如何检查字符串是否在不同位置包含多个单词

2022-01-25 00:00:00 string regex compare search javascript

所以我有多个这样的字符串:

So I have multiple string that are like this:

字符串 1:那里这是我正在尝试做的一件事，但我不知道如何做.
字符串 2:我真的不知道如何修复它.
字符串 2:希望有人可以帮助我.

String 1: There is this one thing that I'm trying to do but I have no idea how.
String 2: I really have no clue how too fix it.
String 2: Hopefully maybe someone can help me.

现在我还有一个字符串，它是一个搜索输入，可以是任何东西，例如:

Now I also have a string that is a search input that can be anything, for example:

有想法

当用户输入并发送我希望 JavaScript 也与字符串 1 匹配时.
我也想让它返回两个字符串匹配的字符数.

When the user inputs and sends that I want the JavaScript too match with string 1.
Also I would like too have it return by how many characters the two strings are matching.

如果有人可以帮助我，我将非常感激.

If someone can help me with this I would be very grateful.

提前致谢，

推荐答案

如果想知道匹配的长度，例如使用正则表达式:

If you want to know the length of the match, e.g. using regex:

var str = "There idea";

var pattern = new RegExp("\b" + str.replace(/ +/g, "\b.*\b") + "\b", "i")
console.log(pattern)

var strings = [
  "There is this one thing that I'm trying to do but I have no idea how",
  "I really have no clue how too fix it",
  "Hopefully maybe someone can help me"
]

for( i=0; i < strings.length; i++ ) 
  if( res=strings[i].match(pattern) ) 
    console.log( res[0], res[0].length )

 匹配 字边界(零-长度匹配)

 matches a word boundary (zero-length match)
