Can you also please advices me with the invalid characters that when passed to the query string or URL crashes the page or produces undesired results ? e.g passing apostrophe (') produces undesired result are their any more of them.
您能否也建议我使用无效字符，这些字符在传递给查询字符串或 URL 时会导致页面崩溃或产生不想要的结果？例如，传递撇号 (') 会产生不希望的结果。

var str = "this's kelly"
str = str.replace(/'/g, 'A');
The reason your version wasn't working is because str.replacereturns the new string, without updating in place.
您的版本无法正常工作的原因是因为str.replace返回了新字符串，而没有进行适当的更新。
I've also updated it to use the regular expressionversion of str.replace, which when combined with the goption replaces all instances, not just the first. If you actually wanted it to just replace the first, either remove the gor do str = str.replace("'", 'A');
我还更新了它以使用 的正则表达式版本str.replace，当与g选项结合使用时，它会替换所有实例，而不仅仅是第一个。如果您真的希望它只是替换第一个，请删除g或执行str = str.replace("'", 'A');

Do this:
做这个：
str = str.replace("'","A");
回答by TommyBs
str = str.replace("'", "A");
str = str.replace("'", "A");
Your running the function but not assigning it to anything again so the var remains unchanged
您运行该函数但不再将其分配给任何东西，因此 var 保持不变
