Hi
I want to change a webpage in javaScript, but in a special way. I want to
run a a javascript on a HTML-file and save the result into a new HTML-file.
for example:
HTML-file:
--------------------------
<html>
.
.
.
<body>
<div id="id1" style="position: absolute; top:452px; left:78px; width:80px;
height:80px;">this is div no 1</div>
<div id="id2" style="position: absolute; top:4px; left:712px; width:80px;
height:80px;">this is div no 2</div>
.
.
.
</body></html>
--------------------------
js-file/SCRIPT FILE
--------------------------
var id1 = document.getElementById('id1');
id1.style.left = '0';
id1.style.top = '0';
--------------------------
I want the result to be... HTML-result
--------------------------
<html>
.
.
.
<body>
<div id="id1" style="position: absolute; top:0px; left:0px; width:80px;
height:80px;">this is div no 1</div>
<div id="id2" style="position: absolute; top:4px; left:712px; width:80px;
height:80px;">this is div no 2</div>
.
.
.
</body></html>
--------------------------
The coordinates in the div 1 has changed.
(Is this possible at all?)
I want to do this in java that's why I tried rhino.
Java code
--------------------------
.
.
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("JavaScript");
.
.
engine.put("htmlfile", f);
//f is a HTML-file
engine.eval("var span = htmlfile.getElementById('span');"); //A test row
of javaScript
f = (File)engine.get("file");
//The result.. (which in this case should be exactly the same as the
HTML-file)
.
.
--------------------------
However I get a exception:
Exception in thread "main" javax.script.ScriptException:
sun.org.mozilla.javascript.internal.EcmaError: TypeError: Cannot find
function getElementById. (<Unknown source>#1) in <Unknown source> at line
number 1
"Cannot find function getElementById"?
am I dong something wrong or isn't getElementById implemented yet? (is this
possible to do in this way?)
