Hi,

How to extract number 2083236893 from  this object

<div class="gwt-Label">2083236893</div>

with GM ?


In the last few hours I have tested more than 20 examples, visited many websites and still no answer.

var x = document.getElementsByClassName("gwt-Label")[0].className;

fails

// var divs = document.getElementsByTagName('div')[0].innerHTML;
// var nrdivs = divs.length;

fails

I gave up XPath since I don't know how to apply XPath for this class, saved with firebug

Not sure why do I get 0 for these lines of code

var divs = document.getElementsByTagName('div');
var nrdivs = divs.length;

if web page in question comes with 10+ DIV objects

I feel myself exhausted :(

var divs = document.getElementsByTagName('div');
var nrdivs = divs.length;

try (untested)

var divs = document.getElementsByTagName('div');

var number= undefined;
// loop over all divs
for(var i=divs.length;i-->0;) {
  // className colud have mor in than just "gwt-Label", so use a regular expression
  if( divs[i].className.match(/\bgwt-Label\b/) ) {
    // got the number
    number= divs[i].textContent;
    // so we're done…
    break;
  }
}
if( number !== undefined ){
  // youhave it
} else{
  // Lots of divs but not the one we searched.
}

 

I, btw, prefer nowadays to @require jQuery which makes stuff like this more easy.
