Unity用ExternalCall实现webplayer读写。

Application.ExternalCall

 

 

 

public static void ExternalCall(string functionName, params object[] args);

Parameters

Description

Calls a function in the containing web page (Web Player only).

This will call JavaScript function functionName in the web page that contains the web player, passing given arguments to it. Supported argument types are the primitive types (string, int, float, char) and arrays of them. Any other objects are converted to string (using ToString method) and passed as strings.

The function is called non-blocking, i.e. ExternalCall immediately returns without waiting for the function that was called to complete.

The number of passed arguments can be varying:

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    void Example() {
        Application.ExternalCall("MyFunction1");
        Application.ExternalCall("MyFunction2", "Hello from Unity!");
        Application.ExternalCall("MyFunction3", "one", 2, 3.0F);
    }
}

The functions to be called are just declared in the HTML page using standard syntax, for example:

 

	// This should be contained in the host page in the appropriate <script> element.
	// Using the above call from Unity, this will receive
	// "Hello from Unity!" as the argument.
	function MyFunction2( arg )
	{
		alert( arg );
	}

如果是些xml文件的话，只能把大量参数以字符串数据的方式传送给javascript，再在javascript中调用activex控件来保存数据。
