How to change the icon of a node dynamically based on an event.
The below code will loop through all child nodes after a lazy load, and change the child's icon (if the child is a node and not a folder). The renderTitle() is important here, as this tells the node to be redrawn and show the new icon. This can be applied to any other event type.
$("#tree").fancytree({
source: {
url: "/your/source/url"
},
lazyLoad: function(event, data) {
data.result = {
url: "/your/lazyload/url"
};
},
loadChildren: function(event, data) {
var children = data.node.getChildren();
for (var i = 0; i < children.length; i++) {
if (!children[i].isFolder()) {
children[i].data.icon = "/your/icon.png";
children[i].renderTitle();
}
}
}
});

Lines and polygons are added without problems, but when trying to add markers on top of a polygon layer ("lyrPoly"), it interprets that I want to click on the polygon (e.g. opens popup) instead of adding marker. How can I avoid this? I am using leaflet.pm to add markers, linestrings and polygons.
This is the code for the marker:
map.on('pm:create', function(e) {
e.marker;
var type = e.layerType,
layer = e.layer;
$(document).ready(function() {
var jsnMarker = layer.toGeoJSON().geometry;
jsnMarker = {
type: "MultiPoint",
coordinates: [jsnMarker.coordinates]
};
})
});
$(function() {
$('.check').change(function() {
var data = $(this).val();
if (data == "versionOne") {
var markerStyle = {
draggable: false,
icon: customIcon,
};
var options = {
markerStyle,
}
map.pm.enableDraw('Marker', options);
} else if (data == "versionTwo") {
var markerStyle = {
draggable: false,
icon: otherIcon,
};
var options = {
markerStyle,
}
map.pm.enableDraw('Marker', options);
}
$('.check').trigger('change');
});
And inside the ajax function I use this:
lyrMarker = L.geoJSON(jsnMarker, {
pointToLayer: function (feature, latlng) {
if(feature.properties.marker_type=="versionOne"){
return L.marker(latlng, {
icon: customIcon
})
}else if
(feature.properties.marker_type=="versionTwo"){
return L.marker(latlng, {
icon: otherIcon
})
} ,
onEachFeature: forEachMarker
});
For the polygon-layer I have a corresponding "onEachFeature"-function that looks like this:
function forEachFeature(feature, layer) {
var att = feature.properties;
var popupContent =
"Popup-content" ;
layer.bindPopup(popupContent, {
offset: [0, -120]
});
layer.on("click", function (e) {
lyrPoly.setStyle(style); //resets layer colors
layer.setStyle(highlight); //highlights selected.
});
};
Adding marker to the background/basemap works fine, but not onto the polygon layer. Why is that, and what would be a good solution? I don't want to add the marker to the same layer as the polygons, but avoid polygons "getting in the way".
I've had ideas about making the polygon layer interactive: false while in adding-marker-mode, but haven't succeeded.
Update your click event and test if drawing mode is enabled:
function forEachFeature(feature, layer) {
var att = feature.properties;
var popupContent =
"Popup-content" ;
layer.bindPopup(popupContent, {
offset: [0, -120]
});
layer.on("click", function (e) {
if(!map.pm.Draw.Marker.enabled()){
lyrPoly.setStyle(style); //resets layer colors
layer.setStyle(highlight); //highlights selected.
}
});
};
Update
To disable the popup open event add following code at the top of your file. Before you create a Layer with a Popup:
L.Layer.include({
_openPopup: function (e) {
var layer = e.layer || e.target;
//This IF is new
if(map.pm.Draw.Marker.enabled()){
return;
}
if (!this._popup) {
return;
}
if (!this._map) {
return;
}
// prevent map click
L.DomEvent.stop(e);
// if this inherits from Path its a vector and we can just
// open the popup at the new location
if (layer instanceof L.Path) {
this.openPopup(e.layer || e.target, e.latlng);
return;
}
// otherwise treat it like a marker and figure out
// if we should toggle it open/closed
if (this._map.hasLayer(this._popup) && this._popup._source === layer) {
this.closePopup();
} else {
this.openPopup(layer, e.latlng);
}
},
});

I need to display two numbers in my StandardTile. The data source is a SOAP web service, which I had to call twice with different parameters to obtain these two numbers. Is there any way to fill the tile with these two figures? I tried creating one XMLModel per each ajax call to the web service, and then binding the property of the control to the node from the response, but I'm just getting the same figure duplicated.
Below is my onInit method in the controller
onInit: function () {
// callback from ajax request
SOAPRequester.getMessageOverview(function (data) {
var oModel = new sap.ui.model.xml.XMLModel();
oModel.setData(data);
var oStandardTile = sap.ui.getCore().byId("__xmlview0--messageOverviewTile");
if (oStandardTile !== undefined) {
oStandardTile.setModel(oModel, "overview");
oStandardTile.bindProperty("number", {
path: "/SOAP-ENV:Body/rpl:getMessageListResponse/Response/rn5:number",
model: "overview"
});
}
});
//callback from the second ajax call
SOAPRequester.getErrorMessages(function (callbackData) {
var oModel = new sap.ui.model.xml.XMLModel();
oModel.setData(callbackData);
var oStandardTile = sap.ui.getCore().byId("__xmlview0--messageOverviewTile");
if (oStandardTile !== undefined) {
oStandardTile.setModel(oModel, "overview");
oStandardTile.bindProperty("infoState", "Error");
oStandardTile.bindProperty("info", {
path: "/SOAP-ENV:Body/rpl:getMessageListResponse/Response/rn5:number",
model: "overview"
});
}
});
},
Yes, it is. You are using the same model name twice, thus the firs one is not visible anymore. Simply use different model name, i.e. "overview" and "overview2" or what ever you prefer:
onInit: function () {
// callback from ajax request
SOAPRequester.getMessageOverview(function (data) {
var oModel = new sap.ui.model.xml.XMLModel();
oModel.setData(data);
var oStandardTile = sap.ui.getCore().byId("__xmlview0--messageOverviewTile");
if (oStandardTile !== undefined) {
oStandardTile.setModel(oModel, "overview");
oStandardTile.bindProperty("number", {
path: "/SOAP-ENV:Body/rpl:getMessageListResponse/Response/rn5:number",
model: "overview"
});
}
});
//callback from the second ajax call
SOAPRequester.getErrorMessages(function (callbackData) {
var oModel = new sap.ui.model.xml.XMLModel();
oModel.setData(callbackData);
var oStandardTile = sap.ui.getCore().byId("__xmlview0--messageOverviewTile");
if (oStandardTile !== undefined) {
oStandardTile.setModel(oModel, "overview2");
oStandardTile.bindProperty("infoState", "Error");
oStandardTile.bindProperty("info", {
path: "/SOAP-ENV:Body/rpl:getMessageListResponse/Response/rn5:number",
model: "overview2"
});
}
});
},
Hint: You could also improve your code a little, i.e.
call this.getView().byId("messageOverviewTile") or if you have the right UI5 version this.byId("messageOverviewTile") instead of sap.ui.getCore().byId("__xmlview0--messageOverviewTile")
Do the binding for your controls in your view and then in onInit() call this.getView().setModel(oModel, "overview") and this.getView().setModel(oModel, "overview2")
I am new in vuejs2 development. I am working in a modal development. I kept the modal body code in a component and displaying that modal in another component. I have below code in modal body component.
<script>
import SemanticModal from 'vue-ya-semantic-modal'
export default {
components: { SemanticModal: SemanticModal() },
name: 'ModalBody',
props: ['active1',],
data() {
return {
visible: false
}
},
methods: {
close() {
this.$emit('sendValue', false); //this is working
this.visible = false
},
open () {
this.visible = true
},
},
watch: {
active1 () {
if (this.active1 && !this.visible) this.open()
else if (!this.active1 && this.visible) this.close()
},
},
directives: {
'click-outside': {
bind: function(el, binding, vNode) {
el.onclick = function(e) {
var modal = document.getElementsByClassName("modal");
el.addEventListener('click', function (event) {
if (!modal[0].contains(event.target)) {
vNode.context.$emit('sendValue', false); //this is not working
this.visible = false
}
})
}
}
}
}
}
I am calling that model (child) component in parent component like below
<modal-body :active1="active1" #sendValue="active1 = $event"></modal-body>
I need to change the below props active1 value to false from child to parent component.
You are handling click event by using directives.
According to your requirement , clickoutside directive should emit sendValue event from child to parent. But i feel like your code has some complications.
The proper code to accomplish your scenario is below
directives: {
'clickoutside': {
bind: function(el, binding, vNode) {
el.onclick = function(e) {
console.log("binding clicked");
vNode.context.$emit('sendValue', false);
}
}
}
}
if your objective is to use click event you can use #click binding to accomplish the same
I have to show only selected nodes and parents, and hide rest nodes.
There is no get_unchecked in current documentation. My json format is huge so taking it in string and formatting and reloading tree will be inefficient.
Is there a way to get all unchecked nodes and hide it?
if there is i can check all parent node of current checked node and then just hide all unchecked nodes, but i cannot find any method to retrive all unchecked nodes.
You can do it by:
getting all selected nodes along with the parents
going over all nodes and seeing if a node is not selected, then hiding it
Check code below and demo - codepen.
var $tree = $("#myTree").jstree(),
nodesSelected = $('#myTree').jstree('get_checked', true),
nodeIdsToStay = [];
nodesSelected.forEach(function(node) {
var path = $tree.get_path(node, false, true);
path.forEach(function(n) {
if (nodeIdsToStay.indexOf(n) === -1) {
nodeIdsToStay.push(n);
}
})
})
$('#myTree').find('li').each(function() {
if (nodeIdsToStay.indexOf(this.id) === -1) {
$(this).hide();
}
})
Work around for the question i made.
$('#jstree_demo_div').on('loaded.jstree', function(e, data) {
console.log("loaded");
checked_ids = $('#jstree_demo_div').jstree('get_selected', true);
$("#jstree_demo_div").jstree('select_all');
$.each(checked_ids, function(index, value) {
$("#jstree_demo_div").jstree('deselect_node', value);
uiParentsShow(value);
});
checked_ids = $('#jstree_demo_div').jstree('get_selected', true);
$.each(checked_ids, function(index, value) {
$("#jstree_demo_div").jstree('hide_node', value);
});
});
function uiParentsShow(node) {
try {
var parent = $("#jstree_demo_div").jstree('get_parent', node);
$("#jstree_demo_div").jstree('deselect_node', parent);
if (parent != '#') {
uiParentsShow1(parent);
}
} catch (err) {
console.log('Error in uiGetParents' + err);
}
}
Steps:
Step 1: Selecting All the elements
Step 2: Deselecting the checked node and the parent of checked node
Step 3: Hide Selected Nodes
From the response above I was able to create this function that filters the Treeview based on a node attribute value. (Replace '
$('#jstree').find('li').each(function () {
if ($("#" + this.id).attr("tag") == "<MYTAG>") {
$(this).hide();
}
else {
$(this).show();
}
})
I wrote another code maybe help someone.
var value = $(this).val();
if (value == "all") {
$('#permissions').jstree("show_all")
return;
}
checkedNodes = $('#permissions').jstree("get_checked", true);
if (value == "granted") {
$('#permissions').jstree("hide_all")
checkedNodes.forEach(function (node) {
$('#permissions').jstree("show_node", node.parent);
$('#permissions').jstree("show_node", node);
});
}
else if ("notgranted") {
$('#permissions').jstree("show_all")
checkedNodes.forEach(function (node) {
$('#permissions').jstree("hide_node", node);
});
}
I could not found any examples with this scenario so here we go:
I want the user choose a directory, load all files inside it, change them, and save this file overriding it or saving a new file in that same directory without asking where he want to save.
I don't know how to list the files of the directory
I don't know how to save a file in a directory without prompting the filechooser window
I believe it is possible because I see something similar here (last paragraph):

Any answer will be appreciated, Thank you
EDIT: Thanks to Chris Johnsen for giving me this great answer:
var fileHandler = function() {
var _entry = null;
this.open = function(cb) {
chrome.fileSystem.chooseEntry({
type: 'openDirectory'
}, function(dirEntry) {
if (!dirEntry || !dirEntry.isDirectory) {
cb && cb(null);
return;
}
_entry = dirEntry;
listDir(_entry, cb);
});
};
this.save = function(filename, source) {
chrome.fileSystem.getWritableEntry(_entry, function(entry) {
entry.getFile(filename, {
create: true
}, function(entry) {
entry.createWriter(function(writer) {
writer.onwrite = function() {
writer.onwrite = null;
writer.truncate(writer.position);
};
writer.write(new Blob([source], {
type: 'text/javascript'
}));
});
});
});
};
this.saveAs = function(filename, source) {
chrome.fileSystem.chooseEntry({
type: 'openDirectory'
}, function(entry) {
chrome.fileSystem.getWritableEntry(entry, function(entry) {
entry.getFile(filename, {
create: true
}, function(entry) {
entry.createWriter(function(writer) {
writer.onwrite = function() {
writer.onwrite = null;
writer.truncate(writer.position);
};
writer.write(new Blob([source], {
type: 'text/javascript'
}));
});
});
});
});
};
var listDir = function(dirent, cb, listing) {
if (listing === undefined) {
listing = [];
}
var reader = dirent.createReader();
var read_some = reader.readEntries.bind(reader, function(ents) {
if (ents.length === 0) {
return cb && cb(listing);
}
var process_some = function(ents, i) {
for (; i < ents.length; i++) {
listing.push(ents[i]);
if (ents[i].isDirectory) {
return listDir(ents[i], process_some.bind(null, ents, i + 1), listing);
}
}
read_some();
};
process_some(ents, 0);
}, function() {
console.error('error reading directory');
});
read_some();
};
};
Your save method should work fine (mostly, see below) for your second requirement (write to a code-chosen filename without another user prompt), but there are a couple of bugs in open (at least as presented in the question):
Inside the chooseEntry callback, this !== fileHandler because the callback is invoked with a different this (probably the background page’s window object).
You can work around this in several ways:
Use fileHandler instead of this (if you are not using it as any kind of prototype).
Use .bind(this) to bind each of your callback functions to the same context.
Use var self = this; at the top of open and use self.entry (et cetera) in the callbacks.
You may want to call cb for the success case. Maybe you have another way of postponing calls to (e.g.) fileHandler.save (clicking on some element to trigger the save?), but adding something like
⋮
cb && cb(self.entry);
⋮
after self.entry = dirEntry makes it easy to (e.g.) chain open and save:
fileHandler.open(function(ent) {
fileHandler.save('newfile','This is the text\nto save in the (possibly) new file.');
});
There is a latent bug in save: if you ever overwrite an existing file, then you will want to call writer.truncate() (unless you always write more bytes than the file originally held).
⋮
writer.onwrite = function() {
writer.onwrite = null;
writer.truncate(writer.position);
};
writer.write(…);
⋮
It looks like you have a good start on the file listing part. If you want to reference the list of files later, then you might want to save them in your object instead of just logging them; this can get a bit hairy if you want to recurse into subdirectories (and also not assume that readEntries returns everything for its first call).
function list_dir(dirent, cb, listing) {
if (listing === undefined) listing = [];
var reader = dirent.createReader();
var read_some = reader.readEntries.bind(reader, function(ents) {
if (ents.length === 0)
return cb && cb(listing);
process_some(ents, 0);
function process_some(ents, i) {
for(; i < ents.length; i++) {
listing.push(ents[i]);
if (ents[i].isDirectory)
return list_dir(ents[i], process_some.bind(null, ents, i + 1), listing);
}
read_some();
}
}, function() {
console.error('error reading directory');
});
read_some();
}
You could use it in the open callback (assuming you add its success callback) like this:
fileHandler.open(function(ent) {
ent && list_dir(ent, function(listing) {
fileHandler.listing = listing;
console.log('listing', fileHandler.listing.map(function(ent){return ent.fullPath}).join('\n'));
fileHandler.save('a_dir/somefile','This is some data.');
});
});
