Javascript:
var hotel={
//Properties
name:'Pacific Idea',
rooms:20,
booked:15,
//Methods
checkAvailability = function () {
return this.rooms- this.booked;
}
};
var nameHotel=document.getElementById('name');
var roomHotel=document.getElementById('rooms');
var bookedHotel=document.getElementById('booked');
var availableHotel=document.getElementById('available');
nameHotel.textContent=hotel.name;
roomsHotel.textContent=hotel.rooms;
bookedHotel.textContent=hotel.booked;
availableHotel.textContent=hotel.checkAvailability();
Now according to this code, the name, number of booked rooms, number of available rooms of the hotel should be displayed. But unfortunately, it just doesn't display anything.
Please help me..
2 errors in your javascript code. one is checkAvailability = function (); should be ':' instead of '='. and roomsHotel typo error.
Try
var hotel={
//Properties
name:'Pacific Idea',
rooms:20,
booked:15,
//Methods
checkAvailability : function () {
return this.rooms- this.booked;
}
};
var nameHotel=document.getElementById('name');
var roomsHotel=document.getElementById('rooms');
var bookedHotel=document.getElementById('booked');
var availableHotel=document.getElementById('available');
nameHotel.textContent=hotel.name;
roomsHotel.textContent=hotel.rooms;
bookedHotel.textContent=hotel.booked;
availableHotel.textContent=hotel.checkAvailability();

I'm trying to create an autocomplete text field, that autocompletes the country that's filled in, if the country already exists in the google sheet. At the moment my code only works, when I write all the possible countries in the 'availabletags' variable. But I want it to get the values directly from the google sheet. This is the html & script:
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">

<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
</head>
<body>
<div class="ui-widget">
<label for="text">country</label>
<input id="text">
</div>
<div>
<button id="btn"> Run it! </button>
</div>
<script>
$(function() {
var availableTags = [ //should be changed to availableTags = list;
"belgium",
"france",
"greece",
"spain",
"italy",
"the netherlands"
];
$("#text").autocomplete({
source: availableTags
});
});
document.getElementById("btn").addEventListener("click", doStuff);
function doStuff() {
var ucountry = document.getElementById("text").value;
google.script.run.userClicked(ucountry);
document.getElementById("text").value = "";
};
</script>
</body>
</html>
I wrote following code in google script to retrieve the countries from the google script, and when I look at the log, the list of countries from the google sheet is indeed in the list variable.
function doGet() {
var ws = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Data");
var list = ws.getRange(1,1,ws.getRange("A1").getDataRegion().getLastRow(),1).getValues(); // contains countries
Logger.log(list);
var template = HtmlService.createTemplateFromFile("page");
template.list = list.map(function(r){return r[0]; });
var html = template.evaluate();
return html;
}
function userClicked(country){
var url = "https://docs.google.com/spreadsheets/d/1IMxZwN3swMTf9EoF_k3iRV7Zc6iwzoWzov5-qC_MSKU/edit#gid=0";
var ss = SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("Data");
ws.appendRow([country]);
}
I would like to have the var availableTags = list; But when I do that, the autocomplete stops working. Any help would be appreciated!
Use google.script.run with SuccessHandler
This implies the creation of an additional .gs function that will be called from clientside onload.
Sample:
Code.gs
function doGet() {
var template = HtmlService.createTemplateFromFile("page");
var html = template.evaluate();
return html;
}
function getCountry(){
var ws = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Data");
var list = ws.getRange(1,1,ws.getRange("A1").getDataRegion().getLastRow(),1).getValues(); // contains countries
list = list.map(function(r){return r[0]; });
Logger.log(list);
return list;
}
function userClicked(country){
var url = "https://docs.google.com/spreadsheets/d/1IMxZwN3swMTf9EoF_k3iRV7Zc6iwzoWzov5-qC_MSKU/edit#gid=0";
var ss = SpreadsheetApp.openByUrl(url);
var ws = ss.getSheetByName("Data");
ws.appendRow([country]);
}

I'm trying to implement a setInterval() method but I'm not sure exactly where to put it. Basically, I want this whole JavaScript script to run every minute or so. I think the code that I want to add is the one line I have added below, but I don't know exactly where to put it, and I don't know what the first parameter should be (although I know it should be the name of the function that I want to call).
setInterval(myTimer, 60000);
And here's the full code:
<!DOCTYPE html>
<html>
<head>
<title>Ethereum Tracker</title>
<link rel="stylesheet" type="text/css" href="stylesheet.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
let myData = "";
let dataTest = "";
$.get("https://api.coinmarketcap.com/v1/ticker/ethereum/", function(data, status){
myData = data[0];
document.getElementById("p1").innerHTML = (myData.price_usd);
});
});
</script>
</head>
<body>
<p id="p1"></p>
<p id="p2"></p>
<script>
var d = new Date();
document.getElementById("p2").innerHTML = 'Last updated: ' + d.toLocaleTimeString();
</script>
</body>
</html>
You would need to do something like this
<!DOCTYPE html>
<html>
<head>
<title>Ethereum Tracker</title>
<link rel="stylesheet" type="text/css" href="stylesheet.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
function update(){
let myData = "";
let dataTest = "";
$.get("https://api.coinmarketcap.com/v1/ticker/ethereum/", function(data, status){
myData = data[0];
$("#p1").html(myData.price_usd);
var d = new Date();
$("#p2").html('Last updated: ' + d.toLocaleTimeString());
});
}
$(document).ready(function(){
// run every minute
setInterval(update, 60000);
// run immediately on load
update();
});
</script>
</head>
<body>
<p id="p1"></p>
<p id="p2"></p>
</body>
</html>
Assuming you want to update the price every minute, it should look like:
$(document).ready(function(){
setInterval(updatePrice,60000);
});
function updatePrice(){
let myData = "";
let dataTest = "";
$.get("https://api.coinmarketcap.com/v1/ticker/ethereum/",
function(data, status){
myData = data[0];
document.getElementById("p1").innerHTML =(myData.price_usd);
});
}
This is the code that I want to work out, it's about AMap.com geolocation API. I want to know how to get this value (such as gLats in code) out of the function onComplete().
<!DOCTYPE html>
<html>
<head>
<title>amap</title>
<meta charset="utf-8">
<link rel="stylesheet" href="http://cache.amap.com/lbs/static/main1119.css"/>

<script type="text/javascript" src="http://cache.amap.com/lbs/static/addToolbar.js"></script>
</head>
<body>
<div id='container'></div>
<div id="tip"></div>
<div id="text"></div>
<div id="txt"></div>
<script type="text/javascript">
var map, geolocation;
map = new AMap.Map("", {
resizeEnable: true
});
map.plugin('AMap.Geolocation', function() {
geolocation = new AMap.Geolocation({
});
map.addControl(geolocation);
geolocation.getCurrentPosition();
AMap.event.addListener(geolocation, 'complete', onComplete);
AMap.event.addListener(geolocation, 'error', onError);
});
function onComplete(data) {
var str=['succsee'];
var gLngs=data.position.getLng();
var gLats=data.position.getLat();
str.push('longitude：' + data.position.getLng());
str.push('latitude：' + data.position.getLat());
document.getElementById('tip').innerHTML = str.join('<br>');
document.getElementById('text').innerHTML = str.join('<br>');
}
function onError(data) {
document.getElementById('tip').innerHTML = 'failure';
}
</script>
</body>
</html>
As I can see, you are already accessing the needed values in onComplete():
str.push('longitude：' + data.position.getLng());
str.push('latitude：' + data.position.getLat());
You cannot simply get them, onComplete is a callback that is called when the values are available. So do anything about them in onComplete, you may want to assingn them to global variables, etc, to have them easyly accessible from anywhere in code.
Assigning them to globals is the way to go.
//declare in the global scope
var gLats = null;
var gLngs = null;
...
function onComplete(data)
{
var str=['success'];
gLats=data.position.getLat();
gLngs=data.position.getLng();
...
}
I am getting "Uncaught ReferenceError: isApp is not defined" in the console,

You load your mApp.js file before your isApp.js file and both scripts are executed right away, so naturally the function isn't defined yet when mApp.js is executed.
<script src="js/mApp.js"></script>
<script src="js/isApp.js"></script>
I have an Html file like this:
<!doctype html>
<head>
<title></title>
<link rel="stylesheet" type="text/css" href="style/boxClass.css" />
<script type="text/javascript">
/* lightBox class */
function box (id1,id2) {
this.boxBackgroundDiv = document.getElementById (id1);
this.boxWorkAreaDiv = document.getElementById (id2);
}
lightBox.prototype.setBackgroundColor = function(c) {
this.boxBackgroundDiv.style.backgroundColor = c;
alert('Hello back');
};
function init (id1,id2)
{
boxObj = new box (id1,id2);
alert ("Hello");
}
</script>
</head>
<body onload="init('box1','box2')">
<div id="lightbox1" class="boxBackground">I am here</div>
<div id="lightbox2" class="boxWorkArea"><button onclick="boxObj.setBackgroundColor('Red')">I am here</button></div>
</body>
</html>
Now when I call my init function the way it is in this code via it works fine. But if I do as below via window.onload, it does not work. its not able to get the div ids in this case. But I need div ids to crate objs for my class.
<!doctype html>
<head>
<title></title>
<link rel="stylesheet" type="text/css" href="style/boxClass.css" />
<script type="text/javascript">
/* lightBox class */
function box (id1,id2) {
this.boxBackgroundDiv = document.getElementById (id1);
this.boxWorkAreaDiv = document.getElementById (id2);
}
lightBox.prototype.setBackgroundColor = function(c) {
this.boxBackgroundDiv.style.backgroundColor = c;
alert('Hello back');
};
function init (id1,id2)
{
boxObj = new box (id1,id2);
alert ("Hello");
}
window.onload = init ("box1",box2);
</script>
</head>
<body>
<div id="lightbox1" class="boxBackground">I am here</div>
<div id="lightbox2" class="boxWorkArea"><button onclick="boxObj.setBackgroundColor('Red')">I am here</button></div>
</body>
</html>
Two issues:
1) You are missing quotes around box2 parameter,
2) You are assigning the return value of init function (which here is a void) to window.onload handler.
You should assign the onload handler as below:
window.onload = function(){
init ("box1","box2");
}
