I am trying to walk through a JS object, with the for_in loop. That seems to be returning the found value (contentCard1) as plain text. I can't get it to print val.text
var contentCards = {
contentCard1: {text: "text in here", date: "date in here"}
}
for(var val in contentCards) {
console.log(val.text);
}
Logging val.text gives me undefined, and logging just val gives me contentCard1.
Thanks for helping.
With for ... in, you are iterating over the keys of contentCards. For the access you need the object and the key with bracket notation.
contentCards[val].text
// ^^^^^
var contentCards = { contentCard1: { text: "text in here", date: "date in here" } };
for (var val in contentCards) {
console.log(contentCards[val].text);
}.as-console-wrapper { max-height: 100% !important; top: 0; }Used this:
var contentCards = {
contentCard1: { text: "text in here", date: "date in here" }
}
alert(contentCards.contentCard1.text);
val in contentCards and then never use val, what's the point of the loop? Every iteration would alert the same, specific value.
