[ACCEPTED]-Getting iPhone GO button to submit form-keyboard

So, here was our specific issue:

We had a 10 form with multiple user input fields, but 9 not a true <input type="submit"> (it was being submitted via 8 JS).

As such, the GO button did nothing.

We 7 then added an <input type="submit"> and set it to display: none hoping that 6 would do the trick. Nope. Didn't work.

On 5 a whim, we changed display: none to margin-left: -1000px

That 4 worked!

Apparently, Safari is looking for 3 the presence of a SUBMIT button in the form 2 and only if it's not display: none, it will 1 then fire it when you hit the GO button.

If there are more than one inputs and you 1 want to hide the submit, the best seems:

<input type="submit" style="visibility:hidden;position:absolute"/>

You can also bind a keypress listener to 3 the element or form. The iphone "Go" button 2 is the same as the enter button on a computer, char 1 13.

$('someElem').bind("keypress", function(e){
    // 'Go' key code is 13
    if (e.which === 13) {
       console.log("user pressed Go");
       // submit your form with explicit JS.
    } 
 });

I could not work out why a very simple google 5 maps form was not submitting using the iPhone 4 Go button.

Turns out, after stripping it 3 down, it does not work with target="_blank" on the form 2 tag.

Removed that, and now the Go button 1 works on iPhone.

Here's a JSFiddle to try it

The code given by the others is correct. If 2 you are using jQuery Mobile then add

data-role="none" 

to 1 the submit input element. Like so:

<input type="submit" data-role="none" style="visibility: hidden; position: absolute;" />

As of writing (11/19/2019), on iOS 13.1.3, the 5 following scenarios change the return key label:

• The INPUT element must be wrapped in a FORM element, and the FORM element must have an action attribute. (It can be an empty string, i.e. action="".)
• If the INPUT element has a type of search, the return key have a label of search.
• Any other value for the type attribute will result in the return key having a label of go.

The 4 presence of an INPUT or BUTTON element with a type set 3 to submit does not appear to affect the return 2 key label. (Though it's a good idea to include 1 one for accessibility purposes.)

Just enclosing my input type='search' in 3 a form tag did the trick when I encountered 2 this problem. Hopefully it might help others 1 that had this problem as well.

Here's the submit button style that worked 2 for me, with minimum side-effects on the 1 page:

.... style="width: 0px ; height: 0px" ....

GO button to submit is a default behaviour 5 of iOS and don`t try to hack the keyboard 4 because UIKeyboard is runtime header, however 3 you can inject JS for your html in runtime 2 and prevent GO button behaviour (GO acts 1 like a Enter key),

Try this,

    WKWebView *webView;  
    WKUserContentController *contentController = [[WKUserContentController alloc] init];

    NSString *script1 = @"var isEnter = false;";
    WKUserScript *userScript1 = [[WKUserScript alloc] initWithSource:script1 injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:false];
    [contentController addUserScript:userScript1];

    NSString *script2 = @"function captureGoKey(e){if(isEnter){e.preventDefault();}isEnter = false;}";
    WKUserScript *userScript2 = [[WKUserScript alloc] initWithSource:script2 injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:false];
    [contentController addUserScript:userScript2];

    NSString *script3 = @"var form = document.getElementsByTagName('form')[0];";
    WKUserScript *userScript3 = [[WKUserScript alloc] initWithSource:script3 injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:false];
    [contentController addUserScript:userScript3];

    NSString *script4 = @"document.onkeypress = function(e){if(e.keyCode == 13){isEnter = true;}}";
    WKUserScript *userScript4 = [[WKUserScript alloc] initWithSource:script4 injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:false];
    [contentController addUserScript:userScript4];

    NSString *script5 = @"if(form.attachEvent){form.attachEvent('submit', captureGoKey);}else{form.addEventListener('submit', captureGoKey);}";
    WKUserScript *userScript5 = [[WKUserScript alloc] initWithSource:script5 injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:false];
    [contentController addUserScript:userScript5];

    WKWebViewConfiguration *config = [[WKWebViewConfiguration alloc] init];
    config.userContentController = contentController;

    webView = [[WKWebView alloc] initWithFrame:self.view.bounds configuration:config];
