我的javascript ..

Hello everyone,

I want to execute my code behind function in javascript which is on the same aspx page.

my javascript..

<script type="text/javascript">

    var xmlhttp;
    function loadXMLDoc(url, cfunc) {
        if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
        }
        else {// code for IE6, IE5
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }
        if (xmlhttp != null) {
            xmlhttp.onreadystatechange = cfunc;
            xmlhttp.open("GET", url, true);
            // xmlhttp.setRequestHeader("Content-Type", "text/xml; charset=utf-8");
            xmlhttp.send();
        }
        else {
            alert("Page can not process");
        }
    }


    function insertSealDetails()
    {
        // var username = $('#username').val();
        // var password = $('#password').val();
        var sealname = document.getElementById('<%= txtSealName.ClientID %>').value;
        var sealdesc = document.getElementById('<%= txtSealDescription.ClientID %>').value;
        var url = "";
        if ((sealname == null || sealname == ''))
        {
            alert("Please enter Sealname.");
            return;
        }

        url = "AjaxFunctions.aspx?sealname=" + sealname + "&sealdesc=" + sealdesc + "&Action=insertsealdetails";
        loadXMLDoc(url, function () {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                var t = xmlhttp.responseText;
                t = t.replace(/^(.*\n)*.*<html/i, "<html");

                t = t.replace(/<\/html>(.*\n)*.*$/i, "</html>");
                var parser = new DOMParser();
                var dom = parser.parseFromString(t, "text/xml");
                //  x = dom.getElementById("responseText").firstChild;
                //alert(x);
                var response = dom.childNodes[0].getAttribute("name");
                if (response == "1") {
                    <%FillGDVSeal(); %>;
                }
                else if (response == "0") {
                    //alert('Invalid login !!');
                }
            }

        });
    }


    </script>

my code behind method..

 protected void FillGDVSeal()
    {
        lbMessage.Text = "Inserted";
        

    }

javascript和代码隐藏文件是.aspx页面相同..



我无法获得任何输出...请帮助我...

推荐答案

（'＃username'）。val（）;
// var password =

('#username').val(); // var password =

（'＃password'）。val（）;
var sealname = document.getElementById（'<％ = txtSealName.ClientID ％> '）。值;
var sealdesc = document.getElementById（'<％ = txtSealDescription.ClientID ％> '）。值;
var url =;
if（（sealname == null || sealname ==''））
{
alert（请输入Sealname。）;
返回;
}

url =AjaxFunctions.aspx？sealname =+ sealname +& sealdesc =+ sealdesc +& Action = insertsealdetails;
loadXMLDoc（url，function（）{
if（xmlhttp.readyState == 4&& xmlhttp.status == 200）{
var t = xmlhttp.responseText;
t = t.replace（/^(.* \ n）*。* < html / i， < html）;

< span class =code-attribute> t = t.replace（/< \ / html > （。* \ n）*。*

('#password').val(); var sealname = document.getElementById('<%= txtSealName.ClientID %>').value; var sealdesc = document.getElementById('<%= txtSealDescription.ClientID %>').value; var url = ""; if ((sealname == null || sealname == '')) { alert("Please enter Sealname."); return; } url = "AjaxFunctions.aspx?sealname=" + sealname + "&sealdesc=" + sealdesc + "&Action=insertsealdetails"; loadXMLDoc(url, function () { if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { var t = xmlhttp.responseText; t = t.replace(/^(.*\n)*.*<html/i, "<html"); t = t.replace(/<\/html>(.*\n)*.*

/ i，< / html > ）;
var parser = new DOMParser（）;
var dom = parser.parseFromString（t，text / xml）;
// x = dom.getElementById（responseText）。firstChild;
// alert（x）;
var response = dom.childNodes [0] .getAttribute（name）;
if（response ==1）{
<％ FillGDVSeal（）; ％> ;
}
else if（response ==0）{
// alert（'Invalid login !!'）;
}
}

}）;
}


< / script < span class =code-keyword>>

我的代码隐藏方法..

protected void FillGDVSeal（）
{
lbMessage.Text =已插入;


}

/i, "</html>"); var parser = new DOMParser(); var dom = parser.parseFromString(t, "text/xml"); // x = dom.getElementById("responseText").firstChild; //alert(x); var response = dom.childNodes[0].getAttribute("name"); if (response == "1") { <%FillGDVSeal(); %>; } else if (response == "0") { //alert('Invalid login !!'); } } }); } </script> my code behind method.. protected void FillGDVSeal() { lbMessage.Text = "Inserted"; }

javascript和代码隐藏文件是.aspx页面相同..
