</html>
Basically I want the rotation of the container div to vary accordingly to the var vento_direzione (which it is a number obtained from the api request to witch I have appended a "deg" string) whenever I click the button; sadly, that doesn't seem to happen. If I just pass a value inside the function instead of the var, everything works fine. What am I doing wrong?
Please help! Cheers!


you want
document.getElementById("container").style.webkitTransform = "rotate("+vento_direzione+")";
As it is you are just trying to pass it the literal string "rotate(vento_direzione)", variables do not get replaced with their values when they are in strings like that.
So what you need to do is concatenate the actual string parts "rotate(" and ")" with the vento_direzione variable: "rotate("+vento_direzione+")" is string concatenation

Click svg path and change option value on a select component

Currently I have some code that when selecting a value from a dropdown list will paint a specific path of a svg image.
var paths1 = {
"https://www.google.com": {
color: "#eb8c00",
selector: "#path1"
},
"https://www.yahoo.com": {
color: "#eb8c00",
selector: "#path2"
},
}
$('#path').on("change", function() {
$('#path1, #path2').css({
fill: "#FFFFFF"
});
var value = $(this).val()
if (!value) {
return;
}
var {
color,
selector
} = paths1[value]
$(selector).css({
fill: color
});
});

</select>
<div>
<input

class="selectbutton"

onClick="window.open(path.value,'newtab'+path.value)">
</div>
It works fine, as the button will also redirect to a different page.Now I need to be able to the reverse. I want to click on a path and the dropdown selector will also change. Clicking on path1 will select Google and clicking on path2 will select Yahoo from my dropdown list.
How can I achieve this?

To achieve this, you could define a click event handler:
$('#Layer_1 path').on("click", function() {...});
and use a for in loop to compare the selector values in the paths1 array with the ID of the clicked path:
for (key in paths1) {
if (paths1[key].selector == '#' + this.id) {...}
}
If you found a match, you can use the key to select the option tag and assign the selected property to it:
$('option[value="' + key + '"]').prop('selected', true);
All together:
$('#Layer_1 path').on("click", function() {
for (key in paths1) {
if (paths1[key].selector == '#' + this.id) {
$('option[value="' + key + '"]').prop('selected', true);
}
}
});
You could also change the colors similar to the other event handler:
$('#Layer_1 path').on("click", function() {
for (key in paths1) {
if (paths1[key].selector == '#' + this.id) {
$('option[value="' + key + '"]').prop('selected', true);
$('#path1, #path2').css({
fill: "#FFFFFF"
});
$(this).css({fill: paths1[key].color});
}
}
});
Working example:
var paths1 = {
"https://www.google.com": {
color: "#eb8c00",
selector: "#path1"
},
"https://www.yahoo.com": {
color: "#eb8c00",
selector: "#path2"
},
}
$('#path').on("change", function() {
$('#path1, #path2').css({
fill: "#FFFFFF"
});
var value = $(this).val()
if (!value) {
return;
}
var {
color,
selector
} = paths1[value]
$(selector).css({
fill: color
});
});
$('#Layer_1 path').on("click", function() {
for (key in paths1) {
if (paths1[key].selector == '#' + this.id) {
$('option[value="' + key + '"]').prop('selected', true);
$('#path1, #path2').css({
fill: "#FFFFFF"
});
$(this).css({fill: paths1[key].color});
}
}
});

here is a code that you can check out as an example. It must help. Good luck.
function SelectADropdownItem(id, val) {
var d = document.getElementById(id);
for (var i = 0; i < d.length; i++) {
if (d[i].value == val) {
d[i].selected = true;
} else {
d[i].selected = false;
}
}

Mousemove and Hover Jquery effect to Pure Javascript or VueJS event

I have a VueJS component which is a svg map image of the united states. I previously used jquery to create hover effects to display the information bubble. I am trying to convert this to a pure Javascript solution. It seems a click event is the easiest to implement given vuejs mousemove seems to be less reliable. I have added the click event in method and I am trying to capture the SVG path location and steal the top and left position to enable the info box there. I have tried this.offsettop and this.offsetleft but they return undefined.
Jquery code I am trying to convert:
$("path, circle").hover(function(e) {
$('#info-box').css('display','block');
$('#info-box').html($(this).data('info'));
});
$("path, circle").mouseleave(function(e) {
$('#info-box').css('display','none');
});
$(document).mousemove(function(e) {
$('#info-box').css('top',e.pageY-$('#info-box').height()-30);
$('#info-box').css('left',e.pageX-($('#info-box').width())/2);
}).mouseover();
var ios = /iPad|iPhone|iPod/.test(navigator.userAgent) && !window.MSStream;
if(ios) {
$('a').on('click touchend', function() {
var link = $(this).attr('href');
window.open(link,'_blank');
return false;
});
}

The solution was found in the comments on the question.
In summary, the issue was understanding how to position the #info-box element. Using the getBoundingClientRect() function, we can get the position of any element relative to the entire document. To get the position of the clicked path element, simply subtract the top and left of the #us-map from the top and left of the path. This will give the position for the top left corner of the path, relative to the containing element. We can then use that to position the #info-box.

How can i move SVG Polygon element by mouse?

I want to move this polygon by mouse. How can i do this?
I think i should use some like onMouseDown and onMouseMove get new position and transform="translate(x,y) but how can i do this by JS?

You can use draggable from jquery UI. Here is your edited code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<script>
$( function() {
$( "#Layer_1" ).draggable();
} );
</script>
</head>
<body>
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 500 500" style="enable-background:new 0 0 500 500;" xml:space="preserve">
<polygon class="st0" points=" 0,5 10,0 20,5 10,10" transform="translate(90,95) rotate(0 0 0)" stroke="none" fill="red"/>
</svg>
</body>
</html>

Take the reference from below, it's working:
HTML:
<svg id="pointer" height="50" width="50">
<polygon points="1,1 49,10 20,20 10,49">
<!-- coordinates are in x,y format -->
<!-- points go clockwise around the polygon -->
</svg>
bbc
CSS:
#pointer {
overflow: hidden;
position: fixed;
top: 200px;
left: 200px;
position: relative;
}
html {
cursor: none;
}
a {
font-size: 40px;
}
a:hover {
cursor: pointer;
}
Javascript:
var mouseX;
var mouseY;
window.onmousemove = handleMouseMove;
function handleMouseMove(event) {
event = event || window.event;
document.getElementById('pointer').style.top=event.clientY + "px";
document.getElementById('pointer').style.left=event.clientX + "px";
}

Vertically centering part of svg content

I've been trying to center a collection of svg paths/text vertically in CSS / JS for quite a while with no luck. None of the solutions I've found here have worked so far. I have multiple < text > , < circle >, < rect >, although I don't think the type of content really matters.
The height is variable, so I have thought of 2 methods:
1) Transform via 50%. This is not working because you cannot transform a sub-set of content from a svg, from what I have found so far. The < g > tag was promising but I had no luck.
2) My second idea was to adjust the mask down via javascript once content is loaded. This, likewise, is not working.
All code is on code-pen and copied here as well: https://codepen.io/anon/pen/MmdWXB
HTML:
<div class="mask_group" id="mask_container">
<div class="text">
<svg>
<defs>
<mask id="mask" x="0" y="0" width="100%" height="100%" >
<rect class="cutout label" x="0" y="0" width="100%" height="100%"/>
<text class="label normal_font_weight" y="1em" dy="0em" x="50%">A</text>
<text class="label normal_font_weight" y="3em" dy="0em" x="50%">B</text>
<line class="label" x1="47%" y1="4.6em" x2="53%" y2="4.6em" style="stroke:rgb(255,0,0);stroke-width:1.5" />
<text class="label" y="7em" dy="0em" x="50%">C</text>
<text class="label" y="9em" id="final_text" dy="0em" x="50%">D</text>
</mask>
</defs>
<rect id="base" x="0" y="0" width="100%" height="100%"/>
</svg>
</div>

<div style="background-color:blue; width: 100%; height: 100%">

/*top: 0;

/*z-index: 11; */
}
.mask_group {

-webkit-mask: url(#mask);
mask: url(#mask);
}
/*Unused*/
.vert_center {
position: relative;
margin-top: 50%;
transform: translateY(-50%);
}
JS:
function body_loaded() {
var final_text = document.getElementById("final_text");
var position = final_text.getBoundingClientRect();
var bottom = position.bottom;
var mask_container = document.getElementById("mask_container");
var mask_position = mask_container.getBoundingClientRect();
var mask_height = mask_position.height;
var origin_y = (mask_height - bottom) / 2;
alert(origin_y);
var mask = document.getElementById("mask");
mask.style.y = origin_y;
}
Thanks ahead of time!

I'm not sure what you are attempting to do with the <mask>, so I am going to ignore it for now.
To vertically centre the SVG, just give it a fixed height and use the standard translate(-50%) trick. The only wrinkle is that you can't put the CSS transform on the <svg> element because transform has a different behavior in SVGs than it does in CSS. SVG transforms pre-date CSS transforms. So you just need to wrap the SVG in an HTML container and apply the transform to that instead.
I've set the height of the <svg> to 10em. Obviously you'll need to adjust that if you have more text. You could do that with JS using
svgElem.setAttribute("height", "10em");
But take it out of the CSS first obviously :)
html,body {
height: 100%;
}
.svg-wrapper {
position: absolute;
width: 100%;
top: 50%;
transform: translate(0, -50%);
}
.mask_group {
position: fixed;
width: 100%;
height: 100%;
z-index: 10;
}
svg {
width: 100%;
height: 10em;
fill: blue; /* default fill colour for contents */
}
svg text {
text-anchor: middle;
}
svg #base {
fill: #051E2A; /*#1F5773;*/
}
<div class="mask_group" id="mask_container">
<div class="svg-wrapper">
<svg>
<rect id="base" x="0" y="0" width="100%" height="100%"/>
<text class="label normal_font_weight" y="1em" dy="0em" x="50%">A</text>
<text class="label normal_font_weight" y="3em" dy="0em" x="50%">B</text>
<line class="label" x1="47%" y1="4.6em" x2="53%" y2="4.6em" style="stroke:rgb(255,0,0);stroke-width:1.5" />

<text class="label" y="9em" id="final_text" dy="0em" x="50%">D</text>

How to reset the timer of SVG animation when using beginElementAt()?

I use elt.beginElementAt(-5) on SVG animation with dur="10s", it's worked in 5s, normal.
BUT if at the end of an animation (i.e. at 5 seconds after launch elt.beginElementAt(-5) cmd) I want to trigger it again, It doesn't work!
I have to wait for the "truth" duration (10s in this example), to be able to restart the animation. Nothing happens if I try between 5s and 10s after my first elt.beginElementAt(-5) command...
So, how to reset the timer? How to ignore the "normal" duration?
Thanks.

To have SVG start and reset functions work together, set the fill attribute.
