How can I get value or component type by string?
I want to judge a variable in code, such as ‘cc.SpriteFrame’, ‘cc.Animation’, ‘cc.AnimationClip’ or ‘cc.Prefab’.

Thanks.

Does anyone have any advice?

It seems Cocos-Creator editor distinguishing type of files, since they are not accepting non coresponding type files.
I want to do same.

Take a look at “Property declaration” part:
http://www.cocos2d-x.org/docs/creator/en/scripting/class.html
Your own components can also be used as property type:

cc.Class({
	properties : {
		myComp : {
			type : require('MyComponentScript'),
			default : null,
		}
	}

Hi persy,

Thank you for the answer but what I want to do is judge a variable and / or component it my code.
#My question might not clear. sorry.
Your suggested document seems not explaining about how to judge.

Thanks.

You can use JavaScript operators typeof and instanceof to check type of a value.
If you want to have a variable that can only have values of a certain type - I believe there is no support for this in JavaScript, you may want to check TypeScript

Thanks.
I realized what I wanted to do with the code below.

return_type = function (x) {
    if (typeof (x) == 'object') {
        if (x instanceof cc.SpriteFrame) {
            return 'SpriteFrame';
        }
        if (x instanceof cc.AnimationClip) {
            return 'AnimationClip';
        }
        if (x instanceof cc.Prefab) {
            return 'Prefab';
        }
        if (x instanceof cc.Component) {
            return 'Component';
        }
        // .....
        return 'Unknown object';
    }

    return typeof(x);
};
