    How to get "SRC" or URL or tag of selected image

    Reply Quote
    Hi,
     
    I have used the following code to get the src of a selected image:
     
    if(editselection.type=='Control')
     {
         if(range.length==1)
        {
            var element=range.item(0);
      
            if(element.tagName=='IMG')
           {
               // alert(element.src);
              textBox.value=element.src;
           }
        }
     }
     
    I would like to get the whole tag as I will be using it to create a URL
     
    This is the whole tag
    <img src="../filemanager/previewfile.ashx?id=57917&amp;thumb=true">
     
    This is returned by element.src;
     
    So, I have 2 problems:
     
    How do I get the whole tag out?
     
    How do I stop it from returning
    instead of
    ../filemanager/previewfile.ashx?id=57917&amp;thumb=true
     
    Thank you.

    the4bs,
     
    >>How do I get the whole tag out?
     
    There is such JavaScript API available.
     
    You need to write your own code.
     
    Tip: 

    For IE, please check outerHTML Property.

    outerHTML Property - Sets or retrieves the object and its content in HTML.

    Please use the following code:

         var src;
         src = element.getAttribute("src") + '' ;
         if(element.getAttribute("src_cetemp"))
          src = element.getAttribute("src_cetemp") + '' ;

    Please use the following code:

         var src;
         src = element.getAttribute("src") + '' ;
         if(element.getAttribute("src_cetemp"))
          src = element.getAttribute("src_cetemp") + '' ; 
     
    Thank you.
    That seems to work.

    function getSelectedHTML()   
    {      
          var rng=null,html="";         
          
          // get the active editor document
          var editdoc = editor1.GetDocument();

          // get the active editor window 
          var editwin = editor1.GetWindow();   
          if (document.selection && document.selection.createRange)   
          {      
                rng=editdoc.selection.createRange();   
               if( rng.htmlText )    
               {    
                  html=rng.htmlText;    
               }    
               else if(rng.length >= 1)    
               {    
                  html=    rng.item(0).outerHTML;    
               }   
          }   
          else if (window.getSelection)   
          {   
                rng=editwin.getSelection();   
                if (rng.rangeCount > 0 && window.XMLSerializer)   
                {   
                      rng=rng.getRangeAt(0);   
                      html=new XMLSerializer().serializeToString(rng.cloneContents());   
                }   
          }   
          return html;   
    }  
     
    Using above function I am able to get  selected html:
    http://cutesoft.net/developer+guide/scr/Get-HTML-from-Selection.htm
     
    Now, I need to add NAME and ID attribute to IMG element. 
     
    In IE, highlighted line gives IMG element DOM, but in Firefox no luck, any ideas?
     
    Thanks,
    Maulik

    Thanks for your response. 
     
    It does not seem to work though, I want to manipulate DOM of Image element and it seems to return something else.
     
    Any alternative?
