例如,假设检索到的数据是整数2,我们希望使用以下代码将此值赋给变量'num':
$.ajax({
url: "index.php",
dataType: "JSON",
success: function(){
var num = ???;
}
})
你会用什么代替'???' ?
答案 0 :(得分:2)
响应作为参数传递给回调。只需定义一个参数:
success: function(response){
// "response" contains the response from the server
}
当然,您可以随意调用变量。

再给出一个更详细的例子:
$.ajax({
url: "index.php",
dataType: "JSON", //dataType only modifies what is coming BACK from PHP side
success: function(recd){
//if (recd.length > 0) alert(recd);
var num = recd.number; //or whatever that variable is called in the JSON
}
});
