Angularjs - 将参数传递给指令 [英] Angularjs - Pass argument to directive
本文介绍了Angularjs - 将参数传递给指令的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想知道是否有一种方法可以将参数传递给指令?
我想要做的是从控制器追加一个指令,如下所示:
$ scope.title =title;
$ scope.title2 =title2;
angular.element(document.getElementById('wrapper'))。append('< directive_name>< / directive_name>')
可以同时传递参数,所以我的指令模板的内容可以链接
app.directive(directive_name,function(){
return {
restrict:'E',
transclude:true,
template:'< div class = >< h2> {{title}}< / h3>< / div>',
replace:true
};
})
$如果我想使用相同的指令,但使用$ scope.title2? $ b h2_lin>解决方案这是我如何解决我的问题:
指令
$ b
app.directive(directive_name,function(){
return {
restrict:'E',
transclude:true,
template:function(elem,attr){
return'< div>< h2> {{'+ attr.scope +'}}< / h2>< / div ;';
},
replace:true
};
})
控制器 b
$ scope.building = function(data){
var chart = angular.element(document.createElement('directive_name'));
chart.attr('scope',data);
$ compile(chart)($ scope);
angular.element(document.getElementById('wrapper'))。append(chart);
}
现在可以通过相同的指令使用不同的范围,并动态添加它们。 / p>
Im wondering if there is a way to pass an argument to a directive?
What I want to do is append a directive from the controller like this:
$scope.title = "title";
$scope.title2 = "title2";
angular.element(document.getElementById('wrapper')).append('<directive_name></directive_name>');
Is it possible to pass an argument at the same time so the content of my directive template could be linked to one scope or another?
here is the directive:
app.directive("directive_name", function(){
return {
restrict:'E',
transclude:true,
template:'<div class="title"><h2>{{title}}</h3></div>',
replace:true
};
})
What if I want to use the same directive but with $scope.title2?
解决方案 Here is how I solved my problem:
Directive
app.directive("directive_name", function(){
return {
restrict: 'E',
transclude: true,
template: function(elem, attr){
return '<div><h2>{{'+attr.scope+'}}</h2></div>';
},
replace: true
};
})
Controller
$scope.building = function(data){
var chart = angular.element(document.createElement('directive_name'));
chart.attr('scope', data);
$compile(chart)($scope);
angular.element(document.getElementById('wrapper')).append(chart);
}
I now can use different scopes through the same directive and append them dynamically.
