WebDomHandling

A Swift Package for handling JavaScript code between WebKit and Swift implemented by WebKit.

Quick Start

Importtant

You have to set delegate to able to handle the result and error return from WKWebView,

You can initialize the webObject for JavaScript environment by calling:

import WebDomHandling

let webObject = WDWebObject()
webObject.delegate = self

Or yu can call initialize it with a source of JavaScript code and website URL:

let webObject = WDWebObject(
    forResource: "path/of/your/JavaScript-Code",
    url: "https://url/to/your/websites")

forResource doesn’t need js extension name.
You just need to type your filename.

Example: WDWebObject(forResource: "script")

You can also inherit it with the following code:

class ExampleWebObject: WDWebObject, WDWebObjectDelegate {
    
    override init() {
        super.init()
        
        delegate = self

        loadJavaScriptString(forResource: "script")
        load("https://url/to/your/websites")
    }

    // Protocol implementation.
    func webView(_ webView: WKWebView, didFinishEvaluateJavaScript result: String) {
        // handle result...
    }
    
    func webView(_ webView: WKWebView, didFailEvaluateJavaScript error: String) {
        // handle error...
    }
}

WDWebObjectDelegate

it has 2 functions:

• func webView(_ webView: WKWebView, didFinishEvaluateJavaScript result: String) for handling result return from WKWebView.
• func webView(_ webView: WKWebView, didFailEvaluateJavaScript error: String) for handling error return from WKWebView.

For example of delegate implementation, check Example.swift, this example shows how to implement delegation in SwiftUI.
