updateDom() blocks MagicMirror

1BlauNitrox

@sdetweil Is there a Json parser I can use?

sdetweil

@1blaunitrox said in updateDom() blocks MagicMirror:

Why can getDom() not transfrom the array in a readable string?

getDom() CAN do anythign YOU implement… it does NOTHING by itself…

sdetweil

@sdetweil JSON.parse, JSON. stringify

u have an object so, stringify turns it into text
parse takes text and makes an object

1BlauNitrox

@sdetweil What about JSON.stringify(this.response);

sdetweil

@1blaunitrox that would work

but it will be the JSON text representation of the object

all fields and values

@sdetweil
First: Is there an other option?

Second: I added the getData() function in getDom()

        const wrapper = document.createElement("div");
        this.getData();
        if(this.response.lenght <= 0) {
            wrapper.innerHTML = "No Entries";
        } else {
            wrapper.innerHTML = JSON.stringify(this.response);
        }
        return wrapper;

Now the mirror show UNDEFINED again

sdetweil

@1blaunitrox length

spelling matters…

use the debugger

sdetweil

@1blaunitrox this.getData() is not synchronous, so it will return long before the data is ready

don’t call from getDom()

@sdetweil Do you remember my problem yesteray that my magic mirror doesn`t start? I started the program today in the morning. Without doing anythink since yesterday evening, the same error occurs.

The only think I change was that I renamed lenght to length. Than I deleted the module module and copyed the new one.
