display alert when mouse hovers over word in text
- by user1672790
I have been struggling with this for a few days. I need somebody to steer me in the right direction. I have been searching on the web. I am not sure if I took the right approach. What I need is that each time a person hovers over a particular keyword, it should display an alert box. In this example the word is else. When I run the code it does not give any errors and does not display anything when mouse hovers on the word.
function on_func2()
{
var searchString = 'else';
var elements = document.getElementById('paragraph2');
for (var i = 0; i < elements.length; i++)
{
if (elements[i].innerHTML.indexOf(searchString) !== -1)
{
alert('Match');
break;
}
}
}
