Programmatically Fire Button Click Event

Programmatically fire button click event?

Sort of like Ken's answer, but more flexible as it'll keep track of the buttons actual actions if you change them or add more than one.

[button sendActionsForControlEvents:UIControlEventTouchUpInside];

Trigger button click event programmatically using JavaScript or jQuery on page load in Internet Explorer

You can try like this:

$(document).ready(function(){
$('#btnFilter').trigger('click');
});

$(document).on('click','#btnFilter',function(e){
btnFilter(e);
});

function btnFilter(e)
{
element = e.currentTarget.parentElement;
}

Programmatically fire button click event

I figured out a solution after a few hours of searching:

POST(EVENT:Accepted, ?ResetInput)

Please post any other answer if there's a more correct way of doing this.


Here's the info regarding the POST function from the Clarion help docs:

POST( event [,control] [,thread] [,position] )

event: An integer constant, variable, expression, or EQUATE containing an event number. A value in the range 400h to 0FFFh is a User-defined event.

control: An integer constant, EQUATE, variable, or expression containing the field number of the control affected by the event. If omitted, the event is field-independent.

thread: An integer constant, EQUATE, variable, or expression containing the execution thread number whose ACCEPT loop is to process the event. If omitted, the event is posted to the current thread.

position: An integer constant, EQUATE, variable, or expression containing either zero (0) or one (1). If one (1), the event message is placed at the front of the event message queue. If omitted or zero (0), the event message is placed at the end of the event message queue.

POST posts an event to the currently active ACCEPT loop of the specified thread. This may be a User-defined event, or any other event. User-defined event numbers can be defined as any integer between 400h and 0FFFh. Any event posted with a control specified is a field-specific event, while those without are field-independent events.

POSTing an event causes the ACCEPT loop to fire but does not cause the event to "happen." For example, POST(EVENT:Selected,?MyControl) executes any code in EVENT:Selected for ?MyControl but does not cause ?MyControl to gain focus.

Example:

Win1 WINDOW('Tools'),AT(156,46,32,28),TOOLBOX
BUTTON('Date'),AT(0,0,,),USE(?Button1)
BUTTON('Time'),AT(0,14,,),USE(?Button2)
END

CODE
OPEN(Win1)
ACCEPT

! Detect user-defined event:
IF EVENT() = EVENT:User THEN BREAK END

CASE ACCEPTED()
OF ?Button1
POST(EVENT:User,,UseToolsThread) !Post field-independent event to other thread
OF ?Button2
POST(EVENT:User) ! Post field-independent event to this thread
END
END

CLOSE(Win1)

You can try this one also:

programmatically trigger a button click

A click on Button means execution of set of instructions.
I would suggest you to write the button.onClick instructions in a method like:

void codeToBeImplemented(){
//Your Logic
}

and then calling this method on button click or programmatically when needed.

Calling the method on Button click:

enemy_left.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v)
{
codeToBeImplemented();
}
});

Calling the method programmatically anywhere, In your case in

if(bida1<kontra1){
codeToBeImplemented();
}

How to fire click event of panel programmatically?

Your panel's Click event is going to be attached to an event handler, right?

Then just call that event handler from the button's click event handler:

public void Panel1_Click(object sender, EventArgs e)
{
//Do whatever you need to do
}

public void Button1_Click(object sender, EventArgs e)
{
//Do anything you need to do first
Panel1_Click(Panel1, EventArgs.Empty);
}

The effect will be the same as clicking on the panel.

How to manually trigger click event in ReactJS?

You could use the ref prop to acquire a reference to the underlying HTMLInputElement object through a callback, store the reference as a class property, then use that reference to later trigger a click from your event handlers using the HTMLElement.click method.

In your render method:

<input ref={input => this.inputElement = input} ... />

In your event handler:

this.inputElement.click();

Full example:

class MyComponent extends React.Component {
render() {
return (
<div onClick={this.handleClick}>
<input ref={input => this.inputElement = input} />
</div>
);
}

handleClick = (e) => {
this.inputElement.click();
}
}

Note the ES6 arrow function that provides the correct lexical scope for this in the callback. Also note, that the object you acquire this way is an object akin to what you would acquire using document.getElementById, i.e. the actual DOM-node.

Programmatically trigger click event of button on Android

I figured it out myself by looking at the source code of ionic-angular. In the file node_modules/ionic-angular/tap-click/tap-click.js is a method that handles the click event. It calls another method called shouldCancelClick(ev) which returns true when this.dispatchClick is undefined or false. this.dispatchClick is set by pointerStart(ev) which is bound to the mousedown event.

So all that has to be done is to trigger a mousedown event before triggering the click event.

I solved it like this:

var e1 = document.createEvent('MouseEvents');
e1.initEvent('mousedown', true, true);
focusedButton.dispatchEvent(e1);

var e2 = document.createEvent('MouseEvents');
e2.initEvent('click', true, true);
focusedButton.dispatchEvent(e2);
