in a html page, i have
<html>
<script>
var cnt=''+document.documentElement.innerHTML+'';
cnt=cnt.replace(......);
</script>
<body> something else</body>
</html>
how to use replace function above, so that my 'cnt' var content is like below
<html>
<body> something else</body>
</html>
window.onload = function(){
var body = String(document.body.innerHTML).replace("...");
document.body.innerHTML = body;
}
String.replace() is not powerful enough for your case. Use this function:
function stripTags(var s) {
var start = '<' + s + '>';
var end = '</' + s + '>';
while (true) {
var pos1 = s.indexOf(start);
var pos2 = s.indexOf(end);
if (pos1 == -1 || pos2 == -1) { break; }
s = s.substring(0,pos1) + s.substring(pos2+end.length);
}
return s;
}
This allows to remove all text in a specific element (script in your case).
