set/getWebViewString not working?

[TIMAI2]

@Dmlr2052

let charCodesString = charCodes.toString();

try with:

let charCodesString = JSON.stringify(charCodes);

and don't wrap getCharCodes(webString) in square brackets

		function getCharCodes(s) {     
			let charCodeArr = [];         
			for (let i = 0; i < s.length; i++) {
			let code = s.charCodeAt(i);
			charCodeArr.push(code);
			}
			return charCodeArr; 
		}
		let webString = window.AppInventor.getWebViewString();
		let charCodes = getCharCodes(webString); 
		let charCodesString = JSON.stringify(charCodes);
		window.AppInventor.setWebViewString(charCodesString);

works for me
