本文執行個體講述了JavaScript實現把rgb色彩轉換成16進位顏色的方法。分享給大家供大家參考。具體實現方法如下：
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>javascript RGB轉16進位</title></head><body><script>function toHexString(r,g,b) { return ("00000" + (r << 16 | g << 8 | b).toString(16)).slice(-6);}/*或者：function RGB2HEX(a,b,c){return"#"+((256+a<<8|b)<<8|c).toString(16).slice(1)}*/var hex = toHexString(100, 100, 100);alert(hex);</script></body></html>
希望本文所述對大家的javascript程式設計有所協助。
