I cannot see what is wrong with this code. Calculate center position of window then transform-translate div there (have to use translate for what i am doing).
Just getting this working for Chrome for a start, hence the -webkit- prefix).
Very confused as to why jQuery does not apply the inline style to the .logo div. Have included my other trouble-shooting experiments, commented out.
A syntax problem? jsfiddle here.
var centerPosition = '';
function centerLogo(){
var w_width = $(window).width();
var w_height = $(window).height();
var hCenter = (w_width / 2) - 150;
var vCenter = (w_height / 2) - 150;
console.log(hCenter);
console.log(vCenter);
var centerPosition = 'translate(' + hCenter + 'px, ' + vCenter + 'px);';
console.log(centerPosition);
$('.logo').css('-webkit-transform', centerPosition);
// Try uncommenting the three examples below - they all work ...
// $('.logo').css('background', 'blue');
// centerPosition = 'blue';
// $('.logo').css('background', centerPosition);
// $('.logo').css('-webkit-transform', 'translate(10.85px, 45.56px)');
}
jQuery(document).ready(function($){
centerLogo();
});
The correcy syntax of $('.logo').css('-webkit-transform', centerPosition); does not have semi colons inside the Strings. Try changing this:
var centerPosition = 'translate(' + hCenter + 'px, ' + vCenter + 'px);';
to this:
var centerPosition = 'translate(' + hCenter + 'px, ' + vCenter + 'px)';
Should work: http://jsfiddle.net/7f7rt/6/
This Will Sure Work.
var posElem = document.getElementById('logo'); // set id to div
var newStyle = '-webkit-transform: translate(' + hCenter + 'px, ' + vCenter + 'px);' +
'transform: translate(' + hCenter + 'px, ' + vCenter + 'px);';
posElem.setAttribute('style',newStyle);

I'm trying to add css from my controller because I need to pass some data that I calculate in it, but I don't know if it's possible, I can only find the syntax with javascript but spaui5 doesn't support it. What I'm trying to do is the following:
var horaHand = that.getView().byId("horaHand");
var minutoHand = that.getView().byId("minutoHand");
var segundoHand = that.getView().byId("segundoHand");
var manillahora = hora + minuto/12;
horaHand.css("transform", "rotate(" + manillahora + "deg)");
minutoHand.css("transform", "rotate(" + minuto + "deg)");
segundoHand.css("transform", "rotate(" + segundo + "deg)");
but it doesn't work. Is there any way I can apply this css?
The original javascript code I'm trying is this:
const hourHand = document.querySelector('#hourHand');
const minuteHand = document.querySelector('#minuteHand');
const secondHand = document.querySelector('#secondHand');
hourHand.style.transform = `rotateZ(${(hours)+(minutes/12)}deg)`;
minuteHand.style.transform = `rotateZ(${minutes}deg)`;
secondHand.style.transform = `rotateZ(${seconds}deg)`;
or this
$('.hour-hand').css({
'transform': `rotate(${hourDegrees}deg)`
});
$('.minute-hand').css({
'transform': `rotate(${minuteDegrees}deg)`
});
$('.second-hand').css({
'transform': `rotate(${secondDegrees}deg)`
});
I solved the problem like this:
$(".hora").css("transform", "rotate(" + hourDegrees + "deg)");
$(".minuto").css("transform", "rotate(" + minuteDegrees + "deg)");
$(".segundo").css("transform", "rotate(" + secondDegrees + "deg)");
but as everybody know, SAPUI5 css only works if you put !important, because of this the code above didn't work. Do you know how can I put put !important in the code in the controller? I tried like this: $(".hora").css("transform", "rotate(" + hourDegrees + "deg) !important"); but doesn't work.
I'm having trouble getting the correct mouse coordinates on the canvas after preforming pan or zoom.
I have this code for sampling coordinates and RGB:
canvas1.on('mouse:move', function (e) {
//allowing pan only if the image is zoomed.
if (panning && e && e.e) {
var delta = new fabric.Point(e.e.movementX, e.e.movementY);
canvas1.relativePan(delta);
} else {//Read the RGB value of the mouse point
var mouse = canvas1.getPointer(e.e);
var x = parseInt(mouse.x);
var y = parseInt(mouse.y);
// get the color array for the pixel under the mouse
var px = ctx.getImageData(x, y, 1, 1).data;
// report that pixel data
results.innerHTML = 'At [' + x + ' / ' + y + ']: Red/Green/Blue/Alpha = [' + px[0] + ' / ' + px[1] + ' / ' + px[2] + ' / ' + px[3] + ']';
}
});
problem is that after zoom/pan the coordinates are 'wrong',
for example the top left corner in not (0, 0) but (-someX, -someY)...
any help will be appreciated
EDIT: I've found the mistake,
this will fix it. hope it will be useful for someone else
var x = e.e.offsetX;//parseInt(mouse.x);
var y = e.e.offsetY;//parseInt(mouse.y);
This code solves it,
Hope it could be useful for others.
canvas1.on('mouse:move', function (e) {
//allowing pan only if the image is zoomed.
if (panning && e && e.e) {
var delta = new fabric.Point(e.e.movementX, e.e.movementY);
canvas1.relativePan(delta);
} else {//Read the RGB value of the mouse point
var mouse = canvas1.getPointer(e.e);
var x = e.e.offsetX;//parseInt(mouse.x);
var y = e.e.offsetY;//parseInt(mouse.y);
// get the color array for the pixel under the mouse
var px = ctx.getImageData(x, y, 1, 1).data;
// report that pixel data
results.innerHTML = 'At [' + x + ' / ' + y + ']: Red/Green/Blue/Alpha = [' + px[0] + ' / ' + px[1] + ' / ' + px[2] + ' / ' + px[3] + ']';
}
});
The penultimate line gives an "Invalid argument" error in IE11 - other browsers are fine run the code fine.
var active = $('.interactivemap-minimap-active', this.el);
if (x === undefined) x = self.x;
if (y === undefined) y = self.y;
var width = Math.round(self.container.width() / self.contentWidth / self.scale * this.el.width()),
height = Math.round(self.container.height() / self.contentHeight / self.scale * this.el.height()),
top = Math.round(-y / self.contentHeight / self.scale * this.el.height()),
left = Math.round(-x / self.contentWidth / self.scale * this.el.width()),
right = left + width,
bottom = top + height;
console.log("pass2: width=" + width + ", height=" + height + ", top=" + top + ", left=" + left + ", right=" + right + ", bottom=" + bottom);
active.each(function() {
$(this)[0].style.clip = 'rect(' + top + 'px, ' + right + 'px, ' + bottom + 'px, ' + left + 'px)';
});
the console.log will show:
width=Nan , height=Nan , top=Nan , left=Nan , right=Nan , bottom=Nan
If I comment out the troublesome line, the console.log will show:
width=Nan , height=Nan , top=Nan , left=Nan , right=Nan , bottom=Nan
width=140 , height=162 , top=-1 , left=0 , right=140 , bottom=161
So it looks like it takes a moment to populate those variables with actual data but it starts the last function when the are still equal to Nan and then errors.
Is there any way to get around this?
I'm trying to scale my SVG with g.animate({ transform: "s2.5,2.5," + bbox.cx + "," + bbox.cy }, 0); and then animate wheelAnimation(bbox.cx, bbox.cy, 1500);
var i = 0;
function wheelAnimation(cx, cy, speed){
i++;
g.animate(
{ transform: "r360," + cx + ',' + cy}, // Basic rotation around a point. No frills.
speed, // Nice slow turning rays
function(){
if(i == 5)
speed = 5000;
g.attr({ transform: 'rotate(0 ' + cx + ' ' + cy}); // Reset the position of the rays.
wheelAnimation(cx,cy, speed); // Repeat this animation so it appears infinite.
}
);
}
But my SVG didn't scaling. It's only rotates. If I remove rotation - SVG scaling. How to combine it to immediately scale and then animate rotation?
Plunker example
I've never used Snap.svg but you might try this:
var i = 0;
function wheelAnimation(cx, cy, speed, scale){
i++;
g.attr({ transform: "r0 " + cx + " " + cy + " s" + scale + "," + scale + "," + cx + "," + cy }); //Reset + Scale setup
g.animate({
transform: "r360," + cx + "," + cy + " s" + scale + "," + scale + "," + cx + "," + cy }, // Basic rotation around a point. No frills.
speed, // Nice slow turning rays
function(){
if(i == 5)
speed = 5000;
wheelAnimation(cx, cy, speed, scale); // Repeat this animation so it appears infinite.
}
);
}
Hope this helps you :)

I have a function that pops up window in the center and I want it to have a vertical scrollbar.
function popUpCal()
{
var url = "calendar_flight_maint.php";
var width = 700;
var height = 600;
var left = parseInt((screen.availWidth/2) - (width/2));
var top = parseInt((screen.availHeight/2) - (height/2));
var windowFeatures = "width=" + width + ",height=" + height + ",status,resizable,left=" + left + ",top=" + top + "screenX=" + left + ",screenY=" + top;
window.open(url, "subWind", windowFeatures, "POS", "toolbar=no", "scrollbars=1");
}
I have tried scrollbars=yes, scrollbars=auto, scrollbars=1 but the scrollbars still aren't appearing. Is there something wrong with my code? I'm using Firefox 21.0 and I've already tested it in IE 8. What seems to be the problem?
As seen in the specs for window.open, your parameters are wrong.
Try this:
function popUpCal()
{
var url = "calendar_flight_maint.php";
var width = 700;
var height = 600;
var left = parseInt((screen.availWidth/2) - (width/2));
var top = parseInt((screen.availHeight/2) - (height/2));
var windowFeatures = "width=" + width + ",height=" + height +
",status,resizable,left=" + left + ",top=" + top +
"screenX=" + left + ",screenY=" + top + ",scrollbars=yes";
window.open(url, "subWind", windowFeatures, "POS");
}
