Question

我已经调用了ajax api调用，我得到了json格式的响应。我想在屏幕上用html元素显示每个值。我已经实现了这一点，但是它无法根据需要创建动态设计。如果没有数据响应，我还要显示一条消息（“无可用数据”）。这是我的工作HTML和JSON示例。需要显示如下

Answer 1

如果我理解得很好，您想填写每个信息因此，使用javascript可以解析：

var parsedResponse = JSON.parse(ajaxesponse);
if(parsedResponse.length = 0){
   console.log('No data');
}else{
   var keys = Object.keys(parsedResponse[0]);
   //parsedResponse[0] for driver data
   for(var i = 0; i < keys.length ; i++){
      //The best thing to do is to change your class name and name it the same way as your keys in the response object
      $("."+keys[i]).html(parsedResponse[0][keys[i]]);
   }
}

和您的html：代替

<div>
   <label>Email:</label>
   <span class="demail"></span>
</div>

你有类似的东西

<div>
   <label>Email:</label>
   <span class="email"></span>
</div>

要使其动态化，您可以按照以下步骤操作

1。像这样为驱动程序分配值

$('.dname').html(driver_data[0].employeename);

2。像这样为乘客分配值

$('.pname').html(driver_data[0].passenger_data[0].employeename);

3。遍历您的结果（应该是第一个）

for (i = 0; i < result.length; i++) { 
// your assignments here
}

在这里，我已经在此 fiddle

中解析并附加了值

这是追加后的样子

[！[在此处输入图片描述] [2]] [2]

注意：

我为驾驶员和乘客添加了一些字段，您应该对其进行遍历并使其符合您的意愿。
您不需要创建静态HTML，而是可以从jquery本身执行此操作。这样您可以减少代码量。

更新：

OP希望如何遍历结果并修复其中的数据。

这里是updated fiddle，可以动态迭代

这是它的样子

[！[输出] [4]] [4]

$(document).ready(function() {
    $.get("http://www.mocky.io/v2/5ba349e82f000054009685b0", function(data, status) {
        var output = '';
        for (i = 0; i < data.length; i++) {
            var driverHtml = '<div class="col-md-4 driver"><div><label class="header">Driver Details</label></div><div><label>Name:</label><span class="dname">' + data[i].employeename + '</span></div>';
            var passengerHtml = '<div class="col-md-8 passenger"><div><label class="header">Passenger Details</label></div><div><label>Name:</label><span class="pname">' + data[i].passenger_data[0].employeename + '</span></div><hr>';
            output += driverHtml + passengerHtml;
        }
        $('#container').html(output);
    });
});

更新说明：

我已使用Mocky作为数据来模拟real time output like this

我还动态创建了HTML，仅填写了几个字段。您也可以填写其余字段。

希望这对您有所帮助。

有几种方法可以在HTML中填充JSON数据，即Ajax，getJSON，Fetch，JavaScript（纯），XMLHttpRequest。

这是下面使用fetch（）方法的示例。您可以根据自己的需要对其进行修改：

<div>
    <table>
        <tbody id="my-list">
            <tr>
                <th>Field 01</th>
                <th>Field 02</th>
                <th>Field 03</th>
                <th>Field 04</th>
                <th>Field 05</th>
            </tr>
        </tbody>
    </table>
</div>


<script>

$(function () {
    const url = 'https://jsonplaceholder.typicode.com/todos';
    fetch(url, { /* other parameters */ })
        .then(resp => resp.json())
        .then(data => { // Your code for handling the data you get from the API
            renderData(data);
        })
        .catch(function (error) { // This is where you run code if the server returns any errors
            console.log('There has been a problem with your fetch operation: ', error.message);
        });
});


function renderList(data) {
    var list = "";
    $.each(data, function (index) {
        href = "https://jsonplaceholder.typicode.com/todos?id=" + data[index].Id;
        list += "<tr>";
        list += "<td>" + data[index].Field01 + "</td>";
        list += "<td>" + data[index].Field02 + "</td>";
        list += "<td>" + data[index].Field03 + "</td>";
        list += "<td>" + data[index].Field04 + "</td>";
        list += "<td>" + data[index].Field05 + "</td>";
        list += "</tr>";
    })
    $("#my-list").append(list);
}

</script>
