本文實例講述了js實作按鈕色彩漸層動畫效果的方法。分享給大家供大家參考。具體如下:
這裡演示js實現按鈕慢慢變色的方法,滑鼠移到按鈕上,按鈕的背景色就發生變化,是慢慢的變化,點擊按鈕會打開指定鏈接,這裡主要是演示按鈕變色的程式碼實作方法。
運行效果截圖如下:
具體程式碼如下:
<HTML> <HEAD><TITLE>按钮慢慢变色</TITLE> <STYLE type=text/css> BODY { MARGIN-TOP: 0px; FONT-SIZE: 9pt; MARGIN-LEFT: 0px; MARGIN-RIGHT: 0px; FONT-FAMILY: "宋体" } A { FONT-WEIGHT: 400; FONT-SIZE: 9pt; COLOR: black; TEXT-DECORATION: none } A:hover { FONT-WEIGHT: 400; FONT-SIZE: 9pt; COLOR: red; TEXT-DECORATION: underline } A:active { FONT: 9pt "宋体"; CURSOR: hand; COLOR: #ff0033 } .STYLE1 { color: #000099; font-weight: bold; font-family: "华文新魏"; font-size: 30px; } .STYLE2 { color: #FF3399; font-size: 40px; font-family: "华文行楷"; } </STYLE> <META http-equiv=Content-Type content="text/html; charset=gb2312"> </HEAD> <BODY bgColor=#fef4d9> <CENTER> <span class="STYLE2">按钮慢慢变色</span> </CENTER><BR> <CENTER> <TABLE borderColor=#66FF00 border=5 borderlight="green"> <TBODY> <TR> <TD align=middle><span class="STYLE1">效果显示</span></TD> </TR> <TR> <TD align=middle> <SCRIPT language=JavaScript> hexColor = ["0","1","2","3","4","5","6","7","8","9","a","b","c","d","e","f"]; function mOver() { for (i = 0; i < 13; i++) { setTimeout("document.myForm.button.style.background = "#"+hexColor[12-i]+"0"+hexColor[12-i]+"0c0";", i * 40); } } function mOut() { document.myForm.button.value = "进入JavaScript中文网"; for (i = 0; i < 12; i++) { setTimeout("document.myForm.button.style.background = "#"+hexColor[i]+"0"+hexColor[i]+"0c0";", i * 40); } } // End --> </SCRIPT> <FORM name=myForm> <input onMouseDown="document.myForm.button.value=" 谢谢"" onMouseOver=mOver() onClick="window.location="http://www.php.cn/"" onMouseOut=mOut() type=button value=鼠标放在上面 name=button > </FORM> </TD> </TR> </TBODY> </TABLE> </CENTER> </BODY> </HTML>
