JavaScript实现彩虹文字效果的方法_javascript技巧_脚

本文实例陈诉了JavaScript完毕彩霓文字效果的主意。分享给大家供大家参谋。具体如下:

Rainbow Text<!-- Begin hide from old browsersfunction createHexArray{ this.length = n; for (var i = 1; i <= n; i  ) this[i] = i - 1; this[11] = "A"; this[12] = "B"; this[13] = "C"; this[14] = "D"; this[15] = "E"; this[16] = "F"; return this;}hx = new createHexArray;function convertToHex x = 16; var high = x / 16; var s = high ""; s = s.substring; high = parseInt; var left = hx[high   1]; var low = x - high * 16; if  low = 1; s = low   ""; s = s.substring; low = parseInt; var right = hx[low   1]; var string = left   ""   right; return string;}function makeRainbow{ text = text.substring; color_d1 = 255; mul = color_d1 / text.length; for(var i = 0; i < text.length; i  ) { color_d1 = 255*Math.sin); color_h1 = convertToHex; color_d2 = mul * i; color_h2 = convertToHex; k = text.length; j = k - i; if  j = 0; color_d3 = mul * j; color_h3 = convertToHex; document.write("<FONT COLOR="#"   color_h3   color_h1   color_h2   "">"   text.substring   "</FONT>"); }}// End hide from old browsers --><!--// change to your own text ...makeRainbow("Welcome to Boulder City Nevada");document.write;makeRainbow("The best dam city in the USA");// -->
