I have a code editor written in JavaScript on my page and I want to
send the code that it is typed in as a string to IronPython so that it
can be executed from IronPython. I got this to work in C# but not in
IronPython. Below is the JavaScript I use:
<script type="text/javascript">
var textarea = document.getElementById('code');
var editor = new CodeMirror(CodeMirror.replace
(textarea), {
height: "350px",
width: "500px",
content: textarea.value,
parserfile: ["tokenizejavascript.js",
"parsejavascript.js"],
stylesheet: "css/jscolors.css",
path: "js/",
autoMatchParens: true
});
function invokeManagedCode() {
var form = document.getElementById("editor");
var user = form.user.value;
var control = document.getElementById("sl2");
control.Content.codeProvider.Code(editor.getCode
());
}
</script>
The code replaces a standard HTML-textarea with the JavaScript editor.
The function "invokeManagedCode()" sends the text in the code editor
to a C# method. The C# code is really simple:
namespace htmlDom1
{
public partial class Page : UserControl
{
public Page()
{
InitializeComponent();
HtmlPage.RegisterScriptableObject("codeProvider", this);
}
[ScriptableMember()]
public void Code(string codeString)
{
this.Message.Text = codeString;
}
}
}
How can I achieve the same in IronPython? I tried to do exactly the
same as in C#. See below:
[ScriptableMember()]
Although this is valid Python syntax, it doesn't do what you think...
(It actually created a new list - but as you don't assign a name to it,
it will be garbage collected.)
Unfortunately we can't apply attributes to Python classes. I get round
this particular problem by creating stub classes in C# and inheriting
from them in Python. See:
http://www.voidspace.org.uk/ironpython/silverlight/scriptable.shtml
All the best,
Michael
def Code(codeString):
root.sl2TextBox.Text = codeString # Show that it works by writing
the string
# from the
javascript code editor to a Silverlight textbox
HtmlPage.RegisterScriptableObject("codeProvider", Code)
But this doesn't work. How to do it properly?
Thanks for help!
