我用UIWebView加载了一个网页，这个网页中有按钮，点击后会弹出对话框

JavaScript中有三种形式的弹出框，alert，confirm，prompt；我只改掉了其中两种，最后那个prompt类型的捕捉不到，实在没找到资料，，求助各位大神帮忙！谢谢！！！

alert和confirm修改的代码如下、、希望对解决我的问题有所帮助！

@interface UIWebView (JavaScriptAlert) <UIAlertViewDelegate>

- (void)webView:(UIWebView *)sender runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WebFrame *)frame;

- (BOOL)webView:(UIWebView *)sender runJavaScriptConfirmPanelWithMessage:(NSString *)message initiatedByFrame:(WebFrame *)frame;

@end

@implementation UIWebView (JavaScriptAlert)

- (void)webView:(UIWebView *)sender runJavaScriptAlertPanelWithMessage:(NSString *)message initiatedByFrame:(WebFrame *)frame {

UIAlertView* customAlert = [[UIAlertView alloc] initWithTitle:@"Alert Title" message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];

[customAlert show];

[customAlert autorelease];

}

static BOOL diagStat = NO;

- (BOOL)webView:(UIWebView *)sender runJavaScriptConfirmPanelWithMessage:(NSString *)message initiatedByFrame:(WebFrame *)frame

{

UIAlertView *confirmDiag = [[UIAlertView alloc] initWithTitle:@"Confirm Title" message:message delegate:self cancelButtonTitle:NSLocalizedString(@"Cancel", @"Cancel") otherButtonTitles:NSLocalizedString(@"OK", @"OK"), nil];

[confirmDiag show];

while (confirmDiag.hidden == NO && confirmDiag.superview != nil)

[[NSRunLoop mainRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.01f]];

[confirmDiag release];

return diagStat;

}

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

{

if (buttonIndex == 0)

{

diagStat = NO;

}

else if (buttonIndex == 1)

{

diagStat = YES;

}

@end
