这是我的博客，我在博客中添加了以下代码。下面的代码可以像下面的示例一样在片段中正常工作，但是在我的博客中却无法正常工作，我应该在博客平台中使用它，如果我使用任何jquery库来使其正常工作。请参见下面的代码段，该代码段中的代码运行正常。我的目标是，如果在我的博客中同时显示了另一个窗口小部件，但同时显示了两个窗口小部件，则隐藏一个窗口小部件。小提琴的例子很好用
<script type="text/javascript">
var control1VisibleCheck = function () {
var now = new Date();
//TODO: modify this logic to your needs: have a look on the Date() object's members and methods to implement what you need
if (now.getSeconds() % 20 == 0) //I'd like to show control1 on even minutes
return true;
return false;
}
if (control1VisibleCheck())
document.getElementById('multi-search-groups').style.display = 'none';
else
document.getElementById('multi-search').style.display = 'none';
</script>

下面的代码工作正常
var control1VisibleCheck = function () {
var now = new Date();
//TODO: modify this logic to your needs: have a look on the Date() object's members and methods to implement what you need
if (now.getSeconds() % 2 == 0) //I'd like to show control1 on even minutes
return true;
return false;
}
if (control1VisibleCheck())
document.getElementById('multi-search-groups').style.display = 'none';
else
document.getElementById('multi-search').style.display = 'none';<div id="multi-search">
<select id="cmbColumn" name="cmbColumn">
<option value="" />Columns
<option value="apple+" />apple
<option value="grapes+" />grapes
</select>
<select id="cmbSidebar" name="cmbSidebar">
<option value="" />Sidebars
<option value="mango+" />mango
<option value="berry+" />berry
</select>
</div>
<div id="multi-search-groups">

<div id="control2" style="width: 200px; height: 100px; background-color: green;">
</div-->似乎您的小提琴也无法正常工作，如注释中所建议，在页面（文档）准备就绪后执行JavaScript：
(function() {
// your code here
});
(function() {
var control1VisibleCheck = function () {
var now = new Date();
//TODO: modify this logic to your needs: have a look on the Date() object's members and methods to implement what you need
if (now.getMinutes() % 2 == 0) //I'd like to show control1 on even minutes
return true;
return false;
}
if (control1VisibleCheck())
document.getElementById('multi-search-groups').style.display = 'none';
else
document.getElementById('multi-search').style.display = 'none';
});
