爲if語句使用Javascript對象變量

我使用javascript來顯示商店購物籃的信息。我知道如何抽取數據並從中創建元素，但我需要使用if語句的變量之一，但我不確定如何使用這些變量。爲if語句使用Javascript對象變量

如果這是true："isPunchOut": false,然後輸入要定位與jQuery和做類似$(".button").remove();

我該怎麼辦呢？

var retailerData = { 
"del": { 
    "zip": "", 
    "city": "" 
}, 
"user": { 
    "country": "", 
    "phone": "", 
    "nbrOrders": 0, 
    "isPunchOut": false, 
    "name": "", 
    "salesPerson": "", 
    "customerNo": "", 
    "email": "" 
}, 
"order": { 
    "shippingSum": 0.0, 
    "shippingFormatSum": "\u20AC0", 
    "orderno": "0", 
    "orderFormatSum": "\u20AC130", 
    "voucher": "", 
    "orderFormatVat": "\u20AC27,30", 
    "currencySymbol": "\u20AC", 
    "currency": "EUR", 
    "orderVat": 27.3, 
    "orderSum": 130.0, 
    "items": [{ 
     "imageURI": "\/imgr\/8c82380c-65f5-43aa-83ad-fae1215b5b39\/70\/70", 
     "qtyAvail": 7, 
     "price": 130.0, 
     "qty": 1, 
     "artno": "D630-T7100-GE-REF", 
     "vat": 27.3, 
     "formatVat": "\u20AC27,30", 
     "id": "52307", 
     "label": "D630 C2D-T7100&#x2F;2GB&#x2F;80GB&#x2F;DVD&#x2F;14&#34;&#x2F;NO COA WLAN", 
     "category": "Computers - Notebooks", 
     "formatPrice": "\u20AC130", 
     "manufacturer": "Dell" 
    }] 
    } 
}

jQuery和HTML的[MCVE]請。 – zer00ne

您可以在下面的JS代碼來看看以供參考：

var isPunchOut = retailerData["user"]["isPunchOut"]; 
if(isPunchOut === false) 
    $(".button").remove();

我會說你應該先嚐試一些代碼，並把你卡住的地方。我們不是在這裏爲你的問題編寫代碼。

var retailerData = { 
"del": { 
    "zip": "", 
    "city": "" 
}, 
"user": { 
    "country": "", 
    "phone": "", 
    "nbrOrders": 0, 
    "isPunchOut": false, 
    "name": "", 
    "salesPerson": "", 
    "customerNo": "", 
    "email": "" 
}, 
"order": { 
    "shippingSum": 0.0, 
    "shippingFormatSum": "\u20AC0", 
    "orderno": "0", 
    "orderFormatSum": "\u20AC130", 
    "voucher": "", 
    "orderFormatVat": "\u20AC27,30", 
    "currencySymbol": "\u20AC", 
    "currency": "EUR", 
    "orderVat": 27.3, 
    "orderSum": 130.0, 
    "items": [{ 
     "imageURI": "\/imgr\/8c82380c-65f5-43aa-83ad-fae1215b5b39\/70\/70", 
     "qtyAvail": 7, 
     "price": 130.0, 
     "qty": 1, 
     "artno": "D630-T7100-GE-REF", 
     "vat": 27.3, 
     "formatVat": "\u20AC27,30", 
     "id": "52307", 
     "label": "D630 C2D-T7100&#x2F;2GB&#x2F;80GB&#x2F;DVD&#x2F;14&#34;&#x2F;NO COA WLAN", 
     "category": "Computers - Notebooks", 
     "formatPrice": "\u20AC130", 
     "manufacturer": "Dell" 
    }] 
    } 
} 

if(retailerData.user.isPunchOut){ 
//your jquery operation 
}

怎麼樣？

if (!retailerData.user.isPunchOut) { 
     $(".button").remove(); 
    }
