问题是，在使用 Select 器 Select 产品类型的网页上， Select 器中的选项(值)不会显示
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Products</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<h1>Список продуктов</h1>
<form id="addProductForm">
<label for="productName">Product Name:</label>
<input type="text" id="productName" name="productName" required>
<label for="weight">Weight:</label>
<input type="number" id="weight" name="weight" required>
<label for="typeSelect">Product Type:</label>
<select class="form-control" id="typeSelect" name="TypeID">
{{ range .Rows}}
<option value="{{.ProductType.IDType}}">{{ .ProductType.NameType }}</option>
{{ end }}
</select>
<label for="unit">Unit:</label>
<input type="text" id="unit" name="unit" required>
<label for="description">Description:</label>
<input type="text" id="description" name="description" required>
<label for="pricePickup">Price Pickup:</label>
<input type="number" id="pricePickup" name="pricePickup" required>
<label for="priceDelivery">Price Delivery:</label>
<input type="number" id="priceDelivery" name="priceDelivery" required>
<button type="button" onclick="addProduct()">Add Product</button>
</form>
<table id="productTable">
<tr>
<th>ID продукта</th>
<th>ID типа</th>
<th>Название продукта</th>
<th>Вес</th>
<th>Единица измерения</th>
<th>Описание</th>
<th>Цена самовывоза</th>
<th>Цена с доставкой</th>
</tr>
{{range .Rows}}
<tr>
<td>{{.ProductID}}</td>
<td>{{.ProductType.NameType}}</td>
<td>{{.ProductName}}</td>
<td>{{.Weight}}</td>
<td>{{.Unit}}</td>
<td>{{.Description}}</td>
<td>{{.PricePickup}}</td>
<td>{{.PriceDelivery}}</td>
</tr>
{{end}}
</table>
<script>
function addProduct() {
// Получение данных из формы
var form = document.getElementById("addProductForm");
var formData = new FormData(form);
// Отправка данных на сервер
fetch("/add_product", {
method: "POST",
body: formData,
})
.then(response => response.json())
.then(data => {
// Обработка ответа от сервера
console.log("Product created:", data);
// Очистка формы или выполнение других действий при необходимости
form.reset();
})
.catch(error => console.error("Error:", error));
}
</script>
</body>
</html>
尽管这部分代码与表输出完美地结合在一起，
{{range .Rows}}
<tr>
<td>{{.ProductID}}</td>
<td>{{.ProductType.NameType}}</td>
<td>{{.ProductName}}</td>
<td>{{.Weight}}</td>
<td>{{.Unit}}</td>
<td>{{.Description}}</td>
<td>{{.PricePickup}}</td>
<td>{{.PriceDelivery}}</td>
</tr>
{{end}}
我想从表示这种 struct 的表中获取数据本身
package product_types
type ProductTypes struct {
IDType string `json:"type_id"`
NameType string `json:"type_name"`
}
当前代码的结果现在如下所示
我试着把它改成这个
<label for="typeSelect">Product Type:</label>
<select class="form-control" id="typeSelect" name="TypeID">
{{ range .Rows}}
<option value="{{.ProductType.IDType}}">{{ .ProductType.NameType }}</option>
{{ end }}
</select>
结果变得更好了，但最后还是出现了重复的情况
