iOS webview 和 js 互動
1.先上一段 html 程式碼
<html>
<head>
<meta http-equiv="Content-Type"content="text/html; charset=utf8">
</head>
<body>
<h1>這是一段內容</h1>
<input type="button"value="測試"onclick="check()" />
<input type="button"value="測試2"onclick="check2()"/>
</body>
</html>
2. js 程式碼
function loadURL(url) {
var iFrame;
iFrame = document.createElement("iframe");
iFrame.setAttribute("src", url);
iFrame.setAttribute("style", "display:none;");
iFrame.setAttribute("height", "0px");
iFrame.setAttribute("width", "0px");
iFrame.setAttribute("frameborder"
document.body.appendChild(iFrame);
// 發起請求後這個iFrame就沒用了，所以把它從dom上移除掉
iFrame.parentNode.removeChild(iFrame);
iFrame = null;
}
function check() {
loadURL("lichongyang:abc");
}
function check2() {
loadURL("lichongyang2:abc");
}
3.當js 呼叫 iOS 的時候 通過上面的js 程式碼 會重定向一個 請求的url 在
- (BOOL
NSURL * url = [request URL];
if ([[url absoluteString] rangeOfString:@"abc"].location!= NSNotFound) {
UIAlertView * alertView = [[[UIAlertViewalloc] initWithTitle:@"test"message:[url absoluteString] delegate:nilcancelButtonTitle:@"OK"otherButtonTitles:nil] autorelease];
[alertView show];
return NO;
}
//獲取當前頁面的title
//self.title ＝ [webView stringByEvaluatingJavaScriptFromString:@"document.title"];
return YES;
}
