Use JavaScript to Replace Classname Value

Question

I want to replace every occurrence of the numbers with the string: ???.

Here is an example string:

<em>Chelsea</em> 1-4 Atletico Madrid

How can I do this in JavaScript?

    <a href="https://www.google.com/url?sa=t&amp;source=web&amp;cd=9&amp;cad=rja&amp;ved=0CFEQtwIwCA&amp;url=http%3A%2F%2Fwww.whoateallthepies.tv%2Fchelsea%2F137070%2Fsuper-cup-chelsea-1-4-atletico-madrid-falcao-on-fire-as-blues-flop-in-monaco-photos-highlights.html&amp;rct=j&amp;q=chelsea&amp;ei=1odBUImpBIWA0AWM1oC4BA&amp;usg=AFQjCNEwdCCckt15XTkHSAf2fsUnGk9IJg&amp;sig2=IOrD6hfMrviW9ods0DG2dw" class="l" onmousedown="return rwt(this,'','0','','9','AFQjCNEwdCCckt15XTkHSAf2fsUnGk9IJg','IOrD6hfMrviW9ods0DG2dw','0CFEQtwIwCA',null,event)" title="Super Cup: Chelsea 1-4 Atletico Madrid – Falcao On Fire As Blues Flop In Monaco (Photos ...">Super Cup: <em>Chelsea</em> 1-4 Atletico Madrid – Falcao On <b>...</b></a>

Thanks in advance.

So basically you just want the text node, and not the HTML content, to be affected by the replace.

Unfortunately there is no simple method to get text nodes, unlike getElementBy* functions, so you have to search manually:

var elems = document.getElementsByTagName('*'), l = elems.length, i,
    children, m, j;
for( i=0; i<l; i++) {
  children = elems[i].childNodes;
  m = children.length;
  for( j=0; j<m; j++) {
    if( children[j].nodeType == 3) children[j].nodeValue = children[j].nodeValue.replace(/\d+/g,'???');
  }
}

You just want to replace all the numbers with ????

var text = "1-4 Atletico Madrid – Falcao On";
var replaced=text.replace(/\d/g, "???");
alert(replaced);

Use this as a jumping off point, since you'll only want to get the text, not the other html parts.
