Hello there
I found a solution:
<html>
<head>
<script>
sagecell.makeSagecell({
inputLocation: '#pyscript',
template: sagecell.templates.minimal,
});
</script>
<script src="sagesrc.js"></script>
</head>
<body onload="sagesrc()">
......
<div id="pyscript">
<script type="text/x-sage" src="somepgm.py"></script>
</div>
.......
</body>
</html>
The script:sagesrc.js:
function getPyScr(s) {
"use strict";
var xhr;
xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
s.innerHTML = this.responseText;
}
};
xhr.open("GET", s.src, false); //If async is true it does not work
xhr.send();
}
function sagesrc() {
"use strict";
var scrObj, scrObjLen, i;
scrObj = document.scripts;
scrObjLen = scrObj.length;
for (i = 0; i < scrObjLen; i++) {
if (scrObj[i].type === "text/x-sage" && scrObj[i].src != "") {
getPyScr(scrObj[i]);
}
}
}
If the Python script, as in my case, is large it will take some time to load
But I can write it once and use it several times and in different places
Obviously, any improvement and / or comment is welcome
