Ways to dynamically manipulate HTML elements in Angular 5

Recently, I've been attempting to programmatically transform an HTML element. Strangely, when I update the transform value in the console tab, it changes successfully, but for some reason it doesn't reflect in the element tab of the browser.

onDragStart(element: HTMLElement) {
    this.elementRef = element;
    var style = window.getComputedStyle(element);
    var matrix = new WebKitCSSMatrix(style.webkitTransform);
    this.translateY = matrix.m42;
    console.log(this.translateY) //outputs: 85, because its current Y-location is 85px 

    element.style.transform = "translate( 0px," + this.translateY + "px)";
    console.log(element);    
  }

I've been troubleshooting this issue for the past 24 hours, but I can't seem to figure out where I'm going wrong. Any guidance would be greatly appreciated.

Answer №1

Indeed, the question was correct both syntactically and logically.

I realized that the top attribute of the html-element had not been set, causing it to behave non-ideally (moving to location translation(0px,0px) from its current position) on the first click.

It is important to first set the top attribute before applying the transform, as setting top helps maintain its original position before translating it to another location.
