Menu
On button click, I'm using window.print() of javascript for printing print_div contents,
But because of some security issue, i wanted to avoid the multiple printing (like using Cntrl + P) options, So i was thinking of to clear print_div contents, that users can't re-print again and again.
Rough Code here,
document.getElementById("print_div").innerHTML = //Some contents to be printed on paper.
window.print()
document.getElementById("print_div").innerHTML = '' // Clearing old contents to avoid mis-use
But this code not working at all, its clearing print_div contents before creating print preview like in chrome.(i guessed, working Asynchronously)
Could any one tell me, where am doing wrong here?
Note: Am using Chrome: 22.0.1229.92 m to test my code & i want to go for chrome only.

It's because print window wasn't loaded.
var showPrintWindow = function (context) {
var printWindow = window.open('', '');
var doc = printWindow.document;
doc.write("<html><head>");
doc.write("<link href='/css/printReport.css' rel='stylesheet' type='text/css' media='print' />");
doc.write("</head><body>");
doc.write(context);
doc.write("</body></html>");
doc.close();
function show() {
if (doc.readyState === "complete") {
printWindow.focus();
printWindow.print();
printWindow.close();
} else {
setTimeout(show, 100);
}
};
show();
};
You can use setTimeout method and try it.
setTimeout("your code or function etc",mili seconds)
setTimeout("document.getElementById('print_div').innerHTML = ''",5000);
