XRegExp to JavaScript RegExp

Question

我想将XRegExp函数转换为纯JavaScript RegExp。基本上，所有非字母数字字符都将替换为"_“，包括空格。

正文

这是一个示例文本*\&^%$#@!~‘

就像

This_is_a_sample_text____________

我有下面的代码。

var text = "This is a sample text *\&^%$#@!~'";
var matchAlphaNumeric = new XRegExp('[\\p{L}\\p{N}]');
var result = substituteNotAcceptedCharactersforTag(text, matchAlphaNumeric);
function substituteNotAcceptedCharactersforTag(text, regex) {
        var tagWithAlphaAndNumeric = '';
        for (var i = 0; i < text.length; i++) {
            var characterBeingTested = text.charAt(i);
            if (XRegExp.test(characterBeingTested, regex) === true) {
                tagWithAlphaAndNumeric += characterBeingTested.toLowerCase();
            } else {
                tagWithAlphaAndNumeric += '_';
            }
        }
        return tagWithAlphaAndNumeric;
    }

用_替换所有非字母数字字符

s = s.replace(/[^0-9A-Za-z]/g, '_');
