如何在winforms中的WebBrowser控件中调用javascript? [英] How to call javascript inside a WebBrowser control in winforms?

问题描述

我想像这样调用 javascript 函数Goto":

I want to call the javascript function 'Goto' like this :

javascript:Goto('DM_NEW_OBJECT.ASPX?DM_CAT_ID=2063&DM_PARENT_ID=2217&INPUTSELECTION=&DM_OBJECT_ID=0&PACK_ID=0&CASE_ID=0&mode=0&SITE=Default');

该函数位于 DefaultGeneral.aspx 页面中，我需要从 WebBrowser 控件中调用它

the function is located in the DefaultGeneral.aspx page, and i need to call it from within a WebBrowser control

webBrowser1.Navigate("http://mySite/DefaultGeneral.aspx");

你有什么想法吗?谢谢.

Do you have any idea ? Thank you.

推荐答案

由于您使用的是 WebBrowser 对象，因此我假设这实际上是一个 Windows 窗体问题，而不是一个 asp.net 问题.

Since you are using a WebBrowser object, I will assume that this is actually a Windows forms question and not an asp.net question.

您应该查看 InvokeScript 网页浏览器的功能.

You should look at the InvokeScript function of the web browser.

假设您的网页具有以下功能:

Let's say your webpage has the following function:

无参数:

<script type="text/javascript">
    // Function Without Parameters
    function JavaScriptFunctionWithoutParameters() {
        outputID.innerHTML = "JavaScript function called!";
    }
</script>

您可能希望这样称呼它:

You would want to call it the following way:

this.webBrowser.InvokeScript("JavaScriptFunctionWithoutParameters");

带参数:

<script type="text/javascript">
    // Function With Parameters
    function Goto(someParameter) {
        outputID.innerHTML = someParameter;
    }
</script>

你可以这样称呼它:

object[] param = new object[1];
param [0] = "DM_NEW_OBJECT.ASPX?DM_CAT_ID=2063&DM_PARENT_ID=2217&INPUTSELECTION=&DM_OBJECT_ID=0&PACK_ID=0&CASE_ID=0&mode=0&SITE=Default";
this.webBrowser1.Document.InvokeScript("Goto", param );
