13. 取得控件的绝对位置 //Javascript <script language="Javascript"> function getIE(e){ var t=e.offsetTop; var l=e.offsetLeft; while(e=e.offsetParent){ t+=e.offsetTop; l+=e.offsetLeft; } alert("top="+t+"/nleft="+l); } </script>
//VBScript <script language="VBScript"><!-- function getIE() dim t,l,a,b set a=document.all.img1 t=document.all.img1.offsetTop l=document.all.img1.offsetLeft while a.tagName<>"BODY" set a = a.offsetParent t=t+a.offsetTop l=l+a.offsetLeft wend msgbox "top="&t&chr(13)&"left="&l,64,"得到控件的位置" end function --></script>
14. 光标是停在文本框文字的最后 <script language="javascript"> function cc() { var e = event.srcElement; var r =e.createTextRange(); r.moveStart("character",e.value.length); r.collapse(true); r.select(); } </script> <input type=text name=text1 value="123" onfocus="cc()">
32. 日期减去天数等于第二个日期 <script language=Javascript> function cc(dd,dadd) { //可以加上错误处理 var a = new Date(dd) a = a.valueOf() a = a - dadd * 24 * 60 * 60 * 1000 a = new Date(a) alert(a.getFullYear() + "年" + (a.getMonth() + 1) + "月" + a.getDate() + "日") } cc("12/23/2002",2) </script>
33. 选择了哪一个Radio <HTML><script language="vbscript"> function checkme() for each ob in radio1 if ob.checked then window.alert ob.value next end function </script><BODY> <INPUT name="radio1" type="radio" value="style" checked>Style <INPUT name="radio1" type="radio" value="barcode">Barcode <INPUT type="button" value="check" onclick="checkme()"> </BODY></HTML>
46、自动的为你每次产生最後修改的日期了： <html> <body> This is a simple HTML- page. <br> Last changes: <script language="LiveScript"> <!-- hide script from old browsers document.write(document.lastModified) // end hiding contents --> </script> </body> </html>
<body> <form name="first"> Enter your name:<br> <input type="text" name="text1"> <input type="button" name="button1" value="输 入 测 试" onClick="test1(this.form)"> <P> Enter your e-mail address:<br> <input type="text" name="text2"> <input type="button" name="button2" value="输 入 测 试" onClick="test2(this.form)"> </body>
48、跑马灯 <html> <head> <script language="JavaScript"> <!-- Hide var scrtxt="怎麽样 ! 很酷吧 ! 您也可以试试."+"Here goes your message the visitors to your page will "+"look at for hours in pure fascination..."; var lentxt=scrtxt.length; var width=100; var pos=1-width; function scroll() { pos++; var scroller=""; if (pos==lentxt) { pos=1-width; } if (pos<0) { for (var i=1; i<=Math.abs(pos); i++) { scroller=scroller+" ";} scroller=scroller+scrtxt.substring(0,width-i+1); } else { scroller=scroller+scrtxt.substring(pos,width+pos); } window.status = scroller; setTimeout("scroll()",150); } //--> </script> </head> <body onLoad="scroll();return true;"> 这里可显示您的网页 ! </body> </html>
51、title显示日期 把如下代码加入<body>区域中: <script language="JavaScript1.2"> <!--hide var isnMonth = new Array("1月","2月","3月","4月","5月","6月","7月","8月","9月","10月","11月","12月"); var isnDay = new Array("星期日","星期一","星期二","星期三","星期四","星期五","星期六","星期日"); today = new Date () ; Year=today.getYear(); Date=today.getDate(); if (document.all) document.title="今天是: "+Year+"年"+isnMonth[today.getMonth()]+Date+"日"+isnDay[today.getDay()] //--hide--> </script>
52、显示所有链接 把如下代码加入<body>区域中 <script language="JavaScript1.2"> <!-- function extractlinks(){ var links=document.all.tags("A") var total=links.length var win2=window.open("","","menubar,scrollbars,toolbar") win2.document.write("<font size='2'>一共有"+total+"个连接</font><br>") for (i=0;i<total;i++){ win2.document.write("<font size='2'>"+links[i].outerHTML+"</font><br>") } } //--> </script> <input type="button" onClick="extractlinks()" value="显示所有的连接">
53、回车键换行 把如下代码加入<body>区域中 <script type="text/javascript"> function handleEnter (field, event) { var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode; if (keyCode == 13) { var i; for (i = 0; i < field.form.elements.length; i++) if (field == field.form.elements[i]) break; i = (i + 1) % field.form.elements.length; field.form.elements[i].focus(); return false; } else return true; }
