ng-repeat Finish Event
Question:
How to call a jQuery function that targets a table populated with ng-repeat elements, after the ng-repeat population completes?
Answer:
Directives
Since there's no dedicated event tied to the end of an ng-repeat loop, directives offer a suitable solution.
Table-Wide Targeting
For styling or adding events to the entire table, use a directive that encompasses all ng-repeat elements.
Individual Element Targeting
To manipulate individual elements, place a directive within the ng-repeat. It will execute on each element after its creation.
$index, $first, $middle, and $last Properties
Leverage these properties to trigger events based on element positions:
- $index: Current element's index
- $first: True if the element is the first in the loop
- $middle: True if the element is between the first and last
- $last: True if the element is the last in the loop
Directive Example
The following directives demonstrate how to use the properties and target the table and individual elements:
angular.module('myApp', [])
.directive('myRepeatDirective', function() {
return function(scope, element, attrs) {
angular.element(element).css('color','blue');
if (scope.$last){
window.alert("I'm the last!");
}
};
})
.directive('myMainDirective', function() {
return function(scope, element, attrs) {
angular.element(element).css('border','5px solid red');
};
});
This approach allows for both comprehensive table manipulation and granular element-specific actions.
