Updating User Rating - Unexpected Token (Function Call Issue?)

Recommended Posts

So I have been writing my own code (ie not from the book) and am trying to use Ajax to do a star rating. My problems it that I keep on getting the following error:

 

 

Uncaught SyntaxError: Unexpected token (

 

I have pointed out which line below is giving me the error but I am having problems finding out where the core of my problem is.. I have had problems before with defining functions and calling them. Why am I getting this error? I just want to call the newStarRating function at this point with the given parameters. Any help would be appreciated! For the record I realize there may be multiple problems with my code as I am a beginner.

 

 

U.addEvent(U.$('rating_star_1'), 'mouseover', function(){ newStarRating(1, "yellow_full"); } );
U.addEvent(U.$('rating_star_2'), 'mouseover', function(){ newStarRating(2, "yellow_full"); } );
U.addEvent(U.$('rating_star_3'), 'mouseover', function(){ newStarRating(3, "yellow_full"); } );
U.addEvent(U.$('rating_star_4'), 'mouseover', function(){ newStarRating(4, "yellow_full"); } );
U.addEvent(U.$('rating_star_5'), 'mouseover', function(){ newStarRating(5, "yellow_full"); } );
U.addEvent(U.$('rating_star_6'), 'mouseover', function(){ newStarRating(6, "yellow_full"); } );
U.addEvent(U.$('rating_star_7'), 'mouseover', function(){ newStarRating(7, "yellow_full"); } );
U.addEvent(U.$('rating_star_8'), 'mouseover', function(){ newStarRating(8, "yellow_full"); } );
U.addEvent(U.$('rating_star_9'), 'mouseover', function(){ newStarRating(9, "yellow_full"); } );
U.addEvent(U.$('rating_star_10'), 'mouseover', function(){ newStarRating(10, "yellow_full"); } );
<?php

if (mysqli_num_rows($already_reviewed_query_result) == 1) {
	 echo "U.addEvent(U.$('star_rating_div'), 'mouseout', function(){ newStarRating(" . $current_user_review_rows['review_score'] .", 'blue'); } );";
 }
 else {
	 echo "U.addEvent(U.$('star_rating_div'), 'mouseout', function(){ newStarRating(0, 'yellow_full'); } );";
	 echo "/* \$already_reviewed_query is:*" . $already_reviewed_query . "*/";
 }
 mysqli_close($dbc);
?>





function newStarRating(starNumber, color) {
 'use strict';
 var i = null;
 for (var i = 1; i <= 10; i++) {
	 document.getElementById('rating_star_' + i).src='../images/white_star_17px.png';
 } //end of star color reset

 var j = null;
 for (var j = 1; j <= starNumber; j++) {

	 document.getElementById('rating_star_' + j).src='../images/' + color + '_star_17px.png';

 }

}

function starSubmitFxn(starNumber) {
'use strict';

//Get a reference (get element by ID) to the entered username value:
var ajax = getXMLHttpRequestObject();


var currentUsername = '<?php echo $current_username ?>';
var currentEntityId = '<?php echo $entity_id ?>';


		 ajax.onreadystatechange = function() {
			 if (ajax.readyState == 4){
				 //Check the status code:
				 if ( (ajax.status >= 200 && ajax.status < 300) || (ajax.status == 304) ) {
					 for ( var r = 1; r <= 10; r++){
						 if (ajax.responseText == r) {
							 newStarRating(r, "blue");//end of newStarRating call
							 } //end of response text check
						 } //end of loop

					 } //end of Ajax connectivity check
				 } //end of Ajax ready state
			 }; //end of function for execution on ready state change

error line-> var data = 'currentUsername=' + encodeURIComponent(currentUsername) + '&currentEntityId =' + encodeURIComponent(currentEntityId)
					 + '&starNumber =' encoreURIComponent(starNumber);
		 ajax.open('POST', 'resources/star_submit.php?' + data, true);
		 ajax.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');

		 ajax.send(data);
}//End of verifyUsername() function

Generally, that error comes about when there is a mismatch with your curly braces. In other words, you're probably missing a curly brace, semicolon or some other essential grammatical structure somewhere.

 

I'd start commenting out parts of your code until you can localize the error.

Good luck.

Found two of the problems. First of all one of my encodeURIComponent functions is misspelled encoreURIComponent, and I am missing the concatenation operator on that last encodeURIComponent.There still seems to be some other issues so I'm digging in deeper for that. JSLint / JSHint have been a help and I will utilize them in the future.
