使用form:input为Spring MVC编写表单的正确方法是什么 [英] What's the correct way to write a form for Spring MVC with form:input
问题描述
我想在Spring MVC中编写一个表单，并始终使用form:input
I want to write a form in Spring MVC and use form:input consistently
<form:form method="post" action="/insertChapter" modelAttribute="Chapter">
<form:input type="hidden" path="chapter" value="${info.chapter}"/>
<form:input path="title" />
<form:input type="submit" value="Insert" />
</form:form>
控制器:
@RequestMapping("/insertChapter")
public String insertChapter(@ModelAttribute Chapter chapter) {
if (chapter != null)
infoService.insertChapter(chapter.getChapter(), chapter.getChapter());
return "redirect:/getInfoListList";
}
但是服务器抱怨:
infoListList.jsp(行:83，列:7)根据TLD或标签文件，标签输入必须使用属性路径
infoListList.jsp (line: 83, column: 7) According to the TLD or the tag file, attribute path is mandatory for tag input
第83行是以下形式:input type ="submit" ...
line 83 is the one with form:input type = "submit"...
那么编写此jsp表单的正确方法是什么?我知道如何用没有form:input的形式写东西. form:input和just input有什么区别?混用form:input和just input(用于提交按钮)是否被认为是一种好的样式?
So what is the correct way to write this jsp form? I know how to write with form without form:input. What is the difference between form:input and just input? Is it considered a good style to mix form:input and just input (for submit button)?
推荐答案
您不能使用"form:input"标签提交表单. 要提交表单，您应该使用"form:button"标签 否则，您可以将type ="submit"用作html"input"标签.
you cannot use "form:input" tag to submit form. To submit the form you should use "form:button" tag or else you can use html "input" tag with type="submit".
<body>
<form:form modelAttribute="pizza" action="add" method="POST">
Pizza name:<form:input path="name" />
<br>
<br>
Pizza price:<form:input path="price" />
<br>
<br>
Select Base<form:select id="baseList" path="base" items="${baseList}"
itemLabel="name" itemValue="baseId"></form:select>
<br>
<br>
Select Toppings
<form:checkboxes items="${toppingList}" itemLabel="name"
itemValue="toppingId" path="toppings" />
<form:button>Submit</form:button>
</form:form>
