我怎樣才能得到一個TD

Question

我想這td

我的代碼

function check() { 
    var e = document.getElementById("ticket_category_clone"); 
    var str = e.options[e.selectedIndex].text; 

    alert(str); 
    if (str === "Hardware") { 
     SPICEWORKS.utils.addStyle('#ticket_c_hardware_clone{display: none !important;}'); 
    } 

} 

SPICEWORKS.app.helpdesk.ready(check); 

價值和Bang它什麼都不做，什麼可能是問題的價值？

的HTML srry在乞討

<select id="ticket_category_clone" name="ticket[category]" hdpp="ticket_category"> 
    <option value=""></option><option value="Hardware">Hardware</option> 
    <option value="Software">Software</option> 
    <option value="Rede" selected="selected">Rede</option> 
    <option value="Pedidos">Pedidos</option> 
    <option value="Formação/Dúvida">Formação/Dúvida</option> 
    <option value="Outro">Outro</option><option value="#edit_categories#">Edit Categories...</option></select>
