Jquery not working on mobile browser

I have a following jquery code that runs fine on desktop but doesn't run on mobile browser on my wordpress website. It attaches a parameter on ajax based search box but not doing on mobile browsers. Any idea why?

script

jQuery(document).ready(function($){ 


    $(input.orig).mouseout(function() {

    var stt = $(this).val();        


setTimeout(function() { 
    $(a.asp_res_url).each(function() {        
   var $this = $(this);       
   var _href = $this.attr(href); 
   var _href2 = $this.attr(href).split('?')[0];
    $this.attr(href, _href2 + '?s='+stt);
        
    
});
}, 0);  
    
});
    
});
    
/script
