Here's a scenario where a div appears if text is selected that is not just a space, but remains visible even after the selection is removed. Is there a way to hide the div if the selection becomes empty?
$("#actual_verse").mouseup(function() {
var text = "";
if (window.getSelection) {
text = window.getSelection().toString();
} else if (document.selection && document.selection.type != "Control") {
text = document.selection.createRange().text;
}
if (/\S/.test(text)) {
// Tool Tip
var ele = document.getElementById('tooltip');
var sel = window.getSelection();
var rel1 = document.createRange();
rel1.selectNode(document.getElementById('cal1'));
var rel2 = document.createRange();
rel2.selectNode(document.getElementById('cal2'));
if (!sel.isCollapsed) {
var r = sel.getRangeAt(0).getBoundingClientRect();
var rb1 = rel1.getBoundingClientRect();
var rb2 = rel2.getBoundingClientRect();
//this will place ele below the selection
ele.style.top = (r.bottom - rb2.top) * 100 / (rb1.top - rb2.top) + 'px';
//this will align the right edges together
ele.style.left = (r.left - rb2.left) * 100 / (rb1.left - rb2.left) + 'px';
//code to set content
ele.style.display = 'block';
}
// End of Tool Tip
}
