I am trying to print data to a pre formatted document. Student will answer the questions in text area, when click on print to PDF I will print the answer with school name and logo. Everything working fine but logo is not previewing and printing. I collected the code. Simple HTML and JavaScript. Thanks in advance.
Here is the complete code
<html>
<head>
<title>Online Test</title>
</head>
<body>
<div style="padding: 10px 0;">
<h1>Online Test</h1>
</div>
<!--Data entry section.-->
<div id="container_data_entry">
<h2 id="subject"><b>Subject - Computer Science</b></h2> <br />
<div id="container" style="width:100%;overflow:auto;">
<ul>
<li><b>Q No. 1:</b>Question one?</li>
<li><textarea id="a1"></textarea></li>
</ul>
<ul>
<li><b>Q No. 2:</b>Question two?</li>
<li><textarea id="a2"></textarea></li>
</ul>
<ul>
<li><b>Q No. 3:</b> Question three?</li>
<li><textarea id="a3"></textarea></li>
</ul>
</div>
<div style="text-align:center;">
<input type="button" style="" value="Print to PDF" id="btPrint" onclick="onlineTestApp.printPage();" />
</div>
</div>
</body>
<script>
let onlineTestApp = new function () {
this.printPage = function () {
let style = "<style>";
style = style + "h1, h2 {text-align:center; font:22px Times New Roman; font-weight:bold;}";
style = style + ".answers {font:18px Calibri; padding:10px 0;}";
style = style + "</style>";
let header ='<img src="logo.png" width="100px" height="100px"/>' +
'<h1>School Name</h1>' + '<h2>Online Test</h2>';
let theBody = '';
// get all textarea (anwsers).
let ele_tArea = document.getElementsByTagName('textarea');
for (let i = 0; i <= ele_tArea.length - 1; i++) {
if (theBody === '') {
if (ele_tArea[i].value != '') {
theBody = '<p class="answers"> <b>Answer ' + (i + 1) + '</b> - ' + ele_tArea[i].value + '</p>';
}
}
else {
if (ele_tArea[i].value != '') {
theBody = theBody + '<p class="answers"> <b>Answer ' + (i + 1) + '</b> - ' + ele_tArea[i].value + '</p>';
}
}
}
theBody = header + theBody;
// Create window object and print the data.
let newWin = window.open('', '', '');
newWin.document.write(style);
newWin.document.write(theBody);
newWin.print();
newWin.close();
}
}
