I have a simple form, and I work with a button that has a handler to get the submit. When the user clicks that button, I want to show a 'DIV'-element.
How is it possible to show / hide a specific element in Sencha?
Thanks in advance!
To show a component:
Ext.getCmp('YourDivID').show();
To hide a component:
Ext.getCmp('YourDivID').hide();
Before this, you have to of course create a component with YourDivID.
You have to use getCmp in order to select an element,
but you have to use Ext.select() in order to select an HTML element like divs.
Example usage:
Ext.select("#yourdiv").hide();

Can someone help me out here on how to add passengers count dropdown form like on the image below. i have been searching all over but cannot seem to find any demo or help.
thanks for your help
This is a solution using pure HTML, CSS, and jQuery. For a Bootstrap-specific answer, How use input field as toggle for bootstrap 4 dropdown may help.
Moving on.
You should create a normal number type form and add a disabled attribute in the input tag so that no cursor appears when you click the form (<input type="number" disabled>). Then, just create a dropdown menu (probably a <div> with an absolute position right under the input) with a classname of your choice (assuming in this answer that you choose .passengerInput as the classname).
You can hide the dropdown by default using the $(".passengerInputDropdown").hide() method in the body of your JS.
Then, when you click the form, using the $(".passengerInput").toggle() method, do something to the effect of:
$(".passengerInput").on("click", () => {
$(".passengerInputDropdown").toggle();
})
Let me know if this helps!
Hi I am working on a Angular4 application and for UI I am using Primeng.
I have a multi-select element which behaves pretty much the same as it does over here https://www.primefaces.org/primeng/#/multiselect
The only thing I want different is on the drop-down, when "X" (close) button is clicked, I want it to clear all the selection instead of closing the drop-down itself.
Is there any way to achieve that in primeng ?
Help is appreciated !
You can manually trigger the checkbox in the left by jquery.
declare var jquery:any;
declare var $ :any;
$('.ui-chkbox-box.ui-widget.ui-corner-all.ui-state-default').trigger('click')
or you make the value of the p-multiselect equal to [].
Ex.
//html
<p-multiSelect #multiselect>
<button type="button" (click)="functionToClear(multiselect)"</button>
</p-multiselect>
//ts
functionToClear(multiselect): void {
multiselect.value = [];
}
It isn't possible, but you can clear all the selection by clicking the checkbox in the left corner twice.
While it isn't a supported functionality of the Multiselect PrimeNg component, if you really want it to do that, you would have to manually edit the component, multiselect.js, and modify the close(event) function to do what you want.
you can use formGroup and try to clear value following way:
html:
<ng-multiselect-dropdown [(ngModel)]="data"
[data]="fetchedData" [settings]="customeSettings"
formControlName="myControl">
</ng-multiselect-dropdown>
.ts:
this.form_name.controls.myControl.setValue("");
normally the multi-select input in primeng is binded to a property that holds the selected members, usually an array.
you can use a reset button for example that when clicked, it will empty that propery/array and this will clear all the selected check boxes of the multi-select.
Since PrimeNg version 13, you can use [showClear]="true" property to display an 'X' icon next to the control value.
I want to track clicks on the following button/link with Google Tag Manager. I created a trigger in Google Tag Manager that triggers when the element_id = 100. This works fine, except that when I click exactly on the text, it doesn't do anything, the link looks like a button, with the text in the middle of it. I can't change anything to the html or css, otherwise I can think of multiple things, so I need to find a solution without changing the html. Also, the 'myclass' class and the 'label' class get used in other elements.
<a class="myclass" id="100" href="http://www.url.com">
<span class="label">Text</span>
</a>
Anyone an idea?
Thanks a lot,
The following workaround worked:
Create trigger when element text contains "Text". This will trigger events on the button and the label on the button, of all buttons with "Text" as label.
Create tag for that trigger that checks with simple javascript if either the id of the current element = 100, which will happen when you click the button but not the label, or that the id of the parent = 100, which happens when you click the label. You can get the element that triggered the tag using the built-in variable "Click Element". Which you need to access the parent element.
Technically, you shouldn't have a CSS ID that starts with (or is) a number, so not sure if your code example is accurate or not. Whatever the case, you're probably better off using "matches CSS selector" so that you don't need to use any custom JS.
If indeed your HTML uses id="100", then the above will work. If it's anything else that doesn't start with a number, then you can use
#whatever > span
Link to form
The form can be found at the link above.
Up until this morning the radio buttons and the form had been working as expected, however now users can't change their answer once they've picked from one of the two radio buttons even though they use the same input name. Using $("#volunteer-form input:radio[name='gender']:checked").val() I've found that the value is being correctly set and that the two buttons are still linked by a common name. Also, it appears possible to switch between the two using a bit of jQuery, like so:
$("#volunteer-form input[name=gender][value=male]").prop('checked', true);
Any ideas?
its because of your javascript block here:
$(document).ready(function() {
$('.inline').fancybox({
'maxWidth': 600
});
$('.form').click(function(event){
event.preventDefault();
});
});
when you are clicking on the radio button inside the form your preventDefault is stopping the change of radiobutton state ... or maybe you already knew that.
What is the intended purpose of including the preventDefault where you have it?
I am using the drop down in webpage and also the submit button to submit the selected value of the drop down.but i don't want to use the submit button. when i select the value from drop down it should re direct the page without using the submit button. can anyone post the code... i was using select and option tag.
See Navigational pulldown menus in HTML for a comprehensive guide, but in a nutshell:
Bind an onchange JavaScript event handler to the select element that calls the forms submit() method
Don't do this, it is a horrible UI.
You need to use JavaScript to perform this operation.
For example, in jQuery, you could do something similar to:
$(function() {
$('#myDropDownId').change(function() {
$('#formId').submit();
});
});
JQuery:
$('#selectId').change(function(){
if ($(this).val())
$(this).closest('form').submit();
});
If you don't want to use jQuery, you can do this with Javascript. Change your select box to look like this.
<select name="NAME" onchange="this.form.submit();">
