javascript - jQuery .prev() not working well -


i coding front-end of shopping website , scenario is: if have sale offer first previous price must line-through , beside price € inserted.

so jquery :

$(document).ready(function () {     if ($('.price span.price-new').text().length !=  '') {     this.prev('.price span.price-new').before("€").text();      this.prev("span").css({"text-decoration": "line-through"});  }       });

and html:

<?php                                                foreach( $this->products() $products)         { echo '<div class="price"><span class="price-old">€&nbsp;'.$products['price'].'</span>'. '<span class="price-new">'.$products['special_price'].'</span></div>'.'</div>';}?>

both of them didn't work. tried $(this) didn't work , because of have many price-new class can't mentioned specific class edit, use prevuntil still nothing.

shouldn't more this?

$(document).ready(function () {     $('.price-old').css({"text-decoration": "line-through"});     $('.price-new').text(function(index, old_text) {         return "€" + old_text;     }) });

(what code for?)
