Why
var offer=document. getElementById( "editor_display ing_text").valu e;
returns undefined?
Thank You

it's really hard to tell without knowledge of what "editor_display ing_text" is.Originally posted by oll3i
I'm going to go on a limb and say not all elements have a property called "value"... in fact, most do not. Unless "editor_display ing_text" is an "OBJECT", "PARAM", "LI", "INPUT" or "BUTTON", value will return undefined.
Read the DTD: http://www.w3.org/TR/html/DTD/xhtml1-transitional.dt d, do a CTRL-F for "value" and see how often it shows up.... not very often.
You may want to check out the "childNodes " array for a list of dom elements within the element -- or, if you like the cheap & easy way out, innerHTML. -
It's an editable div which id is editor_displayi ng_text

You'll have to show your code. Where do you define it within the page?Comment

Code:function makeBold(txt){ var offer=document.getElementById("editor_displaying_text").value; offer=offer+'\n' ; offer=offer.replace(txt,'<b>'+ txt +'</b>'); document.getElementById("editor_displaying_text").value = offer; }Comment

No, I didn't mean you did something wrong (in fact, quite the opposite)! I was in the middle of replying and by the time I replied, you'd already done so. I just added an edit in case it looked like a duplicate response.Originally posted by ronverdonkComment

it is just my attempt to write a simple editorCode:<script language = "JavaScript"> function getSelectedText(){ var txt = ''; if (document.getSelection) txt = document.getSelection(); else if (document.selection) txt = document.selection.createRange().text; return txt; } function makeBold(txt){ var offer=document.getElementById("editor_displaying_text").value; document.write(offer); offer=offer+'\n' ; offer=offer.replace(txt,'<b>'+ txt +'</b>'); document.getElementById("editor_displaying_text").value = offer; } </script> </HEAD> <BODY> <form name="editor"> <input type="button" name="bold" class="editor_bold" onClick="makeBold(getSelectedText())"> <input type="button" name="unordered_list" class="editor_unordered_list"> <input type="button" name="anchor" class="editor_anchor"> </form> <div id="editor_displaying_text" contenteditable="true" indicateeditable="true"></div>

Lol, you never know these days how people are easily offended.Originally posted by ronverdonk
Oll3i, as tswaters mentioned earlier, the div tag doesn't have a value attribute. Either use innerHTML or the DOM methods.
One other thing, you can't use document.write after the document has loaded.Comment
