为什么不起作用bundle exec spring?
我已经在调用bundle exec并返回错误.我可以bundle exec随时打电话.(这是可能的重复问题的解决方案).
我不会通过bundle update spring或卸载版本spring来更新我的Gemfile 以使其工作.我不应该被迫改变我的宝石安装.
bundle binstubs spring 也没有工作.

APP = (function() {
var x,y,z;
function foo() {}
function bar() {}
return {x:x, y:y, z:z, foo:foo: bar:bar};
})();

这样做的好处是它创建了非全局变量,其中的函数可以访问定义的所有内容APP.所以APP.foo可以访问x, y, z,而无需打字吧APP.bar(),APP.x等一切都还可以与全球访问APP.bar(),APP.x等等.你也可以嵌套它们:
APP = (function() {
var x,y,z;
function foo() {}
function bar() {}
var WIDGETS = (function() {
var a,b,c;
function hello() {}
function world() {}

有没有更好的选择GMSMapViewDelegate:
- (void)mapView:(GMSMapView *)mapView
didTapInfoWindowOfMarker:(id<GMSMarker>)marker;?
(对用户来说,点击信息窗口并不明显......)

一直试图让以下代码在firefox附加组件中工作:
var oMyForm = new FormData();
oMyForm.append("username", "Groucho");
oMyForm.append("accountnum", 123456); // number 123456 is immediately converted to string "123456"
// HTML file input user's choice...
oMyForm.append("userfile", fileInputElement.files[0]);
// JavaScript file-like object...
var oFileBody = '<a id="a"><b id="b">hey!</b></a>'; // the body of the new file...
var oBlob = new Blob([oFileBody], { type: "text/xml"});
oMyForm.append("webmasterfile", oBlob);
