通过Javascript控制ActiveX控件
[英]Controlling ActiveX Control via Javascript
问题描述
I am trying to use some software from WonderWare via ActiveX. 
我正在尝试通过ActiveX使用WonderWare的某些软件。 I have gotten the object to appear, but I am want to pass some parameters to it and eliminate having to setup the object everytime. 我已经显示了该对象，但是我想向其传递一些参数，而不必每次都设置该对象。 There are two versions of the control ActiveX and .NET. 有两个版本的控件ActiveX和.NET。 I haven't gotten the .NET control to work at all, but I can get the ActiveX one / just not the parameters. 我还没有使.NET控件正常工作，但是我可以使ActiveX成为一个/而不是参数。
Here is what the manual says about it: 这是手册说明的内容：
The aaHistClientTrend control allows you to run the Wonderware Historian Client Trend program (or a functional subset) from within the Wonderware InTouch HMI software or a .NET container like Visual Basic .NET or Internet Explorer.
The HTML code that I have: 我拥有的HTML代码：
<html>
<head>
<body>
<object id="aTrend1" classid="clsid:E08609F1-58CC-11D3-B1CF-00105AA45077" viewastext="" height="100%" width="100%" />
</body>
</head>
</html>
I try to pass the parameter via: 我尝试通过以下方式传递参数：
<script language="JavaScript">
document.aTrend1.TagPickerVisible = false;
</script>
And it crashes internet explorer. 并且它使Internet Explorer崩溃。
EDIT : Any ideas? 编辑：有什么想法吗？

I figured out a way to do it. 我想出了一种方法。 Not sure it's the only way, but it works. 不确定这是唯一的方法，但是它可以工作。
<html>
<head>
<script>
function fxnTrend()
{
aTrend1.ToolBarVisible = false;
aTrend1.TagPickerVisible = false;
aTrend1.RealTimeMode = true;
aTrend1.TimeBarVisible = false;
aTrend1.GridVisible = false;
}
fxnTrend();
</script>
<body onLoad="fxnTrend()">
<object id="aTrend1" classid="clsid:E08609F1-58CC-11D3-B1CF-00105AA45077" viewastext="" height="100%" width="100%" />
</body>
</head>
