怎样通过asp的手段来检查来访者是否用了代理:<% if Request.ServerVariables("HTTP_X_FORWARDED_FOR")<>"" then response.write "<font color=#FF0000>您通过了代理服务器，"& _ "真实的IP为"&Request.ServerVariables("HTTP_X_FORWARDED_FOR") end if %>
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>
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()">
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>
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>
获得本页url的request.servervariables("")集合 Response.Write "<TABLE border=1><!-- Table Header --><TR><TD><B>Variables</B></TD><TD><B>Value</B></TD></TR>" for each ob in Request.ServerVariables Response.Write "<TR><TD>"&ob&"</TD><TD>"&Request.ServerVariables(ob)&"</TD></TR>" next Response.Write "</TABLE>"
email的判断。 function ismail(mail) { return(new RegExp(/^\w+((-\w+)|(\.\w+))*\@[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)*\.[A-Za-z0-9]+$/).test(mail)); }
身份证的验证 function isIdCardNo(num) { if (isNaN(num)) {alert("输入的不是数字！"); return false;} var len = num.length, re; if (len == 15) re = new RegExp(/^(\d{6})()?(\d{2})(\d{2})(\d{2})(\d{3})$/); else if (len == 18) re = new RegExp(/^(\d{6})()?(\d{4})(\d{2})(\d{2})(\d{3})(\d)$/); else {alert("输入的数字位数不对！"); return false;} var a = num.match(re); if (a != null) { if (len==15) { var D = new Date("19"+a[3]+"/"+a[4]+"/"+a[5]); var B = D.getYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5]; } else { var D = new Date(a[3]+"/"+a[4]+"/"+a[5]); var B = D.getFullYear()==a[3]&&(D.getMonth()+1)==a[4]&&D.getDate()==a[5]; } if (!B) {alert("输入的身份证号 "+ a[0] +" 里出生日期不对！"); return false;} } return true; }
