.animate() 在 jQuery 中，如果条件似乎不起作用
.animate() in jQuery and if condition seems to don't work
我不是 jQuery 方面的专家，我尝试创建一种按钮切换：
当我点击切换按钮 "Home/News" 时，内容也应该切换。
但这似乎行不通...尽管有 if 条件，但条件和 else 都已执行...我不明白。谁能告诉我哪里失败了？
这是 jsfiddle：https://jsfiddle.net/zgLsbw2h/1/
jQuery :
$(document).ready(function(){
function switchButton(){
console.log("coucou")
$('.onoffswitch').click(function(){
if($('.onoffswitch').hasClass('nothere')){
$('.container_slide_actu').animate({
left : 0}, 700);
$('.onoffswitch').removeClass('nothere');
}else{
$('.container_slide_actu').animate({
left : '-100%'}, 700);
$('.onoffswitch').addClass('nothere');
}
});
}
switchButton();
});
提前致谢。

更多解释（希望简化）：
我有两个 html 容器。当我点击按钮时，我想切换它们。默认情况下，我得到了 container1 ；当我点击 odd => container2 时；当我点击 even => container1...
部分截图说明：
-我网站的横幅（默认 => container1（屏幕截图上的 1））和幻灯片（谁过来横幅 => container2（屏幕截图上的 2））：http://prntscr.com/dpwxat
我添加 console.log('has nothere'); 和 console.log('nothere not present'); 只是为了确保 if 正常工作，并且在开始时注意到 if单击一次即可满足 和 else 条件。
不确定您要完成什么，但我将 add/remove class 行移到匿名函数中，以便在动画完成后执行。
$(document).ready(function(){
function switchButton(){
console.log("coucou")
$('.onoffswitch').click(function(){
if($('.onoffswitch').hasClass('nothere')){
console.log('has nothere');
$('.container_slide_actu').animate({
left : 0}, 700, function() {
// Animation complete.
$('.onoffswitch').removeClass('nothere');
});
}else{
console.log('nothere not present');
$('.container_slide_actu').animate({
left : '-100%'}, 700, function() {
// Animation complete.);
$('.onoffswitch').addClass('nothere');
});
}
});
}
switchButton();
});
请尝试告诉我。
你的动画进进出出的原因是因为onclick是运行两次。这样做的原因是因为您的目标是 "onoffswitch" class，您有不止一个。如果您将“#myonoffswitch”作为目标，它是一个 id，只针对一件事并且只会触发一次。我也清理了你的 JS。看看吧，告诉我你的想法。
$(document).ready(function(){
$('#myonoffswitch').on("click", function(){
if($("#myonoffswitch").is(':checked') == false) {
$('.container_slide_actu').animate({
left : 0}, 700);
}else{
$('.container_slide_actu').animate({
left : '-100%'}, 700);
