When i choose a date in my tag from the first page and i click one button to insert other datas, i am able to show the other inputs, but not the date, that return always in default viewing dd/nn/yyyy.
This is the <input> tag:
<input type="date" name="dteInizio" min="2000-01-01" max="2023-12-31" value="<%= beanCorso.getdataInizio()%>">
This is the Java code in the controller:
SimpleDateFormat sdfFormato = new SimpleDateFormat("yyyy-MM-dd");
try {
((Corso)oSessione.getAttribute("beanCorso")).setdataInizio(sdfFormato.parse(request.getParameter("dteInizio")));
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
When i run the code and i go to another page before save it, i can't see the entered date

I have three XHTML pages;
index.xhtml
page_1.xhtml
page_2.xhtml
In the index.xhtml page, I have a commandButton which sends the user to page_1.xhtml. All this is done in the navigation rule in faces-config.xml.
How would I redirect the user to page_2.xhtml from the index.xhtml using another commandButton assuming that both commandButtons' actions are linked to a backing Java class?
Just bind the buttons to different action methods which each return a different outcome.
<h:commandButton value="Go to page 1" action="#{bean.goToPage1}" />
<h:commandButton value="Go to page 2" action="#{bean.goToPage2}" />
with
public String goToPage1() {
// ...
return "page_1";
}
public String goToPage2() {
// ...
return "page_2";
}
Navigation cases are not necessary. JSF 2.0 supports implicit navigation. The navigation outcome can just be the path/filename of the desired target view. The file extension in the outcome is optional.
If you don't necessarily need to perform any business action on navigation, or you can do it in the (post)constructor of the backing bean of the target page instead, then you can also just put the outcome value in the action directly.
<h:commandButton value="Go to page 1" action="page_1" />
<h:commandButton value="Go to page 2" action="page_2" />
A <h:commandButton> will however not perform a redirect, but a forward. The enduser won't see the URL being changed in the browser address bar. The target page isn't bookmarkable. If you can, I'd suggest to use <h:button> instead.
<h:button value="Go to page 1" outcome="page_1" />
<h:button value="Go to page 2" outcome="page_2" />
Or if you really need to invoke a business action, but would like to perform a real redirect, then append faces-redirect=true as query string to the outcome value.
public String goToPage1() {
// ...
return "page_1?faces-redirect=true";
}
public String goToPage2() {
// ...
return "page_2?faces-redirect=true";
}

When should I use h:outputLink instead of h:commandLink?
You can also do this, in any part of your code to be redirected to "example.xhtml"
ExternalContext ec = FacesContext.getCurrentInstance()
.getExternalContext();
try {
ec.redirect(ec.getRequestContextPath()
+ "/faces/jsf/example.xhtml");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Add two navigation cases as shown below. In the action methods, return outcomes corresponding to the buttons.
<navigation-rule>
<from-view-id>index.html</from-view-id>
<navigation-case>
<from-outcome>page1</from-outcome>
<to-view-id>page_1.xhtml</to-view-id>
</navigation-case>
<navigation-case>
<from-outcome>page2</from-outcome>
<to-view-id>page_2.xhtml</to-view-id>
</navigation-case>
</navigation-rule>
Sorry if this sounds very obvious but I am new to Ionic 2 / Angular 2. Upon submitting a form, I need to update the button text and click event, ie:
first click on button = submit form + update button text to "Next"
second click on button = trigger goToNext()
I managed to update the button text but not update the click event (to goToNext() ).
.html
<form (ngSubmit)="logForm(i)">
<ion-item>
<ion-input type="text" [(ngModel)]="form.userinput[i]" name="userinput[i]"></ion-input>
</ion-item>
<button ion-button block type="submit" (click)="setNext($event.target, 'Next')">Check</button>
</form>
.ts
setNext(element, text){
element.textContent = 'Next';
}
goToNext(){
// go to Next Page
}
Ideally you change your design a bit to keep a variable that stores state of your 'Controller'. e.g. stores PageNumber. and then behave differently based on what page you are on. So I suggest change design a bit.
But to answer your current question without major change, you can bind the handler dynamically the same way you bind the text. then in the first handler, change the handler for the next click. the default values for handler and text will decide which one is going the be used initially
handler = this.setNext;
text = 'first text';
setNext(){
alert('handler1 called');
this.handler = this.goToNext;
this.text = 'other text';
}
goToNext(){
alert('second called');
// go to Next Page
}
and in your html you go like
<button ion-button block type="submit" (click)="handler()">{{text}}</button>
You can use n00b answer or something like this:
in html file:
<button ion-button block type="submit" (click)="check()">{{btn_txt}}</button>
in ts file:
btn_txt = 'Check';
check() {
if (this.btn_txt == 'Check') {
//do some logic
this.btn_txt = 'Next';
} else {
console.log('go to next page');
}
}
I am fairly new to Javascript and have a basic question. I have an HTML form with first_name and last_name input fields. I have the following Javascript code in the header but after the code runs, the focus goes to the next field (last_name). Why is that and how do I correct it?
Thank you.
<script>
function validateForm()
{
valid = true;
//validate first name
if (document.contactform.first_name.value == "")
{
//alert user first name is blank
alert("You must enter a first name");
document.getElementById("first_name").focus();
return false;
}
return valid;
}
</script>
and the form field code is:
input type="text" name="first_name" id="first_name" maxlength="50" size="30" onBlur="validateForm()"
A fix for this is to add a slight delay.. like so:
setTimeout(function() {
document.getElementById('first_name').focus()
}, 10);
Here is your example with this fix in jsfiddle: http://jsfiddle.net/FgHrg/1/
It seems to be a common Firefox problem.. I don't know exactly why but it has something to do with Firefox loading the javascript before the DOM is fully loaded.. in otherwords getElementById('first_name') returns null. But adding the slight delay fixes this problem.
Which signal does a GtkTreeView emit when an editable column is edited? I want to catch edits with a callback function.
I catch edits in my treeview with the following code (c++):
treeview.get_column_cell_renderer(col_index)->signal_editing_started().connect(
sigc::mem_fun(*this, &YourClass::onEditingStarted));
And the callback is:
void YourClass::onEditingStarted(Gtk::CellEditable* editable, const Glib::ustring& path) {
// here I'll connect an event to catch when the edition ends
// YourClass::onEditingEnded has no parameters
editable->signal_editing_done().connect(
sigc::mem_fun(*this, &YourClass::onEditingEnded));
}
On the web page, there is gridview control contains product ID's. bind to a link button.
