角表带。酥料饼的程序中使用 [英] Angular Strap. Popover programmatic use
问题描述
我试图创造编程酥料饼，但面临着以下问题。我不能酥料饼的模板内访问父范围。预期的结果是：
I'm trying to create programmatically popover, but faced with following problem. I can't access parent scope inside popover template. Expected result is:
Hello my name is Roman
但我得到
Hello my name is undefined
下面是 plunker
如果我用 BS-酥料饼作为任何元素的属性，然后我得到预期的结果。
If I use bs-popover as attribute on any element, then I get expected result.

原型继承是范围默认棱角分明。
Prototype inheritance is default on scope in angular.
所以，如果你没有创建孤立的范围，那么你可以访问父范围从直接的范围，直到对象，除非你是不是覆盖他们。
So if you are not creating isolated scope then you can access parent scope objects from your scope directly until and unless you are not overriding them.
var myPopover = $popover(element, {
title: 'My Title',
contentTemplate: 'example.html',
html: true,
trigger: 'manual',
autoClose: true,
scope: scope
});
scope.showPopover = function() {
myPopover.show();
}
