I refered How to make a paper draggable, however I am stuck at initiate the paper dragging.
I am able to get the handlers and the div as mentioned in the above post, Could you please help in initiating the paper drag.
Code I have tried so far
var draggable;
paper.on('blank:pointerdown', function(evt, x, y) {
draggable=true;
});
$("#paper").on("mousemove", function(e) {
if(draggable){
//Make paper draggable and scrollable.
}
});
paper.on('blank:pointerup', function(evt, x, y) {
draggable=false;
});
Many Thanks

I want to implement an undo action for the movement of the rectangles.
For that i need the initial position of the rectangle.
I tryed with "pointerdown", but this fires also when a rectangle is just selected and not moved.
Is there a way to save the position only when movement starts?
Thank you!
You can use the Rappid's dia.CommandManager to travel the history. This includes elements movements.
CommandManager keeps track of graph changes and allows you to travel
the history of those changes back and forth. There is no limitation
put into the number of levels one can undo/redo.
Installation Include joint.dia.command.js to your HTML:
<script src="joint.dia.command.js"></script>
Creating CommandManager
var graph = new joint.dia.Graph;
var paper = new joint.dia.Paper({ el: $('#paper'), width: 500, height: 500, model: graph });
var commandManager = new joint.dia.CommandManager({ graph: graph });
$('#undo-button').click(function() { commandManager.undo(); });
$('#redo-button').click(function() { commandManager.redo(); });
(source : http://resources.jointjs.com/docs/rappid/v2.1/dia.html)
I'm trying to accomplish two things:
Left Column: Steps are faded by default, but individual steps fade in to full color on hover.
Right Column: A different image is displayed based on the step being hovered in the left column. By default, the first image should be displayed.
I am using the fadeIn function, but I cant get it to work the way I'm hoping. Whats the best way to go about doing this?
Jsfiddle Example
$(document).ready(function() {
$('#step-one')
.hover(
function() {
$('#step-one-image-holder').fadeIn('slow');
}, function() {
$('#step-one-image-holder').fadeOut('fast');
}
);
$('#step-two')
.hover(
function() {
$('#step-two-image-holder').fadeIn('slow');
}, function() {
$('#step-two-image-holder').fadeOut('fast');
}
);
$('#step-three')
.hover(
function() {
$('#step-three-image-holder').fadeIn('slow');
}, function() {
$('#step-three-image-holder').fadeOut('fast');
}
);
});
If you use "hover" the images will disappear always when you leave the left column (I not sure if you want it). You may use "fadeIn" and "fadeOut" inside a "mouseenter" event:
(Maybe you need to put the images on absolute position to avoid the flickering)
//---Show images on mouseenter
$("div[id^='step-']").on("mouseenter", function(){
var image = $("img[id='" + $(this).attr("id") + "-image-holder']");
$("img[id^='step-']").not(image).fadeOut();
image.fadeIn();
});
//---Hide images by default
$("img[id^='step-']:gt(0)").hide();

Scratching my head on this one.
We have a list of text on the left side of the page. Each item in the list has a data-id attribute that makes it easy to match up corresponding schools in our SVG map. This SVG map is a map of the US, and has school locations fed in from a CSV excel sheet and stored in "schools" for access.
circles.selectAll("circles")
.data(schools)
.enter().append("svg:a")
.attr("xlink:href", function(d) { return d.url; })
.append("svg:circle")
.attr("school", function(d, i) { return d.name; })
.attr("id", function(d, i) { return d.id; })
.attr("cx", function(d,i) { return d.longitude; })
.attr("cy", function(d,i) { return d.latitude; })
.attr("r", function(d,i) { return 6; })
.attr("i", function(d,i) { return i; })
.attr("class", "icon")
So when a user hovers over this list of text I previously mentioned, I use this function:
mapSearch = function(id) {
d3.selectAll("circle")
.filter(function(d) {
if (d.id == id) {
return show_bubble_2(d);
}
})
}
Which calls:
show_bubble_2 = function(school_data) {
var school_info = school_data,
latitude = school_info.latitude,
longitude = school_info.longitude;
bubble.css({
"left": (longitude - 75)+"px",
"top": (latitude - 67)+"px"
});
bubble.html("<h1>" + school_info.name + "</h1>" + "<p>" + school_info.city + ", " + school_info.state + "</p>")
.attr("class", function(d) { return school_info.letter; });
bubble.addClass("active");
}
This works unless we start resizing the map to fit different screen sizes, or unless we do special zoom functions on the map. Then the bubbles closer to the west coast are where they're supposed to be but the ones on the east coast are way off. In short, it's a complete nightmare and not at all scalable.
My question: How do I just append this DIV to the corresponding circle ID instead of using an absolute positioned DIV so that no matter what size the map is, the bubble will always pop up right on top of that circle.
I have tried appending inside the if (d.id == id) { } but it always returns errors and so far I haven't figured it out. I'll keep trying something along those lines because I feel like that's the way to do it. If you have a better solution or could point me in the right direction, I would really appreciate it.
Thanks, and have a good one!
You can find the position of the circle even if there is a transform applied by using Element.getBoundingClientRect.
You could use your filtered selection, get the .node() and find its bounding rect. Then by adjusting for the scroll position, you can find the values of top and left to give to your bubble.
This means that the position of the bubble is based on the actual position at which the circle appears on the page, rather than being based on its data, which would require you to take the transforms into account. Try something like this:
mapSearch = function(id) {
// get the selection for the single element that matches id
var c = d3.selectAll("circle")
.filter(function(d) {
if (d.id == id) {
return show_bubble_2(d);
}
});
// get the bounding rect for that selection's node (the actual circle element)
var bcr = c.node().getBoundingClientRect();
// calculate the top/left based on bcr and scroll position
var bubbleTop = bcr.top + document.body.scrollTop + 'px',
bubbleLeft = bcr.left + document.body.scrollLeft + 'px';
// set the top and left positions
bubble.css({
'top': bubbleTop,
'left': bubbleLeft
});
}
Of course, if you are zooming or panning and want the bubble to remain on the circle, you will need to recalculate these values inside your zoom and pan functions, but the process would be the same.
HERE is a demo using circles that are randomly placed within a g element that has a translation and scale applied. Click on an item in the list to place the bubble on the corresponding circle.
A <div> is HTML. A <circle> is SVG. You can't (easily) put HTML elements inside SVG. You'd have to use <foreignobject> elements to do that. (See this question for details.) Alternatively, you could use native SVG elements such as <tspan> instead of <div>
I was wandering if there is a way to adjust width of the math mathjax renders. Some math expression I have are longer and won't fit in a box I have created. Is there a way to squeeze it and make it fit maybe by changing the size or width? I have tried using line breaks but that isn't what I want. An example would be a mathjax like this:
2x+3+4 - /intcos(x) dx
234567897+sin(2x)+34567890987654.
Displaying the last line would be a problem because it won't fit in the box. It overflows
Well, you could use \small or \scriptsize or \Tiny (non-standard) or \tiny within the mathematics to make it appear in a smaller size.
Alternatively, you could put a <span style="font-size:70%">...</span> around the mathematics to get the math to be scaled to whatever size you need. E.g.,
<span style="font-size:70%">\(234567897+sin(2x)+34567890987654\)</span>
Note that the math delimiters must be inside the <span>.
I found a solution that doesn't require adding elements or css code:
// resize all LaTeX Display elements to they fit in on screen
function cvonk_ResizeMathJax() {
jQuery('.MathJax_Display').each(function(ii, obj) {
var latex = obj.children[0];
var w = latex.offsetWidth;
var h = latex.offsetHeight;
var W = obj.offsetWidth;
if (w > W) {
obj.style.fontSize = 95 * W / w + "%";
}
});
}
window.MathJax = {
AuthorInit: function() {
MathJax.Hub.Register.StartupHook("Begin", function() {
MathJax.Hub.Queue(function() {
cvonk_ResizeMathJax();
});
});
},
jax: ["input/TeX", "output/HTML-CSS", "output/NativeMML"],
extensions: ["tex2jax.js"]
};
window.addEventListener("resize", function() {
cvonk_ResizeMathJax();
});
From the Google Groups discussion linked to above:
function changeSize(button) {
var myeqn = document.getElementById('myeqn');
myeqn.style.fontSize = button.textContent;
MathJax.Hub.Queue(
['Rerender', MathJax.Hub, 'myeqn'],
function () {
document.getElementById('mylabel').innerHTML =
'width: ' + myeqn.offsetWidth + ", height: " + myeqn.offsetHeight;
});
}
See http://jsfiddle.net/nLyraL1f/ or http://jsfiddle.net/s2bjepk6/.
This is also nice because it gets the width and height of the rendered latex, useful for things like rendering it as an element positioned over a canvas since you can draw things on the canvas around it.
I had tried looking up on here many different answers to this question and tried using their solutions, but it didn't seem to work, such as this solution:
Is it possible to hide href title?
My question is how am I able to hide the title attribute tooltip when the user mouses over the picture? I tried using the <span title=" ">text</span> but it only caused the title tooltip to show the space or the span's title attribute.
Here is my website.
I figured out the answer to my question. Thank you Gert G for getting me started! =]
What I did in order to hide the title attribute, was first to put everything into a loop because otherwise, it will take the first link's title and apply it to the picture clicked on:
$("a[rel='portfolio']").each(function(e) {
}
Then, I declared a variable that contains the title to whatever elements you want them applied to:
var title = $(this).attr("title");
Once I declared the variable, I then created a function that hides the title when it's moused over, then adds the title back on when I mouseout on it (for the purpose of having my lightbox, ColorBox).
$(this).mouseover(
function() {
$(this).attr('title','');
}).mouseout(
function() {
$(this).attr('title', title);
});
In order for the title to be viewed when click on, you have to add another function:
$(this).click(
function() {
$(this).attr('title', title);
}
);
Putting it all together, it looks like this:
$("a[rel='portfolio']").each(function(e) {
var title = $(this).attr('title');
$(this).mouseover(
function() {
$(this).attr('title','');
}).mouseout(
function() {
$(this).attr('title', title);
});
$(this).click(
function() {
$(this).attr('title', title);
}
);
});
I hope this helps everyone else looking for a similar or this exact solution!
You can check out the changes here.
Thanks Abriel for the solution, I have converted it to YUI 3 and below is the code in case anyone needed it
YUI().use('node', function(Y) {
Y.all("a[rel='portfolio']").each(function(node) {
var title = node.get('title');
node.on('mouseover', function(ev) {
ev.target.set('title', ev.target.get('text'));
ev.target.on('mouseout', function(e) {
e.target.set('title', title);
})
})
node.on('click', function(ev) {
ev.target.set('title', title);
})
})
})
I was looking for a jquery solution but I am using a javascript solution that works fine for me. I needed the "title" attribute to pass descriptive information about a product / image and within that descriptive information there was basic html tags that were needed. And so whenever someone passed the mouse over the image this mixed code and description will popup. This was less than desirable so I am using the following code so that the "title" information is hidden during mouseover but the title information is still available onclick.
Add this in your link code! Hope this helps someone:
onclick=\"javascript: this.title='description and or html goes here' ;\"
onMouseOver=\"javascript: this.title='' ;
Cheers!
Its works like this:
1:Create your own attribute and call it from lightbox
click me
2:Rename the title attribute in jquery file to:
getAttribute('stitle')
I used it for my tooltip, but it should work even without it.
I nested my link and putted title inside it. Than into nested image I´ve wrote title=" " (with that space).
<a href="http://myweb.com" class="tooltip" id="facebook" title="Sing up to my Newsletter"
<img title=" " src="../img/email.png" alt="email icon" width="32">
</a>
Than, when I hover on my email icon, no title is shown.
