I need to save a graph to a JSON file. Before doing that, I wrote a very simple HTML/JavaScript to test it out (just use a simple string for the JSON).
Based on the suggestion in a Stack Overflow posting, I use saveAs() method. But it looks like saveAs() does not work and no file is created. I am using Internet Explorer and Window 10.
In order to debug it, I inserted 3 window.alert() calls. The first 2 window.alert() calls pop up correctly, however, the 3rd window.alert() call does not show up at all. So I am afraid that the code is aborted at the saveAs() call.
The following is my code:
<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? Am I missing something here? Do I need to add something to my computer in order to use saveAs() method?
Thank you very much for your advice!

You are a little bit error in saveAs. Code is given below:
<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");
var link=window.URL.createObjectURL(jsonBlob);
window.location=link;
window.alert("I am here 3");
}
</script>
</head>
<body>
<form name="myform">
<input type="button" onClick="save();" value="Save">
</form>
</body>
</html>
Also you can see this:
Convert into excel sheet using JavaScript
var excelBlob = new Blob([response], { type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" }, "excel.xlsx");
var link=window.URL.createObjectURL(excelBlob);
window.location=link;
