I attempted to utilize an AngularJS variable as an argument value inside onclick() in order to invoke a JavaScript function. Can someone provide me with instructions on how to achieve this?
Here is my code:
<div onclick="deleteArrival({{filterList.id}})" class="table-icon deleteIcon">{{filterList.id}}</div>
It is recommended to utilize ng-click instead of onclick in Angular, as Angular offers this functionality.
<div ng-click="deleteArrival(filterList.id)"
class="table-icon deleteIcon">{{filterList.id}}</div>
The appropriate approach is to relocate your function to the AngularJS Controller and bind it to the scope.
$scope.deleteArrival = function(filterListId) { ... };
If for some reason you must use onclick to invoke an external function, you can modify the function within your scope as shown above, while still utilizing the ng-click attribute.
$scope.deleteArrival = function(filterListId) { window.deleteArrival(filterListId); };
Nevertheless, there is no compelling reason not to place it within your scope.
In case you prefer utilizing onclick, the following code worked successfully for me. Hopefully, it will work for you as well.
<div id="{{filterList.id}}" onclick="deleteArrival(this.id)" class="table-icon deleteIcon">{{filterList.id}}</div>
Instead of questioning your decision to not utilize ng-click, I respect your choice. But if you find it necessary, here's a different approach using 'this' and data attributes.
<div data-filterListId="{{filterList.id}}" onclick="deleteArrival(this)" class="table-icon deleteIcon">{{filterList.id}}</div>
function deleteArrival(arrivalElem) {
alert('myId=' + arrivalElem.getAttribute("data-filterListId"));
}
To effectively address your issue, consider implementing the ng-click feature along with the required deleteArrival function within your scope.
Code Snippet
<div ng-click="deleteArrival(filterList.id)" class="table-icon deleteIcon">
{{filterList.id}}
</div>
It's quite simple to achieve the desired functionality by utilizing the ng-click directive in combination with a function placed within the controller scope. The key is to assign the reference of your JavaScript function to a variable within the controller scope, eliminating the need to redefine the function. By passing the function reference, you can easily accomplish the task.
Example Markup:
<div ng-click="deleteItem(item.id)" class="delete-icon"></div>
{{item.id}}
Corresponding Controller Section:
// Assign the JavaScript method reference within the controller
$scope.deleteItem = deleteItem;
In AngularJS, it is important to note that creating bindings for event handler attributes such as onclick, onload, onsubmit, etc. is not permissible. This restriction is put in place to prevent exposing your application to security threats like XSS. As a result, AngularJS does not support binding to event handler attributes that begin with "on" and the formaction attribute.
For your specific scenario,
When using ng-repeat, utilize ng-click to pass values to your function and define that function in the controller.
Refer to this link for documentation on ng-click.
I hope this explanation proves beneficial!

In a particular scenario, I encountered issues using ng-click because of window binding. Although I didn't receive a straightforward solution, the following approach proved effective for me. I understand that it may not be the ideal fix, but it served its purpose in my situation.
Consider accessing the desired variable using the following code snippet:
angular.element(this).scope().ctrlName.variable
You may also explore creating your own class structure to handle the click event, like so:
onclick="test(angular.element(this).scope().ctrlName.ObjName.variable)"
$scope.displayMessage = function(message){
console.log(message);
}<p onclick='displayMessage("Hello World")' class="btn-primary btn'>Click Me!</p>
<b>I'm loving this functionality!</b>In a scenario where my application heavily relies on a large JavaScript file with functions not written in Angular, I faced the challenge of integrating them. To resolve this, I implemented a controller function to interact with one of these external JS functions:
$scope.controllerFunction = function() {
javaScriptFunction('foo');
}
javascriptFunction(parameter){
let variable = parameter
}
Using ng-click in my view, I called the controller function like this:
ng-click="controllerFunction()"
Upon investigating, I found that the example using "onclick="deleteArrival(this.id)" was returning undefined in my case. The approach described above proved to be the most effective solution for me.
