我有一段这样的代码:
Module.Article.directive('article', function ($compile) {
return {
restrict: 'C',
link: function (scope, element, attrs) {
var el = angular.element('<div></div>');
scope.showNum = function(i){
console.log(i);
};
for (var i = 1; i <= 5; i++) {
el.append('<span ng-mouseover="showNum(i)">' + i + '</span>');
}
$compile(el)(scope);
element.append(el);
}
我希望得到这个结果:
<div>
<span ng-mouseover="showNum(1)">1</span>
<span ng-mouseover="showNum(2)">2</span>
<span ng-mouseover="showNum(3)">3</span>
<span ng-mouseover="showNum(4)">4</span>
<span ng-mouseover="showNum(5)">5</span>
</div>
但我得到了这样的结果:
<div>
<span ng-mouseover="showNum(i)">1</span>
<span ng-mouseover="showNum(i)">2</span>
<span ng-mouseover="showNum(i)">3</span>
<span ng-mouseover="showNum(i)">4</span>
<span ng-mouseover="showNum(i)">5</span>
</div>
有人知道如何将我传递给showNum()处理程序吗?

将其更改为此,因此实际的i
变量将被打印而不是字母i:
Module.Article.directive('article', function ($compile) {
return {
restrict: 'C',
link: function (scope, element, attrs) {
var el = angular.element('<div></div>');
scope.showNum = function(i){
console.log(i);
};
for (var i = 1; i <= 5; i++) {
el.append('<span ng-mouseover="showNum(' + i + ')">' + i + '</span>');
}
$compile(el)(scope);
element.append(el);
}
编辑:我同意另一个答案提供了更大的灵活性,这个答案指出了提出问题的人试图实现它的方式中的一个小错误。

您可以使用ng-repeat
呈现template
并传递值,只需要在指令链接函数中创建items
数组,ng-repeat
将处理渲染部分HTML。
<强>指令强>
Module.Article.directive('article', function($compile) {
return {
restrict: 'C',
template: '<div>' +
'<span ng-repeat="i in items" ng-mouseover="showNum(i)">{{i}}</span>'+
'</div>',
link: function(scope, element, attrs) {
var el = angular.element('<div></div>');
scope.showNum = function(i) {
console.log(i);
};
scope.items = [];
for (var i = 1; i <= 5; i++) {
scope.items.push(i)
}
}
}
});
