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) 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>
