Disregard the ng-blur event for specific elements

Question

Disregard the ng-blur event for specific elements

In my search feature, I have a suggestion box that appears below the search field when I start typing. I want the suggestion box to disappear when I click outside the search field, and also be able to click on a suggestion to perform a search.

<input ng-blur="suggestionBox.hide()" ng-model='someModel' />

<div class='suggestion-box'>
<ul>
<li ng-repeat="suggestion in suggestions" ng-click="someFunction()">suggestion.name</li>
</ul>
</div>

The issue I am facing is that the ng-click is not triggered when the ng-blur hides the suggestion box. I have tried using

ng-click="$event.preventDefault(); someFunction()"

but it did not work. I also attempted to set a timeout on the hide() method, which worked but required a long delay of 200ms, making it an inefficient solution.

Answer №1

My approach involves utilizing ng-mousedown and ng-mouseup functions to handle click events without relying on onBlur. This technique was particularly useful when implementing a cancel edit button.

When mousedown occurs, I set a flag "inWhateverMode = true". This step is crucial as it happens before the blur event.
In the blur handler, I check for the presence of inWhateverMode.
Upon mouseup, I clean up any flags and carry out the desired action.

This method proves beneficial in scenarios where users need to click a button, move the cursor away, and release without unintended consequences, such as accidentally triggering a delete action.

Hey there, I believe I have found the solution you were seeking:

http://example.com/edit/3hjgij45hjgjhf

Is the issue that the function executes, but the drop-down menu disappears afterwards?

$scope.display = function(element) { $scope.hideElement = true; alert(element); };

Updated HTML:

<input ng-model='search' />
<div ng-hide='hideElement' style='border:1px solid black'>
