I have a code to add additional rows to my #moo textarea:
$('#moo').focus(function(){
$(this).attr('rows', '4');
});
So when I focus the textarea gets higher. Is there any way to animate it? (css transition seems to fail this one).
Use the height and transition css attributes.
textarea {
height: 50px;
transition: 1s
}
<textarea onclick="event.target.style.height=120px">

I'm trying to customize mat-select with multiple checkboxes.
for some reason the panel get wrong min-width as below:
and I don't know where its calculating this min-width.
also I tried to add panelClass and override the min-width from this class,
for example:
<mat-select #multipleSelect (selectionChange)="selectItem($event.value)" panelClass="multiple-panel" multiple>
&.multiple-panel {
min-width: 200px !important;
}
but when opening the dropdown its open with the original width (like in the pic) and after few millisecond"jump" to the custom min-width defined on the panel class.
I find the mat-select very hard to style. anybody knows how to solve this problem?
You can style your mat-select dialog box by giving a panel class (as you mentioned).
Please follow this demo : https://stackblitz.com/edit/angular-matselect-style?file=src/styles.css
to see the styled mat-select components.
Reason :
Reason for the delay is that angular for dialog-boxes, create a cdk-overlay-pane inside the cdk-overlay-container container, So in case of mat-select it provides a min-width of 180px, which is overridden by our panel class in the slight delay.
Yes, there is a slight delay in opening of dialog box and customizing its width to the specified width provided in the panel class. But the delay is acceptable in the project that i was working on. So, you can find the demo for styling the mat-select component, as i have provided 2 components and you can modify any css properties.
Try to use styles using ::ng-deep or :host >>>, if not finding any luck, please paste the styles in style.css.
Update 1 :
Tried css animations, and opacity for making smooth opening of the mat-select options.
.panel-class-applied-on-mat-select {
animation-name: opacityDelay !important;
animation-duration: 0.3s !important;
}
#keyframes opacityDelay {
0% {opacity: 0;}
25% {opacity: 0;}
50% {opacity: 0;}
75% {opacity: 0;}
100% {opacity: 1;}
}
Updated StackBlitz Demo
I used another approach.
Just added this piece of code to global style.
.mat-select-panel {
// some your code
&.ng-animating {
visibility: hidden;
}
}
You can try this solution on
DEMO StackBlitz.
Hack with opacity did not fix jumping width when select is closing.
You'll need to change viewEncapsulation to none at your component decorator.and then add following css to remove the transition effect.Have a look at viewencapsulation in angular docs https://angular.io/guide/component-styles#view-encapsulation.
#Component({
selector: 'app-selector',
templateUrl: './template.html',
styleUrls: ['./template.css'],
encapsulation: ViewEncapsulation.None
})
//CSS
.cdk-overlay-connected-position-bounding-box .cdk-overlay-pane .mat-select-panel.ng-animating {
display: none;
}
Try this way : define a panel class for your mat-select in the code and then in the global/app styling file just add:
.panel-class-name .mat-select-panel {
// add your styling here
}
It worked for me to add some component specific styling for material components.
Please go easy on me S.O. This is my first time contributing. :)
After debugging the console, and running into this issue. Solutions were not clear online. So I'm posting mine here in case someone else runs into this.
I found that there is a width permanently set for the infix class. If you unset it, and optionally add some padding to the right of the value, you'll find that will resolve the issue. Add :host for encapsulation when using ::ng-deep.
Important to Note: ::ng-deep is being permanently deprecated after Angular v14.
There is a property in the #Component() annotation called encapsulation which can be used to turn off the view encapsulation for the component instead of using ::ng-deep.
Solution for the deprecation of ::ng-deep:
#Component({
selector: 'app-selector-name',
template: `<div>Hello World!</div>`,
encapsulation: ViewEncapsulation.None,
styles: [
`
:host mat-form-field .mat-form-field-infix {
width: unset;
}
:host mat-form-field .mat-select-value {
padding-right: 0.5rem; /* 8px */
/* Alternatively, for TailwindCSS: #apply pr-2 */
}
:host .random-class {
/* some encapsulated styling... */
}
.another-random-class {
/* some non-encapsulated styling... */
}
`
]
})
Solution if you do not care about the deprecation of ::ng-deep:
:host ::ng-deep mat-form-field .mat-form-field-infix {
width: unset;
}
:host ::ng-deep mat-form-field .mat-select-value {
padding-right: 0.5rem; /* 8px */
}
I'm trying to use the md-chips directive of angular material in a single line, but when I add more chips than size of a field, the field add a line to bottom like in this image.
I think you need a CSS workaround to adapt the behaviour of md-chips in an input form.
For example you can use this CSS:
/* reduce input element (not visible till the user begins editing) width */
.md-chips .md-chip-input-container input {
max-width: 20px;
}
/* adapt input to md-chip height */
.myheight {
height: 49px !important;
}
/* adapt datepicker input to md-chip height */
.md-datepicker-input {
height: 49px;
}
Here is a demo: http://codepen.io/beaver71/pen/gPqPBW
P.S.: don't forget that docs declare:
Warning: This component is a WORK IN PROGRESS. If you use it now, it will probably break on you in the future.
Is there a way to modify the Twitter 'follow' button to display the number of followers in a bubble but hide the word "followers"? I basically want my 'follow' button to look the same as the 'tweet' button.
The current code looks like this:
<a href="https://twitter.com/User" class="twitter-follow-button" data-show-count="true"
data-show-screen-name="false" data-dnt="true">Follow #User</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id))
{js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";
fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
I had this same issue and solved it by basically hiding the word 'followers' and creating a fake right edge to the bubble, if that makes sense. So, you have to wrap the button in its own div, then hide the overflow of that div and set the width to the exact point where the word disappears and the height precisely to the height of the button you are using. Here's a code example:
#titter-div {
border-radius: 4px; /* to mimic the curved edges of the count box */
border-right: 1px solid #AAAAAA; /* this is the width and color of the count box border */
height: 20px; /* this height works for the medium button */
width: 88px; /* precise width to hide the word */
overflow: hidden; /* actually hides the word */
}
This worked for me to create exactly what you are looking for. Hope this helps.
To display the number of followers in a bubble but hide the word "followers", here is the code I use with an iframe :
<iframe
src="//platform.twitter.com/widgets/follow_button.html?screen_name=Vacance_Luberon&show_screen_name=false"
style="width: 88px; height: 20px;"
allowtransparency="true"
frameborder="0"
scrolling="no">
</iframe>
My particular problem is that I want the autocomplete function to not have round corners, but all the other widgets that have round corners should.
Is there a parameter I can pass to disable the corners just for the autocomplete?
Edit
Let's see if this can be answered.
On page Datepicker.
I'd like to remove all round-corner classes from appearing (the header and the next-previous buttons).
$( "#datepicker" ).datepicker('widget').removeClass('ui-corner-all'); would not work.
Very late but here it goes:
jQuery UI widgets have a method, which returns the HTML node for the widget itself.
So the answer would be:
$('#someinput').autocomplete(...).autocomplete('widget').removeClass('ui-corner-all');
Responding to the EDIT:
As far I can see, you need to chain widget() method with autocomplete() (or datepicker()) method for it to work. Seems like it doesn't work for regular HTML nodes returned by $().
assign this css class to the element with corners of your widget.
.ui-corner-flat {
border-top-left-radius: 0px !important;
border-top-right-radius: 0px !important;
border-bottom-left-radius: 0px !important;
border-bottom-right-radius: 0px !important;
}
$("#elementwithcorners").addClass("ui-corner-flat");
to remove the bottom left radius
in the constructor I did this
$( "#signup" ).dialog(
{
create: function (event, ui) {
$(".ui-dialog").css('border-bottom-left-radius','0px');
},
}
);
The _suggest() method of the Autocomplete widget calls menu.refresh(), and therefore resets the ui-corner-all class for menu items, etc., each time the input changes. However, the open() callback is called after every menu.refresh() call within _suggest(), and so is a sensible place to adjust classes as desired:
$("#autocomplete").autocomplete("option", {
open: function(event, ui) {
$(this).autocomplete("widget")
.menu("widget").removeClass("ui-corner-all")
.find(".ui-corner-all").removeClass("ui-corner-all");
}
});
The Datepicker widget is a little tougher, as it's built to be sort of a semi-singleton. Here we need a monkey patch to do it consistently, since none of the supplied callback options is suitable:
// store the built-in update method on the "global" instance...
$.datepicker.__updateDatepicker = $.datepicker._updateDatepicker;
// ...and then clobber with our fix
$.datepicker._updateDatepicker = function(inst) {
$.datepicker.__updateDatepicker(inst);
inst.dpDiv.removeClass("ui-corner-all")
.find(".ui-corner-all").removeClass("ui-corner-all");
};
Note that the default _updateDatepicker() implementation has no return value. Also, note that the _updateDatepicker() method is not an interface method, so should not be assumed to be available. As such, the most consistent way to accomplish the corner fix is with appropriate CSS, along the lines of:
.ui-autocomplete.ui-menu.ui-corner-all,
.ui-autocomplete.ui-menu .ui-menu-item > a.ui-corner-all,
.ui-datepicker.ui-corner-all,
.ui-datepicker-header.ui-corner-all,
.ui-datepicker-next.ui-corner-all,
.ui-datepicker-prev.ui-corner-all {
border-radius: 0;
}
More specificity (or the !important directive) may be used to ensure these selectors are respected. This is exactly why jQuery uses theme classes – fudging these things in is an interesting hack, but it's the less clean option unless style is unavailable…
Create a new CSS class for the element you don't want rounded corners.
p.rounded { border-radius: 10px; }
p.none-rounded { border-radius: 0; }
I am still pretty "green" when it comes to web development and javascript/jQuery programming, so any help is appreciated. Here is what I want to do.
I want to do the same thing that a jQuery UI dialog box does where it puts a semi-transparent image over the entire page and disables clicking of any of the controls underneath.
I want to know how I might put some kind of spinner overlay on top to show that the website is working in the background. If I can use a animated GIF file that would be fine, but I'm not quite sure on the best approach to this.
Here is an example of the grayed-out effect with a dialog box:
jQuery UI Example. I want to know how to produce this effect without the dialog box on top. I do not have a good example of the spinner behavior.
All suggestions, website referrals, and code is appreciated.
EDIT: I do not mean a "spinner control". I will try to find an example of what I am thinking of by spinner.
EDIT: What I mean by "spinner" is a loading gif of some kind like the "Indicator Big" gif on this website: http://ajaxload.info/
I always like to use the jQuery BlockUI plugin:
http://malsup.com/jquery/block/
Check out the demos, you'll probably find something you're looking for there.
One way to do it is to have a div that is hidden by default and has properties to set the background colour to a grey (#666 for instance) and its transparency set to something like 0.8.
When you want to display use jQuery to get the size of the screen/browser window, set the size of your div and display it with a high zindex, so it displays on top. You can also give this div your spinner gif graphic (no repeat, and centered).
Code:
#json-overlay {
background-color: #333;
opacity: 0.8;
position: absolute;
left: 0px;
top: 0px;
z-index: 100;
height: 100%;
width: 100%;
overflow: hidden;
background-image: url('ajax-loader.gif');
background-position: center;
background-repeat: no-repeat;
}
Only things to watch out for are select elements in IE6, as these will show through the div, so you can either use jQuery bgframe to solve that, or what I have done in the past is just hide select elements when displaying the div and showing them again when hiding your div
Why don't you just use "modal:true"?
$(function () {
$("#dialog").dialog($.extend({}, dialogOptions, {
autoOpen: false,
width: 500,
modal: true,
show: {
effect: "blind",
duration: 1000
},
hide: {
effect: "fade",
duration: 1000
}
}));
$("#profile_edit").click(function () {
$("#dialog").dialog("open");
});
$("#save_and_close").click(function () {
$("#dialog").dialog("close");
});
});
You can use something like this jquery code. Pass the id of the element that you want to stay on top of the page:
function startModal(id) {
$("body").prepend("<div id='PopupMask' style='position:fixed;width:100%;height:100%;z-index:10;background-color:gray;'></div>");
$("#PopupMask").css('opacity', 0.5);
$("#"+id).data('saveZindex', $("#"+id).css( "z-index"));
$("#"+id).data('savePosition', $("#"+id).css( "position"));
$("#"+id).css( "z-index" , 11 );
$("#"+id).css( "position" , "fixed" );
}
function stopModal(id) {
if ($("#PopupMask") == null) return;
$("#PopupMask").remove();
$("#"+id).css( "z-index" , $("#"+id).data('saveZindex') );
$("#"+id).css( "position" , $("#"+id).data('savePosition') );
}
you can use simple div and then ajaxstart and ajaxstop event
<div id="cover"></div>
$('#cover')
.hide()
.ajaxStart(function () {
$(this).fadeIn(100);
})
.ajaxStop(function () {
$(this).fadeOut(100);
});
