How to deal with Ajax submission garbled code under IE

This time I will show you how to deal with garbled codes submitted by Ajax under IE. What are the precautions for dealing with garbled codes submitted by Ajax under IE. The following is a practical case, let's take a look.

Haha, after trying so many things, encodeURIComponent still works! ! ! !

Add a protective measure to the position of Chinese characters: encodeURIComponent(parentid)

function loadCity(parentid) {
	var city = '${hotel.city}';
	
  $.ajax({
    url: './listCity.jspx?prov='+ encodeURIComponent(parentid),
    type: 'GET',
    dataType: 'JSON',
    timeout: 5000,
    error: function() { alert('加载城市列表失败!'); },
    success: function(msg) {
$("#city").empty();
$.each(eval(msg), function(i, item) {
	if(item.city ==city){
		$("<option value=&#39;" + item.city + "&#39; selected = &#39;selected&#39;>" + item.city + "</option>").appendTo($("#city"));
	}else{
		 $("<option value=&#39;" + item.city + "&#39;>" + item.city + "</option>").appendTo($("#city"));
	}
  
});
    }
  });
}

Another method of adding contentType mentioned on the Internet seems to be irrelevant Use, o(︶︿︶)o Oh, it’s better to rely on yourself~~

contentType: 'application/x-www-form-urlencoded; charset=utf-8',
