如何测试字符串类型是否等于另一个JavaScript

Question

假设我有var string1 = "Hello"和string2 = "Hello"如何比较这两个变量，并忽略javascript中的大写字母和标点符号？

Answer 1

Try this:

Use String.toLowerCase() to lowercase a string. To remove punctuation, see this post: How can I strip all punctuation from a string in JavaScript using regex?

Then compare with the === operator. For example:

var string1 = "Hello";
var string2 = "Hello";

string1 = string1.replace(/[.,\/#!$%\^&\*;:{}=\-_`~()]/g,"");
string2 = string2.replace(/[.,\/#!$%\^&\*;:{}=\-_`~()]/g,"");

if (string1.toLowerCase() === string2.toLowerCase()) {
    // Do something
}
