<input focus-if />

(function() {
    'use strict';
    angular
        .module('focus-if', [])
        .directive('focusIf', focusIf);

    function focusIf($timeout) {
        function link($scope, $element, $attrs) {
            var dom = $element[0];
            if ($attrs.focusIf) {
                $scope.$watch($attrs.focusIf, focus);
            } else {
                focus(true);
            }
            function focus(condition) {
                if (condition) {
                    $timeout(function() {
                        dom.focus();
                    }, $scope.$eval($attrs.focusDelay) || 0);
                }
            }
        }
        return {
            restrict: 'A',
            link: link
        };
    }
})();

以编程方式调用元素上的任何操作:click()， focus()， select()…

用法:

<a href="google.com" auto-action="{'click': $scope.autoclick, 'focus': $scope.autofocus}">Link</a>

指令:

/**
 * Programatically Triggers given function on the element
 * Syntax: the same as for ng-class="object"
 * Example: <a href="google.com" auto-action="{'click': autoclick_boolean, 'focus': autofocus_boolean}">Link</a>
 */
app.directive('focusMe', function ($timeout) {
    return {
        restrict: 'A',
        scope: {
            autoAction: '<',
        },
        link: function (scope, element, attr) {
            const _el = element[0];
            for (const func in scope.autoAction) {
                if (!scope.autoAction.hasOwnProperty(func)) {
                    continue;
                }
                scope.$watch(`autoAction['${func}']`, (newVal, oldVal) => {
                    if (newVal !== oldVal) {
                        $timeout(() => {
                            _el[func]();
                        });
                    }
                });
            }

        }
    }
});

要解决这个问题，最好在controller或ng-init中设置初始化变量:

 <input ng-init="autofocus=true" auto-action="{'focus': autofocus}">

我发现其他一些答案过于复杂，而你真正需要的只是这个

app.directive('autoFocus', function($timeout) {
    return {
        restrict: 'AC',
        link: function(_scope, _element) {
            $timeout(function(){
                _element[0].focus();
            }, 0);
        }
    };
});

使用

<input name="theInput" auto-focus>

我们使用超时来让dom中的东西呈现，即使它是零，它至少会等待它-这种方式也适用于模态和其他东西

            if ($attrs.focusIf) {
                $scope.$watch($attrs.focusIf, focus);
            } else {
                focus(true);
            }
            function focus(condition) {
                if (condition) {
                    $timeout(function() {
                        dom.focus();
                    }, $scope.$eval($attrs.focusDelay) || 0);
                }
            }
        }
        return {
            restrict: 'A',
            link: link
        };
    }
})();

很容易. .试试这个

html

<select id="ddl00">  
 <option>"test 01"</option>  
</select>

javascript

document.getElementById("ddl00").focus();

不确定依赖超时是否是一个好主意，但这适用于ng-repeat，因为这段代码在angularjs更新DOM后运行，所以你要确保所有对象都在那里:

myApp.directive('onLastRepeat', [function () {
        return function (scope, element, attrs) {
            if (scope.$last) setTimeout(function () {
                scope.$emit('onRepeatLast', element, attrs);
            }, 1);
        };
    }]);
    //controller for grid
    myApp.controller('SimpleController', ['$scope', '$timeout', '$http', function ($scope, $timeout, $http)
    {
        var newItemRemoved = false;
        var requiredAlert = false;
        //this event fires up when angular updates the dom for the last item
        //it's observed, so here, we stop the progress bar
        $scope.$on('onRepeatLast', function (scope, element, attrs) {
            //$scope.complete();
            console.log('done done!');
            $("#txtFirstName").focus();
        });
    }]);
