[英]Can't get global variables inside the function (javascript)
var selection = document.getElementById('selection');
var closed = true;
function openorclosebar() {
if(closed == false){
selection.style.webkitAnimation='bounceOutDown 1s forwards';
selection.style.animation='bounceOutDown 1s forwards';
closed = false;
}
else{
selection.style.webkitAnimation='bounceInUp 1s forwards';
selection.style.animation='bounceInUp 1s forwards';
closed = true;
};
}
如何獲取全局變量“選擇”和“封閉”以使用它們。 我嘗試了“ window.selection”和“ window.closed”,但沒有任何幫助。 如果您有想法,請幫助我,這是非常重要的項目。
全局closed
變量是只讀的:這是window
的.closed
屬性- 之前已經發生過.name
:-)
使用IEFE將變量設為本地:
(function() {
var selection = document.getElementById('selection');
var closed = true;
function openorclosebar() {
if(!closed) {
selection.style.webkitAnimation='bounceOutDown 1s forwards';
selection.style.animation='bounceOutDown 1s forwards';
closed = false;
} else {
selection.style.webkitAnimation='bounceInUp 1s forwards';
selection.style.animation='bounceInUp 1s forwards';
closed = true;
}
}
}());
還可以查看瀏覽器環境中的其他不安全名稱 。
