I want to have a button appear when the user focuses on an input with the ng-model=query. I know there is an ng-focus directive, but how can I implement it?
<input type="search" ng-model="query">
<!--this is the button I need to show once the user focus the input-->
<div ng-show="query.length"
ng-click="query = ''">
Cancel
</div>
This is the button that should display when the user focuses on the input. Instead of using ng-show, what alternative could I consider?
If you're looking to implement this functionality using pure angular, the code would appear as follows:
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app>
<input
type="search"
ng-model="query"
ng-focus="isSearchFocused=true"
ng-blur="isSearchFocused=false"/>
<div
style="opacity:{{isSearchFocused && query.length?1:0}}"
ng-click="query = ''">
Cancel
</div>
</div>If you want to break away from pure AngularJS and utilize CSS instead for a particular action, there are several approaches you can take. One effective method is using the plus (+) selector as shown below:
HTML
<input type="search" ng-model="query">
<!--this is the button I need to show once the user focus the input-->
<div class="hidden_btn" ng-show="query.length" ng-click="query = ''">
Cancel
</div>
CSS
.hidden_btn { /* Hide this button initially */
display: none;
}
input[ng-model="query"]:focus + .hidden_btn {
display: block;
}
There are alternative ways to achieve this functionality, which can be found in the following link: AngularJS: show hide elements based on mouse events. These techniques can not only be applied to your specific ng-model selector but also to similar methodologies within AngularJS.
If you have any queries, feel free to ask!
To select adjacent siblings, use the + selector.
div.dat_div {
display: none;
}
input[ng-model="query"]:focus + div.dat_div {
display:block;
}<input type="search" ng-model="query">
<!--this is the button I need to show once the user focus the input-->
<div class="dat_div" ng-show="query.length" ng-click="query = ''">
Cancel
</div>In jQuery:
$('input[ng-model="query"]').on('focus',function(){$('div.dat_div').show();});My goal is to extract specific information from a webpage by utilizing this code snippet to target an element and retrieve certain values within it: const puppeteer = require('puppeteer'); function run (numberOfPages) { return new Promise(a ...
