Checked out the example on both my devices. Everything works fine, except few things. One of them, the most annoying for user, is the alert. It looks like in 1 of 10 or even less ticks(or whatever you call it) the device cannot get my location. Even if it's so, I think it’s ok for an entertainment app.
How to disable the alert?
The simple way i can think of is to completely disable all alert by altering alert functionality when the document is "ready."
<script>
document.addEventListener('DOMContentLoaded', function(){ //equivalent to jQuery $('document').ready(function(){})
/* alert("this will show"); */
alert = function(){};
/* alert("ALL alert after this won't show"); */
}, false);
</script>

I have a django project and I want to start adding Vue.js elements into it, but there is a big overarching issue before I can really start in that custom delimiters (template tags) do not work in the firefox browser only Chrome, I can change them from curly braces to square brackets, but in firefox it just renders the code not the message. The following code is not part of my django project, it is just example code to demonstrate the issue.
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8">
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<title>Learning Vue.js</title>
</head>
<body>
<div id="app">
<input type="text" v-model="name" />
<p>Hello [[ message ]]</p>
</div>
<script>
new Vue({
delimiters: ["[[","]]"],
el: '#app',
data() {
return {
message: 'Hello World'
};
}
});
</script>
</body>
</html>
So this code renders the following in Chrome:
Hello World!
And in Firefox, it renders the code:
[[ message ]]
I'm assuming there is a fix for this, as I almost never see rendered code in websites and I'm assuming Vue is popular, how do other developers get around this issue?
I wrote the following code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
<button> Click </button>
</body>
<script>
document.getElementsByTagName('button')[0].addEventListener('click', function() {
alert('OK');
})
</script>
</html>
As you can see, the purpose of this code is launching a dialog box whenever the user clicks the 'button'.
I just started to use iMacros for Chrome, and it seems that iMacros doesn't "catch" this click.
Do you know why and how it can be resolved?
all. I'm new to foundation.
I tried to make a dropdown example, but it didn't work at all.

The browser shows the text "Has Content Dropdown", but nothing happens when I click the link.
I wonder that I must misunderstand how to use the dropdown component, but can't find what is wrong.
What's wrong with the program? Please help.

Can the following href="#" be called automatically?
<a id="loadBtn" href="#">Do stuff</a></p>
Thanks!
(Update) In the following facebook gallery launcher:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery.getfacebookalbums.js"></script>
<link rel="stylesheet" href="css/jquery.getfacebookalbums.css" type="text/css">
<script type="text/javascript">
$(document).ready(function () {
$('#loadBtn').click(function () {
$('#albumsContainer').getFacebookAlbums({
appId : 'ID',
onImageSelected : function (data) {
alert("Your facebook image is located at " + data);
window.location.href = "assignFacebookPhoto.php?fbPhoto=" + data;
}
})
return false;
});
});
</script>
<style type="text/css">
html, body {
font-family: Arial, _sans;
font-size: 0.8em;
}
</style>
</head>
<body>
<p><a id="loadBtn" href="#">Get photo</a></p>
<div id="albumsContainer"></div>
</body>
</html>
Essentially to get to the action faster rather than having msc bits of text to click first.
you can set href attribute with whatever value you want as per below code:
$('#loadBtn').attr('href','#');
Not sure whether the href='#' is just for example purposes or what you're putting in your final code.
(1) If you want to scroll to the top of the page, you can either use $('body').scrollTop(0) or animate it a bit with something like $('html, body').animate( {scrollTop : 0 }, 200); (If you want to animate it, just attach it to #loadBtn's click event and be sure to return false, so the anchor won't jump to the top and override your animation.)
If you want, you can also set window.location.hash so the hash location will be recorded.
(2) If you want to simulate a click on the link, you can use .trigger(), e.g.: $('#loadBtn').trigger('click');
I think following code will work for you:
$("#loadBtn").ready(function(){
$(this).click();
});
Also try this in your onload function:
document.getElementById('yourLinkID').click();
// Automatically href will be called
Thanks for your pointers. It lead me to the idea of just rearranging the javascript so that the code was executed without need to click anything:
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="js/jquery.getfacebookalbums.js"></script>
<link rel="stylesheet" href="css/jquery.getfacebookalbums.css" type="text/css">
<style type="text/css">
html, body {
font-family: Arial, _sans;
font-size: 0.8em;
}
</style>
</head>
<body>
<!--p><a id="loadBtn" href="#">Get photo</a></p-->
<div id="albumsContainer"></div>
<script type="text/javascript">
$('#albumsContainer').getFacebookAlbums({
appId : 'ID',
onImageSelected : function (data) {
alert("Your facebook image is located at " + data);
window.location.href = "assignFacebookPhoto.php?fbPhoto=" + data;
}
})
</script>
</body>
</html>
When I add this script to a plain HTML file's HEAD section
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>
and I run this script on the body onload,
function initialize() {
var latlng = new google.maps.LatLng(-34.397, 150.644);
var myOptions = {
zoom: 8,
center: latlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
}
then I see the Google map just fine.
However, the same does not work when in a Django template. (Yes, I am new to Django :)
I get all the code in the initialize function to run, but no map shows up. Page stays blank.
I assume it has something to do with Django, and the GAE dev server, and how the Google Maps js API is referenced, but I don't know how to fix.
Thanx much.
Edit:
My Django template looks like this (There are no Django specific tags or anything yet.)

Your DOCTYPE is causing the problem. If I remove that from your code, then the map displays.
There are some threads on the Google Maps JavaScript API v3 Group that discuss this problem.
I don't think your problem is (directly) related to the GAE development server or Django - it looks like your page's HTML is loading just fine.
I suspect your problem may be the jQuery reference. Perhaps jQuery is not being loaded, and thus your script stops executing when it tries to access $(document) but fails because a ReferenceError is thrown.
I would check that your link to load the jQuery library is working by manually accessing it in your browser (i.e., browse to http://localhost:8080/site_media/js/jquery.min.js (or wherever you are running your development server) and make sure it works). If not, then fix your app.yaml file so that it is properly setup to serve /site_media/js/jquery.min.js.
I've had this I think and I fixed it by just doing the Google Maps initialize from google's own method:
google.setOnLoadCallback(initialize);
I know I tried to do this (by default) in jQuery's ready but that didn't work for some reason.
