[CLOSED] TextArea Selection Range

[softmachine2011]

Hi,

I need to know if there is any selection and the range of it in a textarea, in Ext.NET 1.x I do it like this:

addText: function (text) {
        var textArea = txtFormula.el.dom;
        if (document.selection) {
            textArea.focus();
            var sel = document.selection.createRange();
            sel.text = text;
        }
        else if (textArea.selectionStart || textArea.selectionStart == '0') {
            var startPos = textArea.selectionStart;
            var endPos = textArea.selectionEnd;
            textArea.value = textArea.value.substring(0, startPos)
                              + text
                              + textArea.value.substring(endPos, textArea.value.length);

        } else
            textArea.value += text;
    },

But know anything I'm trying doesn't satisfy my requirements.

NOTE: It has to work on IE and FF

Hi,

Is there any JavaScript error? For example, here?

var textArea = txtFormula.el.dom;

Should not you use

App.txtFormula

instead of

txtFormula

And, I think, you should use "inputEl" instead of "el".

No, there isn't any error because I have setted Namespace="" to avoid App namespace.

And the first case of the if conditional adds text in top of application not inside the textarea.

But at this moment I only need a form to get start and end index of selected text and I could rewrite the function.

Ok, applying the above causes the function working.

But at this moment I only need a form to get start and end index of selected text and I could rewrite the function.

This appears to be working in IE9.

txtFormula.inputEl.dom.selectionStart
txtFormula.inputEl.dom.selectionEnd

Anyways, there is no special things in Ext.NET to deal with the text selection, should deal directly with DOM.

Yes, it works with inputEl

Thanks

So, can we mark the thread as closed?
