如何访问AJAX的数组响应

Question

这是我的AJAX调用响应,它采用数组格式

[1,2,3,4,5,6]

success: function(outputfromserver) {


$.each(outputfromserver, function(index, el) 
{ 


});

我们怎样才能访问outputfromserver的所有值？

表示outputfromserver Zeroth值为1,第二个元素为2,-----依此类推

了解您的AJAX请求是什么样子会有所帮助.我建议使用$ .ajax()并将dataType指定为JSON,或使用$ .getJSON().

下面是一个演示$ .ajax()的示例,并向您展示如何访问数组中返回的值.

$.ajax({
    url: 'test.json', // returns "[1,2,3,4,5,6]"
    dataType: 'json', // jQuery will parse the response as JSON
    success: function (outputfromserver) {
        // outputfromserver is an array in this case
        // just access it like one

        alert(outputfromserver[0]); // alert the 0th value

        // let's iterate through the returned values
        // for loops are good for that, $.each() is fine too
        // but unnecessary here
        for (var i = 0; i < outputfromserver.length; i++) {
            // outputfromserver[i] can be used to get each value
        }
    }
});

现在,如果您坚持使用$ .each,则以下内容适用于成功选项.

success: function (outputfromserver) {

    $.each(outputfromserver, function(index, el) {
        // index is your 0-based array index
        // el is your value

        // for example
        alert("element at " + index + ": " + el); // will alert each value
    });
}

随意问任何问题!
