and put the results into 3 different div. I'm watching this code Best way to display data via JSON using jQuery changing the json link and linking the external resource of jquery but i can't find where is the problem. thanks
这是我的实际代码:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js" type="text/javascript" charset="utf-8"></script>
<script type="text/javascript">
$(document).ready(function(){
$.getJSON("./reservations.json",function(data){
$.each(data, function(i,post){
content += '<h3>' + error_message + '</h3>';
$(content).appendTo("#error_message");
});
});
});
</script>
</head>
<body>
<div class="container">
<div id="error_message"></div>
<div id="reservations"></div>
<div id="error_code"></div>
</div>
</body>
</html>
推荐答案
content += '<h3>' + error_message + '</h3>';
在任何地方都没有定义content
或error_message
,因此该行将不起作用.
Neither content
nor error_message
is defined anywhere, so this line won't work.
尝试使用:
var content = '<h3>' + post.error_message + '</h3>';
此外,如果JSON与问题中显示的完全一样,则不需要$.each
.
Also, if the JSON is exactly like shown in the question, you don't need $.each
.
var content = '<h3>' + data.error_message + '</h3>';
$(content).appendTo("#error_message");
