Removing control ASCII characters

Question

function RemoveASCIIControlCharacters(xmlString) {
    var cleanXmlString = xmlString.replace(/VT/g,'');
    cleanXmlString = cleanXmlString.replace(/SUB/g, '');
    return cleanXmlString;
}

Please replace VT and SUB with real control character.

The removal of the VT control character works. However the removal of the SUB control character fails.

How do I filter out the SUB(0x1A) control character?

Answer 1

使用\ xY，其中Y是十六进制字符代码，例如。对于两者：

return cleanXmlString.replace(/[\x0b\x1a]/g, ''));

Answer 2

您可以使用八进制字符转义和范围：/[\0-\32]/g
