How to click dijit.form.Button programmatically - dojo

I have form and input inside.
<input type="submit" label="Upload" data-dojo-type="dijit.form.Button" data-dojo-attach-point="leftLogoSubmit" id="leftLogoSubmit"/>
Is it possible push this button programmatically?
I tried
this.leftLogoSubmit.onclick();
but it not works.
Uncaught TypeError: this.leftLogoSubmit.onclick is not a function

You need to use on.emit().
It can be done in 2 ways:
As #tik27 stated:
dijit.registry.byId("leftLogoSubmit").emit('click', { cancelable:true, bubbles: true})
Note the 2 properties on the object. Without this, the click will not work properly.
You can also do:
on.emit(dojo.byId("leftLogoSubmit"), 'click', { cancelable:true, bubbles: true})
Where on is required as dojo/on
Last but not least, you can call the onClick method of the button directly (like #frank proposed):
dijit.registry.byId("leftLogoSubmit").onClick();
Difference is:
- in 1st case the widget is use to access the emit method (only works with Evented widgets)
- in 2nd case dojo/on is used so we need to pass the button domNode instead of the widget
- in 3rd it is not a native click (so will not bubble). It just call the button click handler

You can write like this
this.leftLogoSubmit.on("click", function() {
// Your code
});

you can fire the click function as.
this.leftLogoSubmit.onClick();
note: the capital C in the onClick.

You can go with core JavaScript solution
document.getElementById("leftLogoSubmit").click();

How to stop click propagation when clicking on a leaflet popup?

I have a popup in a leaflet map that can be closed by clicking on the 'x' in its upper right corner. How do I make the click event not propagate to the map itself?
I've tried using preventPropagate() in many places and forms, but none of them seem to work.
My latest code looks like that:
<div class="actions" #click="stopPropagation($event)">
(...)
stopPropagation(e) {
e.stopPropagation()
}
The above div (.actions) is the popup's main div.
I have also tried calling the function at a click in the popup's component tag in the parent component, but the result was the same, meaning clicking the 'x' closes the popup as expected but also results in a click event in the map that lies behind.
I use Vue and vue2-leaflet.
I appreciate any insight from you guys. Thanks!
UPDATE: actually, doesn't matter where in the popup the click happens, it always gets propagated to the map behind.
So, for reference, here's my solution:
<div class="actions" #click="someMethod($event)">
(...)
someMethod(e) {
(... some code)
return false
}
The command 'return false' is what solved my problem.
I tried using '#click.stop', but it gives me the '$event.stopPropagation() is not a function' error. The same happens if I run 'e.stopPropagation()' from inside the function.
The accepted answer didn't work for me so I wrapped my l-map in a div and applied the click.stop to that.
<div #click.stop.prevent.self="">
<l-map...>
</div>
It seems to me that the actual click event is parsed by the leaflet library rather than the Vue-compatible vue-2-leaflet, so the event that is received by the function doesn't have stopPropagation or preventDefault methods on the object. Thus, when Vue calls them with .stop or .prevent, the JS engine throws an error.
This is what I figured out for my issue dealing with event handling and stopping the propagation.
e.g.
someReference.on("click", (evt: L.LeafletEvent) => {
// You don't try to reference the event (evt) that is passed in
L.DomEvent.stopPropagation; // Just call this and it kills the propagation
// or you can call
// L.DomEvent.preventDefault(evt);
...
})
Could try an event modifier
Perhaps the stop modifier:
<div class="actions" #click.stop="closePopup">

How to stop event propagation on calling a function on change of mat-checkbox?

<mat-checkbox (change)="handleProductClick(children, $event)" [(ngModel)] = "children.selected"
[name]="children.grpId" [id]="children.id"></mat-checkbox>
handleProductClick(selectedProd : Product, event: any)
{
event.stopPropagation();
}
If I use click function instead of change it works fine. Although I can't use click. I have to stick with change. Is there a way to call stopPropagation from change function? If not what else can I do to stop the event propagation?
I got it working. Had to use both click and change on the checkbox. I had tried that earlier. The only difference was I was calling a function in the click method and it never got called. If you call $event.stopPropagation on click method in the template, it works well. strange. The below answer solved my problem. Angular 2 prevent click on parent when clicked on child
<mat-checkbox (change)="handleProductClick(children, $event)"[checked]="children.selected" (click)="$event.stopPropagation()"
[name]="children.grpId" [id]="children.id"></mat-checkbox>

how to hide dojo validation error tooltip?

I'm using dojo to validate input fields and if there is an error (for eg: required field) it appears in the dojo tooltip. But, I would like to show error in the custom div instead of tooltip.
So, I'm wondering if there is a way to hide/disable the validate error to appear in the tooltip? If so, I can capture the error message shown in the hidden tooltip and show the result in custom div, which will be consistent with error styling across the application.
Please advise. Thanks.
I would recommend to use the standard Dojo validation mechanism, contrary to what vivek_nk suggests. This mechanism works great in most cases, and covers most situations (required, regular expressions, numbers, dates etc.).
To solve your issue: you can overrule the "dispayMessage" function of a ValidationTextBox (for example).
displayMessage: function(/*String*/ message){
// summary:
// Overridable method to display validation errors/hints.
// By default uses a tooltip.
// tags:
// extension
if(message && this.focused){
Tooltip.show(message, this.domNode, this.tooltipPosition, !this.isLeftToRight());
}else{
Tooltip.hide(this.domNode);
}
}
Just create your own ValidationTextBox widget, extend dijit/form/ValidationTextBox, and implement your own "displayMessage" function.
Simple solution for this scenario is not to add the "required" condition at all to those fields. Instead add a separate event handler or function to check for this validation.
For eg: add a function for onBlur event. Check if the field is a mandatory. If so, show message in the custom div as expected.
<input data-dojo-type="dijit/form/TextBox"
id="sampleText" type="text" mandatory="true" onBlur="checkMandatory(this)"/>
function checkMandatory(field) {
if(field.mandatory=='true' && field.value=="") {
alert('value required'); // replace this code with my showing msg in div
} else {
field.domNode.blur();
}
}
This above code snippet does not use Dojo for validation, rather manual. Dojo actually helps to ease this by just adding the attribute "required". If that is not required, then just ignore Dojos help for this case and go native.
So, for all fields, just add the attributes - "mandatory" & "onBlur", and add the above given function for onBlur action for all these fields.

how to attach an event to dojox.mobile.heading 'back' button

In addition to the 'back' button functioning as expected, I need to asynchronously invoke a function to update some db tables and refresh the UI.
Prior to making this post, I did some research and tried the following on this...
<h1 data-dojo-type="dojox.mobile.Heading" id="hdgSettings" data-dojo-props="label:'Settings',back:'Done',moveTo:'svStart',fixed:'top'"></h1>
dojo.connect(dijit.registry.byId("hdgSettings"), "onclick",
function() {
if (gblLoggerOn) WL.Logger.debug(">> hdgSettings(onclick) fired...");
loadTopLvlStats();
});
Since my heading doesn't have any other widgets than the 'back' button, I thought that attaching this event to it would solve my problem... it did nothing. So I changed it to this...
dojo.connect(dijit.registry.byId("hdgSettings")._body, "onclick",
function() {
if (gblLoggerOn) WL.Logger.debug(">> hdgSettings(onclick) fired...");
loadTopLvlStats();
});
As it turns out, the '._body' attribute must be shared by the Accordion widget that I just happen to use as my app's main UI component, and any attempt to interact w the Accordion rendered my entire app useless.
As a last resort, I guess I could simply forgo using the built-in 'back' button, and simply place my own tabBarButton on the heading to control my app's transition and event processing.
If the community suggests that I use my own tabBarButton, then so be it, however there has to be a way to cleanly attach an event to the built-in 'back' button support.
Thoughts?
The following should do the trick:
var backButton = dijit.registry.byId("hdgSettings").backButton;
if (backButton) {
dojo.connect(backButton, "onClick", function() { ... });
}
Remarks:
The code above should be executed via a dojo/ready call, to avoid using dijit's widget registry before it gets filled. See http://dojotoolkit.org/reference-guide/1.9/dojo/ready.html.
Note the capitalization of the event name: "onClick" (not "onclick").
Not knowing what Dojo version you use (please always include the Dojo version information when asking questions), I kept your pre-AMD syntax, which is not recommended with recent Dojo versions (1.8, 1.9). See http://dojotoolkit.org/documentation/tutorials/1.9/modern_dojo/ for details.

Dynamic menu button items in TinyMCE

I have a custom menubutton in my tinyMCE editor that uses specific HTML elements elsewhere on the page as the menu items. I use a jQuery selector to get the list of elements and then add one each as a menu item:
c.onRenderMenu.add(function(c,m) {
m.add({ title: 'Pick One:', 'class': 'mceMenuItemTitle' }).setDisabled(1);
$('span[data-menuitem]').each(function() {
var val = $(this).html();
m.add({
title: $(this).attr("data-menuitem"),
onclick: function () { tinyMCE.activeEditor.execCommand('mceInsertContent', false, val) }
});
});
});
My problem is that this only happens once when the button is first clicked and the menu is first rendered. The HTML elements on the current page will change occasionally based on user clicks and some AJAX, so I need this selector code to run each time the menu is rendered to make sure the menu is fully up-to-date. Is that possible?
Failing that, is it possible to dynamically update the control from the end of my AJAX call elsewhere in the page? I'm not sure how to access the menu item and to update it. Something using tinyMCE.activeEditor.controlManager...?
Thanks!
I found a solution to this problem, though I'm not sure it's the best path.
It doesn't look like I can make tinyMCE re-render the menu, so instead I've added some code at the end of my AJAX call: after it has updated the DOM then it manually updates the tinymce drop menu.
The menu object is accessible using:
tinyMCE.activeEditor.controlManager.get('editor_mybutton_menu')
where mybutton is the name of my custom control. My quick-and-dirty solution is to call removeAll() on this menu object (to remove all the current menu items) and then to re-execute my selector code to find the matching elements in the (new) DOM and to add the menu items back based on the new state.
It seems to work just fine, though tweaks & ideas are always welcome!
