dan*_*ark 5 javascript arrays ajax jquery json
我试图找出如何访问基本上多维JSON数组中的数据.
我的jQuery AJAX请求如下所示:
$("#login-form").submit(function(e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: '/ajax/login',
data: 'email='+$("#email").val()+'&password='+$("#password").val(),
success: function(data){
// FIRE ALERT HERE
alert(data.firstname);
},
dataType: 'json'
});
});

正如你所看到的,我正在警告第一个名字,这很好.我可以通过使用data.key访问第一维中的所有内容,但我不知道如何我需要索引下一个维度.显然我想以某种方式展示每个产品.
建议是最受欢迎的.
在 success 函数中,您可以将 JSON 数据视为 JavaScript 对象。您可以像这样访问产品数组及其内部的对象:
console.log(data.products + " product(s) in data"); // data.products is 2 (integer)
for(var i = 0; i < data.products; i++) { //
var product = data[i.toString()]; // 0.toString() is "0"
// data["0"] is what you want
// now product points to the property "0"
console.log(product.product_no); // so you can use product.xxx
// or product["xxx"]
} // likewise for "1", "2", "3" and so on

如果您不知道控制台是什么,请替换为console.log。alert
