I have a refresh "button" (actually a png image) which the user can hover their mouse over, turning it from gray to blue. When refresh is clicked, the image changes to a play "button" which exhibits similar color-changing behavior, except when you click on the play image it should switch back to the original refresh image.
The problem is that, after clicking on the refresh image, when I click on the play image without removing my mouse from the image, it doesn't change back to the refresh image.
I have already looked into event propagation stopping.
Here is my code:
$('#refresh').click(function (event) {
if (!tMinusZero) {
$('#refresh').html("<img src='play_small_hover.png'>");
tMinusZero = true;
event.stopImmediatePropagation();
} else {
$('#refresh').html("<img src='refresh_small_hover.png'>");
tMinusZero = false;(
event.stopImmediatePropagation();
}
});
$('#refresh').hover(function () {
if (!tMinusZero) {
$('#refresh').html("<img src='refresh_small_hover.png'>");
} else {
$('#refresh').html("<img src='play_small_hover.png'>");
}
}, function () {
if (!tMinusZero) {
$('#refresh').html("<img src='refresh_small.png'>");
} else {
$('#refresh').html("<img src='play_small.png'>");
}
});
Some interesting things I have noticed whilst trying to debug:
It seems to me that my two event handlers have conflicting interests, but stopping the event propagation doesn't seem to help.
If I understand correctly how you want it to behave, your code seems to work just fine, even though there's a typo in the click event (round bracket).
tMinusZero = false;(
Also, just for improve the code you can replace
$('#refresh')
with
$(this)
inside the event as it'll refer to the dom element you attached the event to.
Why don't you try to tackle your problem with CSS, i think it will be more elegant, make a small DIV, with a background corresponding to your image, define a hover state and an active state, plus a small script to change between 2 more additional states
Something like: CSS:
#refresh[data-state=notclicked]
{
background-image:url('play_small.png');
cursor:pointer;
}
#refresh[data-state=notclicked]:hover
{
background-image:url('play_small_hover.png');
cursor:pointer;
}
#refresh[data-state=clicked]
{
background-image:url('refresh_small.png');
cursor:pointer;
}
#refresh[data-state=clicked]:hover
{
background-image:url('refresh_small_hover.png');
cursor:pointer;
}
Of course you will have to define the width and the height in the CSS, to a fixed width.height which matches your png size.
Than the js:
$("#refresh").click(function(){
if ($(this).attr('data-state')=='clicked') {$(this).attr('data-state','notclicked');}
else {$(this).attr('data-state','clicked');}
});
