I get NaN when I try to insert some HTML into a DIV element with jQuery
- by Ankur
I am tring to display a text box when a element of class numObj is clicked. For some reason I get NaNNaNaNaNNaNNaNaNaN where I expect to the see the result of the searchForm variable in the code below.
I know that NaN stands for Not a Number. What I don't understand is why is Javascript expecting a number? I can't understand why it cares.
$(".numObj").live('click',function(){
var preId = $(this).attr('preId');
var arrayPos = $(this).attr('numArrayPos');
alert(preId +" "+arrayPos);
var searchForm = "<table border='0' cellspacing='0' cellpadding='4' id='add-tag2'>"+
+"<tr class='normal'><td bgcolor='#EEEEEE' valign='bottom' nowrap='nowrap'><span class='normal-small'>"+
+"<input name='predicate-name2' type='text' class='normal' id='predicate-name2' size='4' />"+
+"</span></td>"+
+"<td bgcolor='#EEEEEE' valign='bottom' nowrap='nowrap'><span class='normal-small'><=</span></td>"+
+"<td bgcolor='#EEEEEE' valign='bottom' nowrap='nowrap'>x</td>"+
+"<td valign='bottom' bgcolor='#EEEEEE'><=</td>"+
+"<td valign='bottom' bgcolor='#EEEEEE'><span class='normal-small'>"+
+"<input type='text' name='object-object2' id='object-object2' class='normal' size='4' />"+
+"</span></td>"+
+"</tr>"+
+"</table>";
$(".numObj").filter("[preId='"+preId+"']").filter("[numArrayPos='"+arrayPos+"']").html(searchForm);
});
The generated code that has the numObj class looks something like this
<td><div class="numObj" preid="73" numarraypos="5"><span class="normal">585.0</span></div></td>
