Imagine you have a JSON structure that looks like this:
[
{
"name":"Foo"
"nickname":"Lorem Ipsum"
},
{
"name":"Bar"
"nickname":"Dolor Sit"
}
]
Now, the goal is to extract the nickname of an item based on its value. Is there a way to achieve this in JavaScript?
To ensure the input is in proper JSON format, the correction suggested in my comment should be implemented. This function will then effectively fulfill its intended purpose.
function findByName(name) {
const data = [{
"name": "Foo",
"nickname": "Lorem Ipsum"
},
{
"name": "Bar",
"nickname": "Dolor Sit"
}
]
return data.find(item => item.name === name).nickname;
}
const result = findByName("Foo"); // ==> "Lorem Ipsum"
console.log(result);The variable selected is a global one and accessed using this.selected, which reliably returns the correct value. However, when called from a dynamically created function, it returns unknown. onClick: function(val){ for (i = 0; i < positi ...
