Get Vuejs Store variable by String Value

Question

I'm trying to get a vuejs store variable like this :

const pathFile = `#pathFile_${this.devisDTO.code_produit}`; const pathApp = this.$store.state.parameters.urls.${pathFile};

So in the second line ${pathFile} is not interpreted in that way. Please could you help on how to write this ?

try this.$store.state.parameters.urls[pathFile]

In JavaScript ${string_name} is used inside template strings (1). If you want to access the value of a dictionary based on a string's content you should use the square brackets syntax. In your case

this.$store.state.url[path_file]

On a side note I suggest you to use store getters to access variables.

pathFile is a normal variable. Remove the brackets from it.

const pathFile = `#pathFile_${this.devisDTO.code_produit}`;
const pathApp = this.$store.state.parameters.urls.pathFile;

you need to modify your code remove brackets from parameters.urls.${pathFile} to .urls.pathFile;

here is code..

const pathFile = `#pathFile_${this.devisDTO.code_produit}`;
const pathApp = this.$store.state.parameters.urls.pathFile;

That's not valid javascript. I am guessing you meant to write the following:

const pathFile = `#pathFile_${this.devisDTO.code_produit}`;
const pathApp = this.$store.state.parameters.urls[pathFile];
