[英]If else condition for button, Grails
I'm looking for controller codes in Grails for buttons if/else. 我正在Grails中寻找控制器代码(如果/其他)。
I've got the codes for radio button, when the user selects : 当用户选择时,我已经有了单选按钮的代码:
<g:radio name="myGroup" value ="input2" />
if (request.getParameter("myGroup").equals("input1"))
{
println("asdasdasdasdasdhelloipass")
redirect (action: radio)
}
This is how it works, but for buttons, what is the if condition for it when the user click on the button. 它是这样工作的,但是对于按钮,当用户单击按钮时,if条件是什么? Thanks in advance.
提前致谢。
<g:actionSubmit value="Submit" action="abc"/>
What is it that you're trying to do? 您想做什么? The "actionSubmit" tag will submit the form parameters to an action called "abc".
“ actionSubmit”标签会将表单参数提交给名为“ abc”的操作。
class SomeController {
def index() { }
def abc() {
log.debug("called abc")
}
}
some/index.gsp 一些/ index.gsp
<html>
<head>
</head>
<body>
<g:form>
<g:actionSubmit value="blah" action="abc"/>
</g:form>
</body>
</html>
