选择内容到大写字母？

Question

我只是想知道是否有一个简单的解决方案已经将tinymce选定内容转换为大写字母的问题。

任何人都有解决方案吗？

PS：upperCase函数是已知的，但不会单独解决所选内容的tinymce设置。

这就是我想出了一些后摆弄

 // check if a node intersects the given range 
     rangeIntersectsNode: function (range, node) { 
      var nodeRange; 
      if (range.intersectsNode) { 
       return range.intersectsNode(node); 
      } 
      else { 
       nodeRange = node.ownerDocument.createRange(); 
       try { 
        nodeRange.selectNode(node); 
       } catch (e) { 
        nodeRange.selectNodeContents(node); 
       } 

       return range.compareBoundaryPoints(Range.END_TO_START, nodeRange) == -1 && 
        range.compareBoundaryPoints(Range.START_TO_END, nodeRange) == 1; 
      } 
     }, 


// Tinymce-Shortcut: (cmd/ctrl + shift +a) 
if (((mac && evt.metaKey)|| (!mac && evt.ctrlKey)) && evt.shiftKey && evt.keyCode == 65){ 

    if (!ed.selection.isCollapsed()) { 

     var selection = ed.getWin().getSelection(); // user selection 
     var range  = selection.getRangeAt(0);  // erste range 
     var start  = range.startContainer; 
     var start_offset = range.startOffset; 
     var end   = range.endContainer; 
     var end_offset = range.endOffset; 

     // Get all textnodes of the common ancestor 
     // Check foreach of those textnodes if they are inside the selection 
     // StartContainer and EndContainer may be partially inside the selection (if textnodes) 
     // concatenate those textnode parts and make toUppercase the selected part only 
     // all textnodes inbetween need to become upperCased (the nodeContents) 
     // Selection needs to be reset afterwards. 
     var textnodes = t.getTextNodes(range.commonAncestorContainer); 
     for (var i=0; i<textnodes.length; i++) { 
      if (t.rangeIntersectsNode(range, textnodes[i])){ 
       if (textnodes[i] == start && textnodes[i] == end) { 
        var text_content = start.textContent; 
        text_content = start.textContent.substring(0, start_offset) + text_content.substring(start_offset, end_offset).toUpperCase() + end.textContent.substring(end_offset); 
        textnodes[i].nodeValue = text_content; 
       } 
       else if (textnodes[i] == start){ 
        var text_content = start.textContent.substring(0, start_offset) + start.textContent.substring(start_offset).toUpperCase(); 
        textnodes[i].nodeValue = text_content; 

       } 
       else if (textnodes[i] == end){ 
        var text_content = end.textContent.substring(0, end_offset).toUpperCase() + end.textContent.substring(end_offset); 
        textnodes[i].nodeValue = text_content; 
       } 
       else { 
        // Textnodes between Start- and Endcontainer 
        textnodes[i].nodeValue = textnodes[i].nodeValue.toUpperCase(); 
       } 
      } 
     } 

     // reset selection 
     var r = ed.selection.dom.createRng(); 
     r.setStart(start, start_offset); 
     r.setEnd(end, end_offset); 
     ed.selection.setRng(r); 

     evt.preventDefault(); 
     return false; 
    } 
}
