2.有两个按钮 点击隐藏 input输入框就隐藏 显示input就显示
<input type="button" value="隐藏" onclick="csan(did,'none')"> <input type="button" value="显示" onclick="csan(did,'')"> <input id="did"> <br> <input type="button" value="隐藏" onclick="csan(dis,'none')"> <input type="button" value="显示" onclick="csan(dis,'')"> <input id="dis"> <script> function csan(obj,sta){ eval("obj.style.display=""+sta+"""); } </script>
3.input框中信息的滚动显示
<SCRIPT LANGUAGE="JavaScript">var myMainMessage=" 我是滚动文字 我是滚动文字 我是滚动文字 滚滚滚——————"; var speed=150; var scrollingRegion=50; var startPosition=0; function mainTextScroller() { var mainMessage=myMainMessage; var tempLoc=(scrollingRegion*3/mainMessage.length)+1; if (tempLoc<1) {tempLoc=1} var counter; for(counter=0;counter<=tempLoc;counter++) mainMessage+=mainMessage; document.mainForm.mainTextScroller.value=mainMessage.substring(startPosition,startPosition+scrollingRegion); startPosition++; if(startPosition>scrollingRegion) startPosition=0; setTimeout("mainTextScroller()",speed); } </script> <body bgcolor="#ffffff" onLoad="mainTextScroller()"> <form name="mainForm"> <center> <input type="text" name="mainTextScroller" size="40" value> </center> </form> </body>
