vb 调用javascript脚本函数

vb 能调用网页中的Javascript脚本函数吗？
<script type="text/javascript">
<!--
var theForm = document.forms['aspnetForm'];
if (!theForm) {
    theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
    if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
        theForm.__EVENTTARGET.value = eventTarget;
        theForm.__EVENTARGUMENT.value = eventArgument;
        theForm.submit();
    }
}
// -->
</script>

我想webbrowser中调用 __doPostBack，怎么做呀？？？

我要传递参数给function __doPostBack(eventTarget, eventArgument)
怎么办？

VB code:
WBDocument.parentWindow.execScript "doPostBack(" & text1 & "," & text2 & ")","javascript"

VB codeWBDocument.parentWindow.execScript"doPostBack("& text1&","& text2&")","javascript"

WebBrowser1.Document.parentWindow.execScript _
"doPostBack(" & irfc / tedpurd & "," & u4vhedqq & ")", &
