Hello,
I want to to interact with javascript from c#. For this I was following the below link:
When I am trying to call any method from c# it gives me error missing function.
For eg: I have created a method in javascript like this.
mergeInto(LibraryManager.library, {
Hello: function () {
window.alert(“Hello, world!”);
},
});
and placed this script at path Assets/Plugins/WebGL/MyPlugin.jslib.
Then I am trying to access this method from c# like:
using UnityEngine;
using System.Runtime.InteropServices;
public class NewBehaviourScript : MonoBehaviour {
[DllImport("__Internal")]
private static extern void Hello();
void Start() {
Hello();
}
}
but it gives me
missing function : Hello
while running it on browser. Please screen shot for the same
Please Help me out! Thank you!
HI, @unity_mwF5s3xOpUdXNA.
I checked your code on my computer. Everything works perfectly!
Perhaps you made a mistake elsewhere 
My Code in C#
using System.Runtime.InteropServices;
using UnityEngine;
public class TestBrowser : MonoBehaviour {
[DllImport("__Internal")]
private static extern void Hello();
void Start()
{
Hello();
}
}
jslib:
mergeInto(LibraryManager.library, {
Hello: function () {
window.alert(“Hello, world!”);
},
});
Location jslib: Assets/Plugins/WebGL/MyPlugin.jslib
My reply over here is very late entry considering the question has been asked over a ago. So I faced a similar problem.
Your javascript and C# code seems fine which means the problem lies somewhere else. In my case I had forgot to change the .jslib plugin platforms from Unity’s inspector window. When I was receiving missing function error, my .jslib plugin was checked into Editor platform. I unchecked it and checked WebGL platform. After creating the build everything worked as it was supposed to be.
I’m attaching a screenshot so you or anyone else facing a similar problem can understand.
