綁定（）和click（）函數

Question

解除綁定（）我有這樣的代碼：

$('#people_nav>.prev, #people_nav>.next').click(function(){ 

    // Here I need to disable event of click for needed elements, see code below 
    $('#people_nav>.prev, #people_nav>.next').unbind('click'); 

    ... 
    code 
    ... 

    // Here I need resume event for click() function. How? 

}); 

我怎樣才能恢復事件click()功能？它應該在click(function(){...}); ...

Answer 1

您可以使用命名函數。像

var element = $('#people_nav>.prev, #people_nav>.next'); //cache for better performance 
var yourFunction = function() { 
    // Here I need to disable event of click for needed elements, see code below 
    element.off('click'); //unbind event 
     ... 
    code 
     ... 
    // Here I need resume event for click() function. How? 
    element.click(yourFunction); 
}; 
element.click(yourFunction); 

但是什麼東西，我會建議使用on()和off()

Answer 2

你只需要使用off

$('#people_nav>.prev, #people_nav>.next').off('click'); 

如果jQuery的版本> = 1.7寧願on和off方法而不是bind和unbind方法

Answer 3

您可以使用on()和off()是什麼，以及一個名爲功能

var elements = $('#people_nav > .prev, #people_nav > .next'); 

elements.on('click', doStuff); // bind handler 

function doStuff() { 

    elements.off('click'); // unbind handler 

    /*... 
    code 
    ...*/ 

    elements.on('click', doStuff); // rebind handler 
});
