I have a jQuery tip function. I would like to create a button to turn on and turn off the function. I want it to be on by def开发者_如何学Goault.
Is it possible to create a link to turn on and off a function?
You can dynamically add and subtract event handlers with the bind and unbind functions.
$("#id").click( function() {
if ( HANDLER_IS_SET )
$("#button").unbind( "click");
else
$("#button").bind( "click", myEventHandlerFunction );
}
You can set a boolean to check if it's on or off, or bind and unbind a function.
var isOn = false;
$("#button").click(function(){ isOn = !isOn; });
$("#executebutton").click(MyFunction);
function MyFunction()
{
if (!isOn) return;
// do stuff
}
or
$("#button").click
(
function()
{
if ($("#executebutton").data("events").click != undefined)
$("#executebutton").unbind("click");
else
$("#executebutton").bind("click", MyFunction);
}
);
A little more info is needed, but you could use a global variable to toggle an if statement within the function so it doesn't execute anything, but the function will still be called.
