How can I inject javascript into a webview (IOS/Swift) after loading some custom html.
加载一些自定义 html 后，如何将 javascript 注入 webview（IOS/Swift）。
@IBOutlet weak var webView: UIWebView!
var html = "<div id='test'></div>"
self.webview.loadHTMLString(html, baseURL: nil)
I want to inject the following javascript into the webview after I load my custom html.
我想在加载自定义 html 后将以下 javascript 注入到 webview 中。

Just do:
做就是了：
let js = "var myelement = document.getElementById(\"test\");myelement.innerHTML= \"New Text\";"
webView.evaluateJavaScript(js, completionHandler: nil)
If you are using UIWebViewinstead of WKWebView, do this:
如果您使用的是UIWebView代替WKWebView，请执行以下操作：
let js = "var myelement = document.getElementById(\"test\");myelement.innerHTML= \"New Text\";"
_ = webView.stringByEvaluatingJavaScript(from: js)

use WKWebview and use WKNavigationDelegateDelegate
使用 WKWebview 并使用 WKNavigationDelegate委托
func webView(webView: WKWebView, didFinishNavigation navigation: WKNavigation!) {
let str = "setData(\"\(uid)\",\"\(DataProvider.sharedInstance.baseUrl)\")"
self.webView.evaluateJavaScript(str) { (id, error) in
print(error)
}
}
