Ajax with multiple parameters in Yii2


I am working on dynamic dropdownlist. There are 3 lists, the third list values are populated based on the first two lists inputs.

Below is the code.


                         $.get( "'.Url::toRoute('/site/findcarsfuel').'", { model: $(this).val(),mod: $(#signupform-model_name).val() } )

                             .done(function( data ) {

                                 $("select#'.Html::getInputId($signup, 'fuel').'").html( data );



signupform-model_name is the first lists id, this is not working. I am getting Uncaught SyntaxError: Unexpected token ILLEGAL.

Please help on this.
