无法在html页面中显示JSON数据

标签: javascript jquery html json

我正在使用Foursquare API开发API应用程序。使用我的 getRequest , 我的结果是 JSON ,我在控制台 .log中显示。

问题是,我不知道如何解析 JSON数据并在 HTML网页上显示我想要的内容。

我正在尝试显示场地的'name',但我不知道该怎么做。

PS:我对来自Foursquare的传入数据有一个 Math.random 函数,所以我在console.log中显示的随机地点名称就是我想要的显示在我的HTML页面中。

HTML:

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Search</title>
<link href='http://fonts.googleapis.com/css?family=Lobster' rel='stylesheet' type='text/css'>

<script type="text/javascript" src="apps/app.js"></script>

</head>

    <body>

        <H1>Hunger Pains</H1>
            <p>Search for food cause you cant take it anymore</p>

            <!--This is the area your location gets spit out on the html page-->
            <p id="demo"></p>

            <form id ="search-term">

            <!--text entry field-
            <input type="text" id="query">-->

            <!--Submit button-->
            <input id="submit" type="submit"  value="submit">

            <!--Search results div-->
            <div id="search-results"></div>


            </form>
    </body>
</html>

Jquery的:

$(document).ready(function(){

//document.getElementById("submit").disabled = false;

//When you click the submit button it fires off the getRequest.
$(function(){
  $('#search-term').submit(function(event){
     event.preventDefault();
     //getRequest();
        myFunction();


  });
});

// This is the get request. It has a random function that randomizes the callback data. Once you get the randomizes data, it shows in the console window.
//This function displays three random results based on the myFunction below
function getRequest(){

  $.getJSON('https://api.foursquare.com/v2/venues/search?v=20131016&ll=40.7%2C-74&intent=browse&radius=800&categoryId=4d4b7105d754a06374d81259&client_id=C2IEUINHBL2HEVOHIWNO0GGN5EUHK3PGYH03HCZRP2ETA4CF&client_secret=DOLF3UBQZOY5GX2DP3EXBQ5CW4AHEWMNDGRMH0IHJWZBDSIO', function(data){
    var random = data.response.venues[Math.floor(Math.random() * data.response.venues.length)];
    //showResults();
    console.log(random);

    });

}

//This is the function that calls getRequest function three times then stops.

  function myFunction(){
    var myVar = setInterval(function(){getRequest();}, 500);
    //clearTimeout(myVar);
    setTimeout(function( ) { clearInterval( myVar); }, 1600);
}

});

这样的事情应该这样做:

$("#search-results").append('<br>' + random.name);

要从Foursquare获取的对象中获取名称,请使用:

console.log(random.name);

如果你需要网址,例如使用:

console.log(random.url);
