Is there a way to get wicket component by its output markupid? I have ajax function to send two markupId-s and I want to get two components that printed these id-s.
A MarkupContainer has an Iterator with his children. Components have a method getMarkupId(). You could iterate over this iterator and check if a children a has the desired markup id.

I have a simple form that's in a dialog fragment used to submitting two fields for log-in auth.
For simplicity I was hoping to not have to use data binding, but rather use some method to gather all data inside my sap.ui.layout.form.SimpleForm.
I added a name property to each input element which says in the docs it is " Defines the name of the control for the purposes of form submission."
https://openui5.hana.ondemand.com/#/api/sap.m.InputBase/controlProperties#name
However hard as I try to find there doesn't seem to be any getFormData methods.
All SO questions and guides either use data binding to a model, or hard-code references to the individual input controls with .getValue() methods.
And looking further into the form API, there doesn't seem to be a Submit event either.
Given an arbitrary form, what would be the best way to gather all submission values without hard-coded references or data-binding?
Would a method that walks though all the children elements of a form looking for all submission values work? I think it might, but there are more submission input types then just the input component.
You can get the value of the fields by directly using;
var oField = sap.ui.getCore().byId('IdOfTheFieldAtTheDialog');
var sValue = oField.getValue();
But it's always better and convenient to use data binding which keep things neat.
And If I assume that you have the id of parent form container, you can iterate over the items and get the sap.m.Input elements in it without knowing the IDs of the individual inputs, and you may check the name property of the fields if you want. Check this snippet;

I have created a extjs form which is divided into 2 parts using column layout and have almost 10-15 input elements in it. How can i disable all these input elements at a time depending on a condition. Currently i have created a function which fetchs all the components in a form and using ext.each loop through each element to disable them
Here is the function that i use
function prepare_form_view(form){
var f=Ext.getCmp(form);
var els=f.query('component');
Ext.each(els,function(o){
var xtype=o.getXType();
if(xtype=='textfield'||xtype=='combobox'||xtype=='datefield'||xtype=='textareafield'||xtype=='button'){
o.disabledCls='myDisabledClass';
o.disable();
}
});
}
Is there any alternative way so that I can disable all elements without looping through each and every elements. I want to use this function with other forms too. I looking for something like 'setFieldDefult' function.
If you are using FormPanel in ExtJs 4.x this is what you are looking for -
yourFormPanel.getForm().applyToFields({disabled:true});
The getForm() method returns the Ext.form.Basic object, with this class, you also could access to all the fields on this form with getFields(), then you could iterator all the fields to do anything.
Hope this helps and good luck:-)
What about panel's disable/enable method? This seems much easier.
panel.disable();
panel.enable();
Here is a suggestion.. Since, you say your form is divided into two parts why don't you put them in a FieldSet ? You can disable the fieldset as a whole with one method ie, setDisabled.
This will avoid the looping of components and disabling / enabling them one after the another.
You could use the cascade function of the form panel which is the ExtJs way to to do it but if you check the source code of the cascade function you will see that it uses a for loop also. The only benifit of using the cascade function is that it will work also for forms with nested panels. I think that your implementation will not work properly a case like that.
I'm trying to print a GWT widget as follows,
String html = DOM.getElementById("id").getInnerHTML();
Print.it(html);
I'm not getting the entire html content of the widget. So i'm not able to print the expected result.
Can you help me? Or tell me the alternative way of printing a particular GWT widget from the view.
Thanks in advance,
Gnik
Well, it should print the HTML code. Calling DOM statically may generate 2 problems for you:
The ID you are trying to use isn't the right one. There is another element with the same ID and you are retrieving the element for that ID.
The ID you are using doesn't exist, as a framework may be changing this ID.
You can try to retrieve the HTML code with this widget.asWidget().getElement().getInnerHTML();
That should give you the correct HTML representation of the widget.
And make sure you are calling those methods after the elements are loaded (onLoad()) into the document, or you may recieve a JavaScriptException due to the element being null (check here for more info).
I'm having a hard time testing our Wicket application using Selenium because of the random markup ids.
For individual elements, I can use abc.setOutputMarkupId(true).setMarkupId("myId")
to set their markup id explicitly.
But what if the element is added dynamically using a repeater (like ListView)? Is there a way to specify how the markup id sequence should look like?
Well, can't you do the same thing with ListView? If you make your own ListView implementation, and then in the populateItem(final ListItem<?> listItem) method, on that respective listItem you do:
listItem.setOutputMarkupId(true); // write id attribute of element to html
listItem.setMarkupId("id"+i);
where i is some index you initialize in the ListView's constructor or something?
as Andrei told that its possible but dangerous.
setMarkupId doc:
Retrieves id by which this component is represented within the markup. This is either the id attribute set explicitly via a call to
org.apache.wicket.Component.setMarkupId(java.lang.String), id
attribute defined in the markup, or an automatically generated id - in
that order. If no explicit id is set this function will generate an id
value that will be unique in the page. This is the preferred way as
there is no chance of id collision.

and also you cant get the markup id with getMarkupId()
I'm using an API that returns a JQuery Object which is a reference to a DIV container. I know my structure inside of the DIV container. I basically need to read some attributes from the first .
I've tried chaining the standard selectors off of my object but I get an error.
XML filter is applied to non-XML value ({selector:"div.panes > div.slice(0,1)", context:({}), 0:({}), length:1})
[Break on this error] var svideo = $(api.getCurrentPane()).('a').get(0);
Change your code to use .find() when you're going for descendant elements, like this for the DOM element reference directly:
$(api.getCurrentPane()).find('a').get(0)
//or..
$(api.getCurrentPane()).find('a')[0]
or if you want a jQuery object...
$(api.getCurrentPane()).find('a:first')
//or..
$(api.getCurrentPane()).find('a:eq(0)')
//or..
$(api.getCurrentPane()).find('a').eq(0)
