How to convert a single string to object
Question
I have multiple objects and trying to do a condition based on the object name. I am trying to check the name of the object based on the variable, which is a string. Is there any way to convert a single value string to object
const showHtml= {
one: {
code: "<DIV>",
pos: "1"
},
two: {
code: "<Body>",
pos: "2"
}
}
const showcss= {
one: {
code: "text-align",
pos: "1"
},
two: {
code: "float",
pos: "2"
}
}
I have a string variable (showHTML and showcss). I want to return the code based on the variable, so i am doing
let uVariable = localstorage.getItem("ftype")
console.log(uVariable.one.code)
I should get
<DIV>
but as i am passing the string, I can't get the object name, is there any way to convert the uVariable into object?
Thank you

You want JSON.parse here. Localstorage only stores strings. In your case, the code would look something like this:
let uVariable = JSON.parse(localstorage.getItem("ftype"))
console.log(uVariable.one.code)
String => object, use JSON.parse Object => string, use JSON.stringify

please read this code, might help you so initially we have variable showHtml which contains json data.
you should try this
JSON.parse(localStorage.getItem('showHtml')).one.code
and you can try jsfiddle: https://jsfiddle.net/dupinderdhiman/f5wz7Lv1/2/
for more explanation read below:
var showHtml= {
one: {
code: "<DIV>",
pos: "1"
},
two: {
code: "<Body>",
pos: "2"
}
}
var showcss= {
one: {
code: "text-align",
pos: "1"
},
two: {
code: "float",
pos: "2"
}
}
localStorage.setItem('showcss', JSON.stringify(showcss));
localStorage.setItem('showHtml', JSON.stringify(showHtml));
alert('showHtml '+JSON.parse(localStorage.getItem('showHtml')).one.code);
alert('showCss '+JSON.parse(localStorage.getItem('showcss')).one.code)
