通过 document.onload 创建表不会 function
[英]creating table via document.onload won't function

I'm wondering as to why the following ceases to function, for whatever peculiar reason:

Are you sure you don't mean window.onload ?你确定你不是指window.onload吗？
window.onload=function() {
table = document.createElement("table");
table.setAttribute("border", "1");
document.body.appendChild(table);
};

EDIT编辑
With some extra html created for demonstration purposes:为演示目的创建了一些额外的 html：
window.onload=function() {
table = document.createElement("table");
table.setAttribute("border", "1");
document.body.appendChild(table);
tbody = document.createElement('tbody');
tr = document.createElement('tr');
td = document.createElement('td');
td.innerHTML = "test";
table.appendChild(tbody);
tbody.appendChild(tr);
tr.appendChild(td);
};

Now, if you're thinking of the body tag's onload attribute, you could do:现在，如果您正在考虑 body 标签的 onload 属性，您可以这样做：
<body onload="my_onload();"></body>
function my_onload() {
table = document.createElement("table");
table.setAttribute("border", "1");
document.body.appendChild(table);
tbody = document.createElement('tbody');
tr = document.createElement('tr');
td = document.createElement('td');
td.innerHTML = "test";
table.appendChild(tbody);
tbody.appendChild(tr);
tr.appendChild(td);
};

Note, however, this is the same as window.onload .但是请注意，这与window.onload相同。 In fact, you can't do both window.onload=... and <body onload="... , since the body onload will override the JS and only one will run.事实上，你不能同时做window.onload=...和<body onload="... ，因为 body onload 会覆盖 JS，只有一个会运行。
