problem with event handlers in dojo

I have a span inside which i have a achor tag.For anchor tag , i have used DojoAttachEvent,Now somwhere in my code i replace innerHTML of span as show below.

<span id ="xyz"> <a dojoAttachEvent="onmouseover:_myfunction"> txt223 </a> </span>

Now i replace text of span as follows:

var tmptxt = dojo.byId("xyz").innerHTML
dojo.byId("xyz").innerHTML = "some more txt" +tmptxt

Now after running this code the function _myfunction doesnot get called when onmoveover gets triggered.

I know that i can get away with the problem by using two spans ,one for next txt and one for anchor , but due to some css issues(i get each span on new line,its some two colum css and if i use 2 spans txt and anchor come on 2 different line which we dont want) i cant do it.

I tried to use dojo.connect , but the problem is as my span is present in some wizard the event gets triggered when am on page other then the page whi开发者_开发百科ch is the current page of wizard.

Try this code.it may helps.

<span id ="xyz"> <a dojoAttachEvent="onmouseover:_myfunction();return true;"> txt223 </a> </span>

First of all, if this isn't inside a widget template, dojoAttachEvent isn't what you want - you probably want something more like onMouseOver="_myfunction();".

Secondly, if you're replacing the innerHTML of the parent node of the node in question with the event, then naturally you're going to end up clobbering that node out of existence, and the event along with it, and you'd have to hook it up again one way or another. Is there a reason you can't be more careful with your DOM manipulation? Like, put an id on the a tag (or query for it from the span) and change only that node's innerHTML?
