I have created a progress bar to download images. All work fine just would like to show the download status of all files rather than individual.
var xhrList = [];
var link = [];
$('img').each(function() {
link.push($(this).attr("src"));
});
var width = $('.logo img').width();
$('#logo').css({'width': 0, 'overflow': 'hidden'});
for (var i=0; i< link.length; i++){
xhrList[i] = new XMLHttpRequest();
xhrList[i].open('GET', link[i], true);
xhrList[i].responseType = "blob";
console.log(xhrList[i]);
xhrList[i].onprogress = function(e) {
if (e.lengthComputable) {
ProgressPerc = parseInt((e.loaded / e.total) * 100);
$('#logo').stop().animate({'width': ProgressPerc + '%'},200);}
};
xhrList[i].send();
}

Below are my snippet right now its printing all canvas in single page. I want to print the each canvas in a new page.
I have use Fabricjs to render the canvas from json. Other pdf library not able to print the canvas it download empty PDF so i try JSPDF But stuck in a point.
DEMO
<script>
var jsPDF = window.jspdf.jsPDF;
var html2canvas = window.html2canvas;
function downloadpdf(){
console.log('Inside downloadpdf ');
var quotes = document.getElementById('generatePDF');
html2canvas(quotes, {
onrendered: function(canvas) {
canvas.getContext('2d');
var HTML_Width = canvas.width;
var HTML_Height = canvas.height;
var top_left_margin = 15;
var PDF_Width = HTML_Width+parseInt(top_left_margin*2);
var PDF_Height = parseInt(PDF_Width*1.5)+parseInt(top_left_margin*2);
var canvas_image_width = HTML_Width;
var canvas_image_height = HTML_Height;
var totalPDFPages = Math.ceil(HTML_Height/PDF_Height)-1;
var pages = $('#generatePDF .canvas-container').length;
console.log('height => '+canvas.height+" width => "+canvas.width+'totalpage => '+pages);
var imgData = canvas.toDataURL("image/jpeg", 1.0);
var pdf = new jsPDF('p', 'pt', [PDF_Width, PDF_Height]);
pdf.addImage(imgData, 'JPG', top_left_margin, top_left_margin,canvas_image_width,canvas_image_height);
for (var i = 1; i <= pages; i++) {
//pdf.addPage(PDF_Width, PDF_Height);
pdf.addPage();
let margin=-parseInt(PDF_Height*i)+parseInt(top_left_margin*4);
if(i>1){
margin= parseInt(margin+i*8);
}
pdf.addImage(imgData, 'JPG', top_left_margin, margin,canvas_image_width,canvas_image_height);
}
pdf.save("HTML-Document.pdf");
}
});
}

i am new to programming.. i have this code which gives distance between two points but need to further multiply it by an integer say 10.. the project i am working on is abt calculating distance between two points and multiplying it with fare/Km like Rs.10/km (Indian Rupees) for the same. So if the distance is 30 km the fare would be 30*10 = Rs.300
Thanks in advance
following is the code

I use an Ajax call to PHP, and haven't yet used getDistanceMatrix(), but this should be an easy fix.
First, if you know you will always only have one origin and one destination, you don't need the "for" loop in your callback function. Second, you're taking the distance text rather than the distance value.
function callback(response, status) {
if (status != google.maps.DistanceMatrixStatus.OK) {
[...]
} else {
deleteOverlays();
var outputDiv = document.getElementById('outputDiv'),
origin = response.originAddresses[0],
destination = response.destinationAddresses[0],
result = response.rows[0].elements[0],
distance = result.distance.value,
text = result.distance.text,
price = 10 * distance;
outputDiv.innerHTML = '<p>' + text + ': Rs.' + price + '</p>';
addMarker(origin, false);
addMarker(destination, false);
}
}
I haven't tested this, so it probably needs to be tweaked. ( See https://developers.google.com/maps/documentation/distancematrix/#DistanceMatrixResponses )
To start off with, I would like to say that I have been looking on the internet for a really long time and have been unable to find the answer, hence my question here.
My latest school project is to create an admin page for adding articles to a database, the articles are connected to a point on a google map. The requirement for adding the point on the map is that the user is able to click the map once and the marker is produced, if the map is clicked a second time the first marker is moved to the second location. (this is what I am struggling with.)
The problem is, as the code is now, I get the error that markersArray is undefined. If I place the var markersArray = new Array; underneath the eventListener then I get an error that there is something wrong the main.js (googles file) and markersArray[0] is undefined in the second if.
By the way, I have to use google maps API v2, even though it is old.
<script type="text/javascript">
//<![CDATA[

}
});
}

}
}
else if (this.counter == 1) {

I solved the problem. I'm not exactly sure why it worked but this is what it looks like now:
var markersArray = [];
function load() {
if (GBrowserIsCompatible()) {
this.counter = 0;
this.map = new GMap2(document.getElementById("map"));
this.map.addControl(new GSmallMapControl());
this.map.addControl(new GMapTypeControl());
this.map.setCenter(new GLatLng(57.668911, 15.203247), 7);
GDownloadUrl("genxml.php", function(data) {
var xml = GXml.parse(data);
var Articles = xml.documentElement.getElementsByTagName("article");
for (var i = 0; i < Articles.length; i++) {
var id = Articles[i].getAttribute("id");
var title = Articles[i].getAttribute("title");
var text = Articles[i].getAttribute("text");
var searchWord = Articles[i].getAttribute("searchWord");
var type = Articles[i].getAttribute("type");
var point = new GLatLng(parseFloat(Articles[i].getAttribute("lat")),
parseFloat(Articles[i].getAttribute("lng")));
var article = createMarker(point, id, title, text);
this.map.addOverlay(article);
}
});
}
var myEventListener = GEvent.bind(this.map,"click", this, function(overlay, latlng) {
var marker = new GMarker(latlng);
if (this.counter == 0) {
if (latlng) {
latlng1 = latlng;
this.map.addOverlay(marker);
markersArray.push(marker);
this.counter++;
}
}
else if (this.counter == 1) {
if (latlng){
this.map.removeOverlay(markersArray[0]);
this.map.addOverlay(marker);
this.counter++;
}
}
});
}
function createMarker(point, id, title, text) {
var article = new GMarker(point);
var html = "<b>" + title + "</b> <br/>"

I am trying to fill remote data into picker, but it crashes.
here is the code:
var countryDataArray = [];
var picker_country = Ti.UI.createPicker
({
bottom:'-251dp'
});
win.add(picker_country);
getCountryList(); //to call web service
//Gets country list from the server
function getCountryList()
{
getCountry.onload = function()
{
var jsonString = JSON.parse(this.responseText);
var msg = jsonString.Message;
var success = jsonString.IsSuccess;
countryDataArray = jsonString.dsetData.CountryList;
Ti.API.log('countryList value:'+countryDataArray);
activity.hide();
if(countryDataArray.length > 0)
{
for (var i=0; i < countryDataArray.length ; i++)
{
data[i] = Ti.UI.createPickerRow(
{
title:countryDataArray[i].Name,
country_id:countryDataArray[i].ID,
fontSize:18
});
};
}
picker_country.add(data);
}
what's wrong with this code ? code works fine with static data !!!
static data :-
var data = [
{title:'Bananas',custom_item:'b',fontSize:18},
{title:'Strawberries',custom_item:'s',fontSize:20},
{title:'Mangos',custom_item:'m',fontSize:22,selected:true},
{title:'Grapes',custom_item:'g',fontSize:24}
];
Solved !!! I Don't why but I just assign the data to picker before adding the picker into the view and it get solved !
picker_country.add(data);
win.add(picker_country);
i'm getting a JSON response properly but my problem is with showing it. what's wrong with my code.
// this sets the background color of the master UIView (when there are no windows/tab groups on it)
Titanium.UI.setBackgroundColor('#000');
// create base UI tab and root window
var win1 = Titanium.UI.createWindow({
title : 'Main Window',
backgroundColor : '#fff'
});
var listUrl = "http://magadhena.com/test/list.php?FCODE=5&USERID=1";
var NumberOfLists = [];
var lists;
var tableData = [];
var table = Ti.UI.createTableView({
top : 40,
left : 10,
width : 300
});
var txt1 = Titanium.UI.createTextField({
top : 10,
left : 10,
width : 250
});
var button1 = Ti.UI.createButton({
top : 10,
left : 270,
width : 30
});
var xhr = Ti.Network.createHTTPClient();
xhr.setTimeout(3000);
xhr.onload = function() {
lists = eval('(' + this.responseText + ')');
for(var i = 0; i < lists.length; i++) {
var userId = lists[i].userid;
// The userID
var listId = lists[i].listid;
// The ListID
var listName = lists[i].listname;
// The ListName
var Object1 = new list(userId, listId, listName);
// Ti.API.log("Object is ",Object1.listId);
NumberOfLists.push(Object1);
// Ti.API.log("the size of the Json array is" , NumberOfLists.length);
}
};
xhr.open("GET", listUrl);
xhr.send();
for(var i = 0; i < NumberOfLists.length; i++) {
var row = Ti.UI.createTableViewRow({
title : NumberOfLists[i].listName
});
Ti.API.log("populating the data table ", NumberOfLists[i].toString);
tableData.push(row)
};
// Ti.API.log("the size of table data is ", tableData.length);
table.setData(tableData);
win1.add(table);
win1.add(txt1);
win1.add(button1);
// Opening Window1
win1.open();
///// List Objects
function list(userid, listid, listname) {
this.userId = userid;
this.listId = listid;
this.listName = listname;
}
You need to put table.setData() into xhr.onload function. Since you defined the code outside of the function, NumberOfLists is empty until xhr.onload function executed
