I have created an onSelection changed method as per the tutorial set out here: Selection Override
i have set this up for multi-selection as well which works well.
However when I try to deselect a group selected component it doesn't trigger the onSelectionChange event as I have it coded (shown below). The method is never triggered.
But if I comment out this line:
viewerApp.getCurrentViewer().select(idsToSelect);
Then the toggle of selected components works perfectly. And triggers the onSelectionChnge event.
Any help? Is there an alternative to doing methods after the slection has changed? Possibly when a part is clicked?
The code looks like this:
viewerApp.getCurrentViewer().addEventListener(Autodesk.Viewing.SELECTION_CHANGED_EVENT, onSelectionChanged);
function onSelectionChanged(data) {
console.log("selection changed event. Selected dbIds are: " + data.dbIdArray.toString());
if (data.dbIdArray.length > 0 && data.fragIdsArray.length > 0) {
var idsToSelect = [];
var selectionChanged = false;
for (var k = 0; k < data.dbIdArray.length; k++) {
var dbId = data.dbIdArray[k];
if (leafNodes.indexOf(dbId) > -1) {
dbId = viewerApp.getCurrentViewer().model.getData().instanceTree.nodeAccess.getParentId(dbId);
selectionChanged = true;
}
idsToSelect.push(dbId);
}
if (selectionChanged) {
viewerApp.getCurrentViewer().select(idsToSelect);
}
}
}

I have a function that hides a div with the corresponding ID based on a radio button change, however, I would like to hide multiple items at once and as ID is unique I am not able to just hide them all. How would I set up a class that I can hide and how would I adjust this code below to make that work?
Any help greatly appreciated
function onChangePackage() {
const nodes = document.getElementsByClassName("baseClass");
var selectedValue;
// Get selected radio
for (var i = 0, length = nodes.length; i < length; i++) {
if (nodes[i].checked) {
selectedValue = nodes[i].value;
break;
}
}
// Showing all nodes first
const nodePostFix = ['A','B','C'];
nodePostFix.forEach( node => {
const currentElement = elementsToHide.item(i);
if (currentElement.hasClass("hidden" + selectedValue)) {
currentElement.style.display = "none";
} else {
currentElement.style.display = "block";
}
});
};
You can use data attributes for this purpose together with the attribute selectors. So you need just to add the data-hidden-for attributes to the required nodes and access them using document.querySelector() or document.querySelectorAll()
First give all the elements a base class name baseClass. You could just give them a class name like hidden and then in your code you could do something like below:
const elementsToHide = document.getElementsByClassName("baseClass");
for (var i = 0; i < elementsToHide.length; i++) {
const currentElement = elementsToHide.item(i);
if (currentElement.hasClass("hidden")) {
currentElement.style.display = "none";
} else {
currentElement.style.display = "block";
}
}
And on the click event of the radio button you could add this class I mentioned above to whichever ones you want to hide:
element.classList.add("hidden");
or
element.classList.remove("hidden");
I have searched high and low and tried many different options from here, but i need a point in the right direction now :)
On this site:
http://www.michael-smith-engineers.co.uk
On the main nav, (in mobile view) if you click on Pumps, there should be further dropdown options, but i can not get this working. Any ideas would be appreciated.
I have tried adding the following script, without any luck...
<script>
// see whether device supports touch events (a bit simplistic, but...)
var hasTouch = ("ontouchstart" in window);
var iOS5 = /iPad|iPod|iPhone/.test(navigator.platform) && "matchMedia" in window;
// hook touch events for drop-down menus
// NB: if has touch events, then has standards event handling too
// but we don't want to run this code on iOS5+
if (hasTouch && document.querySelectorAll && !iOS5) {
var i, len, element,
dropdowns = document.querySelectorAll("#nav-site li.children > a");
function menuTouch(event) {
// toggle flag for preventing click for this link
var i, len, noclick = !(this.dataNoclick);
// reset flag on all links
for (i = 0, len = dropdowns.length; i < len; ++i) {
dropdowns[i].dataNoclick = false;
}
// set new flag value and focus on dropdown menu
this.dataNoclick = noclick;
this.focus();
}
function menuClick(event) {
// if click isn't wanted, prevent it
if (this.dataNoclick) {
event.preventDefault();
}
}
for (i = 0, len = dropdowns.length; i < len; ++i) {
element = dropdowns[i];
element.dataNoclick = false;
element.addEventListener("touchstart", menuTouch, false);
element.addEventListener("click", menuClick, false);
}
}
</script>
This script above is ridiculous for what i was trying so, tried this:
<script type="text/javascript">
function is_touch_device() {
return (('ontouchstart' in window) || (navigator.MaxTouchPoints > 0) || (navigator.msMaxTouchPoints > 0));
}
if(is_touch_device()) {
jQuery('.toggle-menu').on('click', function(){
jQuery(this).toggleClass('activate');
jQuery(this).find('ul').slideToggle();
return false;
});
}
</script>
</head>
Still no luck tho?!!!!
I'm using 2 comboboxes to filter a dataGrid that has been populated via csv file. The first combobox filters the columns and works fine:
//Listener and function for when the Agreement ID is selected
agreement_cb.addEventListener(Event.CHANGE, agreement);
function agreement(event:Event):void
{
//get the number of columns
var columnCount:Number = myGrid.getColumnCount();
for (var i:int=0; i<columnCount; i++)
{
myGrid.getColumnAt(i).visible = false;
}
var columnNumber:Number = agreement_cb.selectedItem.data;
myGrid.getColumnAt(columnNumber).visible = true;
myGrid.getColumnAt(0).visible = true;
myGrid.columns[0].width = 200;
}
But I can't find anything on how to get the same type of function to hide all of the rows except the one they select from the second drop-down (codes_cb).
Any help is appreciated...
UPDATE:
loadedData = myLoader.data.split(/\r\n|\n|\r/);
loadedData.pop();
for (var i:int=0; i<loadedData.length; i++)
{
var rowArray:Array = loadedData[i].split(",");
loadedData[i] = {"SelectAgreement":rowArray[0],"KSLTPROF0057":rowArray[1] .........};
}
loadedData.shift();
myGrid.columns = ["SelectAgreement", "KSLTPROF0057", ......];
import fl.data.DataProvider;
import fl.controls.dataGridClasses.DataGridColumn;
myGrid.dataProvider = new DataProvider(loadedData);
A DataGrid always shows all objects in its dataProvider, so to hide rows, you need to hide the data objects. Some classes that work as dataProviders have this functionality built in that makes this really easy (Any Class that implements IList can be operate as a dataProvider), however fl.data.DataProvider is not one of those classes.
So I will provide answers using both, if you can, I highly recommend using mx.collections.ArrayCollection over fl.data.DataProvider.
Section 1: fl.data.DataProvider
For this I'm assuming that your loadedData array is a class property, not declared in a function.
function agreement(event:Event):void
{
//your existing code here
var dataProvider:DataProvider = MyGrid.dataProvider as DataProvider;//recover the dataprovider
dataProvider.removeAll();//remove all rows
for (var x:int = 0; x<loadedData.length; x++)
{
if (loadedData[x] == "SELECTION MATCH") //insert here your selection criteria
{
dataProvider.addItem(loadedData[x]); //add it back into the dataProvider
}
}
}
function resetFilter():void
{
var dataProvider:DataProvider = MyGrid.dataProvider as DataProvider;//recover the dataprovider
dataProvider.removeAll(); //prevent duplication
dataProvider.addItems(loadedData);//reload all rows
}
Section 2: mx.collections.ArrayCollection
My reasoning for recommending this is because ArrayCollection already has the functions to do this without the risk of data being lost by objects losing scope, it also reduces the amount of code/operations you need to do. To do this we use ArrayCollection.filterFunction & ArrayCollection.refresh() to filter the "visible array" without changing the source.
private var dataProvider:ArrayCollection = new ArrayCollection(loadedData);
MyGrid.dataProvider = dataProvider;
function agreement(event:Event):void
{
//your existing code here
dataProvider.filterFunction = myFilterFunction;//use my filter
dataProvider.refresh();//refresh the visible list using new filter/sort
}
function resetFilter():void
{
dataProvider.filterFunction = null;//clear filter
dataProvider.refresh();//refresh the visible list using new filter/sort
}
function myFilterFunction(item:Object):Boolean
{
if (item == "SELECTION MATCH") return true;//insert your selection criteria here
else return false;
}
the filterFunction accepts a function and uses it to test each object in the ArrayCollection, the function has to return a Boolean, true for "Yes, display this object" and false for "Do not diplay".
My User has the following selection in his Gdoc.
Now from the sidebar he wants to to replace the selection he made on the document. The GAS question is if it is possible to do that at once, something like:
var selection = DocumentApp.getActiveDocument().getSelection()
selection.replace("newtext")
Or do I have to loop through selection.getRangeElements() in order to delete them (or replace them) and than in someway place the new text in that position?
Not, that's not possible (well, if it is, it's not documented).
You have to loop through the selected elements, mainly because the selection may take part of paragraphs, forcing you to manage that. i.e. deleting just the selected part. And for completed selected elements, you can just remove them entirely (like images).
Here's an implementation on how to do this (part of the Kaylan's Translate script modified by me to properly replace images and partially selected paragraphs.
function replaceSelection(newText) {
var selection = DocumentApp.getActiveDocument().getSelection();
if (selection) {
var elements = selection.getRangeElements();
var replace = true;
for (var i = 0; i < elements.length; i++) {
if (elements[i].isPartial()) {
var element = elements[i].getElement().asText();
var startIndex = elements[i].getStartOffset();
var endIndex = elements[i].getEndOffsetInclusive();
var text = element.getText().substring(startIndex, endIndex + 1);
element.deleteText(startIndex, endIndex);
if( replace ) {
element.insertText(startIndex, newText);
replace = false;
}
} else {
var element = elements[i].getElement();
if( replace && element.editAsText ) {
element.clear().asText().setText(newText);
replace = false;
} else {
if( replace && i === elements.length -1 ) {
var parent = element.getParent();
parent[parent.insertText ? 'insertText' : 'insertParagraph'](parent.getChildIndex(element), newText);
replace = false; //not really necessary since it's the last one
}
element.removeFromParent();
}
}
}
} else
throw "Hey, select something so I can replace!";
}
Problem description:
I have a table with three rows. The first row contains a drop down. When a user selects a drop down option, a new row should be generated beneath the current last row. How can I tweak this code to such that a new row is generated only when the user selects a drop down option of the current last row, and not any other row?
JSFiddle: http://jsfiddle.net/JPVUk/13/
var ViewModel = function() {
var self = this;
self.items = ko.observableArray([{comment:'first comment', amount:0}]);
self.addNewItem = function(){
self.items.push(new Item('',0));
};
}
var Item = function(comment, amount) {
var self = this;
self.comment = ko.observable(comment);
self.amount = ko.observable(amount);
};
vm = new ViewModel()
ko.applyBindings(vm);
What I am struggling to do:
So, since I want to bind the change event to the last row, here's how I am approaching it:
<select class="input-small" data-bind="items()[items.length-1] ? event: { change: $root.addNewItem }">
This is however not working. Any ideas folks ?
Can't you just past the row that causes the event to fire to your handler and check it there?
Something like this:
<select class="input-small" data-bind="event: { change: $root.addNewItem }">
And then:
self.addNewItem = function(row){
if (row == self.items()[self.items().length - 1]) {
self.items.push(new Item('',0));
}
};

I'm not sure if jQuery was acceptable so this just uses DOM. Basically use the event object passed to knockout. Traverse a little dom and determine is the event target is a child of the last row in the parent table:
var tableRow = event.target.parentNode.parentNode,
body = tableRow.parentNode,
nodes = body.childNodes,
children = [];
for (var i = 0; i < nodes.length; i++) {
// remove non-element node types. ie textNodes, etc.
if (nodes[i].nodeType === 1) {
children.push(nodes[i]);
}
}
if (tableRow === children[children.length - 1]) {
self.items.push(new Item('', 0));
}
