• 一些常见的问题与解决代码！(精典) 4

     单击表格中某个单元格则这个单元格变颜色
    <script language="JavaScript">
    function test(t) {
        for (var i=0; i<t.rows.length; i++)
        for (var j=0; j<t.rows[i].cells.length; j++)
        t.rows[i].cells[j].bgColor = t.rows[i].cells[j] == event.srcElement ? 'red' : '';
    }
    </script>
    <table width="300" cellspacing="1" bgcolor="black" onClick="test(this)">
    <tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>
    <tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>
    <tr bgcolor="white" height="20"><td> </td><td> </td><td> </td></tr>
    </table>


    单选框问题

    有三个单选框，
    <input type=radio name=1>222
    <input type=radio name=2>222
    <input type=radio name=3>222
    怎么样使选中第一个后才能选择下面两个中的一个。

    <script>
    function change(radobj){
    var obj = document.getElementsByName("radio2");
    for(i=0;i<obj.length;i++){
       obj[i].disabled = !radobj.checked;
    }
    }
    </script>
    <input type=radio name="radio1" onclick=change(this)>222
    <input type=radio name="radio2" disabled>222
    <input type=radio name="radio2" disabled>222



    鼠标划过，表格变色
    <table cellpadding="0" cellspacing="0" width="100%">
    <tr onmouseover="this.bgColor='red'" onmouseout="this.bgColor=''">
    <td>This is only an Example</td><td>This is only an Example</td>
    </tr></table>


    tbody区域滚动条

     背景不停变化

    脚本说明:
    第一步:把如下代码加入<body>区域中
    <SCRIPT language=javascript><!--
    var pos=10;function initArray(){this.length=initArray.arguments.length;
    for(var i=0;i<this.length;i++){this[i]=initArray.arguments[i];}}
    var col=new initArray("4b","5b","8b","8b");
    col[0]="yellow";col[1]="coral";col[2]="orange";col[3]="red";
    col[4]="greenyellow";col[5]="lime";col[6]="turquoise";col[7]="coral";
    col[8]="blueviolet";col[9]="violet";
    function chgCol(){pos++;if(pos<0||pos>9){pos=0;}document.bgColor=col[pos];
    setTimeout("chgCol()",3000);/*这里你可以改变时间间隔.*/
    }
    var yourwords="不断变化背景色彩";var buffer1=" ";
    var buffer2=" ";
    var message1=buffer1+yourwords+buffer2;
    var dir="left";var speed=150;function pingpong(){
    if(dir=="left")
    {message2=message1.substring(2,message1.length)+" ";
    window.status=message2;setTimeout("pingpong();",speed);message1=message2;
    if(message1.substring(0,1)=="*")dir="right";}
    else{message2=" "+message1.substring(0,message1.length-2);
    window.status=message2;setTimeout("pingpong();",speed);
    message1=message2;if(message1.substring(message1.length-1,message1.length)=="*")dir="left";}}//
    -->
    </SCRIPT>


    第二步:把<body>改为
    <body bgColor=#ffffff onload="chgCol(); pingpong();">
