[英]TypeScript. incompatible types in array. How to declare an object with method that can take array of any objects?
如何使用可以获取任何对象数组的方法声明对象?
在代码beloy中:(1)代码有一个编译错误'数组中的不兼容类型'。 (2)没有错误。 我想用(1)。
declare var enyo;
// (1). compile error: 'Incompatible types in array'
enyo.kind({
name: "HelloWidget",
components: [
{ name: "hello", content: "Hello From Enyo" },
{ kind: "Button", content: "Click Me!", ontap: "helloTap" }
]
});
// (2). no erros but have to write <any>
enyo.kind({
name: "HelloWidget",
components: [
<any>{ name: "hello", content: "Hello From Enyo" },
<any>{ kind: "Button", content: "Click Me!", ontap: "helloTap" }
]
});
最好的解决方法是提供关于enyo
一些类型信息,以便编译器可以将上下文类型应用于数组表达式:
interface EnyoComponent {
name?: string;
content?: string;
kind?: string;
ontap?: string;
}
declare var enyo: {
kind(settings: {
name: string;
components: EnyoComponent[];
});
};
enyo.kind({
name: "HelloWidget",
components: [
{ name: "hello", content: "Hello From Enyo" },
{ kind: "Button", content: "Click Me!", ontap: "helloTap" }
]
});
您可以使用any[]
在您的界面中完成此操作。
declare var enyo: {
kind(settings: {
name: string;
components: any[];
});
};
// The following will now compile without errors
enyo.kind({
name: "HelloWidget",
components: [
{ name: "hello", content: "Hello From Enyo" },
{ kind: "Button", content: "Click Me!", ontap: "helloTap" }
]
});
