Toggling div visibility individually with jQuery

I have a simple jQuery function that toggles a div's visibility when clicked. The problem with the function开发者_开发问答 is that it can't be applied to multiple items on the same page or they all toggle in tandem. Is there a way around this without having to assign a unique class to each instance?

jQuery:

 $(function(){
    $(".toggleThis").click(function(){
         $(".hiddenText").slideToggle("fast");
            $(this).html(function(i,html) {
                if (html.indexOf('+') != -1 ){
                   html = html.replace('+','-');
                } else {
                   html = html.replace('-','+');
                }
                return html;
            })
    });
}); 

html:

<p class="toggleThis">Blah blah + <p>
<div class="hiddenText">
<p>Blah blah</p>
</div>

css:

.hiddenText {display: none;}

Thanks!

Instead of this:

 $(".hiddenText").slideToggle("fast");

Use this:

 $(this).next(".hiddenText").slideToggle("fast");

This approach finds it relatively to the clicked element (using .next()), rather than all class="hiddenText". If there are elements in-between that aren't in your example, use .nextAll(".hiddenText:first") instead.
