[英]Callin ascx.cs function from .ascx
這是我的示例代碼。 我正在嘗試調用方法calculateCoordinates()
,該方法位於.ascx文件上的javascript中,它嘗試過OnClick
但它不起作用,現在我正在嘗試OnClientClick
,也無法工作。
//button
<asp:Button CssClass="button" ID="CalcCoord_Btn" runat="server" Text="Calcular Coordenadas" OnClientClick="javascript: calculateCoordinates();"/>
//also tried
<asp:Button CssClass="button" ID="CalcCoord_Btn" runat="server" Text="Calcular Coordenadas" OnClientClick="calculateCoordinates();"/>
<asp:Button CssClass="button" ID="CalcCoord_Btn" runat="server" Text="Calcular Coordenadas" OnClientClick="javascript: calculateCoordinates(); return false"/>
//.ascx javascript
<script type="text/javascript">
function calculateCoordinates() {
alert("calculateCoordinates");
var AddressLn1 = document.getElementById("AddressLine1");
var AddressLn2 = document.getElementById("AddressLine2");
var State = document.getElementById("State");
var Town = document.getElementById("City");
var Postcode = document.getElementById("ZipCode");
var Country = document.getElementById("State");
var address = AddressLn1.value + ', ';
address += AddressLn2.value + ', ';
address += Town.value + ', ';
address += Postcode.value + ', ';
address += Country.value;
// Make REST call to get geocoded information (that is, the coordinates for the address)
// This will use your call back procedure and return result in JSON format
var geocodeRequest = "http://dev.virtualearth.net/REST/v1/Locations?query=" + encodeURI(address) + "&output=json&jsonp=GeocodeCallback&key=" + credentials;
CallRestService(geocodeRequest);
//return false;
}
function CallRestService(request) {
alert("CallRestService");
var script = document.createElement("script");
script.setAttribute("type", "text/javascript");
script.setAttribute("src", request);
document.body.appendChild(script);
}
function GeocodeCallback(result) {
alert("GeocodeCallback");
var Lat = document.getElementById("hdnfldVariableLat");
var Long = document.getElementById("hdnfldVariableLong");
if (result &&
result.resourceSets &&
result.resourceSets.length > 0 &&
result.resourceSets[0].resources &&
result.resourceSets[0].resources.length > 0) {
Lat.value = result.resourceSets[0].resources[0].point.coordinates[0];
Long.value = result.resourceSets[0].resources[0].point.coordinates[1];
var location = new Microsoft.Maps.Location(Lat.value, Long.value),
pin = new Microsoft.Maps.Pushpin(location, { text: '2', draggable: true });
}
}
</script>
在calculateCoordinates()
方法末尾也嘗試了“ return false”。 但是它甚至不會給我任何警報,以查看實際上是否正在調用該方法...我知道這很簡單,但是我在做什么錯呢? 該方法calculateCoordinates()
已經過測試,就像一個魅力,所以我知道它的作品。
像這樣修復它。
<asp:Button CssClass="button" ID="CalcCoord_Btn" runat="server" Text="Calcular Coordenadas" OnClientClick="javascript: calculateCoordinates();"/>
var calculateCoordinates = function() {
alert("calculateCoordinates");
var AddressLn1 = document.getElementById("AddressLine1");
var AddressLn2 = document.getElementById("AddressLine2");
var State = document.getElementById("State");
var Town = document.getElementById("City");
var Postcode = document.getElementById("ZipCode");
var Country = document.getElementById("State");
var address = AddressLn1.value + ', ';
address += AddressLn2.value + ', ';
address += Town.value + ', ';
address += Postcode.value + ', ';
address += Country.value;
// Make REST call to get geocoded information (that is, the coordinates for the address)
// This will use your call back procedure and return result in JSON format
var geocodeRequest = "http://dev.virtualearth.net/REST/v1/Locations?query=" + encodeURI(address) + "&output=json&jsonp=GeocodeCallback&key=" + credentials;
CallRestService(geocodeRequest);
return false;
}
嘗試使用onclick事件而不是onClientClick。 可能會有所幫助!
