Question

当前匹配的关键字然后执行操作。如何将排除列表合并到下面的函数中？

<!-- 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
    }
});

如果文本必须是包含/排除的子串，那么

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'); 
}

在jQuery中为indexOf关键字匹配添加关键字排除项
