Add button to fancytree node to delete/remove that node? - fancytree

I cannot find an example to do this anywhere, although I could have sworn I've seen one in the past.
I want to add a button to a node in fancytree so that either on hovering over that node (or maybe on selecting it) the button displays (a white x on a red circle, for example) and clicking it will delete/remove that node. At all other times the delete button should be hidden for the node.
I've been unable to find any kind of example where a custom link or button is added to a fancytree node though - maybe it's not possible to do or I'm just using the wrong search terms?
Edit: I found a way to add a clickable button by appending html to the title string:
title: component.name() + "<span class='deleteButton'><a href='#' data-bind='click: myfunction'><img src='../../Content/images/deleteIcon.png' /></a></span>",
And by adding some custom css to my site file:
span.fancytree-node span.deleteButton {
display: none;
}
span.fancytree-active span.deleteButton {
margin-left: 10px;
display: inline-block;
}
But this adds the button to the title text and is therefore subject to the highlighting of the title when active. It would be better if there was a way to add this to the node OUTSIDE of the title text. Is that possible Martin?

$("#tree").fancytree({
source: [...],
renderNode: function (event, data) {
var node = data.node;
var $nodeSpan = $(node.span);
// check if span of node already rendered
if (!$nodeSpan.data('rendered')) {
var deleteButton = $('<button type="button" class="btn">delete node</button>');
$nodeSpan.append(deleteButton);
deleteButton.hide();
$nodeSpan.hover(function () {
// mouse over
deleteButton.show();
}, function () {
// mouse out
deleteButton.hide();
})
// span rendered
$nodeSpan.data('rendered', true);
}
}
});

I normally use css ':after' for such cases (https://developer.mozilla.org/de/docs/Web/CSS/::after).
If that is not enough, you can always tweak the markup in the 'renderNode' event.

tooltip's aren't "centered" despite direction: center being set

I'm creating labels for polygons with the following code:
L.marker(polygon.getBounds().getCenter())
.bindTooltip('County Name', {permanent: true, direction: 'center'})
.addTo(mymap);
However, the result isn't exactly what I'd call centered. Like the majority of the tooltip is on the right side of the marker whereas I'd expect the marker to be smack dab in the middle of the tooltip.
Any ideas as to what I can do to improve the situation?
If I can get this working I'll hide the marker by doing {opacity: 0} but if I do that now it'll look off center without a frame of reference.
If you want to add labels to the polygon you can use instead customised Tooltip.
In your Javascript code :
let custom_popup = L.popup()
.setLatLng(polygon.getBounds().getCenter())
.setContent('County name')
.addTo(map);
Then you can customise to make it look like a Marker using CSS :
.leaflet-popup-close-button // we remove the X to close the popup
{
display: none;
}
.leaflet-popup-tip // We remove the arrow pointing at the coordinates
{
display: none;
}
.leaflet-popup-content // We center the text inside the Tooltip
{
text-align: center;
}
Here's the result :

Setting the class of a particular element permanently from the group of elements created using foreach binding in knockout js

I just started using knockout js. I am creating group of images using foreach binding of knockout js. Initially all the images have same css class "imageUnvisited" and I am trying to change and set the class(permanently) of the particular image that I click to show the visited state. I am successful in changing the class on click event but as soon as I click on another image, the new added class of the previously clicked image gets remove. I am new it the IT filed so pardon me if you find anything wrong, please help.
Below is the code that I am using:
var vm = {
item: jsonData.items,
clickedImageIndex: ko.observable('')
}
ko.applyBindings(vm);
function getVisitedClass(data, index) {
if (index() == vm.clickedImageIndex()) {
return "imageVisited"
}
}
function imageClicked(data, e) {
var itemTarget = e.target || e.srcElement;
index = ko.contextFor(itemTarget).$index();
vm.clickedImageIndex(index);
}
.imageUnvisited {
border: solid 1px green;
}
.imageVisited {
border: solid 1px black;
}
<div data-bind="foreach: item" id="image_gallery">
<div id="image_wrapper">
<image data-bind="attr: { id: 'image' + $index(), src: $data.Src, class: getVisitedClass($data, $index)},click: imageClicked" class="imageUnvisited" role="button"></image>
</div>
</div>
Why your current code doesn't work:
You're storing one index in clickedImageIndex which is updated on every click. Therefore, the expression index() == vm.clickedImageIndex() can only be true for one image at a time.
A "quick fix":
Instead of storing an index in clickedImageIndex, you can store multiple inside an object.
In your vm:
clickedImageIndex: ko.observable({})
In your handler:
var clicked = vm.clickedImageIndex();
clicked[index] = true;
vm.clickedImageIndex(clicked);
In your getVisitedClass:
if (vm.clickedImageIndex()[index()]) {
return "imageVisited"
}
A better fix:
It's probably a good idea to follow knockouts MVVM architecture a bit stricter... This means:
Map your images to ImageViewModel instances
Add a clicked observable property to ImageViewModel
Add a ImageViewModel.prototype.onClick method that sets this.clicked(true)
Use the data-bind="click: onClick, css: { 'imageVisited': clicked }" data-bind to update state.

Ag-grid RowStyle with selected row

I am using ag-grid 5.1.2
I've configured a getRowStyle function to set the background-color for certain items.
I've noticed that has overridden the 'selected row' color now, so when a row is selected the background will not change to indicate as such.What is the correct way to still let highlighted row color work with the custom getRowStyle. Here is the typescript for the rowStyle function:
self.customRowStyle = function (params: AgParams) {
if (!params.data.isShaded) {
return {
"background-color": "#CEDDDD",
};
}
return null;
};
In your CSSyou can choose not to target the selected row.
ag-Grid adds the class onto the row that is returned from your getRowStyle callback
It also adds .ag-row-selected for rows that get selected.
You can simply use CSS to only target not selected rows or even apply a different style to the rows that are both selected and have your custom class.
Here is an example:
CSS
.bg-red.ag-row:not(.ag-row-selected) {
background-color: red ;
}
OR different style for both selected and bg-red
.bg-red.ag-row {
background-color: red;
}
.bg-red.ag-row.ag-row-selected {
background-color: pink;
}
JS
rowClassRules: {
'bg-red': () => {
return true; // applies class bg-red to all rows
},
},
Here is a live running code example of this in action.
Also here is another live example that overrides row styles on click of a button, but this doesn't involve styling callbacks:
Is this what you are looking for?
Use the getRowClass gridOption instead of getRowStyle. Then in CSS set the appropriate styles for your background row and the brackground row when highlighted.

How to disable default 'Click to edit' on Jeditable?

I'm using the jeditable plugin for making some values editable. I noticed that when a value is empty the default text 'Click top edit' appears which I don't want. But I still want to make that field editable too. How to manage this?
I noticed a suggestion at http://www.datatables.net/forums/discussion/5865/jeditable-and-default-click-to-edit/p1, but that does not seem to work - at least not for me; when using the placeholder : "" the field is not editable anymore.
My related code:
$('.edit').editable('edit_save.php', {
cancel : 'Cancel',
submit : 'OK'
});//$('.edit').editable('jeditable_save.php', {
Without any text to fill it, the editable element needs to be an inline block with height and width like this:
.edit {
border: 1px solid red;
display: inline-block;
min-height: 20px;
min-width: 100px;
}
and set a blank placeholder like you mentioned:
$('.edit').editable(function (value, settings) {
return value;
}, {
cssclass: 'editing',
placeholder: '',
});
See this fiddle http://jsfiddle.net/chrisdillon/37JqF/
I tried add this row: placeholder:'
&
nbsp;' and it works.
If you can add this row, you see your input is empty.
$('.edit').editable('Something', {
something,...
placeholder:' ',
})

sort multiple items at once with jquery.ui.sortable

did somebody manage to sort multiple items at once with jquery.ui.sortable?
we are working on a photo managing app.
select multiple items
drag them to a new location.
thanx
I had a similar requirement, but the solution in the accepted answer has a bug. It says something like "insertBefore of null", because it removes the nodes.
And also i tried jQuery multisortable, it stacks the selected items on top of each other when dragging, which is not what i want.
So I rolled out my own implementation and hope it will save others some time.
Fiddle Link.
Source code:
$( "#sortable" ).sortable({
// force the cursor position, or the offset might be wrong
cursorAt: {
left: 50,
top: 45
},
helper: function (event, item) {
// make sure at least one item is selected.
if (!item.hasClass("ui-state-active")) {
item.addClass("ui-state-active").siblings().removeClass("ui-state-active");
}
var $helper = $("<li><ul></ul></li>");
var $selected = item.parent().children(".ui-state-active");
var $cloned = $selected.clone();
$helper.find("ul").append($cloned);
// hide it, don't remove!
$selected.hide();
// save the selected items
item.data("multi-sortable", $cloned);
return $helper;
},
stop: function (event, ui) {
// add the cloned ones
var $cloned = ui.item.data("multi-sortable");
ui.item.removeData("multi-sortable");
// append it
ui.item.after($cloned);
// remove the hidden ones
ui.item.siblings(":hidden").remove();
// remove self, it's duplicated
ui.item.remove();
}
});
There's a jQuery UI plugin for that: https://github.com/shvetsgroup/jquery.multisortable
jsFiddle: http://jsfiddle.net/neochief/KWeMM/
$('ul.sortable').multisortable();
... or just define a 'items' option to your multisortable that way (for example) :
$('table tbody').multisortable({
items: 'tr'
});
you can use shvetsgroup/jquery.multisortable
but it will create problem.. because, that js is designed only for tags...
but customize it to use it, its very simple i'll tell you how????
at first download that .js and use it in your program...
step 1. open the js file...now edit the following lines...
$.fn.multiselectable.defaults = {
click: function(event, elem) {},
mousedown: function(event, elem) {},
selectedClass: 'selected',
items: 'li'
};
the above are lines from 107 to 112....
there you can see "items: 'li'
in that use your tag which you are used to enclose those image like if you are using, or or anything you are using like this
$.fn.multiselectable.defaults = {
click: function(event, elem) {},
mousedown: function(event, elem) {},
selectedClass: 'selected',
items: 'div' // or any tag you want...
};
and 249 to 254
selectedClass: 'selected',
placeholder: 'placeholder',
items: 'li'
};
}(jQuery);
change the line " item:'li' " with your tag like this
selectedClass: 'selected',
placeholder: 'placeholder',
items: 'div' // or anything else
};
}(jQuery);
if you are working on textboxes inside those envelopes.. you have to get rid of these lines too
// If no previous selection found, start selecting from first selected item.
prev = prev.length ? prev : $(parent.find('.' + options.selectedClass)[0]).addClass('multiselectable-previous');
var prevIndex = prev.index();
after that comment line...
add a line code that search textbox or check box or any interaction element inside it...
like this..
// If no previous selection found, start selecting from first selected item.
item.children("input").focus(); // customize this code to get your element focus...
prev = prev.length ? prev : $(parent.find('.' + options.selectedClass)[0]).addClass('multiselectable-previous');
var prevIndex = prev.index();
and also to indicate selected tags or elements... use styles like this
div { margin: 2px 0; cursor: pointer; }
div.selected { background-color: orange }
div.child { margin-left: 20px; }
actually i used div.. instead of that you can use any tag you wish...
hope will help u.... if it is not... read again.. and ask again....
