JQuery 未知 "this" 内 ajax 请求
JQuery unknown "this" inside ajax request
我需要在发出 ajax 请求后更改 class 属性,但我无法在 Ajax 请求
中访问 "this"
$('.shopping').click(function(){
//Get id attribute
var id = $(this).attr('id');
//Send id attribute in Ajax request
$.get('processAddToShopping.php?id='+id, function(data){
if(data == "success"){
//Change attribute if success
$(this).attr('class', 'new'); //CAN'T access "this" anymore
}
});
});
设置上下文变量:
$('.shopping').click(function(){
//Get id attribute
var id = $(this).attr('id');
var that = this;
//Send id attribute in Ajax request
$.get('processAddToShopping.php?id='+id, function(data){
if(data == "success"){
//Change attribute if success
$(that).attr('class', 'new');
}
});
});
因为你已经有了 'id' 属性,你可以通过 id 找到 DOM 元素:)
$("#"+id).attr('class', 'new');
