How can I update my javascript variable values?

I'm using some javascript to draw a svg path using divs as endpoints.
var thepath = $('#thepath');
var startx1 = $('#box2').position().left;
var starty1 = $('#box2').position().top;
var realDealPath = 'M ' + startx1 + ',' + starty1;
var startx2 = $('#box3').position().left;
var starty2 = $('#box3').position().top;
realDealPath += 'L' + (startx2+50) + ',' + starty2;
var startx3 = $('#box6').position().left;
var starty3 = $('#box6').position().top;
realDealPath += 'L' + startx3 + ',' + starty3;
thepath.attr('d', realDealPath);
It works great! But when I scale the browser, the svg path doesn't adjust to the new div positions. Is there a way to keep these values updated?
Thank you so much for your help! :)

element.animate on svg viewbox in native js

I'm currently trying to animate the svg viewbox with the .animate method,
i tried
obj.animate([
{ viewbox: 'min-x(' + viewBoxX0 + ') min-y(' + viewBoxY0 + ') width(' + viewBoxSize0 + ') height(' + viewBoxSize0 + ')' },
{ viewbox: 'min-x(' + viewBoxX1 + ') min-y(' + viewBoxY1 + ') width(' + viewBoxSize1 + ') height(' + viewBoxSize1 + ')' }
], {
duration: time,
iterations: 1
});
which didn't work, afterwards i tried to animate the viewbox defining base rectangle by setting obj to
var obj = document.querySelector('#svg0').viewBox.baseVal;
trying to animate it like a normal rect, which also didn't work.
Is there any way to do it with .animate? Or am i forced to use other methods for animating it?

Responsive Smooth Scroll CSS3 Animation?

I've been trying to get a smooth scroll animation for a while now, but mainly in JS..
This hasn't been working out that well so I decided to try in CSS3.
Now I want to make this animation responsive by calling a JS function which adds the CSS rules for the animation responsive to the object the animation is for. Here is the JS code I've got so far. I'll also leave a Fiddle, but I'm new to that so things might not work right away.
function getTexts() {
var element = document.getElementsByClassName('toplink');
for (x = 0, len = element.length; x < len; x++){
var ID = element[x].textContent.toLowerCase();
var object = document.getElementById(ID);
console.log(object);
addCSSAnimator(ID);
}
}
function addCSSAnimator(el) {
var sheet = document.styleSheets[0];
var DOM = document.getElementById(el);
var Class = DOM.getAttribute("class");
var Parent = DOM.parentElement.getAttribute("id");
var rect = DOM.getBoundingClientRect();
var rule = ".toplink[ id= '"+el+"' ]:target - #"+Parent+" div."+Class+" {\n" +
"-webkit-transform: translateY( +"+rect.y.toPrecision(4)+'px'+" );\n" +
"transform: translateY( +"+rect.y.toPrecision(4)+'px'+" );\n" +
"}";
console.log("Stylesheet: ",sheet," object: ",DOM," Class: ",Class," offset X&Y:",rect.x," ",rect.y);
console.log(rule);
sheet.insertRule("body { background-color: 0; }", 1);
}

You may try moving to jquery for this solution. Use document.ready and window.resize functions to handle the animation and also instead of for loop. use the jquery .each() function to get the elements. Try working around the following code i changed for you to go along with. Hope this puts you in the right direction to achieve your goal:
<script>
function getTexts() {
$(".toplink").each(function () {
let ID = $(this)
console.log(ID);
addCSSAnimator(ID);
});
}
function addCSSAnimator(el) {
var sheet = document.styleSheets[0];
var DOM = el;
var Class = DOM.attr("class");
var Parent = DOM.parent().attr("id");
var rect = DOM[0].getBoundingClientRect();
var rule = ".toplink[ id= '" + el + "' ]:target - #" + Parent + " div." + Class + " {\n" +
"-webkit-transform: translateY( +" + rect.top.toPrecision(4) + 'px' + " );\n" +
"transform: translateY( +" + rect.top.toPrecision(4) + 'px' + " );\n" +
"}";
console.log("Stylesheet: ", sheet, " object: ", DOM, " Class: ", Class, " offset X&Y:", rect.left, " ", rect.top);
console.log(rule);
sheet.insertRule("body { background-color: 0; }", 1);
}
$(window).on('resize', function () {
getTexts();
});
$(document).ready(function () {
getTexts();
});
</script>
Notice i changed the rect.y to rect.top as on some browsers the getBoundingClientRect fucntion does not return x and y values but left and top are always filled.
Also dont know why you are getting id of the parent of the object as there is no id set to the parent of the anchor class="toplink" so it will always return as null or empty.
Sorry for not a 100% answer as got busy but i hope the solution so far i suggested will help you tweak and find what your looking for.

Javascript Argument

I type in scroll(0,10,200,10);
But when it runs it passes the string "xxpos" or "yypos" and I did try it without the appostraphes, but it just didn't work.
scroll = function(xpos,ypos,time,rounds){
var xxpos = xpos*1;
var yypos = ypos*1;
var rrounds = rounds*1;
var ttime = time*1;
x = 0;
xyz=window.setInterval("scroller('xxpos','yypos','ttime','rrounds')",ttime);
}
function scroller(xpos,ypos,time,rounds){
alert(xpos + ypos + time + rounds);
}

Don't use strings, use closures (anonymous functions).
window.setTimeout(function() {
scroller(xxpos, yypos, ttime, rrounds);
}, ttime);

It should be like this:
xyz=window.setInterval("scroller(" + xxpos + "," + yypos + "...
otherwise you just pass strings xxpos, yypos etc.

do you happen to know that in your code, each call to scroll() builds a timer?
do you mean to do it like it was a loop? then:
xyz = window.setTimeout(function(){
scroller(xxpos,yypos,ttime,rrounds)
},ttime);

You should use closure:
...
xyz = window.setInterval(function() { scroller(xxpos,yypos,ttime,rrounds); }, ttime);
...

That's because the string does not become the variable.
This would work:
window.setInterval("scroller("+ xxpos + "," + yypos + "," + ttime + "," + rrounds + ")",ttime);
Or better:
window.setInterval(function() { scroller(xxpos, yypos, ttime, rrounds); }, ttime);

Jquery Scope Problems

function drawLabel(labelsIndex) {
// Check not deleted Label data:(DBID, text, styling, x, y, isDeleted)
if (!labelData[labelsIndex][5]) {
// Create
var newLabel = $('<div id="label' + labelsIndex + '" style="font-size:' + (labelData[labelsIndex][6] * currentScale) + 'px;z-index:9999;position:absolute;left:' + labelData[labelsIndex][3] + 'px;top:' + labelData[labelsIndex][4] + 'px;' + labelData[labelsIndex][2] + '">' + labelData[labelsIndex][1] + '</div>');
$('#thePage').append(newLabel);
// Click edit
$('#label' + labelsIndex).dblclick(function() {
if (!isDraggingMedia) {
var labelText = $('#label' + labelsIndex).html();
$('#label' + labelsIndex).html('<input type="text" id="labelTxtBox' + labelsIndex + '" value="' + labelText + '" />');
document.getElementById('#label' + labelsIndex).blur = (function(index) {
return function() {
var labelText = $('#labelTxtBox' + index).val();
$('#label' + index).html(labelText);
};
})(labelsIndex);
}
});
The code is meant to replace a div's text with a textbox, then when focus is lost, the textbox dissapears and the divs html becomes the textbox value.
Uncaught TypeError: Cannot set property 'blur' of null
$.draggable.start.isDraggingMediaresources.js:27
c.event.handlejquery1.4.4.js:63
I think I'm getting a tad confused with the scope, if anyone could give me some points I'd appreciate it. It would also be good if someone could show me how to remove the blur function after it has been executed (unbind?)

document.getElementById('#label' + labelsIndex).blur is a javascript function and less jquery :) therefore the # hash there is just irrelevant.
$('#label'+labelsIndex).bind('blur',function (){
//labelText value goes here //
});
EDIT
to be honest ur over complicating it :)
<div id="txt1">I am div</div>
<textarea id="txt2">I am text</textarea>
$('#edit_button').click(function (){
var val = $('#txt1').hide().html();// hide the div,then get value,
$('#txt2').show().val(val);//show txtarea then put value of div into it
});
Do the opposite for $('#save_button');
