Does anyone know of a view controller for iPhone/iPad that shows a monthly calendar?

I Google a lot for showing Month View / Calendar View in my Titanium application but unable to find it out which work on IPhone and Android (Almost all the screens) Both.
After that I tried to implement it by my own and got the good implementation.
To achieve this, Create project which support Android & IPhone.
Open app.js and replace the following code with the existing code and after that Press Command + Shift + F to format the code.
// Taking Screen Width
var screenWidth = 322;
var needToChangeSize = false;
var screenWidthActual = Ti.Platform.displayCaps.platformWidth;
if (Ti.Platform.osname === 'android') {
if (screenWidthActual >= 641) {
screenWidth = screenWidthActual;
needToChangeSize = true;
}
}
// Main Window of the Month View.
var win = Ti.UI.createWindow({
backgroundColor : '#FF000000',
navBarHidden : true
});
// Button at the buttom side
var backButton = Ti.UI.createButton({
bottom : '20dp',
height : '40dp',
width : '200dp'
});
// Previous Button - Tool Bar
var prevMonth = Ti.UI.createButton({
left : '15dp',

});
// Next Button - Tool Bar
var nextMonth = Ti.UI.createButton({

});
// Month Title - Tool Bar
var monthTitle = Ti.UI.createLabel({

Tested Environment
Titanium Studio - 2.1.2.201208301612
Titanium SDK - 2.1.0.GA
Android - 2.2 Emulator
iOS Version - 5.0
Reference - http://titaniumexplorers.blogspot.in/2012/09/titanium-calendar-month-view.html

There is no in-built view controller for that. You will need to create your own. There are projects in Github for that exact purpose.
Check these out.

While horizontal scrolling the datalabels of charjs is overlapping to y-axis

To show all bars I have set the horizontal scrolling to chartjs in Ionic angular project , and i have used the DataLabelsPlugin constant for bars label. and while scrolling the datalabels is overlapping with y-axis its not hiding before y-axis like bars.
and also horizontal scroll is not happening smoothly.
graph working fine as a expected output
marked with issue about - after scrolling the datalabels went over the y-axis not hide below y-axis like bars
I have tried to add and used the custom datalabels but same issue i am getting and i didnt find any css or attribute on 'https://www.chartjs.org/docs/latest/' official site or not on any other sites -> to hide the datalabels from over the y-axis.
ts file code:
createBarChart() {
const footer = (tooltipItems) => {
let sum = 0;
tooltipItems.forEach(function(tooltipItem) {
sum += tooltipItem.parsed.y;

return "";

const toolTitle = (tooltipItems) => {
var string_to_array = function (str) {

Dygraphs - How do I restrict drawing to canvas

I have a graph where I am using underlays to draw vertical lines between the points. I have a line of code that restricts these vertical lines to NOT draw outside the active canvas. But when I use this underlayCallback, the 'points' are still drawn outside the canvas. If I remove my underlayCallback, the points are restricted to the canvas as one would expect. Here is what they look like and my code. (Sorry, the site is too secure to provide working sample.)
g[i] = new Dygraph(thisdiv, mylines, {
labels: graphlbls[i],
ylabel: graphunits[i].capitalizeFirstLetter(),
xlabel: '',
xLabelHeight:15,
yLabelWidth:15,
rightGap: 5,
labelsDivStyles: {
'text-align': 'right',
'background': 'none'
},
colors: ['#D48513','#1D6EB5'],
title: graphtitles[i],
titleHeight:23,
drawPoints: true,
showRoller: false,
drawXGrid: false,
drawYGrid: true,
strokeWidth: 0,
pointSize: 4,
highlightCircleSize: 6,
gridLineColor: "#ddd",
axisLabelFontSize: 12,
xAxisHeight: 20,
valueRange: [minval, maxval],
rangeSelectorHeight: 30,
showRangeSelector: true,
rangeSelectorPlotFillColor: '#ffffff',
rangeSelectorPlotStrokeColor: '#ffffff',
interactionModel: Dygraph.defaultInteractionModel,
axes: {
x: {
valueFormatter: function (ms) {
var d = new Date(ms);
var day = "0"+d.getDate();
var month = "0"+(d.getMonth()+1);
var year = d.getFullYear();
var hour = "0"+ d.getHours();
var min = "0"+d.getMinutes();
var p = "AM";
if (hour > 12) { p = "PM"; hour = hour - 12; }
if (df == 0) var dd = month.slice(-2)+"/"+day.slice(-2)+"/"+year;
if (df == 1) var dd = day.slice(-2)+"/"+month.slice(-2)+"/"+year;
if (tf == 0) var tt = hour.slice(-2)+":"+min.slice(-2)+" "+p+" ";
if (tf == 1) var tt = hour.slice(-2)+":"+min.slice(-2)+" ";
return dd + " - " + tt;
}
}
},
underlayCallback: function(ctx, area, g) {
//if (typeof(g[i]) == 'undefined') return; // won't be set on the initial draw.
var range = g.xAxisRange();
var rows = g.numRows();
// get max and min y
for (var i = 0; i < rows; i++) {
miny = 99999;
maxy = -99999;
xx = g.getValue(i,0);
if (xx < range[0] || xx > range[1]) continue; // constrain to graph canvas
for (var j=1; j<= range.length; j++) {
if (g.getValue(i,j) <= miny) miny = g.getValue(i,j);
if (g.getValue(i,j) >= maxy) maxy = g.getValue(i,j);
}
p1 = g.toDomCoords(xx, miny);
p2 = g.toDomCoords(xx, maxy);
ctx.strokeStyle = "rgba(192,192,224,1)";
ctx.lineWidth = 1.0;
ctx.beginPath();
ctx.moveTo(p1[0], p1[1]);
ctx.lineTo(p2[0], p2[1]);
ctx.closePath();
ctx.stroke();
ctx.restore();
}
}
});
You're calling ctx.restore() many times without corresponding calls to ctx.save(). This pops off dygraphs' own drawing context, including the clipping rectangle. Make one call to save at the top of your underlayCallback and one to restore at the end.
Stepping back a bit, what you're doing might be easier with a custom plotter, rather than an underlayCallback.

How to implement auto complete in Smartface App Studio

I am developing an iOS app with Smartface App Studio. I need to implement an search with auto complete. Can any suggest to achieve this.
Ex: If user typing "Ho" then list of places starts with "Ho" like "Holland", "Hong Kong" need to show as suggestions(while typing).
I tried with pick() and label on page. But that is working as dropdown.
Thanks in advance.
After alot work around, i made my autocomplete functinlity. Here is the code.
function PrepareAutoComplete(page, pageName) {
try {
var label_for_repeatbox = new SMF.UI.Label({
height : '100%',
width : '100%',
horizontalGap : 10,
left : '0%',
top : '0%',
fontColor : SMF.UI.Color.black,
backgroundTransparent : true
});
var rBox = new SMF.UI.RepeatBox({
name : 'rptDestinations',
width : '100%',
height : '90%',
left : Pages.PlacesToGo.edtBoxSelectDestination.left,
top : Pages.PlacesToGo.edtBoxSelectDestination.top + Pages.PlacesToGo.edtBoxSelectDestination.height + 1,
borderWidth : 1,
dataSource : [],
showScrollbar : true,
onRowRender : function onRowRender(e) {
this.controls[0].text = e.rowData;
},
itemTemplate : {
height : '10%'
}
});
label_for_repeatbox.onTouchEnded = function (e) {
alert(this.text);
}
rBox.useActiveItem = true;
rBox.visible = false;
rBox.itemTemplate.add(label_for_repeatbox);
Pages.PlacesToGo.edtBoxSelectDestination.onChange = function (e) {
if (this.text.length > 1 && isFirstTime == false) {
var search_key = this.text.toLowerCase();
var results = [];
for (var i = 0; i < Sources.length; i++) {
if (Sources[i].toLowerCase().indexOf(search_key) == 0) {
results.push(Sources.[i]);
}
}
rBox.dataSource = results;
rBox.refresh();
page.remove(rBox);
page.add(rBox);
rBox.visible = true;
}
}
Pages.PlacesToGo.edtBoxSelectDestination.onExit = function () {
rBox.dataSource = [];
rBox.refresh();
rBox.visible = false;
}
page.add(rBox);
} catch (ex) {

Here is my code, as you can see I am having calling the Facebook api graph iterating through every album, and then detecting the profile album. The problem with this approach is that if the user has a 1000 albums, the for loop can take forever to find the profile album.
Anyone know of a quicker way to do this?
Cheers
Currently there is no such mechanism available in Graph API.
Also, your proposed method is unreliable at best, since not everybody uses Facebook in the English language, and for those that don't, the album might not be called "Profile Pictures".
The best way to get a user's current profile picture (without the album) is by fetching /user/picture

jsPDF multi page PDF with HTML renderer

I am using jsPDF in my site to generate PDFs. But now I have multiple DIVs to print in a single PDF. which may take 2 to 3 pages.
For example:
<div id="part1">
content
</div>
<div id="part2">
content
</div>
<div id="part2">
content
</div>
my JS code
This works but not as I expected, It add a part of the content(which cannot be included in more than one page).
It removes html tags like br, h1 etc.
function formtoPDF() {
jsPDF.API.mymethod = function() {
// 'this' will be ref to internal API object. see jsPDF source
// , so you can refer to built-in methods like so:
// this.line(....)
// this.text(....)
};
var doc = new jsPDF();
doc.mymethod();
var pdfPart1 = jQuery('#genPDFpart1');
var pdfPart2 = jQuery(".ltinerary");
var pdfPart3 = jQuery("#domElementHTML");
var specialElementHandlers = {
'#loadVar': function(element, renderer) {
return true;
}
};
doc.fromHTML(pdfPart1.html() + pdfPart3.html() + pdfPart3.html(), 15, 15, {
'width': 170,
'elementHandlers': specialElementHandlers
});
doc.output('save', 'Download.pdf');
}
What's the solution for this?
I have the same working issue. Searching in MrRio github I found this: https://github.com/MrRio/jsPDF/issues/101
Basically, you have to check the actual page size always before adding new content
doc = new jsPdf();
...
pageHeight= doc.internal.pageSize.height;
// Before adding new content
y = 500 // Height position of new content
if (y >= pageHeight)
{
doc.addPage();
y = 0 // Restart height position
}
doc.text(x, y, "value");
here's an example using html2canvas & jspdf, although how you generate the canvas doesn't matter--we're just going to use the height of that as the breakpoint on a for loop, in which a new page is created and content added to it.
after the for loop, the pdf is saved.
function makePDF() {
var quotes = document.getElementById('container-fluid');
html2canvas(quotes).then((canvas) => {
//! MAKE YOUR PDF
var pdf = new jsPDF('p', 'pt', 'letter');
for (var i = 0; i <= quotes.clientHeight/980; i++) {
//! This is all just html2canvas stuff
var srcImg = canvas;
var sX = 0;
var sY = 980*i; // start 980 pixels down for every new page
var sWidth = 900;
var sHeight = 980;
var dX = 0;
var dY = 0;
var dWidth = 900;
var dHeight = 980;
window.onePageCanvas = document.createElement("canvas");
onePageCanvas.setAttribute('width', 900);
onePageCanvas.setAttribute('height', 980);
var ctx = onePageCanvas.getContext('2d');
// details on this usage of this function:
// https://developer.mozilla.org/en-US/docs/Web/API/Canvas_API/Tutorial/Using_images#Slicing
ctx.drawImage(srcImg,sX,sY,sWidth,sHeight,dX,dY,dWidth,dHeight);
// document.body.appendChild(canvas);
var canvasDataURL = onePageCanvas.toDataURL("image/png", 1.0);
var width = onePageCanvas.width;
var height = onePageCanvas.clientHeight;
//! If we're on anything other than the first page,
// add another page
if (i > 0) {
pdf.addPage(612, 791); //8.5" x 11" in pts (in*72)
}
//! now we declare that we're working on that page
pdf.setPage(i+1);
//! now we add content to that page!
pdf.addImage(canvasDataURL, 'PNG', 20, 40, (width*.62), (height*.62));
}
//! after the for loop is finished running, we save the pdf.
pdf.save('Test.pdf');
});
}
I found the solution on this page: https://github.com/MrRio/jsPDF/issues/434
From the user: wangzhixuan
I copy the solution here:
// suppose your picture is already in a canvas
var imgData = canvas.toDataURL('image/png');
/*
Here are the numbers (paper width and height) that I found to work.
It still creates a little overlap part between the pages, but good enough for me.
if you can find an official number from jsPDF, use them.
*/
var imgWidth = 210;
var pageHeight = 295;
var imgHeight = canvas.height * imgWidth / canvas.width;
var heightLeft = imgHeight;
var doc = new jsPDF('p', 'mm');
var position = 0;
doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
heightLeft -= pageHeight;
while (heightLeft >= 0) {
position = heightLeft - imgHeight;
doc.addPage();
doc.addImage(imgData, 'PNG', 0, position, imgWidth, imgHeight);
heightLeft -= pageHeight;
}
doc.save( 'file.pdf');
var doc = new jsPDF('p', 'mm');
var imgData = canvas.toDataURL('image/png');
var pageHeight= doc.internal.pageSize.getHeight();
var pageWidth= doc.internal.pageSize.getWidth();
var imgheight = $('divName').height() * 25.4 / 96; //px to mm
var pagecount = Math.ceil(imgheight / pageHeight);
/* add initial page */
doc.addPage('l','mm','a4');
doc.addImage(imgData, 'PNG', 2, 0, pageWidth-4, 0);
/* add extra pages if the div size is larger than a a4 size */
if (pagecount > 0) {
var j = 1;
while (j != pagecount) {
doc.addPage('l','mm','a4');
doc.addImage(imgData, 'PNG', 2, -(j * pageHeight), pageWidth-4, 0);
j++;
}
}
You can use html2canvas plugin and jsPDF both. Process order:
html to png & png to pdf
Example code:
jQuery('#part1').html2canvas({
onrendered: function( canvas ) {
var img1 = canvas.toDataURL('image/png');
}
});
jQuery('#part2').html2canvas({
onrendered: function( canvas ) {
var img2 = canvas.toDataURL('image/png');
}
});
jQuery('#part3').html2canvas({
onrendered: function( canvas ) {
var img3 = canvas.toDataURL('image/png');
}
});
var doc = new jsPDF('p', 'mm');
doc.addImage( img1, 'PNG', 0, 0, 210, 297); // A4 sizes
doc.addImage( img2, 'PNG', 0, 90, 210, 297); // img1 and img2 on first page
doc.addPage();
doc.addImage( img3, 'PNG', 0, 0, 210, 297); // img3 on second page
doc.save("file.pdf");
$( document ).ready(function() {
$('#cmd').click(function() {
var options = {
pagesplit: true //include this in your code
};
var pdf = new jsPDF('p', 'pt', 'a4');
pdf.addHTML($("#pdfContent"), 15, 15, options, function() {
pdf.save('Menu.pdf');
});
});
});
This is my first post which support only a single page http://www.techumber.com/html-to-pdf-conversion-using-javascript/
Now, the second one will support the multiple pages.
http://www.techumber.com/how-to-convert-html-to-pdf-using-javascript-multipage/
Below is my code but the problem is that the document doesn't split to display the other part of the document in a new page.
Please improve this code.
<script type='text/javascript'>
$(document).on("click", "#btnExportToPDF", function () {
var table1 =
tableToJson($('#table1')[0]),

var doc = new jsPDF(l,'pt', 'letter');

});
function tableToJson(table) {

// first row needs to be headers
var headers = [];

}

return data;

</script>
Automatically not split data to multi pages. You may split manually.
If your ( rowCount * rowHeight ) > 420mm ( A3 Height in mm ) add new page function. ( Sorry I can't edit your code without run )
After add new page leftMargin, topMargin = 0; ( start over )
I added sample code with yours. I hope it's right.
else {
doc.margins = 1;
doc.setFont("Times ");
doc.setFontType("normal ");
doc.setFontSize(11);
if ( rowCount * rowHeight > 420 ) {
doc.addPage();
rowCount = 3; // skip 1 and 2 above
} else {
// now rowcount = 3 ( top of new page for 3 )
// j is your x axis cell index ( j start from 0 on $.each function ) or you can add cellCount like rowCount and replace with
// rowcount is your y axis cell index
left = ( ( j ) * ( cellWidth + leftMargin );
top = ( ( rowcount - 3 ) * ( rowHeight + topMargin );
doc.cell( leftMargin, top, cellWidth, rowHeight, cellContent, i);
// 1st=left margin 2nd parameter=top margin, 3rd=row cell width 4th=Row height
}
}
You can convert html directly to pdf lossless. Youtube video for html => pdf example
html2canvas(element[0], {
onrendered: function (canvas) {
pages = Math.ceil(element[0].clientHeight / 1450);
for (i = 0; i <= pages; i += 1) {
if (i > 0) {
pdf.addPage();
}
srcImg = canvas;
sX = 0;
sY = 1450 * i;
sWidth = 1100;
sHeight = 1450;
dX = 0;
dY = 0;
dWidth = 1100;
dHeight = 1450;
window.onePageCanvas = document.createElement("canvas");
onePageCanvas.setAttribute('width', 1100);
onePageCanvas.setAttribute('height', 1450);
ctx = onePageCanvas.getContext('2d');
ctx.drawImage(srcImg, sX, sY, sWidth, sHeight, dX, dY, dWidth, dHeight);
canvasDataURL = onePageCanvas.toDataURL("image/png");
width = onePageCanvas.width;
height = onePageCanvas.clientHeight;
pdf.setPage(i + 1);
pdf.addImage(canvasDataURL, 'PNG', 35, 30, (width * 0.5), (height * 0.5));
}
pdf.save('testfilename.pdf');
}
});
var a = 0;
var d;
var increment;
for(n in array){
d = a++;
if(n % 6 === 0 && n != 0){
doc.addPage();
a = 1;
d = 0;
}
increment = d == 0 ? 10 : 50;
