I have a giant source file in HTML with javascript I'd like to extract some information from a javascript content. Considering I have a file like the following
<h1>Hello World</h1>
<script type="text/javascript">something useless</script>
<script type="text/javascript">var gmaps_vars = {FullAddress: "Rio de Janeiro, Rio de Janeiro, Brasil", GeoLocation: {"lng":-43.187554,"lat":-22.9470974}}</script>
How would I extract the latitude and longitude?
How about using regular expression:
m = /GeoLocation: \{"lng":(-?\d+\.\d+),"lat":(-?\d+\.\d+)\}/.match(html)
lng = m[1]
lat = m[2]
Try
html
<h1>Hello World</h1>
<script type="text/javascript">var a;</script>
<script type="text/javascript" id="vars">var gmaps_vars = {"FullAddress": "Rio de Janeiro, Rio de Janeiro, Brasil", "GeoLocation": {"lng":-43.187554,"lat":-22.9470974}}</script>
js
$(function() {
var coords = [];
$.post(url, function(data, textStatus, jqxhr) {
$.each($(data), function(index, value) {
if ($(value).is("#vars")) {
coords.push(JSON.parse($(value).text().replace(/var|gmaps_vars|\=/g, "")).GeoLocation);
console.log(coords[0].lng + "\n" + coords[0].lat);
};
});
});
});
