C#直接調用webBrowser JavaScript

直接調用JavaScript

webBrowser1.Document.InvokeScript("FunctionName");

調用帶有參數的JavaScript

webBrowser1.Document.InvokeScript("FunctionName",new object[]{obj1});

 

向webBrowser1中添加新的javascript,將javascript放在txt中,代碼容易寫

TXT內容:

function SubmitUser()

{

document.Login.USER.value     = 'USER';

document.Login.PASSWORD.value = 'PASSWORD';

document.Login.target.value   = 'https://www.myprs.com';

document.Login.submit();

}

 

調用代碼

 HtmlDocument document = webBrowser1.Document;

HtmlElement htmlElement = document.CreateElement("Script");

htmlElement.SetAttribute("Language", "JavaScript");

FileStream fs = new FileStream(strFile, FileMode.Open);

StreamReader sr = new StreamReader(fs);

string strjs = sr.ReadToEnd();

htmlElement.SetAttribute("text", strjs);

document.Body.AppendChild(htmlElement);

object ss =  document.InvokeScript(FunctionName);

sr.Close();

fs.Close();

return ss;

 

 

 

有復雜參數的,可以新建Function調用注意FunctionName大小寫問題

<script language="javascript">

    var fun = function()

    {

            .......

    }

    onLoadFunctionStack(window, fun);

</script>

 

<script language="javascript">

    function CALLFUN() {

        var fun = function()

　　　{               

        }

        onLoadFunctionStack(window, fun);

    }

</script>

 

將復雜參數在Function中利用Javascript代碼直接賦值

<form name="QueryForm" method="post" action="/myprs/internal/myprsQuery.do;jsessionid=4CB44026578AC5443249606A945259D5.g1u0117c"

onsubmit="return validateForm(this) && onSubmitBasket(this) && displayPnLimitWarningNoParams();">

調用onsubmit中的這段代碼 (this代表這個form)可以改寫成

function reValue()

{

var frms=document.forms["QueryForm"];

return validateForm(frms) && onSubmitBasket(frms) && displayPnLimitWarningNoParams();

}

 

Javascript中document很有用
