在jQuery中为indexOf关键字匹配添加关键字排除

Question

当前匹配的关键字然后执行操作。如何将排除列表纳入下面的功能？

<!-- Product names include Apple iPad, Acer Iconia, Lenovo Thinkpad plus Generic, No Brand--> 
<h1 id="pbtitle">Apple iPad 3</h1> 
<div class="install_option" style="display:none;">    
    <div style="box-sizing:border-box; float:left;"> 
     <a href="https://www.example.com/acc" target="_blank"> 
      <h3 style="font-weight:bold;">Would you like to view accessories?</h3> 
     </a>  
    </div> 
</div> 

var options = ['Acer','Apple','Lenovo']; 
var exclusions = ['Generic','No Brand']; 
var text = $("#pbtitle").text(); 

options.forEach(function(element) { 
    if (text.indexOf(element) != -1) { // if its NOT -1 (-1 = not found)  
     $('.install_option').css('display','block'); // then we found it .. do your magic 
    } 
});

如果文本必须是夹杂物/排除的子字符串，然后

if (options.indexOf(text) != -1 && exclusions.indexOf(text) == -1) 

你需要尝试

var options = ['Cooker hood','Island','Ceiling','Downdraft','Integrated','Canopy','Telescopic','Cabair','Bathroom']; 
var exclusions = ['Filters','Filter','Kit','Foil','Ducting','Switch','Transformer','Silencers', 'Install']; 
var text = $("#pbtitle").text(); 
if (options.indexOf(text) != -1 && exclusions.indexOf(text) == -1) 
{ 
    $('.install_option').css('display','block'); 
} 
else 
{ 
    $('.install_option').css('display','none'); 
}
