javascript ok取消弹出按钮

Question

我尝试了很多东西，但仍然可以从表单中访问.js文件：拜托，有人能告诉我它是如何完成的吗？

这就是我想说的：

 <script type="text/javascript">
    if (confirm("Press 'OK' to leave, or 'Cancel' if you want to stay: "))
    {         
       window.location="http://google.com";
    }
    else
    {         
      <a href="javascript:history.go(-1)">Go back</a> 
    }
  </script>

这就是我试图打电话的方式：

<input type="BUTTON" value="Back to Main Page" onclick= ??? >

谢谢。

Answer 1

var answer = confirm ("Press Ok to leave. Cancel to stay.")
   if (answer)
window.location="http://google.com"
   else
window.location="http://www.mysite.com/"

Answer 2

您正在JavaScript代码中添加HTML代码。你需要将它们分开。类似的东西：

document.write('<a href="javascript:history.go(-1)">Go back</a>');

会做到这一点。

Answer 3

您需要将代码设置为javascript function，就像这样

function sayHello()
{
  alert('hello');
}

按钮html：

<input type="BUTTON" value="Back to Main Page" onclick="javascript: sayHello();" >

//  start active and inactive confirm message box
    var Regionid = '@Model.RegionID';
    if (Regionid != 0) {
        $(function () {
            $('#inactive').change(function () {
                $("#ConformationDlg").html('@Constants.ChangeStatus');
                $("#ConformationDlg").dialog({
