Question

我有以下代码用于在屏幕的一角显示一个对话框，一旦我点击网页中的链接，它就会显示出来。我想只使用HTML和Javascript（现在没有时间或带宽来学习jQuery）。无论我尝试什么，我点击链接后都没有显示。有什么想法吗？谢谢！

这是我的html文件，包含所有必要的元素：

<!DOCTYPE html>
<head>
    <title>Restraint Dialog</title>

    <style>
    .modalDialog {

Answer 1

在脚本中更改以下内容

function restraintEditor() {
    var restrCont = document.getElementById("restraintContainer");
    restrCont.style.opacity="1";
}

}
