    attribute bad formed in JSON data

    Hi, I have a JSON data set parsed and at one point in the script I have this line:

    Code:
    <a class='dev' href="+page+" title='+title+' target=_blank>"+title+"</a>
    The problem is that in any JSON data set I use the attribute "title" is bad formed and the result is the only first word from the data set which contains the title data. Why is so ?

    make sure that title is a string, and that it does not contain an apostrophe, line break, or other invalid JSON string char.

    if you need to, you can escape it with the function below:

    Code:
    function jx (s) {
     if(!s.match){s=String(s);}
     var m = {'\b':"\\b", '	':"\\t", '\n':"\\n", '\f':"\\f", '\r':"\\r", '"':"\\\"", '\\':"\\\\"};
    	if (/["\\\x00-\x1f]/.test(s)) {
    	  return "\"" + s.replace(/([\x00-\x1f\\"])/g, function (a, b) {var c = m[b];if (c) {return c;}c = b.charCodeAt();return "\\u00" + Math.floor(c / 16).toString(16) + (c &#37; 16).toString(16);}) + "\"";
    	}
    	return s;
    }

    the code is this:
    Code:
    <script type="text/javascript">
      var ix=0
      function cback(obj)
      {
      var count=(obj.count);
      while (ix<count)
      {
      var title=(obj.value.items[ix].title);
      var pic=(obj.value.items[ix]["media:thumbnail"][0].url);
      var author = (obj.value.items[ix]["media:credit"][0].content);
      var page = (obj.value.items[ix].link);
      var pub = (obj.value.items[ix].pubDate);
      var dynDiv = document.createElement("div");
      dynDiv.id = "p"+ix+"";
      dynDiv.setAttribute('class',"SlidingPanelsContent")
      dynDiv.innerHTML = ("<div style='border: 1px solid #000000;width:300px;height:272px;text-align:center;padding:3px;'><img class='show' src="+pic+" alt="+title+"/><br><a class='dev' href="+page+" title="+title+" target=_blank>"+title+"</a><br><p class='dev'>by:  "+author+" on "+pub+"</p></div>")
      document.getElementById('dv').appendChild(dynDiv);
    
      ix=ix+1 ;
       }
       }
      </script>
    In this case for example the attribute 'alt' of the image is "Elegant" instead of "Elegant Visions" (in bold red and scroll right to find it).

    	}
    	return s;
    }
    Actually there is a space between words and that might explain it.

    I was trying to add attributes to the JSON parsed data such as "alt", "title" and other characteristics, but i gave up since this page isn't indexed by search engines or at least useful for the user. But I've noticed some strange results. For example when retrieving a value as "long words" the result looks like this:
    Code:
    title="long" words=""
