我目前正在开发一个项目,根据点击的链接,以模式显示有关电影的一些信息(从omdbapi.com中提取)。以前这一切都是在后端使用PHP完成的,并且没有任何问题,但是由于页面上可以有5-100个电影链接,因此创建所有模式会导致页面需要一段时间才能加载。
现在我想用JS将模态创建/弹出窗口移到前面,这样只有在点击特定的电影链接时才会创建它。移动它使用Javascript我遇到了两个我无法解决的问题。
必须单击两次电影标题链接才能显示模式,我不确定导致这种情况的原因。查看开发工具,我可以看到在第一次单击时创建了一个模态,但由于某种原因没有显示。在第二次单击时,将创建并显示另一个。
一旦显示模态,我无法通过“X”按钮关闭它。我在PHP "<button type=\"button\" class=\"close exit-button\" data-dismiss=\"modal\">×</button>"
中使用的代码
不再有效。 Bootstrap可以使用$("#movieInfo").modal("hide")
显示/隐藏模态,但是如果我创建了一个函数来在单击按钮时运行它,它仍然不会隐藏。
这是我正在使用的JS代码:
window.addEventListener("load", function() {
var movielink = document.getElementById("movie");
movielink.addEventListener("click", function(){generateModal(this.innerHTML);}, false);
}, false);
function generateModal(movieT) {
var movieTitle = encodeURIComponent(movieT).replace(/%20/g, '+');
var url = "https://www.omdbapi.com/?t="+movieTitle+"&y=&plot=short";
$.getJSON(url, function(json) {
$('#modalContainer').html("<div id = \"movieInfo\" class = \"modal fade\" role = \"dialog\">"
+ "<div class \"modal-dialog modal-sm\">"
+ "<div class = \"modal-content\">"
+ "<div class = \"modal-body\">"
+ "<div class = \"poster\">"
+ "<img src = "+json.Poster+" width = 200 height = 300>"
+ "</div>"
+ "<div class = \"movie-specs\">"
+ "<button id = \"closebtn\" type=\"button\" class=\"close exit-button\"s onclick = \"closeModal()\">×</button>"
+ "<h3 class = \"movie-title\">"+json.Title+" ("+json.Year+")</h3>"
+ "<p class = \"topmargin-gone\">"+json.Rated+" | "+json.Runtime+" | "+json.Genre+"</p>"
+ "<p class = \"topmargin-gone\">"+json.Released+"</p><hr>"
+ "<div class = \"ratingInfo\">"
+ "<h4 class = \"topmargin-gone\"><strong>Ratings</strong></h4><p class = \"topmargin-gone\">Rated: "+json.imdbRating+"/10 "
+ "from "+json.imdbVotes+" users | Metascore: "+json.Metascore+"</p>"
+ "</div><hr>"
+ "<div class = \"plot-actors\">"
+ "<p>"+json.Plot+"</p><p><strong>Director: </strong>"+json.Director+"</p>"
+ "<p><strong>Writers: </strong>"+json.Writer+"</p>"
+ "<p><strong>Actors: </strong>"+json.Actors+"</p>"
+ "</div>"
+ "</div>"
+ "</div>"
+ "</div>"
+ "</div>"
+ "</div>");
});
$("#movieInfo").modal("show");
}
这是在PHP循环中创建链接的方式:
$allDisplay .= "<li><em><a id ='movie' href = '#'>"
. "$title[$z]</a></em> - $nominees[$z]</li>";
最后,这就是HTML如何查看链接和模态所在的位置:
<html>
<head>
<meta charset = "utf-8">
<title>Award Search</title>
<!-- jQuery Library -->
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<!--Bootstrap CSS -->
<link rel = "stylesheet" href = "https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<!-- Styles CSS sheet -->
<link rel = "stylesheet" href = "/src/styles/styles_awardQuery.css">
<!--Bootstrap JavaScript -->
<script src = "https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<script src = "/src/php/modalCreation.js"></script>
</head>
<body>
<div class = "site-wrapper">
<div class = "site-wrapper-inner">
<div class = "cover-container">
<div class = "masthead clearfix">
<div class = "inner">
<h3 class = "masthead-brand">Award Search</h3>
<ul class = "nav masthead-nav">
<li><a href = "/src/pages/welcomePage.php">Home</a></li>
<li><a href = "/src/pages/aboutLoggedIn.html">About</a></li>
<li><a href = "/src/pages/logoutPage.php">Logout</a></li>
</ul>
</div>
</div>
<div class = "inner cover">
<h1 class = "cover-heading">Academy Award Show Number <?php echo $academyNumber; ?>
<?php echo "($year[1])<br><span class = \"small\">Hosted by $acHost</span>"; ?></h1>
<?php echo $allDisplay; ?>
<div id ="modalContainer"></div>
</div>
</div>
</div>
</div>
</body>
</html>
我意识到这看起来很乱,但只是想让它现在正常运作。如果有人对任何一个问题有任何见解,那将非常感激。
感谢。
答案 0 :(得分:0)
在 bloc实际附加到您的网页之前,$("#movieInfo").modal("show");
被触发。这是由于网络延迟和AJAX调用的异步行为,允许您的脚本继续而无需等待获得答案。
为避免这种情况,您应将此行放在网络回调的末尾:
function generateModal(movieT) {
var movieTitle = encodeURIComponent(movieT).replace(/%20/g, '+');
var url = "https://www.omdbapi.com/?t="+movieTitle+"&y=&plot=short";
$.getJSON(url, function(json) {
$('#modalContainer').html('<div id="movieInfo" class="modal fade" role="dialog">'
+ '<div class "modal-dialog modal-sm">'
+ '<div class="modal-content">'
+ '<div class="modal-body">'
+ '<div class="poster">'+'<img src='+json.Poster+' width=200 height=300>'+'</div>'
+ '<div class="movie-specs">'
+ '<button id="closebtn" type="button" class="close exit-button"s onclick="closeModal()">×</button>'
+ '<h3 class="movie-title">'+json.Title+' ('+json.Year+')</h3>'
+ '<p class="topmargin-gone">'+json.Rated+' | '+json.Runtime+' | '+json.Genre+'</p>'
+ '<p class="topmargin-gone">'+json.Released+'</p><hr>'
+ '<div class="ratingInfo">'
+ '<h4 class="topmargin-gone"><strong>Ratings</strong></h4><p class="topmargin-gone">Rated: '+json.imdbRating+'/10 '
+ 'from '+json.imdbVotes+' users | Metascore: '+json.Metascore+'</p>'
+ '</div><hr>'
+ '<div class="plot-actors">'
+ '<p>'+json.Plot+'</p><p><strong>Director: </strong>'+json.Director+'</p>'
+ '<p><strong>Writers: </strong>'+json.Writer+'</p>'
+ '<p><strong>Actors: </strong>'+json.Actors+'</p>'
+ '</div>'+'</div>'+'</div>'+'</div>'+'</div>'+'</div>');
// after we have made the modal, we show it
$("#movieInfo").modal("show");
});
// code here will be fired before the end of the AJAX call
}
对于你的另一个错误,我认为双模式可以解释这个行为,所以先修补它,并告诉我们你是否仍然无法关闭你的模态;)
