Javascript - Javascript函数在AngularJS加载HTML元素之前运行,因此函数不会获取元素

我想在DOM元素上绑定AddEventListener纯javascript方法。 但是我使用包含html文件的AngularJS,这包括在AddEventListner函数绑定到DOM之后运行。所以纯JavaScript没有找到DOM。 我是纯JS字的新手。我使用了jQuery,但在这个项目中我只想使用AngularJS和纯JS。 :)

AngularJS

包含此代码(ng-include)
<div class="col-xs-3 col-md-1 col-xs-offset-2 col-md-offset-0 padding-left-right-0">
                <span class="game game-home" ng-show='gameEvent.game_home > 0' ng-click="addToSlip(gameEvent.id, gameEvent.name, gameEvent.game_home, 'H', gameEvent.number)" style="cursor: pointer;">
                    <span class="slip-game-event-add-button">
                        {{ gameEvent.game_home | number:2 }}
                    </span>
                    <span class="badge">{{ gameEvent.taken_home}}</span>
                </span>
            </div>
            <div class="col-xs-3 col-md-1 padding-left-right-0">
                <span class="game game-draw" ng-show='gameEvent.game_draw > 0'ng-click="addToSlip(gameEvent.id, gameEvent.name, gameEvent.game_draw, 'D', gameEvent.number)" style="cursor: pointer;">
                    <span class="slip-game-event-add-button">
                        {{ gameEvent.game_draw | number:2 }}
                    </span>
                     <span class="badge">{{ gameEvent.taken_draw}}</span>
                </span>
            </div>
            <div class="col-xs-3 col-md-1 padding-left-right-0">
                <span class="game game-away" ng-show='gameEvent.game_away > 0' ng-click="addToSlip(gameEvent.id, gameEvent.name, gameEvent.game_away, 'V', gameEvent.number)" style="cursor: pointer;">
                    <span class="slip-game-event-add-button">
                        {{ gameEvent.game_away | number:2 }}
                    </span>
                    <span class="badge">{{ gameEvent.taken_away}}</span>
                </span>
            </div>

这是我的纯javascript文件:

'For.the.view';

(function() {
    var gameDom = document.getElementsByClassName("game");

    for (var i=0;i<gameDom.length;i++) {
        gameDom[i].addEventListener('click', clickEventForThis, false);
    };
})();

function clickEventForThis(){
    console.log("hello");
};

不幸的是,在AngularJS加载HTML文件之前,这个javascript代码会运行。所以它找不到任何gameDoms ......

是的,最简单的方法是使用“onclick”attributate,但我认为这不是一个好的解决方案。

您可以使用angular.ready事件:

angular.element(document).ready(function () {
    var gameDom = document.getElementsByClassName("game");

    for (var i=0;i<gameDom.length;i++) {
        gameDom[i].addEventListener('click', clickEventForThis, false);
    };
});
