我正在尝试修改并使用此AJAX live search example来使用PHP从XML文件获取值。
这是工作代码示例:
javascript:
//table//tr/th[text() = 'New']/count(preceding-sibling::th) + 1
html:
function showResult(str) {
if (str.length==0) {
document.getElementById("livesearch").innerHTML="";
document.getElementById("livesearch").style.border="0px";
return;
}
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
xmlhttp.onreadystatechange=function() {
if (this.readyState==4 && this.status==200) {
document.getElementById("livesearch").innerHTML=this.responseText;
document.getElementById("livesearch").style.border="1px solid #A5ACB2";
}
}
xmlhttp.open("GET","livesearch.php?q="+str,true);
xmlhttp.send();
}
php(livesearch.php):
<form>
<input type="text" size="30" onkeyup="showResult(this.value)">
<div id="livesearch"></div>
</form>
所以,我试图从XML文件中获取结果,该XML文件具有与示例不同的结构,并且看起来更加苗条:
xml(links.xml):
$xmlDoc=new DOMDocument();
$xmlDoc->load("links.xml");
$x=$xmlDoc->getElementsByTagName('link');
//get the q parameter from URL
$q=$_GET["q"];
//lookup all links from the xml file if length of q>0
if (strlen($q)>0) {
$hint="";
for($i=0; $i<($x->length); $i++) {
$y=$x->item($i)->getElementsByTagName('title');
$z=$x->item($i)->getElementsByTagName('url');
if ($y->item(0)->nodeType==1) {
//find a link matching the search text
if (stristr($y->item(0)->childNodes->item(0)->nodeValue,$q)) {
if ($hint=="") {
$hint="<a href='" .
$z->item(0)->childNodes->item(0)->nodeValue .
"' target='_blank'>" .
$y->item(0)->childNodes->item(0)->nodeValue . "</a>";
} else {
$hint=$hint . "<br /><a href='" .
$z->item(0)->childNodes->item(0)->nodeValue .
"' target='_blank'>" .
$y->item(0)->childNodes->item(0)->nodeValue . "</a>";
}
}
}
}
}
// Set output to "no suggestion" if no hint was found
// or to the correct values
if ($hint=="") {
$response="no suggestion";
} else {
$response=$hint;
}
//output the response
echo $response;
在here中,我尝试使用<table name="set">
<column name="the_title">Title</column>
<column name="unit_url">example.com</column>
</table>
,但无法将其付诸实践...
如何使用实时搜索显示按属性收集的数据?
