如何检查字符串是否包含数组值？

Question

我在编码中休息了几个月，现在我正试图重新开始。

我正在为 Facebook 游戏编写用户脚本，该脚本将从与游戏相关的所有帖子中收集数据，并使用该数据开始接受过程。

但是，我正在尝试为用户引入一个选项，让他们选择他们愿意接受的奖励类型，但我在应用它时遇到了麻烦。

我想要做的是获取帖子标题字符串，并将其与一组选定选项（复选框值）进行比较，以查看帖子标题是否包含数组中的任何值。

这是用户可以选择接受哪些帖子的选项面板：

$("#rightCol").prepend('<div id="bonus_options_panel">'
                       +'<ul id="bonuses"><legend><b>Select Bonuses to accept...</b></legend>'
                       +'<li><label>Hungry No More <input type="checkbox" value="heroic companions!" class="bonus_select_option"></label></li>'
                       +'<li><label>Pikemen <input type="checkbox" value="extra pikes!" class="bonus_select_option"></label></li>'
                       +'<li><label>Swordsmen <input type="checkbox" value="recruited swordsmen!" class="bonus_select_option"></label></li>'
                       +'<li><label>Valuable Treasure <input type="checkbox" value="valuable treasure!" class="bonus_select_option"></label></li>'
                       +'<li><label>Jousting Competition <input type="checkbox" value="jousting game!" class="bonus_select_option"></label></li>'
                       +'<li><label>Gamble <input type="checkbox" value="wants to gamble." class="bonus_select_option"></label></li>'
                       +'<li><label>Extra Lumber <input type="checkbox" value="has extra lumber!" class="bonus_select_option"></label></li>'
                       +'<li><label>Foreign Traders <input type="checkbox" value="attracted foreign traders!" class="bonus_select_option"></label></li>'
                       +'<li><label>Buxom Wenches <input type="checkbox" value="inviting friends over!" class="bonus_select_option"></label></li>'
                       +'<li><label>Plague <input type="checkbox" value="kingdom has the plague!" class="bonus_select_option"></label></li>'
                       +'<li><label>Legendary Bard <input type="checkbox" value="hosting a legendary bard!" class="bonus_select_option"></label></li>'
                       +'<li><label>Wild Horses <input type="checkbox" value="found wild horses!" class="bonus_select_option"></label></li>'
                       +'<li><label>Mercenary Armies <input type="checkbox" value="mercenary armies with you." class="bonus_select_option"></label></li>'
                       +'<li><label>Famed Hero <input type="checkbox" value="feasting with a famed hero!" class="bonus_select_option"></label></li>'
                       +'<li><label>Queen Parading <input type="checkbox" value="Queen is parading!" class="bonus_select_option"></label></li>'
                       +'<li><label>Wanted Criminal <input type="checkbox" value="caught a wanted criminal!" class="bonus_select_option"></label></li>'
                       +'<li><label>Rolling Logs <input type="checkbox" value="has extra logs!" class="bonus_select_option"></label></li>'
                       +'<li><label>Archery Game <input type="checkbox" value="holding a Archery game!" class="bonus_select_option"></label></li>'
                       +'</ul>'
                       +'</div>');

这里是一个帖子标题字符串的例子： 利亚姆艾伦需要英雄伙伴！

我一直在创建一个复选框值数组，如下所示：

var bonus = [];
$("input.bonus_select_option:checked").each(function(){
     bonus.push($(this).val());
 });

我现在想做的是，获取帖子的标题字符串，并检查它是否包含任何数组值，但这样做有问题。

任何帮助将不胜感激，并提前致谢！

Answer 1

试试 Array.join 和 String.search 方法：

var re = new RegExp('(' + bonus.join('|') + ')');
console.log('Liam Allan is need of heroic companions!'.search(re) != -1);  //  true  if contains

Answer 2

从您如何填充 bonus 变量开始：

  var title = 'Liam Allan is need of heroic companions!';
  var bonus = [];
  $("input.bonus_select_option:checked").each(function(){
        bonus.push($(this).val());
  });
  $.each(bonus, function(key, value){
        if(title.indexOf(value) > 0) ... //Do something 
  });

例如：

  var title = 'Liam Allan is need of heroic companions!';
  var bonus = [];
  bonus.push('heroic companions!');
  bonus.push('recruited swordsmen!');
  bonus.push('feasting with a famed hero!');

  $.each(bonus, function(key, value){
    if(title.indexOf(value) > 0) alert(value + " found in title");
  });

会回来

  heroic companions! found in title
