为什么表单提交会打开新窗口/标签? [英] Why form submit opens new window/tab?
问题描述
我发现了很多问题如何在新窗口中打开表单结果,但是我面临着相反的问题。
I found a lot of questions "How to open form result in new window", but I'm facing opposite problem.
我有表格:
<form:form method="post" commandName="search">
...
<input type="submit" value="Search" />
</form>
然后我有控制器处理方法
Then I have controller with handling method
@RequestMapping(value = "/search.form", method = RequestMethod.POST)
public String submit( @Valid final SearchObject searchObject, final BindingResult bindingResult ) {
if ( bindingResult.hasErrors() ) return "forms/search";
return "redirect:/A/result.form";
}
一切正常,除了在新窗口/标签中打开结果的事实。
Everything works fine, except the fact that result is opened in new window/tab.
我发现并且正在工作的解决方案是添加目标属性:
Solution that I found and is working is to add target attribute:
<form:form method="post" commandName="search" target="_self">
但是 _self
是默认的AFAIK。
But _self
is default AFAIK.
我想知道为什么会发生这种情况。
I'm wondering why is that happening.
我检查生成的HTML并且在我看来好了:
I checked generated HTML and it seems to me ok:
<form id="search" action="/myApp/A/search.form" method="post">

编辑2 为结果添加方法.form
edit 2 added method for result.form
@RequestMapping(value = "/result.form", method = RequestMethod.GET)
public String result() {
return "forms/result";
}
我的控制器类以:
@Controller
@RequestMapping(value = "/A")
public class AController {
推荐答案
问题出在基本标记。我故意在标签中 target =_ blank
,可能是因为我从w3schools复制了这个例子: - /
Problem was in base tag. I had intentionally target="_blank"
in tag, probably because I copied the example from w3schools :-/
