ios - How do I edit the HTML in a UIWebView? -

-

i have uiwebview loads html. how access html elements , change them?

i want like: webview.gethtmlelement(id: main-title).value = "new title"

if want edit in form, how can it:

- (void)webviewdidfinishload:(uiwebview *)webview {    nsstring *evaluate = [nsstring stringwithformat:@"document.form1.main-title.value='%@';", @"new title"];    [webview stringbyevaluatingjavascriptfromstring:evaluate]; }

or if not in form, maybe (untested):

- (void)webviewdidfinishload:(uiwebview *)webview {    nsstring *evaluate = [nsstring stringwithformat:@"document.getelementbyid('main-title').value='%@';", @"new title"];    [webview stringbyevaluatingjavascriptfromstring:evaluate]; }

note! assume editable field want change. otherwise talking parsing , concept works this:

    static bool firstload = yes;      - (void)webviewdidfinishload:(uiwebview *)webview {         if (firstload) {             firstload = no;             nsstring *html = [_webview stringbyevaluatingjavascriptfromstring:@"document.documentelement.outerhtml"];             //edit html here, parsing or similar.             [webview loadhtmlstring:html baseurl:[[nsbundle mainbundle] resourceurl]];         }     }

you can read more parsing here: objective-c html parser

mysql - FireDac error 314 - but DLLs are in program directory -

-
i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
