Question

我试图隐藏，然后点击显示表格行。该行不会隐藏，然后在点击链接时显示。

我无法让它发挥作用。这是一个jsfiddle：

我的HTML和JavaScript：

<!DOCTYPE html>
<html>
<head>
<link href="results.css" rel="stylesheet" type="text/css">
<script>
var ViewModel = function() {
    var self = this;
    self.showRow = ko.observable(false);
    self.toggleVisibility = function() {
        self.showRow(!self.showRow());
    };
};
ko.applyBindings(new ViewModel());
</script>
<title></title>
</head>
<body>
<img alt="" src=

style="padding-top:0px;" width="100%"><br>

<p>Check the box next to a Scholarship you would like to save and hit the
SAVE button.</p>

在填充DOM之后，您必须创建敲除绑定。因此，要么将脚本向下移动（最好在</body>标记之前），要么在DOM加载时调用它。
