Struts tag <s:submit> 有什么区别?和 Struts jQuery 标签 <sj:submit>? [英] What's the difference between Struts tag <s:submit> and Struts jQuery tag <sj:submit>?
问题描述
Struts 标签 <s:submit> 和 Struts jQuery 标签 <sj:submit> 都以相同的方式提交.我的意思是，他们刷新页面并转发到另一个页面.但我认为 Struts jQuery 标签实现了 Ajax，所以页面在提交时不应该改变.我说的对吗?
Struts tag <s:submit> and Struts jQuery tag <sj:submit> both submit in the same way. I mean, they refresh the page and forward to another to page. But I thought Struts jQuery tag implemented Ajax so the page should not be change while submitting. Am I correct?
我已经在表单中实现了两个标签，同时提交两者的工作方式相同.
I have implemented both tags in form, while submitting both are working same way.
<s:form action="part!list" >
<s:submit action="part" method="list" />
</s:form>
<s:form action="part!list" >
<sj:submit />
</s:form>
如果我使用 <sj:submit> 它可以工作，但是我添加了一些 struts 标记按钮 <s:submit> 以相同的形式然后它没有不工作.那么，Struts 标签就不行了?
If I use <sj:submit> it works, but I add some struts tag button <s:submit> in the same form then it doesn't work. So, Struts tag won't work?
推荐答案
你可能忘记在 <head> 的正文中包含 <sj:head/> 标签;.此标记将 JQuery stylesheet 链接到页面和其他初始内容，没有它就不会进行 Ajax 调用.查看正确提交 SubmitTag 的示例.
You have probably forgot to include <sj:head/> tag in the body of the <head>. This tag links JQuery stylesheet onto the page and other initial things, without it Ajax call is not made. See examples of correct submitting SubmitTag.
如果您通过 <sj:submit> 进行 Ajax 调用，页面不应刷新，但 targets 可能会在成功结果后更新.如果页面头部没有包含 JQuery，我认为表单不会发出任何 HTTP 请求，它的行为就像你没有包含 action 属性一样.
If you make an Ajax call via <sj:submit> the page should not refresh but the targets could be updated on successful result. If didn't include JQuery in the head of the page I don't think the form make any of the HTTP requests, it's behaving like you are not included the action attribute.
