I am looking to export HTML text as a word document with A4 size and portrait orientation. My JavaScript currently allows me to export the text, but it appears like a webpage format rather than in A4 or portrait mode. I have tried adding @page CSS styling to achieve this, but so far it has not been successful. Can someone advise on how I should modify my CSS or JavaScript to accomplish this task? Here is the link to my script.
function Export2Doc(element, filename = ''){
var preHtml = "<html xmlns:o='urn:schemas-microsoft-com:office:office' xmlns:w='urn:schemas-microsoft-com:office:word' xmlns='http://www.w3.org/TR/REC-html40'><head><meta charset='utf-8'><title>Export HTML To Doc</title></head><body>";
var postHtml = "</body></html>";
var html = preHtml+document.getElementById(element).innerHTML+postHtml;
var blob = new Blob(['\ufeff', html], {
type: 'application/msword'
});
// Specify link url
var url = 'data:application/vnd.ms-word;charset=utf-8,' + encodeURIComponent(html);
// Specify file name
filename = filename?filename+'.doc':'document.doc';
// Create download link element
var downloadLink = document.createElement("a");
document.body.appendChild(downloadLink);
if(navigator.msSaveOrOpenBlob ){
navigator.msSaveOrOpenBlob(blob, filename);
}else{
// Create a link to the file
downloadLink.href = url;
// Setting the file name
downloadLink.download = filename;
//triggering the function
downloadLink.click();
}
document.body.removeChild(downloadLink);
} @page
{
size:21cm 29.7cmt; /* A4 */
margin:1cm 1cm 1cm 1cm; /* Margins: 2.5 cm on each side */
mso-page-orientation: portrait;
}
@page Section1 { }
div.Section1 { page:Section1; }<div id="exportContent">
<div class=Section1>
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged.
