WebGL手机端弹出输入框

实现原理是使用JS调用浏览器的默认提示框，默认提示框可以呼出软键盘，（注意此时呼出的提示框会阻塞，unity会不工作，就算你勾选了Run in BackGround），关掉提示框，unity会再次工作

网上给的解决方法是自定义呼出模板，而不是用默认提示框（博主没试过）

1，创建JS代码（放在Plugin中，这方面Unity官网有介绍如何制作unity可调用的JS的操作方法），Unity调用JS

JS代码

 mergeInto(LibraryManager.library, {

    StringReturnValueFunction: function ()
    {
        var returnStr = window.location.search;
        var buffer = _malloc(lengthBytesUTF8(returnStr)   1);
        writeStringToMemory(returnStr,buffer);
        return buffer;
    },

    ShowKeyboard: function (str)   //这个就是呼出浏览器默认提示框的方法
    {
        var returnStr = prompt("", Pointer_stringify(str)); //呼出提示框方法，具体百度
        if(returnStr == undefined)
        {
           return "";
        }
        var buffer = _malloc(lengthBytesUTF8(returnStr)   1);
         writeStringToMemory(returnStr,buffer);
        return buffer;
    },

});

Unity调用

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;
using System.Runtime.InteropServices;
using System;

[RequireComponent(typeof(InputField))]
public class KeyboardClassInput : MonoBehaviour, ISelectHandler
{

    [DllImport("__Internal")]
    private static extern string ShowKeyboard(string str);

    string str;

    private InputField inputField;

    private void Awake()
    {
		inputField = GetComponent<InputField>();
	}

    public void Update()
    {
        if (str != null&&str!=""&&!string.IsNullOrEmpty(str))
        {
            inputField.text= str;
        }
    }

    public void OnSelect(BaseEventData data) 
    {
      
#if UNITY_EDITOR
        return;
    #endif
        str = ShowKeyboard("Enter Name");
    }
