Thanks for the advice.

Answer 1

There are too many methods, ng-click, ng-class, directive can be implemented.
This is a direct method, for reference only
html:

<p>
    <span ng-class="{'selected':selected==s}" ng-repeat="s in list" ng-bind="s" ng-click="changeStatus(s)"></span>
</p>

js

$scope.list = [1,2,3,4,5];
$scope.changeStatus = function(index){
    $scope.selected = index;
}

Answer 2

Add click event. Pass the $index and $event of the current loop. Then it's OK to handle it yourself through angular jq.

Answer 3

Give you a ready-made code:
HTML

<p class='options'>
    <span class='option' ng-class="{'selected':s._selected}" ng-repeat="s in orderStatus" ng-bind="s.l" ng-click="clickStatus(s)"></span>
</p>

JS

$scope.clickStatus = function(prop) {
    prop._selected = !prop._selected;
};

CSS

.option{display:inline-block;border:1px solid green;padding:.25em;margin:.5em .5em 0 0;}
.option.selected{background:green;color:white;}

I am planning to write a directive to do this
