Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'
提问by Jarrod Farrell
Having a bit of an issue that might be staring me right at the face.
有一些问题可能正盯着我的脸。
var listitem = document.createElement("li").id = 'list' + x[i]
var listitem = listitem.innerHTML = '<button id="delete' + x[i] + '" class="button action" onclick="deleteuser(\'' + x[i] + '\')">Delete</button>' + x[i]
document.getElementById('userslist').appendChild(listitem)The bit of code is in a for loop on Javascript and from the error I can understand that the for loop is working as intended, but it's failing to append to the mentioned list with the error stated above.
这段代码在 Javascript 上的 for 循环中，从错误中我可以理解 for 循环按预期工作，但它未能通过上述错误附加到提到的列表中。

This is wrong
这是错误的
var listitem = document.createElement("li").id = 'list' + x[i]
It ends up storing the string in the variable listitemand not the object.
它最终将字符串存储在变量中listitem而不是对象中。
Your code should be
你的代码应该是
var listitem = document.createElement("li");
listitem .id = 'list' + x[i];
