I have a list view in my page with list of items on page load and I need to focus the list items in the list based on the user search in a text field on form submit..can any one help me with this?
You do not tell us what kind of HTML elements should be focused - normal divs/spans or form elements like inputs.
If you need to focus a normal element, i.e. to highlight it, then you just need to CSS decorate it. You can do this via:
listItem.add(AttributeModifier.append("style", "border: 1px red solid", ";"));
or
listItem.add(AttributeModifier.append("class", "myHighlightClass", " "));
The above will add CSS style or class attribute to the HTML element with wicket:id for the ListView.
If you need to focus an HTML input/select element then you need to execute JavaScript like $('#yourInputId').focus().
You can do it in Wicket's #renderHead(IHeaderResponse response) method:
response.render(OnDomReadyHeaderItem.forScript("$('#" + textField.getMarkupId() + "').focus()"));

I have a Typo3 server. On that I created some different content elements with mask.
In this elements there are often repeating content, like texts or other stuff.
So the editors make a new element in the backend, there they can add a headline and as much text parts as they want.
Often it looks like this:
Thats good, the editor can see a "preview" of the textparts. In this example "Karriere,Partner...". This naming happens automatically.
My Problem is, some times there arent any titles. Its always "No title". As an editor its quite hard to find the right dropdown to edit some stuff, you mostly have to open all dropdowns and search for the right one.
Its look then like this:
In both elements there are some string inputs that are very good for the title.
So my question is, how is mask gonna choose the title? Its not the first string input.
And secondly, can I tell Mask that they have to choose input field XYZ as title?
Heyo
Yes, you can tell Mask which field to use as a title for inline elements (like repeating contents). When you're setting up a new Mask element, right below the "Label" field of the repeated inline element, there is a field "Field that should be used as label for inline element (starting with tx_mask_)". This will be used as the title that is displayed in the backend. In the placeholder of that field, it explicitly says that "If empty, first field is used".
So, if your inline element has a field "my_awesome_header" which you would like to use as the title in the backend, set the above to "tx_mask_my_awesome_header".
I am not certain as to why it does not display anything in your second example. It might be that either the first input field is not a string, or the first input field is a string but it is empty.
I hope this helps. Let me know if you need further clarification.
Edit: Since that question came up, it should be possible to set a static default title to the containing Mask element using mod.wizards.newContentElement.wizardItems.mask.elements.[name of the mask element].tt_content_defValues.header = My awesome static title. As I said in the comments, though: I always give my Mask elements a header field and let editors fill that in.
I would like to print a GWT widget which extends Composite. This widget is composed of a grid whose cells are built with a ListDataProvider. When the user clic on a button print, the widget to print is built. Once this is done, I launch the print:
Element element = widgetToPrint.getElement();
String content = element.getInnerHTML();
print(content);
public static native boolean print(String content)
/*-{
var mywindow = window.open('', 'Printing', '');
mywindow.document.write('<html><head><title>Test</title>');
mywindow.document.write('<link rel="stylesheet" href="/public/stylesheets/ToPrintWidget.css" type="text/css" media="all"/></head><body>');
mywindow.document.write(content);
mywindow.document.write('</body></html>');
mywindow.print();
return true;
}-*/;
So, here is my problem:
The window which is opened by this method contains the core of the widget (built by the UI Binder), but some children are missing...
If I look inside the ListDataProvider and its related FlowPanel, the data are consistent, i.e. I've got several item in my list and in the flowPanel.
Consequently, it should be visible on the printing window...
I thought that maybe the problem was related to the method used to print the widget, so I also tried to add this widget into a dialogbox just before launching the print, to see if the widget was properly built... and it was.
So my widget displays well on a dialogbox, but if I try to give its innerHTML to the print method, by using getElement(), some widgets are missing... I've the feeling that the widgets which should have been built when the ListDataProvider changes are not properly set in the DOM... Somehow it works when I add the widget to a regular component, but it doesn't work when I have to give directly its innerHTML...
Do you have any idea ?
Thanks in advance.
Widgets are not just the sum of their elements, and DOM elements are not just the string that they are serialized to. Widgets are the element, and all events sunk to the dom to listen for any changes or interactions by the user. Elements then have callback functions or handlers they invoke when the user interacts with them.
By serializing the element (i.e. invoking getInnerHTML()), you are only reading out the structure of the dom, not the callbacks, and additionally not the styles set by CSS. This probably shouldn't be expected to work correctly, and as your experience is demonstrating, it doesn't.
As this is just a print window you are trying to create, event handling is probably not a concern. You just want the ability to see, but not interact with, the content that would be in that set of widgets. Styles are probably the main problem here then (though your question doesn't specify 'some children are missing' doesn't tell us what is missing, or give us any more clues as to why...) - you are adding one stylesheet in your JSNI code, but CellTable (which I assume you are using since you reference ListDataProvider) needs additional CssResource instances to appear correctly. I'm not sure how you can hijack those to draw in a new window.
Are you only using this to print content, not to let the user directly interact with the data? If so, consider another approach - use a SafeHtmlBuilder to create a giant, properly escaped string of content to draw in the new window.
String content = element.toString();
This will include all hierarchy elements in the node.
Just a reminder, all the GWT handlers will not work, and you have to sink all the events using DOM.
You might want to grab the outer HTML rather than the inner one.
GWT unfortunately has no getOuterHTML, but it's relatively easy to emulate.
If your widget is the only child within an element, then simply get the inner HTML of the parent element (w.getElement().getParentElement().getInnerHTML())
Otherwise, clone your widget's node add it to a newly created parent element, from which you'll be able to get the inner HTML:
DivElement temp = Document.get().createDivElement();
temp.appendChild(w.getElement().cloneNode(true));
return temp.getInnerHTML();
First thank you for your answers, it helped me to work out this problem.
I've almost solve the problem:
First, I do not use ListDataProvider anymore, because it wasn't clear for me when and how the view was refreshed. Instead I add my widgets by hand, which makes sense since, they are not going to move anyway.
Then, I define the style of my widgets using a common CSS stylesheet. However, in order to do it, I can't rely on CssResource, which was the way I was used to do it with GWT. I think that this comes from the JS method which gets lost by this kind of styles... Instead, I have to specify everything in a static CSS stylesheet, and to give it to the JS.
It works perfectly well, ie, I have my widgets, with thei styles, and I can print it.
But...
The color of some widgets depends on the color of the object that they represent. Consequently, I cannot write a generic CSS stylesheet... And as I said, I can't add a style using CssResource... Do you have any ideas on the way to handle that ?
To make sure I'm clear on the way I'm adding styles, here is an example:
Label l = new Label("Here is a cell in my grid to be printed");
l.addStyleName("PrintLineCell-kind_1");
With, in a public CSS stylesheet:
.PrintLineCell-kind_1{
background-color: red;
}
I hope there is a better way than to write 300 styles to cover 300 different colors...
My buttons are input type=button, id field set, and no text in between the tags since it appears to the right of my buttons rather than inside. (sorry, won't let me publish the html for some reason).
I .button() them and set their label. All works as expected, but I can't select them by :contains().
How do you select jQuery UI buttons by their labels?
Thanks in advance!
Edit
I don't select by id because the text of the button changes based upon a variable in my db. Is there a way to select by .data?
You should create a button and look how jQuery creates it. When you look at the example in the documentation you see that .button() creates a span element in the button element that contains the label. So you can query on this inner span element which has a class of ui-button-text.
But I think that you should overthink your code and rework it so that you can select on the ID since they are made to identify things.
Edit: Then go for the first advice
var buttons = $('button').filter(function (index) {
$('.ui-button-text:contains("' + your_string + '")', this).length > 0
});
As the title states: Will focus still be set on form controls with autofocus="autofocus" even if they are hidden with display: none; or visibility: hidden;?
If your question is whether a hidden field can steal autofocus from a visible one, the answer is no.
Hidden fields with an autofocus property get focus when they are made visible.
Here's a jsFiddle that shows what happens if you have a visible field and a hidden field, then show the hidden field.
And here's a variation that demonstrates what happens if the visible field does not have an autofocus property.
The HTML5 draft standard only requires that an element be "focusable" where focusable means:
An element is focusable if the user agent's default behavior allows it
to be focusable or if the element is specially focusable, but only if
the element is either being rendered or is a descendant of a canvas
element that represents embedded content.
User agents should make the following elements focusable, unless platform conventions dictate otherwise:
a elements that have an href attribute
link elements that have an href attribute
button elements that are not disabled
input elements whose type attribute are not in the Hidden state and that are not disabled
select elements that are not disabled
textarea elements that are not disabled
command elements that do not have a disabled attribute
Elements with a draggable attribute set, if that would enable the user agent to allow the user to begin a drag operations for those
elements without the use of a pointing device
Editing hosts
Browsing context containers
It does say "but only if the element is either being rendered..." and the standard defines "rendered" as:
An element is being rendered if it is in a Document, either its parent
node is itself being rendered or it is the Document node, and it is
not explicitly excluded from the rendering using either:
the CSS 'display' property's 'none' value, or
the 'visibility' property's 'collapse' value unless it is being treated as equivalent to the 'hidden' value, or
some equivalent in other styling languages.
Just being off-screen does not mean the element is not being rendered. The presence of the hidden attribute normally means the
element is not being rendered, though this might be overridden by the
style sheets.
User agents that do not honor author-level CSS style sheets are nonetheless expected to act as if they applied the CSS rules given in
these sections in a manner consistent with this specification and the
relevant CSS and Unicode specifications.
In short, the answer appears to be that if all other requirements are met then display:none won't be focused but display:hidden will - Assuming all browsers actually follow the spec.
I have the three following lines and the first two line gets all the images on the document and hides all, but then when I add the third line shows all the images.
What I need its to hide only the images with the attribute alt=minimize and alt=maximize but for some reason hides all the images.
$('img').attr('alt', 'minimize').css("display","none");
$('img').attr('alt', 'maximize').css("display","none");
$('img').attr('alt', 'logo').css("display","inline");
I am using IE7, but it should be compatible with IE6 and IE8.
Any help would be very much appreciated.
Thanks.
I'm thinking you are not using the attr function correctly, might you be looking for the attribute equals selector?:
$('img[alt=minimize]').css("display","none");
What you did with your code was,
Select all images
Change their alt attribute to 'minimize'
Hide them
Select all images
Change their alt attribute to 'maximize'
Hide them
Select all images
Change their alt attribute to 'logo'
Hide them
what you do: you take every img in document and set alt to logo and then set display: inline;.
Note, that attr('alt',string) doesn't filter all images to those with alt=string, but rather sets alt attribute to string on all images.
What you want to use is this:
$('img[alt="minimize"]').css...
$('img[alt="maximize"]').css...
$('img[alt="logo"]').css...
In the call $('img').attr('alt', 'logo').css("display","inline"); the "attr" doesen't filter the set of dom elements You catch with $("img").
If you want to hide everithing but not the image with the attribute 'alt' = 'logo' I think You can:
give it an Id of logo and then calling: $("img").not("#logo").hide()
from the jquery website:
hide():
The matched elements will be hidden
immediately, with no animation. This
is roughly equivalent to calling
.css('display', 'none'), except that
the value of the display property is
saved in jQuery's data cache so that
display can later be restored to its
initial value. If an element has a
display value of inline, then is
hidden and shown, it will once again
be displayed inline.
and
attr( attributeName )
Returns: String
Description: Get the value of an
attribute for the first element in the
set of matched elements.
If instead you want to hide all the maximize and minimize images (both share the "imize" part of the attribute):
$(parentElement).find("img[#attr $= '*imize']").hide()
OP is referring to
http://dev.w3.org/csswg/css3-values/#attr
alt I think is simply a string type, not "logo" whatever that is, that is not a data type.
try that. in fact, you can look up alt in the html5 img
http://www.w3.org/TR/html5/the-img-element.html#the-img-element
http://www.w3.org/TR/html5/the-img-element.html#attr-img-alt
http://www.w3.org/TR/html5/the-img-element.html#alt
(in order of reference clicking, last one is the target)
even if this isn't the exact answer (it should be), it should be a step in the right direction.
I am actually trying myself to figure out how to reference a css property within css with attr() - it's mentioned within the top URL. if I had my druthers, I could be using css calc() along with it, but that's draft. maybe I can get it to work...
