    $(".select-embed-code").each(function(){setEmbedCode($(this));});
    }
    </script>

我需要使用 webview 的 stringByEvaluatingJavaScriptFromString 方法获取var con, var idm的值。

请帮忙

你可以使用类似的东西

NSString *scriptString = [webView stringByEvaluatingJavaScriptFromString: 
                           @"document.getElementsByTagName('script')[0].innerHTML"];

获取 javascript。

之后，一种可能性是使用正则表达式来获取您请求的变量：

NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"var con =\"(\\w*)\";"
                                                                       options:NSRegularExpressionCaseInsensitive
                                                                         error:&error];
NSArray *matches = [regex matchesInString:scriptString
                                  options:0
                                    range:NSMakeRange(0, [scriptString length])];
// The capture group would be at index '1'
if ([matches count] > 0 && [matches[0] rangeAtIndex:1].location != NSNotFound) {
    NSLog(@"%@", [scriptString substringWithRange:[matches[0] rangeAtIndex:1]]);
}

有关更多选项和可能性，请查看文档。
