[英]Why saveAs() in JavaScript does not work for me?
I need to save a graph to a JSON file. 我需要将图形保存到JSON文件。 Before doing that, I wrote a very simple HTML/JavaScript to test it out (just use a simple string for the JSON).
在此之前,我编写了一个非常简单的HTML / JavaScript对其进行测试(只需对JSON使用一个简单的字符串)。
Based on the suggestion in a Stack Overflow posting, I use saveAs() method. 根据Stack Overflow发布中的建议,我使用saveAs()方法。 But it looks like saveAs() does not work and no file is created.
但看起来saveAs()无法正常工作,也没有创建文件。 I am using Internet Explorer and Window 10.
我正在使用Internet Explorer和Window 10。
In order to debug it, I inserted 3 window.alert() calls. 为了调试它,我插入了3个window.alert()调用。 The first 2 window.alert() calls pop up correctly, however, the 3rd window.alert() call does not show up at all.
前两个window.alert()调用正确弹出,但是第三个window.alert()调用根本不显示。 So I am afraid that the code is aborted at the saveAs() call.
因此,恐怕代码在saveAs()调用中止。
The following is my code: 以下是我的代码:
<html>
<head>
<title>Save</title>
<script>
function save()
{
window.alert("I am here 1");
var jsonBlob = new Blob([JSON.stringify("kiki")], { type: 'application/javascript;charset=utf-8' });
window.alert("I am here 2");
saveAs(jsonBlob, "testout.json");
window.alert("I am here 3");
}
</script>
</head>
<body>
<form name="myform">
<input type="button" onClick="save();" value="Save">
</form>
</body>
</html>
I am wondering why saveAs() does not work for me? 我想知道为什么saveAs()对我不起作用? Am I missing something here?
我在这里想念什么吗? Do I need to add something to my computer in order to use saveAs() method?
我是否需要在计算机上添加某些内容才能使用saveAs()方法?
Thank you very much for your advice! 非常感谢您的建议!
