我的for循环在JavaScript中不工作，我怀疑我的我； getlengthLi()函数中断。 我自己测试了getLengthLI函数，它返回了一个数字，所以它可以工作，但是当我在for循环中使用它时，它会中断，为什么呢？
这是我的代码
null
function getLengthLi() {
var e = document.querySelectorAll('#list > li').length;
return e;
}
function checkTicks() {
var Text = ['text0', 'text1', 'text2', 'text3', 'text4', 'text5', 'text6', 'text7', 'text8', 'text9', 'text10', ]
for (i = 1; i < getLengthLi(); i++) {
document.write(Text[i]);
}
}<center>

我在控制台中没有得到任何结果，屏幕上也没有显示任何内容，但是，当我使用时，我； 6那么它就能工作，所以我的getLengthLI函数就是问题所在。
请检查一下它是否对你有用
null
function getLengthLi(){
var e = document.querySelectorAll('#list > li').length;
return e;
}
function checkTicks(){
var Text = ['text0','text1','text2','text3','text4','text5','text6','text7','text8','text9','text10',]
for(i = 0;i < getLengthLi();i++){
document.write(","+Text[i]);
}
}
checkTicks();<ul id="list" style="list-style: none;">
