I am using php and trying to fetch a value in a javascript function. The javascript in the HTML page is the following:
<script type="text/javascript">
function show(q)
{
if(q.length > 0)
{
if(q.indexOf("tid") > -1)
{
location.href = "map.jsp?" + q;
}
else
{
location.href = "listmap.jsp?" + q;
}
}
return false;
}
$(function() {
$("#map").goMap({
latitude: -35.331415
,longitude: 149.131851
,maptype: 'ROADMAP'
,scrollwheel: false
,zoom: 11
,markers: [ {latitude: -35.192103,longitude: 149.332313,icon: 'images/m/marker1.png',html: {content: 'Loading...', ajax: 'mapinfo.jsp?sid=9057'}}]
I need to get the values of (3rd and 4th lines in second function) the latitude and longitude which are: -35.331415 and 149.131851
I'm just not sure how to access the individual values...
EDIT: I AM USING PHP to save these values in variables then later write them to a csv file Currently i'm using this code (here's a snippit) to get everything else on other pages
<?php
$ch = curl_init("http://pvoutput.org/listmap.jsp?sid=312");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$cl = curl_exec($ch);
$dom = new DOMDocument();
@$dom ->loadHTML($cl);
$Lat_data = $dom -> getElementsByTagName("script");
print_r($Lat_data -> item(1) );
EDIT 2: I fixed all the problems by doing this:
$Lat_data = $dom -> getElementsByTagName("script");
$content =$Lat_data -> item(10) -> textContent;
$regex = "/latitude: ([^\b,]*)/";
if (preg_match( $regex , $content , $values )) {
echo $values[1];
$regex2 = "/longitude: ([^\b,]*)/";
}
if (preg_match($regex2, $content, $values2)) {
echo $values2[1];
}
You managed to get the script node. Now you want its content (the javascript code)
$content = $Lat_data -> item(1) -> textContent
Once you got the content you can parse it using regex expression to get what you want
$regex = "/latitude: ([^\b\n]*)(.|\n)*,longitude: ([^\b\n,]*)/";
if (preg_match($regex, $content, $values)) {
echo 'latitude: ' . $values[0];
echo 'longitue: ' . $values[2];
}
regex explanation (test here ):
this regex explanation is getting a little messy, check the test link to more detailed explanation.
I have not tested it so there might be some syntax error but the idea is there ;)
实施一些ajax将js文件中的经度和纬度提交到php文件中,效率会更高吗?
