Add any text to span within a div by jQuery

Do to add some text to the span of the code below?

<span>**tag cloud**</span>

You can use:  $(“#tagscloud span”).text(“Your text here”);

The same code will also work for the second case. You could also use:

$(“#tagscloud #WebPartCaptionWPQ2”).text(“Your text here”);

You can also use this code:

The .append() method inserts the specified content as the last child of each element in the jQuery collection (To insert it as the first child, use .prepend()).

$("#tagscloud span").append(second);
$("#tagscloud span").append(third); 
$("#tagscloud span").prepend(first); 
Careful – append() will append HTML, and you may run into cross-site-scripting problems if you use it all the time and a user makes you append('<script>alert("Hello")</script>').
Use text() to replace element content with text, or append(document.createTextNode(x)) to append a text node.

For Example(See Pictures Blew):

In my case, I want to add “price:” text before this text
Now, I need to see what html design we have. To see html design I need to inspect Element of this page. So, i will Right click ok this text then I will click on Inspeck.
If i wan to add “Price:” text before the Prie Symbol I should add the “.prepend(‘price’);” code. Or  If I wan to add “Price:” text after the symbol then I should use “.append(‘price’);” this code. 
So, Let’s do it. 
1. So, first i need to pick this “woocommerce-Price-currencySymbol” from inspeck elament 
2. Then write on your on custom js file. I added my code in my theme’s custom js option.

<script> jQuery(function($){ $(‘.woocommerce-Price-currencySymbol‘).prepend(‘Price:’); }); </script>

Here, It’s Dome.
