I am facing the issue with :

I am using a lookup with lightning: input. When the user clicks enter search text in this input field. New component opens up showing related search records.

Now to close search window, I have a cross button in front of the field.

The user wants that on clicking anywhere outside search result component/box. This component should get closed. Now I am unable to find any workaround of attribute keyUp which we use in ui:input. Any idea how to achieve that.

enter image description here

    have you tried wrapping your input in a div tag with the keyup attribute? I recall lightning:input not fully supporting this, hence the wrapping in a div (or any other html tag that supports onkeyup

  • It sounds like you actually want onblur, not onkeyup? That will tell you when they've clicked outside of the lightning:input

  • Thanks for suggestions! but the issue is as you can see this is a Multi check box. So when I click on a single checkbox, onblur gets called and dropdown goes off. I want, it should not go off when clicked within this component. it should go when clicked outside only. Please suggest. Commented Mar 19, 2018 at 17:13

You can add the keyup to and input field, you just have to specify UpdateOn so that the change event triggers on keyup

<ui:inputText aura:id="searchInput" 
    updateOn="keyup" />


Edit: I'm pretty sure this will work on a lightning:input as well, but I haven't tested that.

  • I don't see updateOn documented in e.g. lightning:input (Beta).
