为什么这0会按预期返回

'https://www.site.com/abc?sk=1'.search('https://www.site.com/abc?')

但这会-1按0预期返回吗？

'https://www.site.com/abc?sk=1'.search('https://www.site.com/abc?sk')

感谢您提供任何提示。

because the ? has a special meaning in regular expressions.

Use indexOf instead (which works with plain strings) when you don't need regular expressions:

'https://www.site.com/abc?sk=1'.indexOf('https://www.site.com/abc?sk')
