系统前端基本文件+ajax部分理解
静态页面:
一、static:
css
dist
fonts
images
js
model
二、templates:
html
ajax搜索操作:
<html> <head> <script type="text/javascript"> function showHint(str) { var xmlhttp; if (str.length==0) { document.getElementById("txtHint").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari//兼容性问题 xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","/ajax/gethint.asp?q="+str,true);//获取asp文件,注意q参数 xmlhttp.send(); } </script> </head> <body> <h3>请在下面的输入框中键入字母(A - Z):</h3> <form action=""> 姓氏:<input type="text" id="txt1" onkeyup="showHint(this.value)" /> </form> <p>建议:<span id="txtHint"></span></p> </body> </html>
下面是asp文件代码
<% response.expires=-1 dim a(30) '用名字来填充数组 a(1)="Anna" a(2)="Brittany" a(3)="Cinderella" a(4)="Diana" a(5)="Eva" a(6)="Fiona" a(7)="Gunda" a(8)="Hege" a(9)="Inga" a(10)="Johanna" a(11)="Kitty" a(12)="Linda" a(13)="Nina" a(14)="Ophelia" a(15)="Petunia" a(16)="Amanda" a(17)="Raquel" a(18)="Cindy" a(19)="Doris" a(20)="Eve" a(21)="Evita" a(22)="Sunniva" a(23)="Tove" a(24)="Unni" a(25)="Violet" a(26)="Liza" a(27)="Elizabeth" a(28)="Ellen" a(29)="Wenche" a(30)="Vicky" '获得来自 URL 的 q 参数 q=ucase(request.querystring("q")) '如果 q 大于 0,则查找数组中的所有提示 if len(q)>0 then hint="" for i=1 to 30 if q=ucase(mid(a(i),1,len(q))) then if hint="" then hint=a(i) else hint=hint & " , " & a(i) end if end if next end if '如果未找到提示,则输出 "no suggestion" '否则输出正确的值 if hint="" then response.write("no suggestion") else response.write(hint) end if %>
也可以用php代码
<?php // 用名字来填充数组 $a[]="Anna"; $a[]="Brittany"; $a[]="Cinderella"; $a[]="Diana"; $a[]="Eva"; $a[]="Fiona"; $a[]="Gunda"; $a[]="Hege"; $a[]="Inga"; $a[]="Johanna"; $a[]="Kitty"; $a[]="Linda"; $a[]="Nina"; $a[]="Ophelia"; $a[]="Petunia"; $a[]="Amanda"; $a[]="Raquel"; $a[]="Cindy"; $a[]="Doris"; $a[]="Eve"; $a[]="Evita"; $a[]="Sunniva"; $a[]="Tove"; $a[]="Unni"; $a[]="Violet"; $a[]="Liza"; $a[]="Elizabeth"; $a[]="Ellen"; $a[]="Wenche"; $a[]="Vicky"; //获得来自 URL 的 q 参数 $q=$_GET["q"]; //如果 q 大于 0,则查找数组中的所有提示 if (strlen($q) > 0) { $hint=""; for($i=0; $i<count($a); $i++) { if (strtolower($q)==strtolower(substr($a[$i],0,strlen($q)))) { if ($hint=="") { $hint=$a[$i]; } else { $hint=$hint." , ".$a[$i]; } } } } // 如果未找到提示,则把输出设置为 "no suggestion" // 否则设置为正确的值 if ($hint == "") { $response="no suggestion"; } else { $response=$hint; } //输出响应 echo $response; ?>
