Question

我有这个json数据，我已经创建了两个数组并将其作为json回显。并希望通过匹配一个数组的id和另一个数组的userId，使用两个循环在html中显示它。

{"personaldetails":[{"id":"79","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"78","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"77","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"76","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"75","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"74","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"73","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"72","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"71","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"70","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"69","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"},{"id":"68","FirstName":"Elon","MiddleName":"","LastName":"Musk","Gender":"Male","Location":"New York","Email":"elonmusk@tesla.com","Mobile":"1234567890"}]}{"bookdetails":[{"UserId":"79","BookTitle":"who am i","BookGenre":"inspiration","BookWriter":"modi","BookDescription":"this book is all about the struggle one faces all his life.no matter what he does he never get any attention"},{"UserId":"79","BookTitle":"a walk to remember","BookGenre":"romance","BookWriter":"peter","BookDescription":"a wall in the rainy season where all "},{"UserId":"78","BookTitle":"who am i","BookGenre":"inspiration","BookWriter":"modi","BookDescription":"this book is all about the struggle one faces all his life.no matter what he does he never get any attention"},{"UserId":"78","BookTitle":"a walk to remember","BookGenre":"romance","BookWriter":"peter","BookDescription":"a wall in the rainy season where all "},{"UserId":"77","BookTitle":"who am i","BookGenre":"inspiration","BookWriter":"modi","BookDescription":"this book is all about the struggle one faces all his life.no matter what he does he never get any attention"},{"UserId":"77","BookTitle":"a walk to remember","BookGenre":"romance","BookWriter":"peter","BookDescription":"a wall in the rainy season where all "},{"UserId":"76","BookTitle":"who am i","BookGenre":"inspiration","BookWriter":"modi","BookDescription":"this book is all about the struggle one faces all his life.no matter what he does he never get any attention"},{"UserId":"76","BookTitle":"a walk to remember","BookGenre":"romance","BookWriter":"peter","BookDescription":"a wall in the rainy season where all "},{"UserId":"75","BookTitle":"who am i","BookGenre":"inspiration","BookWriter":"modi","BookDescription":"this book is all about the struggle one faces all his life.no matter what he does he never get any attention"},{"UserId":"75","BookTitle":"a walk to remember","BookGenre":"romance","BookWriter":"peter","BookDescription":"a wall in the rainy season where all "},{"UserId":"74","BookTitle":"who am i","BookGenre":"inspiration","BookWriter":"modi","BookDescription":"this book is all about the struggle one faces all his life.no matter what he does he never get any attention"},{"UserId":"74","BookTitle":"a walk to remember","BookGenre":"romance","BookWriter":"peter","BookDescription":"a wall in the rainy season where all "},{"UserId":"73","BookTitle":"who am i","BookGenre":"inspiration","BookWriter":"modi","BookDescription":"this book is all about the struggle one faces all his life.no matter what he does he never get any attention"},{"UserId":"73","BookTitle":"a walk

但是我没有通过console.log或javascript警告在html中获取这些数据。

这是代码;

function loadData(){
    var url = "http://localhost/ReadExchange/api.php";
    $.getJSON(url,function(data) {
        console.log(data);
        alert("hey got the data"+JSON.stringify(data));
    });
}

$(function() {
    loadData();
});

这是我的api代码;

 $personal = $db->prepare('select Id,FirstName,MiddleName,LastName,Gender,Location,Email,Mobile from personaldetails ORDER BY Id DESC');
$personal->execute();
$json_data=array();



foreach($personal as $row)//foreach loop  
{  

    $json_array['id']=$row['Id'];  
    $json_array['FirstName']=$row['FirstName'];  
    $json_array['MiddleName']=$row['MiddleName'];  
    $json_array['LastName']=$row['LastName']; 
    $json_array['Gender']=$row['Gender']; 
    $json_array['Location']=$row['Location']; 
    $json_array['Email']=$row['Email']; 
    $json_array['Mobile']=$row['Mobile'];
    array_push($json_data,$json_array);

}

$books = $db->prepare('select UserId,BookTitle,BookGenre,BookWriter,BookDescription from bookdetails ORDER BY UserId Desc'); 
    $books->execute();
    $json_data1=array();

     //$bookNo = 0;
    foreach($books as $row)//foreach loop  
    {  
        //$bookNo++;
        //$json_array1['BookNo']= $bookNo;  
        $json_array1['UserId']=$row['UserId']; 
        $json_array1['BookTitle']=$row['BookTitle']; 
        $json_array1['BookGenre']=$row['BookGenre'];  
        $json_array1['BookWriter']=$row['BookWriter']; 
        $json_array1['BookDescription']=$row['BookDescription']; 

    //here pushing the values in to an array  
    array_push($json_data1,$json_array1);  

}  header('Content-type: application/json');
    echo json_encode(array("personaldetails"=>$json_data));
    echo json_encode(array("bookdetails"=>$json_data1));
    //echo json_encode($json_data1);  

?>

提前感谢！

您必须只发送一个JSON对象，所以不要：

 echo json_encode(array("personaldetails"=>$json_data));
    echo json_encode(array("bookdetails"=>$json_data1));

可是：

 echo json_encode(array(
       "personaldetails"=>$json_data,
       "bookdetails"=>$json_data1 
));

无法在html中显示json数据
