如何在uiwebview页面中查找文本并将其突出显示并使用swift转到文本在页面中的位置?
例如chrome查找文本:
search example
但是我改用警报视图:
my search example in my app !!!
最佳答案
这是快速代码:
1)将UIWebViewSearch.js文件添加到您的项目中
func highlightAllOccurencesOfString(str:String) -> Int {
let path = Bundle.main.path(forResource: "UIWebViewSearch", ofType: "js")
var jsCode = ""
do{
jsCode = try String(contentsOfFile: path!)
}catch
{
// do something
}
self.newsWebView.stringByEvaluatingJavaScript(from: jsCode)
let startSearch = "uiWebview_HighlightAllOccurencesOfString('\(str)')"
self.newsWebView .stringByEvaluatingJavaScript(from: startSearch)
let result = self.newsWebView.stringByEvaluatingJavaScript(from: "uiWebview_SearchResultCount")
return Int(result!)!
}
func scrollTo(index:Int) {
self.newsWebView.stringByEvaluatingJavaScript(from: "uiWebview_ScrollTo('\(index)')")
}
func removeAllHighlights() {
self.newsWebView.stringByEvaluatingJavaScript(from: "uiWebview_RemoveAllHighlights()")
}
