是一个可接受的输入，但正则表达式不允许它被验证。
因此，我没有试图规定 允许的内容（数字，空格，字母），我是否可以不仅仅规定不允许的内容（标点符号）？后者比前者更有意义。
出于提供信息的目的，我已经提供了我用来测试我的正则表达式的已提交地址列表。我还包括了我一直在研究的正则表达式。非常感谢任何指导或帮助
注意：我添加了无效输入的评论。在无效输入下方，我已经放置了一个现在有效的输入的编辑副本。

正则表达式：
/^(\w*)(\d+)(\w)?\s(\w+(\s?\w+?))+$/
答案 0 :(得分：1)
为什么你需要一个正则表达式？你可以做一些简单的事情：
var address = "My address, with commas not allowed";
var newAddress = address.replace(",","");
正如我在评论中所说，使用此方法，您可以让用户根据需要编写地址，但不会破坏CSV分隔符。您将能够写出这样的地址
Street Nowhere N°10 - 2（12000）
它不会破坏您的CSV。使用正则表达式，此地址将为：
Street Nowhere N 10 2 12000
这不太可读。

更好的解决方案是使用逗号来逃避字段。见https://stackoverflow.com/a/769675/227299。您还需要转义任何双引号。
如果您在JavaScript中执行此操作，则可以执行以下操作：
function escapeCsvValue(val) {
if (val.indexOf(',') > -1 || val.indexOf('"') > -1) {
return '"' + val.replace(/"/g, '""') + '"';
}
return val;
}
var csv = [
['Name, CommaForFun', 'Address'],
['Jack','Calle Ocidental, 2'],
['Jill O"quote"','125, The "cool" place'],
['John','123 Main st'],
];
var escapedCsv = csv.map(function(row){
return row.map(escapeCsvValue).join(',');
});
var csvString = escapedCsv.join('\n');
console.log(csvString);
/*
"Name, CommaForFun",Address
Jack,"Calle Ocidental, 2"
"Jill O""quote""","125, The ""cool"" place"
John,123 Main st
*/
