any appreciated

i assume know how parse out ratings, right? if displaying single star values (whole numbers), can write out class onto span element style css change background image be.

so, make show 1-5 stars 4 different images.

it's solution; not cleanest or scalable, works situation.

so first off nightmare.

let's clean bit? 

var appendstring = []; appendstring[0] =  "<img src='"+hotel2show.imgurl+"'>"; appendstring[1] = "<p id='name'><strong>"+ hotel2show.name +"</strong></p><br/>"; switch(hotel2show.rating): case(1): appendstring[2] = "<p id='rating' class='rating-1'><strong>"; break; case(2): appendstirng[2] = "<p id='rating' class='rating-2><strong>"; break; //etc   appendstring[3] = hotel2show.rating +"</strong></p>"; appendstring[4] = "<br/><br/>"; appendstring[5] = "<p id='price'><strong>'&pound;'" + hotel2show.price + "</strong></p>"; appendstring[6] = "<p id='text'><strong>"+ 'total hotel stay' +"</strong></p>"; document.getelementbyid("img-container").innerhtml = appendstring.join(' ');

note: switch statement syntax may incorrect.
