I'd like to have a form with multiple Polymer list boxes in it.
<paper-listbox selected="0">
<paper-item>Item 1</paper-item>
<paper-item>Item 2</paper-item>
<paper-item>Item 3</paper-item>
</paper-listbox>
<paper-listbox selected="0">
<paper-item>Item A</paper-item>
<paper-item>Item B</paper-item>
<paper-item>Item C</paper-item>
</paper-listbox>
When I do this, I am only able to select one item in both lists. How do I enable selection one from each list?
You most likely would have use same variable in the selected={{myVariable}} attribute in both the listboxes. You can use different variables in different listbox selected={{myVariableOne}} for the first listbox and selected={{myVariableTwo}} for the second listbox.

I have odata coming from backend. I have two select controls on my SAPUI5 page. The first select displays a list of items received from the backend. The second select changes depending on what is selected from the first select control.
Right now I am constructing in the controller a new path for "planets" select. Is it possible to change the "planets" items path depending on the "stars" selected item just in the XML? Without using Javascript?
I would like to do something like this:
<Select id="stars"
items="{
path: '/Stars'
}">
<core:Item key="{StarID}" text="{StarName}" />
</Select>
<Select id="planets"
items="{
path: '("/Stars('" + StarID + "')/toPlanets"'
}">
<core:Item text="{PlanetName}" />
</Select>
Unfortunately, I do not believe that there is any existing functionality to do something like this naively in UI5. The only thing that is similar is binding replacement during XML preprocessing, but you cannot use that for your situation.
I have met this situation a lot of times in the past and have created a helper control for dealing with this (might not be the perfect solution, but it works). It only makes sense to use a similar approach if you have this kind of construct in multiple places (so you avoid having the same boilerplate code in your JS controllers).
You can find here an example implementation of such a control and here an example usage. Basically this allows you to have a reusable mechanism for doing such an "indirect binding" without resorting to event listeners.
I'm using select2.full.js
I'm not using any require.js to help me pull in modules, I'm basically using my know how from everything I learned in v3.5
I've been trying countless of hours, wrapping my head around this, but I have no idea how to make ajax cascading dropdowns.
Example: You load up the page, there is the first select2 dropdown that pulls data using ajax automatically (you don't enter anything.. data is there on the page load from the server), a default value is selected. Since that default value is selected, the second select2 drop down will use that value to make an ajax call to populate its own list. Now, when I select another value in the first select2 dropdown, the second select2 dropdown will reflect those changes with the new dataset.
What I've able to come up with was a 3 dropdowns that you can populate on a page load, but when you do any ajax request, the dropdown data doesn't change.
It's been two years since I used select2, and the library keeps changing, the documentation keeps changing, I'm at my wits end with this library. But I feel drawn to it by the bootstrap support, and the look and feel. The functionality, the way to implement things, the documentation is just so unbelievably awful.
I don't have any useful code at all, I've been pulling, plugging, modifying, etc.. and now I'm moving to my hair and teeth.
ANY useful example to do this would be awesome.
Just found my answer..
I was using the templating:
<select id="test">
<option value="1">1</option>
<option value="2">2</option>
</select>
to:
data = [{id: "1", text: "1"}, {id: "2", text: "2"}];
<input id="test" type="hidden" />
and just kept my jquery on select2 the same. So it was really just a change in the templating from to that solved it.
However, the only downside to this is that when you are refreshing new data from these drop downs, the highlighted (selected value) is always the first item in the drop down list, even though that's not the selected value shown in the dropdown.
Here is a small code snippet to make Select2 (v4.x) cascading dropdown - https://gist.github.com/ajaxray/187e7c9a00666a7ffff52a8a69b8bf31
Using this module, options of a select2 list box will be loaded/refreshed by ajax based on selection of another select2 list box.
Example use -
new Select2Cascade($('#province'), $('#district'), 'path/to/geocode', {type:"district", parent_id: ''});
Selected value of parent select2 listbox will be set to the parent_id of the data object before ajax call.
Given two similar domains Foo and Bar, is it possible to create a g:select tag that can choose from both of them? E.g.,
<g:select from="${[Foo.list(), Bar.list()]}"/>
That, unfortunately, does not work. It creates a single option that is the text of all items from both domains :|
So, does anybody know if this can be done?
Edit
Nope, it doesn't make any difference to pass this list in from the controller.
<g:select from="${Foo.list() + Bar.list()}"/>
would also do just fine
Whoops, just needed to flatten the list!
<g:select from="${[Foo.list(), Bar.list()].flatten()}"/>
Otherwise, it was a list of lists.
In the following html code, One of the div is hidden and the other one is not.My question is
1.how to select any element with multiple class names with hidden attribute
2.how to get the inner html when the html is hidden or shown
I tried,
$('.middle-cont,.float-lft,.content-height').html()
$('.middle-cont,.float-lft,.content-height:hidden').html() //will this work
html
<div class="middle-cont float-lft content-height">
some html
</div>
<div class="middle-cont float-lft content-height" > //This div is hidden
some html123
</div>
no comma's, commas will select all elements with either of the classes, while removing the comma's will select the elements that has all the classes :
$('.middle-cont.float-lft.content-height').html()
wether or not it's hidden makes no difference for this.
FIDDLE
you don't need , to select element with multiple class....use html() to get the content.. (it doesn't matter if it is hidden or not)
$('.middle-cont.float-lft.content-height').html()
Comma using as OR operator, you dont need it here so:
$('.middle-cont.float-lft.content-height').html()
It's not matter that your element is hidden or not.
Try like this
var innerHtml = $(".middle-cont").filter(".float-lft").filter(".content-height").html();
alert(innerHtml);

I am trying it with javascript, but because of struts html taglibrary, i am getting problems here, could u please give me solutions to resolve this problem anyone.
and can anybody tell how to get dropdown selection value into javascript(if we are using tag library in struts)
How are you using javascript to create your view? You should be able to use
<logic:iterate>
to traverse your product collection, then
<bean:write .../>
to display information from each product.
<html:select>
will create a dropdown in your form. Use
<html:option>, <html:options>, or <html:optionsCollection>
to populate each item in the dropdown.
