如何在asp.net中的下拉选择索引更改中调用javascript函数 [英] how to call function of javascript in dropdown selected index change in asp.net

问题描述

这里我绑定了数据库和数据库中的数据。 onselectedindexchanged databind选项。

我想在给定的时候调用javascript函数。

我试过但是下拉列表没有工作：

Here i bind data from database & onselectedindexchanged databind option.
I want to call function of javascript upon given.
I've tried it but drop down list not working:

script type="text/javascript">
        $(document).ready(function () {
            $("#ddlpostoffice").onchange(function () {
                var geocoder = new google.maps.Geocoder();
                var strSearch = document.getElementById('txtSearch').value;
                geocoder.geocode({ 'address': strSearch }, function (results, status) {
                
                        map = new google.maps.Map(document.getElementById("Map_Div"), myOptions);
                        var marker = new google.maps.Marker({
                            position: new google.maps.LatLng(x, y),
                            map: map,
                            title: strSearch
                        });
                        s
                        var infowindow = new google.maps.InfoWindow({
                            content: strSearch
                        });
                        infowindow.open(map, marker);
                        google.maps.event.addDomListener(window, 'load');
                    } else {
                        document.getElementById('txtSearch').value = "This Location Map Not Found";
                    }
                });
            });
        });
    </script







 asp:DropDownList CssClass="select" ID="ddlpostoffice" runat="server" 

              AutoPostBack="True"    onselectedindexchanged="ddlpostoffice_SelectedIndexChanged" onchange="return false;"   

推荐答案

（ document ）。ready（ function （）{

(document).ready(function () {

（ #ddlpostoffice）。onchange（ function （）{
var geocoder = new google.maps.Geocoder（）;
var strSearch = document .getElementById（' txtSearch'）。value;
geocoder.geocode（{' address'：strSearch}， function （结果，状态）{

map = new google.maps。 Map （ document .getElementById（ Map_Div），myOptions）;
var marker = new google.maps.Marker（{
position： new google.maps.LatLng（x，y），
map：map，
title：strSearch
}）;
s
var infowindow = ne w google.maps.InfoWindow（{
content：strSearch
}）;
infowindow.open（地图，标记）;
google.maps.event.addDomListener（ window ，' 负载'）;
} else {
document .getElementById（' txtSearch'）。value = 找不到此位置图;
}
}）;
}）;
}）;
< / script







asp：DropDownList CssClass = 选择 ID = ddlpostoffice runat = server

AutoPostBack = True onselectedin dexchanged = ddlpostoffice_SelectedIndexChanged onchange = return false;

("#ddlpostoffice").onchange(function () { var geocoder = new google.maps.Geocoder(); var strSearch = document.getElementById('txtSearch').value; geocoder.geocode({ 'address': strSearch }, function (results, status) { map = new google.maps.Map(document.getElementById("Map_Div"), myOptions); var marker = new google.maps.Marker({ position: new google.maps.LatLng(x, y), map: map, title: strSearch }); s var infowindow = new google.maps.InfoWindow({ content: strSearch }); infowindow.open(map, marker); google.maps.event.addDomListener(window, 'load'); } else { document.getElementById('txtSearch').value = "This Location Map Not Found"; } }); }); }); </script asp:DropDownList CssClass="select" ID="ddlpostoffice" runat="server" AutoPostBack="True" onselectedindexchanged="ddlpostoffice_SelectedIndexChanged" onchange="return false;"
