How do i show all the data by using the loop to display all the data from json to html ?
ATM , I am able to print one of the data. but if i am using data[i] the code will not display any data.
I think I mess up the the concept of object and array.
please advice me , how to loop thru object , like array?
thanks
var getWeather = document.getElementById('weather');
var requestWeather = new XMLHttpRequest();
//+'-31' +'&lon='+'150'
requestWeather.open('GET','https://fcc-weather-api.glitch.me/api/current?lat=-31&lon=150');
requestWeather.onload = function () {
var weatherData = JSON.parse(requestWeather.responseText);
console.log(weatherData);
getHTML(weatherData);
};
requestWeather.send();
function getHTML(data) {
var weatherString = "";
for(var i in data.weather ){
var x= data.weather[i].main;
weatherString+= "<p class='weather'>" + x + "</p>";
// weatherString+= "<p>" + data.currently.summary + "</p>";
// console.log(data[i].city);
}
getWeather.insertAdjacentHTML("beforeend", weatherString);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="weather"></div>
to get all data check for object and do recursive loop
var getWeather = document.getElementById('weather');
var requestWeather = new XMLHttpRequest();
//+'-31' +'&lon='+'150'
requestWeather.open('GET', 'https://fcc-weather-api.glitch.me/api/current?lat=-31&lon=150');

getHTML(x);
}

This is the js file. What im trying to do is create an onclick delete function when clicked on a particular row in html page. So far i can get the child key(nesting) but somehow the delete function throws error i.e career-delete.html:1 Uncaught ReferenceError: MCu9V4ypS is not defined
at HTMLButtonElement.onclick (career-delete.html:1).

var ParentKey = snapshot.key;
console.log("PK"+ParentKey);
snapshot.forEach(function(childSnapshot) {
childSnapshot.forEach(function(snap){
var childKey = snap.key;
console.log("CK" + childKey);
var Vacancy = snap.child("VacancyNumber").val();
console.log("VacancyNumber" + Vacancy);
// var NoticeNumber = snap.child("Service").val();

function Delete(key){

}
});
You can delete nodes by using the following alternative:
feedRef.set(null);
https://firebase.google.com/docs/database/web/read-and-write#delete_data
You need to add some double quotes as follows:
<button type="button" onclick="Delete('" +childKey+ "');" class="btn delete">X</button>
I'm trying to parse XML by using AJAX. However there were a few errors which i got saying my "html is not defined"
Basically what I want to do is to parse a specific amount of data from my XML codes and display it using HTML webpage .
The below is the list of bugs in console when I tried to run the script

There isn't any problem with my XML codes so it has to be some error from here.
You got that error html is not defined because you are using html variable without declaring it. So, before the line
html += "country-code: " + recordObj.countrycode;
you have to write
let html = '';
I am working on Address book using HTML,CSS and Javascript. First I am reading some data entries from a JSON file. Then storing those entries into local storage. Then I am taking input from the user in few input fields through the function called addToBook(). And then storing all the data in JSON format in the variable called addressBook. But when i am trying to print this data in the function called showaddressBook(). It is not happening as it is showing as Undefined in the chrome console. Refer to this line(console.log(addressBook[i].practice_name);) in the function showaddressBook(). Any idea guys. Thanks in advance.

console.log(addressBook[i].practice_name);
}
}
}
showaddressBook();
}
There are typo mistakes,
practice_name should be practicename
last_name should be lastname
first_name should be firstname
email_address should be email
Try:
for(var i = 0; i <addressBook.length;i++){
str += '<div id="entry">';
str += '<div id="name"><p>' + addressBook[i].lastname +', '+addressBook[i].firstname+ '</p></div>';
str += '<div id="email"><p>' + addressBook[i].email + '</p></div>';
str += '<div id="practicename"><p>' + addressBook[i].practicename + '</p></div>';
str += '<div id="specialty"><p>' + addressBook[i].specialty + '</p></div>';
str += '<div id="del">Delete</div>';
console.log(addressBook[i].practicename);
}
After using he JSON.stringify() method in JavaScript to allow JSON data render in the browser it outputs double quotations " " at either end of the property rendered in the browser - any idea how to resolve this?
Here is my code -
<li class="divider">Brown Eyes</li>
<div id="output1"></div>
<li class="divider">Green Eyes</li>
<div id="output2"></div>
<script>
var myContainer = "";
var a = new XMLHttpRequest();
a.open("GET", "https://api.myjson.com/bins/1dwnm", true);
a.onreadystatechange = function () {
console.log(a);
if (a.readyState == 4) {
var obj = JSON.parse(a.responseText);
for (i = 0; i < obj.length; i++) {
if (obj[i].eyeColor == 'brown') {
var myContainer = "<ul class='list'><li>" + obj[i].name.first + " " + obj[i].name.last + " - " + obj[i].eyeColor + "</li></ul>";
var myContainer = JSON.stringify(myContainer);
document.getElementById('output1').innerHTML += myContainer;
}
if (obj[i].eyeColor == 'green') {
var myContainer = "<ul class='list'><li>" + obj[i].name.first + " " + obj[i].name.last + " - " + obj[i].eyeColor + "</li></ul>";
var myContainer = JSON.stringify(myContainer);
document.getElementById('output2').innerHTML += myContainer;
}
}
}
}
a.send();
</script>
Because "<ul class='list'><li>Faye Garrett - brown</li></ul>" is not a valid JSON string.
Uncomment your stringify lines and it works.
I have a two part question. The first is that I tried to replace all of my document.write with innerHTML and now nothing generates on the page correctly. The second part of my question is that I can't figure out the logic on my toggleCurrent function so that I can hide show the currently displayed view. example - if the thumbnail view is visible I want to hide/show or if the full view is visible I want to hide/show that. http://jsfiddle.net/5M3k7/

Because you keep overriding the last thing entered in.
full.innerHTML = '<div class="wrap"><div class="cont">' + "Name: " + characters[i].fullName + '<br/>' + 'Age: ' + characters[i].age + '<br/>' + 'Cider: ' + characters[i].cider + '</div></div>';
You are need to append to the innerHTML
full.innerHTML = full.innerHTML + '<div class="...
