为什么这只为标题和框内打印一个字符。我如何确保打印出来?
<!DOCTYPE html>
<html>
<head>
<!-- 1 -->
<link href="dropzone.css" type="text/css" rel="stylesheet" />
<!-- 2 -->
<script src="dropzone.min.js"></script>>
</head>
<script type="text/javascript">
//NOTHING WORKS IN HERE
// The camelized version of the ID of the form element
Dropzone.options.myAwesomeDropzone = {
maxFilesize: 1, // Size in MB
addRemoveLinks: true,
removedfile: function(file) {
var fileRef;
return (fileRef = file.previewElement) != null ?
fileRef.parentNode.removeChild(file.previewElement) : void 0;
}
};
</script>
<body>
<!-- 3 -->
<form action="upload.php" class="dropzone"></form>
</body>
</html>
只有&#39;我&#39;得到印刷,只有&#39; t&#39;为标题打印,问题是什么?
答案 0 :(得分:2)
如果你测试
ctypes.windll.user32.MessageBoxW(0, "info", "title", 3)
应该有&#34; info&#34;和&#34;标题&#34;。如果你测试
ctypes.windll.user32.MessageBoxA(0, "info".encode('ascii'),
"title".encode('ascii'), 3)
所以它似乎是某种文本编码问题。 UTF-16-le编码的字符串可能默认传递。
>>> 'info'.encode('utf-16-le')
b'i\x00n\x00f\x00o\x00'
>>> 'title'.encode('utf-16-le')
b't\x00i\x00t\x00l\x00e\x00'
由于MessageBoxA
期望NULL
终止C字符串,所以从头开始只考虑两个字符,即'i\0'
和't\0'
。
