问题描述

将json从php解析为javascript时遇到问题

i have a problem when parsing json from php to javascript

这是我的示例代码:

//function
MethodAjax = function (wsFile, param) {
    return $.ajax({
        type: "POST",
        dataType: "json",
        url: '../proses/' + wsFile + ".proses.php",
        data: 'param='+param,
        error: function (msg) {
            return;
        },
    });
};

//call function 
$(document).ready(function() {

    $('#getproduk').click(function(){
        var param = {
        ProdukId : '1',
        ProdukName : 'test'
    };

    CallMethodWithAjax('try', JSON.stringify(param)).done(function(data){
        $data =  JSON && JSON.parse(data) || $.parseJSON(data); 
    });
});

//Simple Php code
<?php
    $data = $_POST['param'];

    $data = (json_decode($data));

    $data1['name'] = $data->ProdukName;
    $data1['id'] = $data->ProdukId;
    $data1['test'] = 'test';


    echo json_encode($data1);
?>

//post, response and error at console
response : {"name":"test","id":"1","test":"test"}
post : param    {"ProdukId":"1","ProdukName":"test"}
error : SyntaxError: JSON.parse: unexpected character at line 1 column 2 of the JSON  data

推荐答案

jQuery的 $ .ajax()函数将在响应为JSON时产生JavaScript对象，因此我认为您看到的错误是尝试解析JavaScript对象而不是您期望的字符串的结果.在提供给done函数的回调中，检查data，您会发现它是一个对象，不需要JSON.parse结果.

jQuery's $.ajax() function will yield a JavaScript object if the response is JSON so I believe the error you're seeing is a result of trying to parse a JavaScript object and not a string as you're expecting. In the callback you're providing to the done function, inspect data and you'll find that it's an object and there is no need to JSON.parse the result.
