#1

This is chrome extension js file. Pressing ctrl + c copies the selected object. I want work on chrome right click menu, not with ctrl + c

var linkAddress = $(’’);
$(‘body’).append(linkAddress);
// This is a DOM element that has to be selectable but not visible to
anybody
linkAddress.css({position: ‘absolute’, left:’-9999em’});

var previousCaretPosition = -1;

COPYL_DEBUG = false;

function write_to_console(text) {
if (COPYL_DEBUG)
console.log(text);
}

function selectElement(el) {
// Check if anything is currently selected, if so backup
if (window.getSelection().rangeCount > 0) {
previousCaretPosition = document.activeElement.selectionStart;
}
write_to_console("Previous cursor position: " + previousCaretPosition);
var range = document.createRange();

write_to_console("Selecting element " + el);
write_to_console("el[0] is " + el[0]);
range.selectNodeContents(el[0]);
write_to_console("Range: " + range);

write_to_console("Window selection range count before: " +
window.getSelection().rangeCount);
if (window.getSelection().rangeCount > 0) {
window.getSelection().removeAllRanges();
}
write_to_console("Window selection range count now: " +
window.getSelection().rangeCount);

write_to_console("Active Element: " + document.activeElement);
window.getSelection().addRange(range);
write_to_console("Window selection range count after: " +
window.getSelection().rangeCount);
}

function clearLinkAddress() {
if (linkAddress.text()) {
linkAddress.text("");
linkAddress.blur();
write_to_console(“Cleared linkAddress”);

write_to_console("window.getSelection: " + window.getSelection());
window.getSelection().removeAllRanges();

}
if (previousCaretPosition != -1)
{
document.activeElement.selectionStart = previousCaretPosition;
write_to_console("Previous cursor position set: " +
document.activeElement.selectionStart);
}

write_to_console("Current selection: " + window.getSelection().toString());
}

$(function() {
// The code attaches itself to all anchor elements
$(“html”).on(“mouseenter”, “td”, function(){
// Everytime the user hovers (enters) a link
if(window.getSelection().toString()) {
write_to_console(“Something is already selected. Don’t do
anything.”);
} else {
write_to_console(“Nothing is selected.”);

    linkAddress.text($(this).prop('title'));
    write_to_console("linkAddress: " + linkAddress.text());
    selectElement(linkAddress);
}

write_to_console("Current Selection: " + 

window.getSelection().toString());
}).on(“mouseleave”, “td”, function(){
// Every time the user leaves a link
write_to_console(“Leaving link.”);
clearLinkAddress();
});

$(window).on(“beforeunload”, function() {
clearLinkAddress();
});

});
