问题
I have some <li>
Items in my HTML Page like this
<li id="A1" class="ui-state-default">Item 2</li>
<li id="A2" class="ui-state-default">Item 3</li>
<li id="A3" class="ui-state-default">Item 4</li>
<li id="A4" class="ui-state-default">Item 5</li>
I called It using Javascript and Jquery like this to get the Id and Index of the <li>
elements
function LiOrder() {
var order = $('li').map(function (i) {
return { id: this.id, index: i };
}).get();
PageMethods.GetServerResponse(order, OnSuccess, OnFail);
}
function OnSuccess(arg) {
alert(arg);
}
WebMethod Written in Aspx.cs Page is this
[WebMethod]
public static string GetServerResponse(string[,] LiOrder)
{
return LiOrder[0,0];
}
But when I try to execute it I get Error like this in Google Chrome (Javascript Console)
POST http://localhost:2453/ERP29.1.13/Production/LifeCycleRegistration.aspx/GetServerResponse 500 (Internal Server Error) ScriptResource.axd:6979
What might be the reason for this error. I could pass a string to WebMethod like this. But when it comes to Array, its like this. Please Help me to resolve this
回答1:
JSON.stringfy resolved my issue. I changed my code like this
var LiArr=JSON.stringify(order);
PageMethods.GetServerResponse(LiArr, OnSuccess, OnFail);
