Hi,
I am in multi tenant cloud environment.
And I am trying to find a way for calling Javascript function directly from FromScript.
I have defined User Control Component with this code:
<!DOCTYPE html>
<html>
<head>
<!-- Must set compatibility to IE9 or greater -->
<meta http-equiv="X-UA-Compatible" content="IE=9">
<!-- include the mongoose UserControl.js library -->
<!-- NOTE: MAKE SURE TO MAKE THE src PATH RELATIVE TO THIS FILE -->
<script type="text/javascript" src="../../$app/scripts/UserControl.js"></script>
<script src="https://code.jquery.com/jquery-3.6.4.js"></script>
<script type="text/javascript">
const DownloadFce = {
getVar: function (varName) {
return new Promise((resolve, reject) => {
WSForm.getVarValue(varName, function (value) {
console.log("Value in callback: " + value);
if (value) {
resolve(value);
} else {
reject("no value");
}
});
});
},
};
</script>
<style>
@import url ('https://fonts.googleapis.com/css2?family=Bebas+Neue&family=Koulen&family=Lato&family=Nunito&family=Playfair+Display:ital@1 &family=Prata&family=Raleway:ital,wght@1 ,100&family=Roboto&family=Roboto+Condensed&family=Teko&display=swap');
.btn {
font-family: Roboto, Arial, sans-serif;
font-weight: 700;
font-size: 13px;
line-height: 1;
color: #ffffff;
background-color: #1976d2;
border: none;
border-radius: 10px;
min-width: 120px;

padding: 0 18px;
display: inline-flex;
align-items: center;
justify-content: center;
cursor: pointer;
}
</style>
</head>
<body style="font-family:Arial,Helvetica;font-size:12px">
<button class="btn" id="btDownload" onclick="DownloadClick()">Download</button>
<script>

}
}
return new Uint8Array(bytes);
}
async function DownloadClick() {
let filename = await DownloadFce.getVar("varFilename");
let fileContent = await DownloadFce.getVar("varFileContent");
const bytes = encodeWindows1250(fileContent);
const blob = new Blob([bytes], { type: 'text/plain;charset=windows-1250' });
if (window.navigator && window.navigator.msSaveOrOpenBlob) {
window.navigator.msSaveOrOpenBlob(blob, filename);
return;
}
const url = URL.createObjectURL(blob);
const element = document.createElement('a');
element.href = url;
element.download = filename;
element.style.display = 'none';
document.body.appendChild(element);
element.click();
document.body.removeChild(element);
URL.revokeObjectURL(url);
}
</script>
</body>
</html>
It is creating Download button, thru which user can download file. File content is passed from Form Variable. And also here is done converting to Windows-1250 code page.
But is it possible to call this DownloadClick function directly from FormScript?
On docs.infor.com I found this, and there is something about PostUserControlMessage, but it is not explained further:
