Hi Walter,

Actually I did it in JavaScript.
But I made a turn and now use inline rendering...
I guess this makes me quite an MVC-violator
but at least it solves my first problem
(no more whitespaces at the beginning, no tags inside textarea etc.).
The action for grabbing file paths and getting file output ready
now does not use a partial anymore but uses this line (simplified):
(1) using "onclick=" + JavaScript function:
render :inline => "<%= '<div id=\"'+timestamp+'\" class=\"ruby\"
onclick=\"createEditor()\">
'+file_contents+'</div>'%>",
:locals => {:timestamp => ts,
:file_contents =>
_get_file_contents(file_path,convert)}
So now I get dynamic IDs for each file/<div>.
However, problem no. 2 from last time still exists:
- Clicking once on the html-stuff created by above code
only adds 'title' + 'background-color' to the div.
- Clicking once again makes the textarea appear.
- Closing it and clicking one more time creates two textareas and so
on.
When I omit JavaScript and use a plain old Rails in_place_editor,
this phenomenon does not appear:
(2) using JavaScriptMacrosHelper::in_place_editor:
render :inline => "<%= '<div id=\"'+timestamp+'\" class=\"ruby\">
'+fcontents+'</div>'
+ in_place_editor(timestamp,
:url => url_for({:action => \"save_file\"}),
:load_text_url => url_for({:action => ...
However I then miss the ability to assign user specific values
for ":rows" and :"cols" (using screen resolution etc.)
and of course the possibilty to prevent this "all text selected" thing
inside the textarea.
This is quite important so I would hate to miss it...
The JavaScript function for creating the IPE looks like this:
function createEditor(preId,file_path) {
var size = paneSplitter.getSizeOfPaneInPixels('center');
var width = Math.round(size.width * 0.12);
var height = Math.round(size.height * 0.053);
var editor = new Ajax.InPlaceEditor(preId, file_path);
var bak = editor.createEditField;
editor.createEditField = function() {
bak.apply(this, arguments);
Event.observe(this.editField, 'focus', function(ev) {
if (this.setSelectionRange) {
setTimeout(function () {
this.setSelectionRange(0, 0);
}.bind(this), 10);
} else {
if (this.createTextRange) {
var range = this.createTextRange();
range.collapse(true);
range.moveEnd('character', 0);
range.moveStart('character', 0);
range.select();
}
}
}.bindAsEventListener(this.editField)
);
};
}
I deeply hope I explained my struggling well enough
so you might have a clue...
Thanks in advance,
Tom.
