Favorite Star Rating with jQuery
by Vincy. Last modified on July 12th, 2022.
In this tutorial, we are having a jQuery code for doing favorite star rating. It displays a list of HTML stars by using li tags. These stars are highlighted by using CSS and jQuery based on the favorite rating selected by the user.
HTML Code for Displaying Rating Stars
This HTML code displays a list of rating star by using HTML star entity and LI tags.
<input type="hidden" name="rating" id="rating" />
<ul onMouseOut="resetRating();">
<li onmouseover="highlightStar(this);" onmouseout="removeHighlight();"
onClick="addRating(this);">★</li>
<li onmouseover="highlightStar(this);" onmouseout="removeHighlight();"
onClick="addRating(this);">★</li>
<li onmouseover="highlightStar(this);" onmouseout="removeHighlight();"
onClick="addRating(this);">★</li>
<li onmouseover="highlightStar(this);" onmouseout="removeHighlight();"
onClick="addRating(this);">★</li>
<li onmouseover="highlightStar(this);" onmouseout="removeHighlight();"
onClick="addRating(this);">★</li>
</ul>
The hidden input is used to preserve the selected rating count on clicking stars.
jQuery Favorite Star Rating Functions
These are the list of jQuery functions we are using in this example to handle favorite star rating.
function highlightStar(obj) {
removeHighlight();
$('li').each(function(index) {
$(this).addClass('highlight');
if(index == $("li").index(obj)) {
return false;
}
});
}
function removeHighlight() {
$('li').removeClass('selected');
$('li').removeClass('highlight');
}
function addRating(obj) {
$('li').each(function(index) {
$(this).addClass('selected');
$('#rating').val((index+1));
if(index == $("li").index(obj)) {
return false;
}
});
}
function resetRating() {
if($("#rating").val()) {
$('li').each(function(index) {
$(this).addClass('selected');
if((index+1) == $("#rating").val()) {
return false;
}
});
}
}
In these functions, we are receiving selected HTML element object from the function call and change the star status based on the rating stars selected.
Star Rating Styles
We are using these styles in this star rating example.
li {
display: inline-block;
color: #F0F0F0;
text-shadow: 0 0 1px #666666;
font-size: 30px;
}
.highlight, .selected {
color: #F4B30A;
text-shadow: 0 0 1px #F48F0A;
}
