我有这个函数将数据发送到php文件,但由于某种原因,似乎php文件没有获得jquery发送给它的数据。
这是jquery代码:
<script type="text/javascript" src="JS/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".hide").hide();
$("#cake").hide();
var boz = $('#cake').val();
var search = $('#search').val();
$.get("petition_send.php", { id: boz, q: search }, function(data){
alert("Data Loaded: " + data);
});
$('.show').click(function checkPass(){
$(".hide").slideDown();
});
});
</script>
现在,这是php文件:
<?php
$xmlDoc = new DOMDocument();
include_once("petitionhint.php");
$xmlDoc->loadXML($xmlout);
$x=$xmlDoc->getElementsByTagName('friend');
//Get the q parameter from URL
$q = $_GET["q"];
$id = $_GET["petition_ID"];
//Lookup all links from the xml file if length of q>0
if(strlen($q)>0)
{
$hint = "";
for($i=0; $i<($x->length); $i++)
{
$y=$x->item($i)->getElementsByTagName('name');
$z=$x->item($i)->getElementsByTagName('url');
$w=$x->item($i)->getElementsByTagName('photo');
$l=$x->item($i)->getElementsByTagName('location');
if ($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 .= "<br />";
}
$hint .= "<h1 id='poli'><a id='blue' href='";
$hint .= $z->item(0)->childNodes->item(0)->nodeValue;
$hint .= "&petition_ID='$id' >";
$hint .= $y->item(0)->childNodes->item(0)->nodeValue;
$hint .= "</a> <br /><a id='green'>";
$hint .= $l->item(0)->childNodes->item(0)->nodeValue;
$hint .= "</a>";
$hint .= "<br/><img width='30' height='30' id='schmidt' src='features/";
$hint .= $w->item(0)->childNodes->item(0)->nodeValue;
$hint .= "' /></h1>";
}
}
}
}
// Set output to "no suggestion" if no hint were found
// or to the correct values
if($hint == "")
{
$response = "No suggestions";
} else
{
$response = $hint;
}
//output the response
echo $response;
?>
当我尝试将“$ id”变量包含在php代码的部分中时:
$hint .= "&petition_ID=$id' >";
它没有出现。 $ id变量不会出现。
答案 0 :(得分:2)
您要发送参数id
(boz
)和q
(search
),但您正在阅读参数q
和petition_ID
答案 1 :(得分:2)
您没有从$ _GET中选择正确的元素:
$id = $_GET["petition_ID"];
到
$id = $_GET["id"];
和
$hint .= "&petition_ID='$id' >";
到
$hint .= "&petition_ID=$id' >";
也可以尝试jquery调用
$.get("petition_send.php", { "id": boz, "q": search }, function(data){
alert("Data Loaded: " + data);
或考虑将“id”更改为其他内容。
