    selection to node

    Reply Quote

    Is it possible to get the first node from editor.GetRangePreviewHTML(); or get the selected node from the editor.
    I have made a custom element so to speak and I want to check the selection so that when you select this element you still get the same dialog but you edit the node instead of wrap it with the same node.

     

    For example I have a button wich changes selected text into:

    1. <footnote data-somevar="dialog value">selected text</footnote>  

    If you press the button again if you select the footnode or focus inside it you will get something like :&

    1. <footnote data-somevar="dialog value">
    2.     <footnote data-somevar="dialog value">selected text</footnote>
    3. </footnote>   
     And I don't want that.

    I'll do the custom Mark function, this opens a dialog wich allows you to mark the word you selected for later indexing and add a description.

    This is the one with the least amount of javascript.

    I still have to replace the handwritten html with "

    var element = editor.GetFrame().contentDocument.createElement("mark");

    " . But I first want the right functionality.

    1. var editor;  
    2. function RichTextEditor_OnLoad(rteeditor) {  
    3.     editor = rteeditor;  
    4.     editor.AttachEvent("ExecUICommand", CaptureSaveEvent);  
    5. }  
    6. function CaptureSaveEvent(rteeditor, info) {  
    7.     if (!rteeditor) return;  
    8.     if (!info || !info.Arguments || !info.Arguments[1]) return;  
    9.   
    10.     if (info.Arguments[1] == "DoMark") {  
    11.         // Todo edit if mark selected  
    12.   
    13.         var oldvalue = editor.GetRangePreviewHTML();  
    14.         editor.ShowXmlDialog("/richtexteditor/dialogs/mark.xml", {  
    15.             value: oldvalue,  
    16.             confirm: function (markvalue) {  
    17.                 if (!!markvalue && markvalue.trim() != "") {  
    18.                     var newvalue = "<mark data-value=\"" + markvalue + "\">" + oldvalue + "</mark>";  
    19.                     var insert = editor.InsertHTML(newvalue, true);  
    20.                     insert[0].Ox13.focus(0);  
    21.                     insert[0].Ox13.selectionStart = 0;  
    22.                     insert[0].Ox13.selectionEnd = 0;  
    23.                     editor.ExecCommand("CleanCode");  
    24.                 }  
    25.             }  
    26.         });  
    27.     }             
    28. }

    Dear Marvin,

     

    I write a demo with mark

     

    1. if (info.Arguments[1] == "DoMark") {  
    2.     var nodes = editor.ExtractRangeNodes(false);  
    3.     var pointnode = editor.GetPointNode();  
    4.     if (nodes.length == 0) 
    5.        return; 
    6.     var root = pointnode;  
    7.     if (!root.Contains(nodes[0]))  
    8.         root = root.GetParent();  
    9.     if (nodes.length == 1) {  
    10.         //select 1 node  
    11.         if (nodes[0].GetName() == "mark" || (root.GetName() == "mark" && root.GetChildCount() == 1)) {  
    12.             //self is mark node  
    13.             alert(root.GetName() == "mark" ? root.GetAttribute("data-value") : nodes[0].GetAttribute("data-value"));  
    14.         }  
    15.         else {  
    16.             var mark = editor.ParseHtmlCode("<mark data-value=\"1\"></mark>")[0];  
    17.             editor.SurroundNode(mark);  
    18.             editor.Focus();  
    19.         }  
    20.     }  
    21.     else {  
    22.         //select multiple nodes  
    23.         if (root.GetName() == "mark" && root.GetChildCount() <= nodes.length) {  
    24.             //surround with mark node  
    25.             alert(root.GetAttribute("data-value"));  
    26.         }  
    27.         else {  
    28.             var html = editor.ExtractRangeHTML(true);  
    29.             var mark = "<mark data-value=\"2\">" + html + "</mark>";  
    30.             editor.InsertHTML(mark);  
    31.             editor.Focus();  
    32.         }  
    33.     }  
    34. }  
     

     

    Regards,

    Jeff

    Thank you very much!
    I've made some modifications so it erases all the mark's inside if you select multiple mark's and you can now edit them.
    It's probably not the most efficient way to go but I'm still learning the editors API. 

     

    With kind regards,

    Marvin Brouwer.
