I want to show the confirmation window for the user who want to delete the data from database. 

And I use this confirm() function to achieve this: 

```
var str = document.getElementById("myHiddenDiv").innerHTML;

if (confirm(str))
    {
        $.ajax(...

<div id="myHiddenDiv" style="display: none;"><strong>Dont delete this</strong>
<br />
...
</div>

```

However it prints the html attribute in the windows confirmation such as the tag of `<strong>` and `<br/>`. I don't want that. How to do that?
