jQuery Toggle —一种功能一键单击然后另一种

Question

Here's what I would like to do in pseudocode form.

Bind Two Functions to Click Event

On 1st/Odd Clicks Do FunctionA()

On 2nd/Even Clicks Do FunctionB()

The .toggle() function seems to not be designed for this.

I'm sure this exists in jQuery but my googling hasn't resulted in anything. :)

Answer 1

I don't see how this isn't exactly what toggle is designed for...

$('#someEl').toggle(FunctionA, FunctionB);

You may be confused by the other toggle function that exists in jQuery, which won't be called if you pass functions as the arguments.

Answer 2

var i=1;
$(".a").click (function () {if (i%2!=0) FunctionA();i++;});
$(".a").click (function () {if (i%2==0) FunctionB();i++;});

Answer 3

You just need to ask Google the right question ;)

$(selector).toggle(function(),function(),function(),...)

• function() Required. Specifies a function to run every EVEN time the element is clicked
• function() Required. Specifies a function to run every ODD time the element is clicked
• function(),... Optional. Specifies additional functions to toggle between
