英文:
Check user value is present in given array
问题
如您在下面的代码中所见。我尝试检查mergeUserArray的值是否存在于winArray中。但我无法实现它。
因为我希望，如果mergeUserArray中有任何其他数字，它应该匹配是否存在三个数字的组合。就像789在7189中存在一样。
我也尝试了正则表达式，但它也没有起作用。
let regxWinArray = /(123)|(456)|(789)/g;
let winArray = [123, 456, 789];
// let mergeUserArray = [789]; --Value matched
let mergeUserArray = [7189]; // 值不匹配
if (winArray.includes(Number(mergeUserArray))) {
console.log("数字匹配");
} else {
console.log("数字不匹配");
}
英文:
As you can see in below code. I'm trying to check whether mergeUserArray value is present in winArray or not. But I'm not able to achieve it.
Because I want, if any other number is in mergeUserArray it should match if three number combination present in it. Like 789 is present in 7189.
I tried regular expression too but it also didn't work.
let regxWinArray = /(123)|(456)|(789)/g;
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
let winArray = [123,456,789];
// let mergeUserArray = [789]; --Value matched
let mergeUserArray = [7189]; // Value didn't match
if(winArray.includes(Number(mergeUserArray))){
console.log("Number matched");
}
else {
console.log("Number not matched");
}
<!-- end snippet -->

使用全局正则表达式字符匹配并检查找到的字符数量是否匹配：
let winArray = [123, 456, 789];
// let mergeUserArray = [789]; --Value matched
let mergeUserArray = [7189]; // 值不匹配
let match = winArray.some(item => mergeUserArray.some(what => {
const regex = new RegExp(`[${item}]`, 'g');
return what.toString().match(regex)?.length === item.toString().length;
}));
console.log(match);
如果字符的顺序应该匹配：
let winArray = [123, 456, 789];
const hasMatch = mergeUserArray => winArray.some(item => mergeUserArray.some(what => {
const regex = new RegExp(`[${item}]`, 'g');
return what.toString().match(regex)?.join('') === item.toString();
}));
console.log([7189], hasMatch([7189]));
console.log([1897], hasMatch([1897]));
如果我们需要匹配mergeUserArray中的所有值：
let winArray = [123, 456, 789];
let mergeUserArray = [7189, 654];
let match = mergeUserArray.every(what => winArray.some(item => {
const regex = new RegExp(`[${item}]`, 'g');
return what.toString().match(regex)?.length === item.toString().length;
}));
console.log(match);
英文:
Use global regex character match and check whether number of found characters match:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
let winArray = [123, 456, 789];
// let mergeUserArray = [789]; --Value matched
let mergeUserArray = [7189]; // Value didn't match
let match = winArray.some(item => mergeUserArray.some(what => {
const regex = new RegExp(`[${item}]`, 'g');
return what.toString().match(regex)?.length === item.toString().length;
}));
console.log(match);
<!-- end snippet -->
If the order of characters should match:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
let winArray = [123, 456, 789];
const hasMatch = mergeUserArray => winArray.some(item => mergeUserArray.some(what => {
const regex = new RegExp(`[${item}]`, 'g');
return what.toString().match(regex)?.join('') === item.toString();
}));
console.log([7189], hasMatch([7189]));
console.log([1897], hasMatch([1897]));
<!-- end snippet -->
If we need all values in mergeUserArray matched:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
let winArray = [123, 456, 789];
let mergeUserArray = [7189, 654];
let match = mergeUserArray.every(what => winArray.some(item => {
const regex = new RegExp(`[${item}]`, 'g');
return what.toString().match(regex)?.length === item.toString().length;
}));
console.log(match);
<!-- end snippet -->
