I am trying to print the football value which is inside array using JS. I am not sure how to print it in JS. Right now when I try it prints as undefined. I am providing part of my JS and JSON below, can you guys tell me how to fix it?
if (item.data.football == true) {
console.log("print football---->" + item.data[0].football);
}
"data": [{
"sportsProperty": "Insurance",
"football": true
},
{
"sportsProperty": "Insurance",
"football": true
}]
The data property of your object is an array, so you need to access its members by index. Try this:
if (item.data[0].football) { // note the [0] after 'data'
// do something...
console.log(item.data[0]);
}
The above will only access the first item in the array. If you want to work with all of them you need to use a loop, like this:
for (var i = 0; i < item.data.length; i++) {
if (item.data[i].football) {
// do something...
console.log(item.data[i]);
}
}
Are you declaring item? By writing item.data, you're implying that the data object lies within an item object. In order to work, your code should look something like the following:
var item = {
"data": [
{
"sportsProperty": "Insurance",
"football": true
},
{
"sportsProperty": "Insurance",
"football": true
}
]
};
Also, item.data.football returns undefined, because you need to specify a location within the array. Otherwise, you can ask:
if (!!item.data)
Which will return true if item.data is not an empty object.
Let me know if you need any further help.
