如果隐藏，则单击时反转动画

标签： javascript jquery html css animation

我试图在导航栏隐藏并向左滑动后向左滑动“切换按钮”，然后在显示导航栏时将其滑回原始位置。这就是我现在正在尝试的。

这不起作用：

public function addTask(Task $task)
{
    if (!$this->tasks->contains($task)) {
        $this->tasks->add($task);
        $task->addCategory($this);
    }
}

public function removeTask (Task $task)
{
    if ($this->tasks->contains($task)) {
        $this->tasks->remove($task);
        $task->removeCategory($this);
    }
}

当我删除else块上的animate方法时，一切似乎都有效，当我将其添加回来将“$ toggle”按钮反转到原始位置时，没有代码可以工作....任何帮助都非常感激！

编辑：在

下添加了代码段 

$(document).ready(function() {
  var $toolbar = $("#toolbar");
  var $toggle = $("#toggle");

  $toggle.on("click", function() {
    if ($toolbar.is(":visible")) {
        $toolbar.toggle(500);
        $toggle.animate({
            left: 0
        }, 500);
    } else if ($toolbar.is(":hidden")) {
        $toolbar.toggle(500);
        $toggle.animate({
            left: 20.5%
        }, 500);
    }
  });
});

$(document).ready(function() {
  var $toolbar = $("#toolbar");
  var $toggle = $("#toggle");

  $toggle.on("click", function() {

	if ($toolbar.is(":visible")) {
		$toolbar.toggle(500);
		$toggle.animate({
			left: 0
		}, 500);
	} else if ($toolbar.is(":hidden")) {
		$toolbar.toggle(500);
	}
  });
});

如果没有看到你的标记，就像其他海报所提到的那样有点困难，但我会在没有看到你的来源的情况下对它进行评价。

$(document).ready(function() {
    var $toolbar = $("#toolbar");
    var $toggle = $("#toggle");

    $toggle.on("click", function() {
        $toolbar.animate({
            width:'toggle'
        }, 750);
    });
});

您必须将按钮的left属性设置为字符串。在JavaScript中不允许使用“％”符号。修正如下：

$(document).ready(function() {
  var $toolbar = $("#toolbar");
  var $toggle = $("#toggle");

  $toggle.on("click", function() {

	if ($toolbar.is(":visible")) {
		$toolbar.toggle(500);
		$toggle.animate({
			left: "0"
		}, 500);
	} else if ($toolbar.is(":hidden")) {
		$toolbar.toggle(500);
    $toggle.animate({
      left: "20.5%"
    });
	}
  });
});

JQuery可以像你看到的那样处理它。
