Good morning!
I need to post a form, I've already changed all the values inside that form (drop-drown list, text fields , check-boxes, etc), in this way:
final HtmlPage page4 = webClient.getPage("somepagemakinmemad");
HtmlForm formx= page4.getFormByName("lista_grupos");
changing values like:
HtmlSelect duracion = (HtmlSelect) page4.getElementByName("p_duracion_"+datum.getCrn()+"_1");
HtmlOption option1 = duracion.getOptionByValue("0029_029");
duracion.setSelectedAttribute(option1, true);
That is, I am changing the values through obtaining the html element from the page, not through the form (is that okay anyway?).
And then I try to submit the form, through:
<input id="p_guardar" class="boton" type="button" onclick="validaAPG()" value="Guardar">
Which is the "button-like" input where someone clicks when is over with the form.
I have to say, when I print the html code of the form, with "asXml()", I see the form the with selected values I've intended to select.
Question: How can I click on that button and send the form? That input runs a script, when clicked
Thanks everyone, let me know if you need any other kind of info.
You can use below code to click on the button to submit the form.
HtmlButtonInput button = (HtmlButtonInput)page.getElementById("p_guardar");
page = button.click();
You dnt need to care what script runs when clicked.If you dont need to run the script remove the attribute.

OK, so first off, let's start with me acknowledging that the bind( ... ) way of binding Lift forms is so last week! :) I do know that, and I just haven't gone back to update this code yet. Also, I trust now that there's some really slick Lifty way to do this. That's what I seek. I'm stumped as to even how to hack something together. That said...
I have a list of Items that I initially display non-editable, and the title of each Item is an ajax-enabled link that calls to the server and replaces that line-item with an editable form of the Item (I use SetHtml to swap the form in at the < li> that listed that Item).
"parent" Items List view looks something like this
< form data-lift="form.ajax">
< div data-lift="creategamewizard?multipart=true" id="wizardform">
< ul>
< li>Item 1< /li>
< li>Item 2< /li>
< /ul>
some more form elements
< button>Submit< /button>
< input type="hidden" id='298356928734' />
< /div>
< form>
This ajax submit (via the hidden field) calls processSubmit().
The SetHtml that swaps in the editableItem form looks something like this.
NOTE: At the end of the following listing, the "save" binding has no server-side code tied to it because the "parent" submit button is already on the page, and when I put another hidden field in this binding or tried to tie any code directly to the Edit Item Save button, that code and the "parent" submit got triggered. So the approach below was to try to use the "parent" submit for both the parent submit as well as the Edit Item submit.
<a href="javascript://" onclick={ajaxOnClickHandler(editItemClickHandler(item.id.get))}>{item.title.get}</a>
def ajaxOnClickHandler(jsHandler: ()=>JsCmd) =
{
SHtml.onEvent( e => jsHandler()).toJsCmd+";return false;"
}
def editItemClickHandler(itemId: String): ()=>JsCmd = ()=>
{
trace.logAjaxComm("ExistingItem.Edit()")
JsCmds.SetHtml("LiId"+itemId, getEditableItem(promo) )
}
def getEditableItem(itemId) =
{
bind( ...
"promotitle" -> SHtml.text(editablePromo.get.promotitle.is,
(s:String) => {
trace.logUIDataManipulation("Saving new promo Title["+s+"]");
editablePromo.get.promotitle(s)
}, "id" -> "promotitle"),
"save" -> SHtml.button("Save", ()=> {})
)
}
Then when the user selects an Item, and the editable Item form is plugged in, there's "another" submit button that should ajax submit the form data for that item, and then swap back in the (now updated) nonEditable version of the data.
The problem for me is the submission. In addition to the Edit Item form above, I've got a ajaxified submit button on the "parent" non-editable list page to handle submitting some fields below the list. The Edit Item "save"-> binding adds a button, which should do (and in fact does) nothing for itself, but it does trigger the "Parent" submit button. And I route that submit to do the save of the Edit Item form.
The non-editable Item and the editable item code swaps fine, but changes made in the editable Item form is not saved, and I figured out that that was happening because the elements in the editable Item form are not being submitted at all, following is an example of a log message I don't see at all...
bind( ... "promotitle" -> SHtml.text(editablePromo.get.promotitle.is,
(s:String) => {
trace.logUIDataManipulation("Saving new promo Title["+s+"]");
editablePromo.get.promotitle(s)
}, "id" -> "promotitle")
)
In a normal ajaxified form, all element handlers are called (if there are changes to the field, I guess...) in order of rendering, with the submit/hidden elements' handlers being called last (if they're last in the bind list.
so finally, let's get around to my question:
if you're doing in-place editing like this, how do I manage 2 submit buttons (the one for the non-editable list page plus the additional one that gets added when editing an item)?
I'm sure I don't need to refresh the page, but I can't figure out how you'd do this with Ajax.
Maybe alternatively, the in-place editable form can be submitted as a non-submit ajax action, ie. somehow that doesn't trigger the parent submit?
For anyone tripping over this question, I figured I'd share the solution I eventually found...
1)The problem was that the submit (for AJAX this is the hidden html tag) happened before the editable Item's field handlers were called. So when the AJAX update that collapsed the editable Item back into just a non-Editable list item, the data hadn't yet been updated. So what was displayed in non-editable form didn't show the update, yet if I refreshed the page in the browser, the update had been saved to the database and now showed properly.
2)The reason for the mal-ordering is that Lift assigns each form tag's server-side handler an id (which are "monotonically increasing" with an additional string added to the end). That's fine until you do an ajax live-update of a form and add fields (as I did when I inserted the Editable Item fields). These newly-added fields were assigned server-side ids that came after the hidden field that got generated as part of the initial page rendering.
3)The solution was to explicitly shove the hidden field into a much higher id using S.formGroup. See here for more details...
The example from the last link below is as follows (and differs from mine in that it uses SHtml.submit, whereas I use SHtml.hidden). It adds the constant 1,000 to the submit button's server-side handler id:
"type=submit" #> S.formGroup(1000) {
SHtml.submit("Submit", process)
}

I have two form in the same Tapestry page's:
First one is composed of :
select
submit button.
If there is a valid result I display it.
Otherwise I want to display the 2nd form wich is composed of :
4 textfields
1 submit button
So the 2nd must not be displayed first time, but only in case of empty result from the 1st one.
First off: Please share what you have tried so far.
Second: You can do this in a number of ways. The easiest is just to use a
<form>
<t:if test="showFirstForm">
....your 1st form content ....
<p:else>
....your 2nd form content ....
<p:else>
</t:if>
</form>
You might also like to have a look at the FormFragment for ajax controlled dynamic form content using triggers to redraw.
I'm creating a PDF form with a submission button. I would like the form to email based on the value of another form in the field. I'm assuming I need to do an "IF...ELSE" statement, but keep getting a syntax error that I cannot figure out. I am completely java illiterate.
This can be done using multiple solutions, but you do need to program Javascript inside of the PDF. You can use if-else on-click of the email-button. Here you can check values entered inside of the PDF form:
if (this.getValue("somefield") == "left") { emailvalue = "toA#domain.com" } else { emailvalue = "toB#domain.com" }
But you could also set the value onBlur or onFocus of a certain field. Like with radio-buttons the onBlur is useful because you know the user clicked or focused on this field and so set the variable emailvalue to a certain value.
A form populates and the OnLoad event tests for the value in a field. If that value is blank, then I want a hyperlink to appear in place of the textbox which I have figured out. The hyperlink needs to link to another form within the database which is my question.
Take the following snippit:
If cp = "" Then
Forms[!MyForm]![MyTextControl] = "Update"
Forms[!MyForm]![MyTextControl].IsHyperlink = True
' what is the code to add the link to the other form
Else
Forms[!MyForm]![MyTextControl] = cp
End If
Any thoughts on how to create a hyperlink that links to another form?
The text for a hyperlink in a textbox is:
="Form##form table1_form#This will open a form#"
="Display text#Address if required#sub address, eg form or report#screen tip#"
I wanted to find a way to upload a single file*, in the background, have it start automatically after file selection, and not require a flash uploader, so I am trying to use two great mechanisms (jQuery.Form and JQuery MultiFile) together. I haven't succeeded, but I'm pretty sure it's because I'm missing something fundamental.
Just using MultiFile, I define the form as follows...
<form id="photoForm" action="image.php" method="post" enctype="multipart/form-data">
The file input button is defined as...
<input id="photoButton" "name="sourceFile" class="photoButton max-1 accept-jpg" type="file">
And the Javascript is...
$('#photoButton').MultiFile({
afterFileSelect: function(){
document.getElementById("photoForm").submit();
}
});
This works perfectly. As soon as the user selects a single file, MultiFile submits the form to the server.
If instead of using MultiFile, as shown above, let's say I include a Submit button along with the JQuery Form plugin defined as follows...
var options = {
success: respondToUpload
};
$('#photoForm').ajaxForm(options);
... this also works perfectly. When the Submit button is clicked, the form is uploaded in the background.
What I don't know how to do is get these two to work together. If I use Javascript to submit the form (as shown in the MultiFile example above), the form is submitted but the JQuery.Form function is not called, so the form does not get submitted in the background.
I thought that maybe I needed to change the form registration as follows...
$('#photoForm').submit(function() {
$('#photoForm').ajaxForm(options);
});
...but that didn't solve the problem. The same is true when I tried .ajaxSubmit instead of .ajaxForm.
What am I missing?
BTW: I know it might sound strange to use MultiFile for single-file uploads, but the idea is that the number of files will be dynamic based on the user's account. So, I'm starting with one but the number changes depending on conditions.
The answer turns out to be embarrassingly simple.
Instead of programmatically submitting using...
document.getElementById("photoForm").submit();
... I used...
$("#photoForm").submit();
Also, since I only need to upload multiple files on occasion, I used a simpler technique...
1) The form is the same as my original...
<form id="photoForm" action="image.php" method="post" enctype="multipart/form-data">
2) The file input field is basically the same...
<input id="photoFile" "name="sourceFile" style="cursor:pointer;" type="file">
3) If the file input field changes, submit is executed...
$("#photoFile").change(function() {
$("#photoForm").submit();
});
4) The AjaxForm listener does its thing...
var options = {
success: respondToUpload
};
$('#photoForm').ajaxForm(options);
