请帮助我,我们如何让 AngularJS 编译指令生成的代码?
您甚至可以在这里找到相同的代码,http://jsbin.com/obuqip/4/edit
HTML
<div ng-controller="myController">
{{names[0]}} {{names[1]}}
<br/> <hello-world my-username="names[0]"></hello-world>
<br/> <hello-world my-username="names[1]"></hello-world>
<br/><button ng-click="clicked()">Click Me</button>
</div>
JavaScript
var components= angular.module('components', []);
components.controller("myController",
function ($scope) {
var counter = 1;
$scope.names = ["Number0","lorem","Epsum"];
$scope.clicked = function() {
$scope.names[0] = "Number" + counter++;
};
}
);
// **Here is the directive code**
components.directive('helloWorld', function() {
var directiveObj = {
link:function(scope, element, attrs) {
var strTemplate, strUserT = attrs.myUsername || "";
console.log(strUserT);
if(strUserT) {
strTemplate = "<DIV> Hello" + "{{" + strUserT +"}} </DIV>" ;
} else {
strTemplate = "<DIV>Sorry, No user to greet!</DIV>" ;
}
element.replaceWith(strTemplate);
},
restrict: 'E'
};
return directiveObj;
});
这是一个不使用编译函数和链接函数的版本:
myApp.directive('helloWorld', function () {
return {
restrict: 'E',
replace: true,
scope: {
myUsername: '@'
},
template: '<span><div ng-show="myUsername">Hello {{myUsername}}</div>'
+ '<div ng-hide="myUsername">Sorry, No user to greet!</div></span>',
};
});
请注意,模板包装在 中,因为模板需要有一个根元素。 (如果没有 ,它将有两个 根元素。)
HTML 需要稍微修改一下,以插入:
<hello-world my-username="{{names[0]}}"></hello-world>
Fiddle.
