I'm selecting a single element called "detalleItemDescription" in Sencha Touch 2 like this:
this.getDetalleItem().down('#detalleItemDescription').setData(record.data);
how to select multiple?
this.getDetalleItem().down('#detalleItemDescription','#second','#third').setData(record.data);
Is that possible? how to do that?
Thanks!!
You can use Ext.ComponentQuery.query that accepts a comma separated list and will return an Composite collection you can enumerate upon.
Or you can use the query method directly on your object.
this.getDetalleItem().query('#detalleItemDescription','#second','#third').each(function(item) { item.setData(record.data) }) ;

I'm tasked with moving some UI-Grids to AG-Grid.
I need to allow the user to use a space delimited string for a column filter so "1 4 23 88" would return all rows where column has 1 or 4 or 23 or 88 as a value.
AG-Grid has the drop down OR option but is added clicks and only allows two values.
With UI-Grid the filter parameter in columnDefs can have a condition:
filter:{condition: filterFunction}
FilterFunction simply has the custom logic and returned true or false.
Is there something similar with AG-Grid? Reading through the docs it seems to get overly involved to create a custom filter. The UI-Grid solution is like 6 lines of code.
CentOS 7, VueJS
I ended up using:
filter:'agTextColumnFilter', filterParams: {textCustomComparator: this.filterFunction}
With filterFunction holding the logic.
https://www.ag-grid.com/javascript-grid/filter-text/#text-custom-comparator
Though I'm using a number column there is not a comparator filterParam for numbers, only 'comparator' for dates and 'textCustomComparator' for text.
This seems to work fine for what I need.
There exist any way in Vue.js to make a sum between two interpolation values inside an html tag?
ex:
value1= 5
value2= 3
<span> {{value1}} + {{value2}}</span>
So I would like to know if its posible to obtain a third value rendered on the span tag adding the two values.
<span>{{value1 + value2}}</span>
I see no reason to manipulate data with operations on the template in this case.
The best (and simple) way, probably is to sum that values in your js code and render the result at template as another data property.
Although there is a Vue magic trick that allows you to made that.
It is called Computed Properties. Where you will be 'listening' some dependent data to create another data.
I totally recomend that you read Computed Properties documentation and see how it works
Here is the link:
https://v2.vuejs.org/v2/guide/computed.html
:)
Inside the {{}} you can run any JS really, so you should make a method that handles adding the 2 variables and inside that method it can check that both are numbers and handle converting strings if needed. Or you could try to turn this logic into a computed property.
I am trying to build an XPath for a property that is constantly changing. The number prefix is bound to change sometimes.
Original:
//*[#id="MainContent_DXEditor3_I"]
which I can query using
$x('//*[#id="MainContent_DXEditor3_I"]
Intended use: I would like to build the string to handle any number in the sub-string. Example: if the property changes to 'MainContent_DXEditor33_I' or 'MainContent_DXEditor8_IXYZ' - I still want to be able to find the element without having to rebuild
You can try to relax the predicate by using starts-with() :
//*[#starts-with(#id, "MainContent_DXEditor")]
You should try to identify a unique parent of the element or save xpath as a string that contains a variable.
These are the 2 possible solutions.
A general selector will return multiple elements, if you identify a unique parent then you are closer and after that you can select any first, second.. last if you have a list.
I have seen this:
$makeModels = Make::model()->findAll(array("select"=>"fieldMake", "order"=>"fieldMake DESC"));
is it possible to do so with findAllByAttributes too? I need to only select one column values. I mean I don't want findAllByAttributes return array of object I need only an array of values.
If you only want an array of values use a custom SQL command with CDbCommand
Take a look at the following url for more information:
http://www.yiiframework.com/doc/api/1.1/CDbCommand
It will probably look something like this:
Yii::app()->db->createCommand('your sql query')->queryColumn();
In String Template one can easily get an element of a Java Map within the template.
Is it possible to get the n-th element of an array in a similar way?
According to the String Template Cheat Sheet you can easily get the first or second element:
You can combine operations to say things like first(rest(names)) to get second element.
but it doesn't seem possible to get the n-th element easily. I usually transform my list into a map with list indexes as keys and do something like
map.("25")
Is there some easier/more straightforward way?
Sorry, there is no mechanism to get a[i].
There is no easy way getting n-th element of the list.
In my opinion this indicates that your view and business logic are not separated enough: knowledge of what magic number 25 means is spread in both tiers.
One possible solution might be converting list of values to object which provides meaning to the elements. For example, lets say list of String represents address lines, in which case instead of map.("3") you would write address.street.
