我试图在window.onload上存储变量的值以供以后使用

Question

不工作。为什么？我想这样做是因为seoquake栏为我的源代码添加了dis并且它混淆了我使用的for循环基于文档的div长度

window.onload = var dekki = function window(){
    var div = document.getElementsByTagName('div');
    divLength = div.length;
    return divLength;
}

document.write(dekki);

Answer 1

window.onload = var dekki = function ...

您在这里为'dekki'分配了一个功能。相反，做

window.onload = function () {
    var div = document.getElementsByTagName('div');
    window.dekki = div.length;
}

Answer 2

只需将它们分开，然后就可以了。

<script type="text/javascript">
var showDivLength = function () {
    var div = document.getElementsByTagName('div');
    divLength = div.length;
    if (divLength > 0)
        div[divLength-1].innerHTML = divLength;
    return divLength;
}
window.onload = function () {
    showDivLength();
}
