尽管样式属性在样式表内部不区分大小写,但样式的 JavaScript API 区分大小写。因此,设置style.Left
将不起作用,因为正确的属性名称是left
。
document.getElementById("sidebarButton").style.left = '0';

你有一个拼写错误document.getElementById("sidebarButton").style.Left应该是document.getElementById("sidebarButton").style.left
var lastState = false;
function sideButtonClicked() {
if (!lastState) {
//open
lastState = true
document.getElementById("mySidebar").style.width = "250px";
document.getElementById("main").style.marginLeft = "250px";
document.getElementById("sidebarButton").style.left = "250px";
} else {
//close
lastState = false
document.getElementById("mySidebar").style.width = "0px";
document.getElementById("main").style.marginLeft = "0px";
document.getElementById("sidebarButton").style.left = "0px";
}
}
