我有標(biāo)有前綴“add-product-”的輸入框 ID，我想用任何東西替換“add-product-”。所以我嘗試使用data[field.id].replace("add-product-", "");但它給了我錯(cuò)誤：[Error] TypeError: undefined is not an object (evaluating 'data[field.id].replace')這是我的代碼：function addproduct(){    var datafeilds = Array.from(document.querySelectorAll("[id^='add-product-']"));    var data = {};    datafeilds.forEach(function(field){        data[field.id].replace("add-product-", "");        data[field.id] = field.value;    });    console.log(data);}輸出是：[Log] {add-product-name: "", add-product-overlay1: "", add-product-overlay2: "", add-product-wholesale_price: "", add-product-delivery_price: "", …}我希望它是：[Log] {name: "", overlay1: "", overlay2: "", wholesale_price: "", delivery_price: "", …}
