Convert css string to object

Recommended Posts

Hey guys,

 

I have a dynamic template, where you can input css into the XML feed, and the banner will read that on run time and adjust the banner overwrite the styles using set:

 TweenMax.set(element, newValuesObject);

And I've managed to cobble together bits of string replaces and RegEx:

var myDynamicCSS = "color:#ffffff; background-color: #00ffbb; text-align: left; border: 1px solid green";

String.prototype.toCamelCase = function() {
  return this.replace(/^([A-Z])|[\s-](\w)/g, function(match, p1, p2, offset) {
    if (p2) return p2.toUpperCase();
    return p1.toLowerCase();
  });
};

const convertCSS2JS = (css) => {
  let frameCSS = css.replace(/([\w-.]+)\s*[^;]+);?/g, '$1:$2,');
  frameCSS = frameCSS.replace(/,+$/, '');
  let properties = frameCSS.split(', ');
  let frameCSSObj = {};
  properties.forEach(function(property) {
      let cssProp = property.split(':');
      let cssKey = cssProp[0].toCamelCase();
      let cssValue = cssProp[1].trim();
      frameCSSObj[cssKey] = cssValue;
  });
  return frameCSSObj
};

TweenMax.set(myDynamicElement, convertCSS2JS(myDynamicCSS]));

But I'm unsure of how easily breakable this is?

What do you mean by breakable? See if we can come up with combinations of CSS stings to see if this fails?

very nice, handled multiple transforms nicely and they got converted to a matrix by set()

var myDynamicCSS = "color:#ffffff; background-color: #00ffbb; border-radius:20px; transform:translateY(100px) rotate(30deg) scaleX(0.5)";
