[英]Why form submit opens new window/tab?
I found a lot of questions "How to open form result in new window" , but I'm facing opposite problem. 我发现了很多问题“如何在新窗口中打开表单结果” ,但我面临着相反的问题。
I have form: 我有形式:
<form:form method="post" commandName="search">
...
<input type="submit" value="Search" />
</form>
Then I have controller with handling method 然后我有控制器与处理方法
@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";
}
Everything works fine, except the fact that result is opened in new window/tab. 一切正常,除了在新窗口/选项卡中打开结果的事实。
Solution that I found and is working is to add target attribute: 我找到并正在解决的解决方案是添加目标属性:
<form:form method="post" commandName="search" target="_self">
But _self
is default AFAIK. 但是
_self
是默认的AFAIK。
I'm wondering why is that happening. 我想知道为什么会这样。
I checked generated HTML and it seems to me ok: 我检查生成的HTML,在我看来好吧:
<form id="search" action="/myApp/A/search.form" method="post">
