Form submit doesn't work for the second time, if nothing was changed. It is not possible to make a search in a little while with the same filters. I've added a random number in the URL to resolve this. But this is bad for google analitics, now they notice them as different links.
Resolved. The problem was due to the anchor in the form action:
<form action="/search#anchor">
...
This is the corrected form action
<form action="/search">
Thanks to all.

Actually its not actually a problem, but I'm thinking and searching for it for a while.
When we use php and to setup some link we can use something like-
some link
in this way anyone can see what is going on by looking at the url. Is there any possible way to keep it hidden like the POST method of the form element?
I don't want user to modify and play around with my parameters and values. Lets guess I don't want to encrypt the values and parameters and I can't use form element as they should be pure links. And also what if I don't want to use url rewriting engine.
Any ideas from the experts?
edit:
I forgot to mention another most important thing that I need to get the parameters and the values I want to pass through that link and do some stuffs in the page i'm linking to.
thanks again.
You can use a hidden form
<form action="realurl" method="post">
<input type="hidden" name="parameter" value="value1"></input>
</form>
<a onclick="forms[0].submit();" href="http://fake">link text</a>
I'm trying to troubleshoot a bug in my application. I have a form on a page with two fields: a textbox and a checkbox. I'm submitting this form via ajax using :remote => true and displaying the results on the page.
In some cases - even though the checkbox is checked - the console log shows the value as empty.
It looks as though this happens consistently after the first time the form is submitted.
I'm having a hard time tracking down why this could be happening.
Any ideas on where to start investigating would be much appreciated.
I think I sorted this out. On the create.js.erb I was setting the attribute of the checkbox to not checked. I was doing this to reset the form instead of $('#someid > form')[0].reset(); I just changed that out and it seems to be working as expected on each subsequent post.
Im very new to grails (1.3.7) so please be patient :-)
I have a gsp where I have various checkboxes. A user can click on them and then send his answer to a controller. The controller is receiving this request correctly.
My problem is, that, for working with what the user chose, I have to check every parameter - to see if this checkbox was really checked. Thats really cumbersome and doesnt work very well, because the page displaying the checkboxes is dynamic - so the checkboxes which can be clicked are dynamic too. In my controller I dont know for which params I have to check then.
Is there any possibility to receive a list of all checkboxes (or better: all checked checkboxes) in my controller? I researched but didnt find an answer!
Thanks for answering! :-)
[EDIT]
Thank you,
params.name.each{i->
System.out.println(i);
}
is very simple and works :-) It just gives back the checked ones
It must be passed as an extra request parameter (it's a limitation of http). You can add following field into your form, for example:
<input type="hidden" name="checkboxes" value="${myCheckboxesNames.join(',')}"/>
or making same using JavaScript, as it names are dynamic on client side.
BTW, you can also check all request parameters, by
params.each { name, value ->
// so something
}
so if you are using some special prefix/suffix for this checkbox names, it would be:
params.entrySet().findAll {
it.key.startsWith(prefix)
}.each {
println "Checkbox $it.key = $it.value"
}
I have a problem in IE. Hitting enter when the focus is on the last input control sends the focus to the "Next" button. This submits the form. So far, so good.
The code in my base class WizardController looks to see if the Next submit button is null, as follows:
protected string NextButton
{
get
{
return ControllerContext.HttpContext.Request.Params["NextButton"];Nex
}
}
However, despite the form submitting, this property returns null unless the user explicitly clicks on the button with his mouse.
This is blatantly wrong, but I have no idea why it is happening.
EDITED TO SPECIFY THE PRECISE PROBLEM:
The problem only occurs IF there is ONLY one TEXT input control in the HTML form that gets rendered to the browser.
END EDIT

I have finally found an explanation for my problem:
It seems to be a bug in IE, whereby if there is a single text input in the rendered HTML form, then IE will not submit the form properly. The issue is described (briefly) at:
Form Submit via Enter Key when using IE
In the above link, no description is given as to why the bug occurs, or since what version of IE, so a blanket solution is better.
The workaround suggested in the article is to add a css hidden text input (with conditionals for IE):
<!--[if IE]>
<input type="text" style="display: none;" disabled="disabled" size="1" />
<![endif]-->
This worked for me, so issue solved.
The following is included to document the issue as I experienced it:
Unlike the problem described in the article, my form did submit. However, when I tried to check which button had been accessed by hitting tab or enter key, no submit button was in the HttpContext.Request.Params collection. So the behaviour I saw was slightly different.
What the above article did identify is that this behaviour is only seen WHEN there is ONLY one text input control. A single check box, for example, does not cause the problem.
I hope that this documents the problem adequately... and that MS will one day correct the bug.
A simple work around might be to use a hidden form element and depend on that rather than the button.
<input type='hidden' name='action' value='next' />
If you have multiple buttons you can always use JavaScript to change the value of the action element just before submitting.
I'm building a grid in ASP.NET MVC and I have the following issue:
Above the grid i have a column selector which lets people customize the columns being shown. This is a form with a submit button so that people can add/remove multiple columns at once without going trough multiple postbacks.
Below the grid I have paging. This is paging trough actionlinks (a href's).
alt text http://thomasstock.net/mvcget.jpg
What happens when a user add/removes columns is that the form gets submitted to http://localhost:56156/?columnsToDisplay=EmployeeId and ofcourse the grid jumps back to page 1. I'd like to keep the grid on the page the user was currently on. So I need a way to include the current querystring parameters into the form's action attribute.
The other way around too: I need a way to do the same with actionlinks. But this is less necessary as I could always replace the a href's with buttons and put them in a form. But I'd rather not do that.
I'm looking for a solution without javascript! I can do it myself in javascript, but I'd like my grid to work perfectly on javascript-disabled browsers.
Any help is appreciated.
Edit:
Oh yeah, to make it a bit harder, I'm also looking for a solution without cookies/session variables. :-)
You need to add the line below into your column selector form
<input type="hidden" name="page" value="<%=Request.QueryString["page"]%>" />
