get the CSS maxWidth value of the parent javascript


get the CSS maxWidth value of the parent javascript

To fix this issue You were on the right track - so, your first approach does not work in this case because the element doesn't have max-width directly inside its style declaration (see sample below with .other for when this would work).
The second approach is correct, but you mixed up access argument a little - if you use .getPropertyValue, you use CSS-style "max-width", and if you don't, you use .maxWidth like with .style:
code :
var childDIV=document.querySelector('.child');

var result= document.querySelector('.other').style.maxWidth;
console.log(`Approach 1: ${result}`);

var compStyle = window.getComputedStyle(childDIV.parentNode,null);

result = compStyle.maxWidth;
console.log(`Approach 2: ${result}`);

result = compStyle.getPropertyValue("max-width");
console.log(`Approach 3: ${result}`);
.parent{max-width:100px}
<div class="parent"><div class="child"></div></div>

<div class="other" style="max-width:50px"></div>

I hope this helps . You can emulate maxWidth and maxHeight in IE6 using CSS expressions - example here http://www.cameronmoll.com/archives/000892.html. Make sure you conditionally apply these rules to target only IE6 and keep in mind that CSS expressions have some big performance issues.

This might help you offsetHeight and offsetWidth will get you what you want, and take into account the maxWidth and maxHeight. Do keep in mind that the img object needs to be part of the DOM to have any dimensions at all. So you'll need to add it with something like document.body.appendChild($new_image) before offsetHeight and width will return anything useful.

this one helps. For me: in IE9, Opera, Safari(PC), FF and chrome the naturalWidth/naturalHeight-properties return the desired values

Hope that helps Looks like you want to add a children key with an array of values to the objects in your initial array where the id value corresponds to one or more parentCategoryId values from other objects in the array - and no object should be repeated as a parent or child in the array of nested objects.
You could map the array to append children, and then filter to return just the root parents (and orphans). For example (working snippet below the example if you want to see the output):
code :
const ids = table.map(x => x.id);

let result = table.map((parent) => {
  let children = table.filter((child) => {
    if (child.id !== child.parentCategoryId && child.parentCategoryId === parent.id) {
      return child;
    }
  });
  if (children.length) {
    parent.children = children;
  }
  return parent;
}).filter((obj) => {
  if (obj.id === obj.parentCategoryId || !ids.includes(obj.parentCategoryId)) {
    // include ultimate parents and orphans at root
    return obj;
  }
});
const table = [{
    "id": 791,
    "sortOrder": 0,
    "parentCategoryId": 833
  },
  {
    "id": 790,
    "sortOrder": 0,
    "parentCategoryId": 833
