मैं जेएस और डी 3 के लिए नया हूं। मैंने एक प्रकार का हीटमैप बनाया है और डी 3 के ऑन.माउसओवर का उपयोग करके टाइल का रंग बदलना चाहता हूं। मैं रंग को स्पष्ट रूप से बदलने में सक्षम हूं लेकिन एक सीएसएस सक्रिय नियम का उपयोग करना चाहता हूं। शायद ठीक करने के लिए कुछ आसान है। किसी भी तरह की सहायता का स्वागत किया जाएगा। पूरा कोड नीचे है।वर्गीकृत ("सक्रिय", सत्य) का उपयोग करके माउसओवर पर डी 3 रंग परिवर्तन
धन्यवाद।

मदद के लिए धन्यवाद। यह मेरे अंत में या तो काम नहीं करता था। मैं सोच रहा हूं कि मेरे सीएसएस नियम में कोई नौसिखिया गलती है या मैं इसका संदर्भ कैसे देता हूं। – glynnsc
