[英]Get value from combobox in spring
我正在努力尋找一種在Spring中接收選定組合框值的方法。
這是html形式:
<form method="post" multiple="true">
Authhor: <label th:text="*{ownerName}" /><br />
Title: <label th:text="*{name}" /><br />
Description: <label th:text="*{description}" /><br />
Price: €<label th:text="*{price}" /><br />
Product: <select th:field="${productss}" th:remove="all-but-first">
<option th:each="product : ${productss}"
th:value="${product.id}" th:text="${product.name + ' (+ €' + product.price + ')'}">Productname</option>
</select><br />
<img width="250" heigth="250" th:src="*{plainURL}"/><br />
<button align="right" class="btn" type="submit" name="add" ><span class="glyphicon glyphicon-check">Add to shopping cart</span></button><br />
</form>
單擊按鈕后,該方法在控制器中執行:
@RequestMapping(value = IMAGE_ID, method = RequestMethod.POST, params = {"add"})
public String add(@PathVariable("id") int id, HttpSession session, Model model) {
...
return "redirect:/cart";
}
我該如何從組合框中接收所選值?
像這樣更改您的選擇元素:
<select th:field="${productss}" th:remove="all-but-first" name="product" >
<option th:each="product : ${productss}"
th:value="${product.id}" th:text="${product.name + ' (+ €' + product.price + ')'}">Productname</option>
</select><br />
並添加控制器@RequestParam
:
@RequestMapping(value = IMAGE_ID, method = RequestMethod.POST, params = {"add"})
public String add(@PathVariable("id") int id,@RequestParam Integer product, HttpSession session, Model model) {
...
return "redirect:/cart";
}
