I have list of objects named data.
And 1 input tag.
I want to check that if input value exists in data's person1 key. If exist I write input value and person2 keys value. Else write I don't understand.
How this code gives true answer. this is wrong.
Try How old are you this. If you input this it must give I don't understand 2 times and 30
function SendMessage() {
var input = document.getElementById('person'),
sender = document.createElement('p'),
receiver = sender.cloneNode(true),
data = [{
"person1": "Hey",
"person2": "Hey, How are you?"
}, {
"person1": "Hello",
"person2": "Hello friend"
}, {
"person1": "How old are you",
"person2": "30"
},
];
sender.innerText = input.value;
document.body.appendChild(sender);
for (var i = 0; i < data.length; i++) {
if (input.value === data[i].person1) {
receiver.innerText = data[i].person2;
document.body.appendChild(receiver);
i = data.length;
} else {
receiver.innerText = "I don't understand";
document.body.appendChild(receiver);
}
}
}<input id="person">
<button onclick="SendMessage()">Send message</button>
