var li1 = document.querySelector("nav ul li:nth-child(1)") li1.onclick = function(){ window.location.href = ["index.html"] } var li2 = document.querySelector("nav ul li:nth-child(2)") li2.onclick = function(){ window.location.href = ["2.html"] } var li3 = document.querySelector("nav ul li:nth-child(3)") li3.onclick = function(){ window.location.href = ["3.html"] } var li4 = document.querySelector("nav ul li:nth-child(4)") li4.onclick = function(){ window.location.href = ["4.html"] }有报错

根据你提供的代码，我并没有看到明显的报错。但是，我注意到你在 `window.location.href` 中传递的参数是一个数组，而不是一个字符串，这可能会导致跳转不成功。你可以把数组改为字符串，例如：

li1.onclick = function(){
    window.location.href = "index.html";
}

li2.onclick = function(){
    window.location.href = "2.html";
}

li3.onclick = function(){
    window.location.href = "3.html";
}

li4.onclick = function(){
    window.location.href = "4.html";
}

这样就可以正常跳转页面了。
