在其模板中使用Angular Directive属性 [英] Use Angular Directive attributes in its template

问题描述

如何在指令中使用属性的值?我的元素看起来像这样:

How can I use the value of an attribute in a directive? My element looks like this:

<div class="tooltip-icon" 
  data-my-tooltip="click" 
  data-tooltip-title="foo" 
  data-tooltip-content="test content"></div>

我想在指令模板中使用它，如下所示:

I would like to use that in the template of my directive, which looks like this:

mainApp.directive('myTooltip',
    function() {

        // allowed event listeners
        var allowedListeners = ["click"];

        return {
            restrict: 'A',
            template:   '<div class="tooltip-title">...</div>' +
                        '<div class="tooltip-content">' +
                        '...</div>',
            link: function(scope, elm, attrs) {
                if(allowedListeners.indexOf(attrs.myTooltip) != -1){
                    elm.bind(attrs.myTooltip, function(){
                        ...
                    });
                }

            }
        };
    }
);

应该有三点的代码，但是我无法弄清楚如何将attrs对象(attrs.tooltipTitle等)的内容放入该模板中.

Where the triple dots are there should be code, but I cannot figure out how to get the contents of the attrs object (attrs.tooltipTitle, etc) into that template.

推荐答案

您可以拉出属性并将其放入指令的范围内，如下所示:

You can pull the attributes out and place them into the scope of the directive like this:

angular.module('myApp', []).
directive('myTooltip', function ($log) {
    // allowed event listeners
    var allowedListeners = ["click"];
    return {
        restrict: 'A',
        template:   '<div class="tooltip-title">{{tooltipTitle}}</div>' +
                    '<div class="tooltip-content">' +
                    '{{tooltipContent}}</div>',
        scope: {
            tooltipTitle: '@tooltipTitle',
            tooltipContent: '@tooltipContent'
        },
        link: function (scope, elm, attrs) {
            if (allowedListeners.indexOf(attrs.myTooltip) != -1) {
                elm.bind(attrs.myTooltip, function () {
                    $log.info('clicked');
                });
            }

        }
    };
});
