Question

我在javascript上有这段代码：

         function getListOfPOI() {
            geocoder = new google.maps.Geocoder();
            var address = document.getElementById('tbCity').value;

            geocoder.geocode({ 'address': address }, function (results, status) {
                if (status == google.maps.GeocoderStatus.OK) {
                    map.setCenter(results[0].geometry.location);
                    var request = {
                        location: results[0].geometry.location,
                        radius: 8000,
                        types: all //['store']
                    };
                    infowindow = new google.maps.InfoWindow();
                    var service = new google.maps.places.PlacesService(map);
                    service.nearbySearch(request, callback);
                } else {
                    alert('Geocode was not successful for the following reason: ' + status);
                }
            });

            return true;
        }

我用下面的按钮调用此功能：

<asp:Button ID="btnAddCity" Height="20px" Text="Add" runat="server" OnClientClick="return getListOfPOI();" OnClick="btnAddCity_Click" UseSubmitBehavior="false"    />

OnClientClick完美无缺，但未触发OnClick功能。我该怎么办？提前感谢您的见解。

触发JavaScript Code + Server代码的另一种方法是在我们使用ClientScript.RegisterStartupScript并调用我们的JavaScript函数时执行以下操作！

在.ASPX页面中

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script>
        function clientTestClick() {
            document.write("Test!");
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="TestButton" Text="Test Me" UseSubmitBehavior="false" OnClick="TestButton_Click" runat="server"/>
    </div>
    </form>
</body>
</html>

取决于语言背后的代码..

<强> C＃：

protected void TestButton_Click(object sender, EventArgs e)
{
    ClientScript.RegisterStartupScript(Page.GetType, "JavaScript", "clientTestClick();", true);

    /*  PUT YOUR SERVER CODE HERE */
}

<强> VB.NET：

Protected Sub TestButton_Click(sender As Object, e As EventArgs) Handles TestButton.Click

    ClientScript.RegisterStartupScript(Me.GetType(), "JavaScript", "clientTestClick()",True)

    Dim x As String 
    x="hello" 'You can set a debug-point here and see that this will fire

End Sub

希望这有帮助，让我知道！

所以在@lucidgold的帮助下，终于现在正在工作！解决方案是在按钮服务器端调用javascript函数。经过调整后，这里有完整的解决方案：

我删除了JavaScript函数的返回true
删除按钮上的useSubmitBehaviour属性：
<asp:Button ID="TestButton" Text="Test Me" OnClick="TestButton_Click" runat="server"/>
在C＃中运行RegisterStartupScript，如下所示：
ClientScript.RegisterStartupScript(GetType(), "script", "<script type ='text/javascript'> getListOfPOI(); </script>");

onOnClientClick正在运行，但onClick不能在asp.net上运行
