jQuery加载json的数据

Question

我一直在尝试使用jQuery从json表中加载一些数据。

由于某种原因，它不起作用，但我相信我已经涵盖了每个方面？我希望这是一个语法错误，可能已经溜过了，而不是从我的角度来看。

这是我在这里：

HTML：

<table id="fixtures"> 
    <thead> 
    <tr> 
     <th>Home</th> 
     <th>Away</th> 
    </tr> 
    </thead> 
    <tbody> 
    </tbody> 
</table> 

的javascript：

var jsonDataUrl = 'http://bushell.net/football/site/includes/functions.php'; 

$(function() { 
    $.ajax({ 
    type: 'GET', 
    url: jsonDataUrl, 
    async: false, 
    jsonpCallback: 'JSON_CALLBACK', 
    contentType: "application/json", 
    dataType: 'json', 
    success: function(data) { 
     addRows($('#fixtures'), data, ['data.homeTeamName','data.awayTeamName']); 
    }, 
    error: function(e) { 
     console.log(e.message); 
    } 
    }); 
}); 

function addRows(table, data, fields) { 
    var tbody = table.find('tbody'); 
    $.each(data, function(i, item) { 
    tbody.append(addRow(item, fields)); 
    }); 
    return tbody; 
} 

function addRow(item, fields) { 
    var row = $('<tr>'); 
    $.each(fields, function(i, field) { 
    row.append($('<td>').html(item[field])); 
    }); 
    return row; 
} 

控制台错误：

Answer 1

检查我已经更新了类函数，因为你的Ajax没有工作，所以我加入了上面的虚拟数据。

http://jsfiddle.net/c2j1bc2h/

$(function() { 
data = [{'homeTeamName':'sdfds','awayTeamName':'dasdsa'},{'homeTeamName':'sdfds','awayTeamName':'dasdsa'},{'homeTeamName':'sdfds','awayTeamName':'dasdsa'},{'homeTeamName':'sdfds','awayTeamName':'dasdsa'},{'homeTeamName':'sdfds','awayTeamName':'dasdsa'},{'homeTeamName':'sdfds','awayTeamName':'dasdsa'},{'homeTeamName':'sdfds','awayTeamName':'dasdsa'},{'homeTeamName':'sdfds','awayTeamName':'dasdsa'},] 
addRows1($('#fixtures'), data, ['homeTeamName','awayTeamName']); 

function addRows1(table, data, fields) { 
    var tbody = table.find('tbody'); 

    $.each(data, function(i, item) { 
    console.log(item); 
    tbody.append(addRow1(item, fields)); 
    }); 
} 

function addRow1(item, fields) { 
    var row = '<tr>'; 
    $.each(fields, function(i, field) { 

    row +='<td>'+item[field]+'</td>'; 
    }); 
    row += '</tr>'; 
    return row; 
} 
});

您必须设置一个头

header("Access-Control-Allow-Origin: *"); 

在你的functions.php这就是你正在使用Ajax请求。
