Pb28 Favorite Star Rating with jQuery
This tutorial has a jQuery code for doing favorite star ratings. It displays a list of HTML stars by using li tags. These stars are highlighted using CSS and jQuery based on the user’s favorite rating.
HTML Code for Displaying Rating Stars
This HTML code displays a list of rating stars by using an HTML star entity and LI tags.
html
<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 preserves the selected rating count on clicking stars.
jQuery Favorite Star Rating Functions
These are the jQuery functions we use in this example to handle favorite star ratings.
javascript
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 receive selected HTML element objects from the function call and change the star status based on the rating stars selected.
