如何在Javascript中读取从C＃传递的params object []项目？

Question

I am doing a simple program in Silverlight to inkove javascript function in silverlight.

The silverlight function is as under

void InvokeJS(params object[] items)
{
object result = System.Windows.Browser.HtmlPage.Window.Invoke("JSFunction", items);
}

Pasing value to this function is happening as under

  InvokeJS((object)new object[]{ (object)"10", (object)"20"})

And the JS function is as under

function JSFunction(params) {
            alert(params);
        }

Now how to read the params value in javascript?

Answer 1

To the called function, the params array is just that, an array.

In this case you will have an array that looks like this:

[ [ "10", "20" ] ]

Answer 2

The params variable is just the first of many arguments being passed in. You can access the other arguments using the following syntax:

alert(this.arguments[0]);
alert(this.arguments[1]);
alert(this.arguments[2]);

If you're passing all the arguments in a single variable, it will be an array so use:

alert(params[0]);
alert(params[1]);
alert(params[2]);

Answer 3

我知道了

alert(params[0]); alert(params[1]);
