JavaScript停止运行,没有错误消息
作者：互联网
使用Uploadify和JGrowl组合：
<link rel="stylesheet" type="text/css" href="css/default.css" /><link rel="stylesheet" type="text/css" href="css/jgrowl.css" />
<script type="text/javascript" src="js/jquery1.4.4.js"></script>
<script type="text/javascript" src="js/jgrowl.js"></script>
<link rel="stylesheet" type="text/css" href="css/artworkDesigner.css" />
<link href="js/uploadify-2.1.4/uploadify.css" type="text/css" rel="stylesheet" />
<script type="text/javascript" src="js/uploadify-2.1.4/jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="js/uploadify-2.1.4/swfobject.js"></script>
<script type="text/javascript" src="js/uploadify-2.1.4/jquery.uploadify.v2.1.4.min.js">/script>
<script type="text/javascript">
// <![CDATA[
var uploadType = "art";
var templateID = "42scs";
$(document).ready(function() {
$('#fileInput').uploadify({
'uploader': 'js/uploadify-2.1.4/uploadify.swf',
'script': 'js/uploadify-2.1.4/UploadHandler.ashx',
'cancelImg': 'js/uploadify-2.1.4/cancel.png',
'scriptData': { 'type': uploadType, 'templateID': templateID },
'auto': true,
'multi': true,
'fileDesc': 'Image Files',
'fileExt': '*.jpg;*.png;*.gif;*.bmp;*.jpeg',
'queueSizeLimit': 90,
'sizeLimit': 4000000,
'buttonText': 'Choose Images',
'folder': '/uploads/test',
'onComplete': function(event, ID, fileObj, response, data) {
if (response != "1") {
alert(response); // ALERTS 'ERROR TEXT' which is expected
// DOESNT RUN THIS LINE:, AND REST OF SCRIPT SEEMS TO FREEZE
$.jGrowl("<strong>Error!</strong><br />" + response, { sticky: true });
alert("flag"); // THIS IS NOT RUNNING
} else {
alert(fileObj.name + "\n" + fileObj.filePath + "\n" + ID + "\n");
alert(response);
}
}
});
});
// ]]></script>
当templateID设置为实数(末尾没有字符串以有意引发错误)时,此脚本可以正常工作,但是如上代码所示,在42scs中传递了无效字符串时,该脚本将发出警报
“Some error text”
当服务器端抛出异常时,这是正确的返回值.然后,在打算引发Jgrowl错误时,脚本将停止执行任何其他操作.有什么想法为什么没有发生？
我在另一页上完全相同地使用Jgrowl,并且工作正常.
解决方法:
对Jquery库的双重引用将发生冲突：
<script type="text/javascript" src="js/jquery1.4.4.js"></script>
<script type="text/javascript" src="js/uploadify-2.1.4/jquery-1.4.2.min.js"></script>
