I want to print some content from a vue component. For example from the following snippet, I would like to print the v-card-text element which also has an id of #print:
new Vue({
el: '#app',
data() {
return {
dialog: false
}
},
methods: {
print() {
var prtContent = document.getElementById("print");
var WinPrint = window.open('', '', 'left=0,top=0,width=800,height=900,toolbar=0,scrollbars=0,status=0');
WinPrint.document.write(prtContent.innerHTML);
WinPrint.document.close();
WinPrint.focus();
WinPrint.print();
WinPrint.close();
}
}
})<!doctype html>

</html>However,when I get prompted for the print, all the styles associated with it goes away. How can I print a vue component in such a way so that the components won't lose the associated styles? I recommend to copy the snippet to your local machine for the best effect.
You need to copy over the styles from the original document. Try something like this:
// Get HTML to print from element
const prtHtml = document.getElementById('print').innerHTML;
// Get all stylesheets HTML
let stylesHtml = '';
for (const node of [...document.querySelectorAll('link[rel="stylesheet"], style')]) {
stylesHtml += node.outerHTML;
}
// Open the print window
const WinPrint = window.open('', '', 'left=0,top=0,width=800,height=900,toolbar=0,scrollbars=0,status=0');
WinPrint.document.write(`<!DOCTYPE html>
<html>
<head>
${stylesHtml}
</head>
<body>
${prtHtml}
</body>
</html>`);
WinPrint.document.close();
WinPrint.focus();
WinPrint.print();
WinPrint.close();
