检查数组中的部分匹配

问题描述

我有一个JavaScript数组，其中包含一些在请求创建用户帐户时无法使用的单词。

I have a JavaScript array that contains some words that cannot be used when requesting user accounts to be created.

我正在尝试循环请求的帐户并检查他们反对一个字过滤器。如果它们包含任何单词，则该值将移动到无效帐户数组。

I am trying to loop over the accounts requested and check them against a word filter. If they contain any of the words, the value is moved to an array of "Invalid Accounts".

// Create our arrays
var blacklist = ["admin", "webform", "spoof"];
var newAccounts = ["[email protected]", "[email protected]", "[email protected]"];
var invalidAccounts = [];

// I need to check if any of the new accounts have matches to those in the blacklist.
// [email protected] would need to be pushed into the invalidAccounts array because it
// contains the word admin. Although interweb contains the word web, it does not contain
// the full word, webform, so should be ignored.

// Loop over the blacklist array
for(var x = 0; x < blacklist.length; x++){
  if(blacklist[x].indexOf(newAccounts) > -1){
    alert(blacklist[x] + " is in the blacklist array");
    // Push the newAccounts value into the invalidAccounts array since it contains
    // a blacklist word.
  } else {
    alert('no matches');
  }
}

我需要在上面的代码中更改为它是否与提到的部分字符串匹配？

What do I need to change in the above code to have it match the partial strings such as mentioned?

推荐答案

您可能不需要全部使用但这应该是有帮助的：

You probably won't need to use all of this but it should be helpful none the less:

var blacklist = ["admin", "webform", "spoof"];
var newAccounts = ["[email protected]", "[email protected]", "[email protected]"];
var invalidAccounts = [];

// transform each email address to an object of the form:
// { email: string, valid: boolean }
var accountObjects = newAccounts.map(function (a) {
    return { email: a, valid: true };
});

// loop over each account
accountObjects.forEach(function (account) {
    // loop over the blacklisted terms
    blacklist.forEach(function (blacklisted) {
        // check to see if your account email address contains a black listed term
        // and set the valid property accordingly
        account.valid = account.email.search(blacklisted) === -1;
    });
});

// filter accountObjects, validAccounts will now contain an array of valid objects
var validAccounts = accountObjects.filter(function (a) {
    return a.valid;
});

// back to the original type of a string array
var validEmailAddresses = validAccounts.map(function (a) {
    return a.email;
});
