JS常用特效方法总结

1.按Ctrl提交

1 <body onkeydown="if(event.ctrlKey&&event.keyCode=='13') form1.submit.click();">
2 
3 <form method=post  action="  " name="form1">
4 <input type="text">
5 <input type="submit" value="发送" name="submit">

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>
