I want to create a in-window popup when some text is highlighted, similar to how the Google Dictionary extension works. I've already figured out how to do the highlighting portion, just can't figure out how to create the popup.
Here's the code for the highlighting:
function getSelectionText() {
var text = "";
if (window.getSelection) {
text = window.getSelection().toString();
} else if (document.selection && document.selection.type != "Control") {
text = document.selection.createRange().text;
}
console.log(text);
}
document.onmouseup = function() {getSelectionText()};
