如何检查直接传递给节点C ++插件(不是通过JS包装器)的参数是NaN还是+/- Infinity?
我尝试frexp(arg[0]->NumberValue(), &exponent)
,目的是检查指数是否为2047(JS如何表示NaN和Infinity),但显然Local<Value>->NumberValue()
模糊了double并更改了exp值。

对于C ++ 11,回复是
Template.home.helpers({
todos: function() {
return Todos.find();
},
todoCount: function() {
return Todos.find({userid: Meteor.userId()}).count();
},
settings: function() {
return {
position: "top",
limit: 5,
rules: [
{
token: '@',
collection: 'Todos',
field: "title",
subscription: 'todosAuto',
template: Template.titlePill
},
{
token: '#',
collection: 'Todos',
field: "categories",
options: '',
subscription: 'todosAuto',
matchAll: true,
template: Template.dataPiece
}
]
};
}
});
Template.home.events({ // listen for selection and subscribe
"autocompleteselect input": function(event, template, doc) {
Meteor.subscribe("todosAuto", doc.title);
}
});
