When the mouse is over the help icon, we want to display the help text, when the mouse is out, hide the help text.
To achieve this mouseover and mouseout events can be used as shown below.
$(document).ready(function () {
$('img[src="help.png"]').mouseover(function () {
$('#' + getDivId(this)).fadeIn(400);
$(this).css('cursor', 'pointer');
}).mouseout(function () {
$('#' + getDivId(this)).fadeOut(400);
});
function getDivId(helpIcon) {
var helpIconId = $(helpIcon).attr('id');
return helpIconId.replace('img', 'div');
}
});
$(document).ready(function () {
$('img[src="help.png"]').mouseenter(function () {
$('#' + getDivId(this)).fadeIn(400);
$(this).css('cursor', 'pointer');
}).mouseleave(function () {
$('#' + getDivId(this)).fadeOut(400);
});
function getDivId(helpIcon) {
var helpIconId = $(helpIcon).attr('id');
return helpIconId.replace('img', 'div');
}
});
We can also achieve the same using hover. hover() function accepts two function arguments, one for mouseenter event and one for mouseleave event.
$( selector ).hover( handlerIn, handlerOut )
is shorthand for
$( selector ).mouseenter( handlerIn ).mouseleave( handlerOut )
$(document).ready(function () {
$('img[src="help.png"]').hover(function () {
$('#' + getDivId(this)).fadeIn(400);
$(this).css('cursor', 'pointer');
}, function () {
$('#' + getDivId(this)).fadeOut(400);
});
function getDivId(helpIcon) {
var helpIconId = $(helpIcon).attr('id');
return helpIconId.replace('img', 'div');
}
});
