Question

我试图将这个项目从Udacity介绍到AJAX。

我将Google街景图片显示在后台，但在我尝试使用jQuery.getJSON()方法添加“纽约时报”文章之后，所有功能都会失败并失去我所做的一切。

图像消失了，所有脚本都运行不正常。

任何人都可以帮我解决这个问题吗？

＆＃13;

function loadData() {

    var $body = $('body');
    var $wikiElem = $('#wikipedia-links');
    var $nytHeaderElem = $('#nytimes-header');
    var $nytElem = $('#nytimes-articles');
    var $greeting = $('#greeting');

    // clear out old data before new request
    $wikiElem.text("");
    $nytElem.text("");

    // load streetview
	var streetStr =$('#street').val();
	var cityStr = $('#city').val();
	var address = streetStr + ',' + cityStr;
	var mapUrl = 'http://maps.googleapis.com/maps/api/streetview?size=600x300&location=' + address + ' ';
	$greeting.text('So, you want to live at' +' ' + address +  '?');
	$body.append('<img class="bgimg" src="' + mapUrl + '">');

	//NYT articles and headline
var nytUrl = 'https://api.nytimes.com/svc/search/v2/articlesearch.json?q=' + cityStr + '&sort=newest&api-key=f704d0319c734128a3f7f681e32f2556';
	
	$.getJSON(nytUrl, function(data){
		$nytHeaderElem.text('New York Times Article about' +' ' + cityStr);
		
		var articles =data.response.docs;
		for (var i = 0; i < articles.length; i++){
			var article = articles[i];
			$nytElem.append('<li class="articles">' + '<a href="' + article.web_url+ '">' + article.headline.main + '</a>' +
						'<p>' + article.snippet + '</p>' + '</li>');
		};
	})
	
	
    // YOUR CODE GOES HERE!

    return false;
};

$('#form-container').submit(loadData);

＆＃13;

.bgimg {
    position:fixed;
    top: 0;
    left: 0;
    width:100%;
    z-index:-1;
    opacity:1;
}

Answer 1

我猜它不起作用，因为你（分别是示例中的bootstrap）正在使用jQuery的“slim”变体（https://code.jquery.com/jquery-3.2.1.slim.min.js）。

getJson不在此变体中。

使用“常规”最小化变体： http://code.jquery.com/

jQuery.getJSON函数在Bootstrap上不起作用
