The value of the precipitated polymer core
I am using a core-dropdown box in my form along with other core and paper elements. I can get the values ββfor all inputs, but I cannot get the value of the dropdown field on the submit form. According to the documentation, there is a property selectedItem
that can be used to get the selected value, but there are no instructions on how to use it.
On a separate note, although I can post resin paper input fields using this solution , but if there is another elegant solution for handling a resin form, preferably any type of field, like text, radio, checkbox, select, file, etc. then please share.

The polymer API is changing rapidly, but currently the way to work with dropdowns and selections is <core-selector>
element .
So, inside yours core-dropdown
, you will have something like this:
<core-selector selected="{{selectedIndex}}">
<div>Item 1</div>
<div>Item 2</div>
<div>Item 3</div>
</core-selector>
You can bind to an attribute selected
that represents either the index of the selected element or a specific attribute value, if used valueattr
.
Polymer('selector-example', {
ready: function () {
this.selectedIndex = 2; // 'Item 3' will be selected
}
});
Unfortunately I cannot expand my solution as the link is broken.
Hope it helps.
