Hello everyone! I am trying to get width and height of the <center> element of the <borderlayout> element for scaling SVG. For this task i am using jQuery and trying to get <div> with CSS class z-center, but it returns null. When i used ZK 6.5.3 it works well, but when i updated to ZK 7.0.0 it stops work.

This is my code:

<n:script xmlns:n="native"><![CDATA[
function autoScale() {
      var width_center = $('$centerLayout .z-center').width();
      var height_center = $('$centerLayout .z-center').height();
      $('svg').attr('width', width_center);
      $('svg').attr('height', height_center);
<center id="centerLayout" autoscroll="true">
  <div id="SVGBox" align="center" vflex="1" style="overflow: auto;">
    <label id="schemeName" value="Object Name" style="font-size: large; display: block;"/>
    <html id="SVGConteiner" vflex="1" />

Why it started return null for variables width_center and height_center? Very interesting thing is that if i write:

var width_center = $('$centerLayout .z-div').width();

it will work fine, and return width of the <div> element with id="SVGBox"


I finded one solution:

var center = $('$centerLayout').find('.z-center');
var width_center = center.width();

But, when i saw in IE console like this

for (var i in center ) {
  console.log(i + ":" + center [i]);

I saw that selector for this object is $centerLayout .z-center. But i can't get that object with this selector. So:

var center = $('$centerLayout .z-center');

is not the same for:

var center = $('$centerLayout').find('.z-center');

Is this a bug, or i doing something wrong?

The center can be matched by another selector $('$centerLayout.z-center'). I will figure it out and give a more detailed explanation in a couple of days. Thanks for your asking!
