How to set jQuery UI toggle programmatically?
I noticed it is possible to set the value of a jQuery UI slider in the following way:
$("#mySlider").slider("value", 42);
This triggers the event handlers attached to the slider as expected.
Now I'm trying to do the same trick using a button (toggle). There does not appear to be a nice way to do this in the API. I might just be missing something simple.
I tried the following with no results:
$("#myButton").button().click();
Any ideas how to handle that in this case are welcome. Note that it would be awesome to find a solution that applies for a buttonset as well.
Edit
Note that I need this particular functionality to simulate the user. Here's some code to illustrate the issue better:
function toggleBrushValue(hotkey, attributeName) {
shortcut.add(hotkey, function(e) {
//XXX: the missing part
开发者_Python百科 $("#" + attributeName).<something?>;
});
}
function increaseBrushValue(hotkey, attributeName) {
shortcut.add(hotkey, function(e) {
var currentSize = $("#" + attributeName).slider("value");
$("#" + attributeName).slider("value", currentSize + 1);
});
}
It took a while but finally I found a way around the issue. :) Here's my solution:
var $toggle = $("#" + attributeName);
$toggle.attr("checked", !$toggle.attr("checked")).button("refresh");
As jQuery UI toggles get their initial value via "checked", I decided to use that to my advantage. "refresh" makes sure its visual state gets updated as well.
Try using .toggle(), like the following:
$("#myButton").toggle(
function() {
$("#mySlider").slider("value", 42);
},
function() {
// something else...
}
);
It will work on a button-set too since you provide the correct selector. For example:
<input id="myButton" ...>
<input id="myButton" ...>
<input id="myButton" ...>
$('#myButton').toggle()
will be executed for each of the above elements. Additionally, If you need to interact with the button from within the function itself, use this
or $(this)
. For example:
$("#myButton").toggle(
function() {
alert($(this).attr('id'));
},
function() {
alert($(this).attr('name'));
}
);
