I'm trying to render a graph to its original state from a saved JSON object that stores the nodes and edges arrays and all of their respective data including the x,y positions. I have an onLoad function that gets triggered when the page loads:
const onLoad = (_core) => {
core.current = _core;
if (savedView.nodes && savedView.node != undefined) {
let curElements = JSON.stringify({
nodes: savedView.nodes;
edges: savedView.edges;
});
let layout = core.current._cy.layout({ name: 'preset' });
layout.run();
core.current._cy.add(JSON.parse(curElements));
In the above code snippet, _core is the core cytoscape graph object that's being passed into the function and the 'savedView' var is an object that contains the nodes and edges arrays that I want to pull out to use when re-rendering the graph. A sample of a couple of the elements contained in the nodes array:
{
classes: 'draft-entity'
data: {
id: 'rkb1'
type: 'person'
displayName: 'Bob'
elementType: 'node'
{
grabbable: true
group: "nodes"
locked: false
pannable: false
position: {x: 334.85120850976364, y: 20}
removed: false
selectable: true
selected: false
}
{
classes: 'draft-entity'
data: {
id: 'rkb2'
type: 'person'
displayName: 'Jane'
elementType: 'node'
{
grabbable: true
group: "nodes"
locked: false
pannable: false
position: {x: 237, y: 149}
removed: false
selectable: true
selected: false
}
When the nodes and edges are added to the graph, they are not rendered in the position in which they were when the graph was saved. I'm not sure what I'm doing wrong here. I've checked a couple of threads that mentioned using the 'preset' layout, but the way I'm implementing it doesn't seem to be working.
I've been trying a couple of rich text editors, and Quill seems to be the best tool to implement into my projects. I'm using Node/Express and MongoDB/Mongoose. In my 'newPost route', I have a form that just takes a title and the main content. Since I'm just testing it out, the title field is outside of the Quill editor. Here the error I'm getting:
This is after I hit "submit". The console shows not only the title but also the main content that has a code-block with syntax highlight which is exactly what I wanted. But it's not being added to the database.
There's also this message Use of Mutation Events is deprecated. Use MutationObserver instead., and it seems I'm required to change Quill's source code myself to fix this.
Getting the main content of the post on the console kind of gave me a feeling that I'm halfway of getting this to work.
Is there a not-so-hard way to get this to work? Thanks!!
js
var quill;
var metaData = [];
hljs.configure({ // optionally configure hljs
languages: ['javascript', 'ruby', 'python']
});
hljs.initHighlighting();

});
var form = document.querySelector('form');
form.onsubmit = function() {
// Populate hidden form on submit
var formContent = document.querySelector('input[name=content]');
formContent.value = JSON.stringify(quill.getContents());
console.log("Submitted", $(form).serialize(), $(form).serializeArray());
// No back end to actually submit to!

return false;
};
So I've created a combobox as such and when I attempt to insert using the addOption function it appears to work on some level. It shows a place in the combobox where it should be but it's a blank space. When I click on it, it shows undefined. Any idea what I'm doing wrong?
var infoCellList = [
{type: "settings", position: "label-left", labelWidth: 90, inputWidth: 130},
{type: "combo", name: "truckSelect", label: "Truck", value: ""}
];
var myFormInformation = vehicles_layout.cells('a').attachForm(infoCellList);
var truckSelectCombo = myFormInformation.getCombo("truckSelect");
truckSelectCombo.addOption("This is a test");
In the app I'm building, I have a data grid and some select boxes where the user can set filters and upon a selection it makes an AJAX call to get a new array of data from the server.
I have the grid initializing with default filters, but I can't figure out how to wipe the grid of all rows, and re-populate with a fresh array. I was trying dataView, but after reading some posts this seems to not be the answer. I find the official example-6 (ajax example) confusing.
I would like column sorting and column re-ordering to be retained when new data is loaded.
Here is the js I currently have which only initializes properly:
$(function(){
//update the grid when select values change
$('#qol_options :input').change(function(){
update_grid_data();
});
init_grid = function(){
// set grid options
var grid;
var columns = [
{id: "village", name: "Village", field: "village", sortable: true},
{id: "setting", name: "Setting", field: "setting", sortable: true},
{id: "hood", name: "N.hood", field: "hood", sortable: true},
{id: "timespan", name: "Time", field: "timespan", sortable: true},
{id: "count_0", name: "0", field: "count_0", sortable: true, width: 10},
{id: "count_1", name: "1", field: "count_1", sortable: true, width: 10},
{id: "count_2", name: "2", field: "count_2", sortable: true, width: 10},
{id: "count_3", name: "3", field: "count_3", sortable: true, width: 10},
{id: "count_4", name: "4", field: "count_4", sortable: true, width: 10},
{id: "count_6", name: "6", field: "count_6", sortable: true, width: 10},
{id: "count_7", name: "7", field: "count_7", sortable: true, width: 10},
{id: "count_8", name: "8", field: "count_8", sortable: true, width: 10},
{id: "count_total", name: "Total", field: "count_total", sortable: true},
{id: "pos_perc", name: "%", field: "pos_perc", sortable: true},
{id: "decile", name: "Decile", field: "decile", sortable: true},
];
var options = {
enableCellNavigation: true,
enableColumnReorder: true,
multiColumnSort: true
};
//get default grid data (all)
var grid_data = [{'village':0, 'setting':0, 'hood':0, 'timespan':0, 'count_0':0, 'count_1':0, 'count_2':0, 'count_3':0, 'count_4':0, 'count_6':0, 'count_7':0, 'count_8':0, 'count_total':0, 'pos_perc':0, 'decile':0}];
//create the grid instance
this_grid = new Slick.Grid("#data_table_container", grid_data, columns, options);
update_grid_data();
}
update_grid_data = function(){
var settingID = $('#settingID').val();
var villageID = $('#villageID').val();
var hoodID = $('#hoodID').val();
//init the grid
$.ajax({
type: "POST",
url: '<cfoutput>#APPLICATION.site_prefix#</cfoutput>/_global/ajax/ajax_handlers.cfm',
data: {'action': 'get_qol_report_data', 'villageID': villageID, 'settingID': settingID, 'hoodID': hoodID, 'itemID': 0, 'categoryID': 0},
dataType: 'json',
success: function(data) {
push_data_to_grid(data);
}
});
}
push_data_to_grid = function(data){
this_grid.setData(data);
this_grid.render();
}
//execute the grid init
init_grid();
});
I've faced the same problem. Please, try the below code.
function updateGridView(){
data_view.beginUpdate();
data_view.setItems(update_data);
data_view.endUpdate();
data_view.refresh();
grid.invalidate();
}
function grid_refresh(){
$.ajax("<cfoutput>#APPLICATION.site_prefix#</cfoutput>/_global/ajax/ajax_handlers.cfm",{
dataType : "json",
complete: function(xhr){
update_data = eval(xhr.responseText);
updateGridView();
}
})
}
Just call the grid_refresh() function.
I implemented something like this myself and here is how I have done it. I do use the dataview which will be wiped out every times and also the grid object which will be overwritten. I am not using your code, but instead I will show you the template which I use, I actually call the same function for loading & reloading but just make sure to empty() out the grid before you reload, see 1st line of code:
<div id="myGrid" style="width:100%;height:680px;"></div>
Then I made myself a button with an onclick event that looks something like this onclick=populateMyGrid() as a refresh button (it's actually a reload icon to make it nicer) and that event will call my function to reload the data through the $.getJSON() jQuery function, see the following code:
// Display some Market Indexes on a bar on top of the Grid
function populateMyGrid() {
// empty out the Grid before refreshing the data
$('#myGrid').empty();
// columns & options definition....
columns = [
{ id: "village", ............
];
options = {
enableCellNavigation: true,
editable: true,
............
};
ajaxURL = 'myPhpAjaxFileToPullData.php?action=getdata';
$.getJSON(ajaxURL, function (ServerResponse) {
dataView = new Slick.Data.DataView();
grid = new Slick.Grid('#myGrid', dataView, columns, options);
............
// initialize the model after all the events have been hooked up
dataView.beginUpdate();
dataView.setItems(ServerResponse.data);
dataView.endUpdate();
// Refresh the data render, if user only clicked on the refresh button instead of refreshing the whole page from browser
grid.updateRowCount();
grid.render();
}); // end of getJSON
} // end of populateMyGrid
From this code, the important part of it is to empty out the grid at first and then the last 2 rows of code for refreshing your grid with new data and make sure to re-render at last. That is the way I have it working, works like a charm...oh and I also display a text showing last refresh date+time, so it's more obvious to the user of how old the data is!
Even though it's not your code sample, you should get the idea...hope it helps :)
Also if you want to repopulate the grid with some kind of filtering you send the filtering via the ajaxURL of the $.getJSON or you could also replace it with a $.post and send it via the data property as your started, if you do it that way then move all your code into the success function (or a function call). Here is a possible solution for replacing the $.getJSON call... but please note that I did not try it but it should work:
//init the grid
$.ajax({
type: "POST",
url: '<cfoutput>#APPLICATION.site_prefix#</cfoutput>/_global/ajax/ajax_handlers.cfm',
data: {'action': 'get_qol_report_data', 'villageID': villageID, 'settingID': settingID, 'hoodID': hoodID, 'itemID': 0, 'categoryID': 0},
dataType: 'json',
success : getData
});
function getData() {
dataView = new Slick.Data.DataView();
grid = new Slick.Grid('#myGrid', dataView, columns, options);
............
// initialize the model after all the events have been hooked up
dataView.beginUpdate();
dataView.setItems(ServerResponse.data);
dataView.endUpdate();
// Refresh the data render, if user only clicked on the refresh button instead of refreshing the whole page from browser
grid.updateRowCount();
grid.render();
}
I'm looking for a best solution how to do this.
What I have:
// model
Ext.define("User", {
extend: "Ext.data.Model",
fields: [
{name: "id", type: "int"},
{name: "name"},
{name: "description", type: "string"}
]
});
// store with data
var oStore = new Ext.data.Store({
model: "User",
data: [
{id: 1, name: {name:"John"}, description: "Fapfapfap"},
{id: 2, name: {name:"Danny"}, description: "Boobooboo"},
{id: 3, name: {name: "Tom"}, description: "Tralala"},
{id: 4, name: {name:"Jane"}, description: "Ololo"},
]
});
// and finally I have a grid panel
Ext.create("Ext.grid.Panel", {
columns: [
{dataIndex: "id", header:"ID"},
{
dataIndex: "name",
header: "Name",
renderer: function(value){return value.name;},
editor: "textfield"},
{dataIndex: "description", header: "Description", flex: 1, editor: "htmleditor"}
],
plugins: [new Ext.grid.plugin.CellEditing({clicksToEdit: 2})],
store: store,
renderTo: document.body
});
When I doublecick on a cell I see [object] Object in editor's field, and when I enter valid value than I see empty cell in the grid.
So, the question is – how could I setup celleditor to get data not from record.name but from record.name.name?
You can override get and set methods on model, so the will support multi-level field names. Below is sample implementation.
Ext.define("User", {
extend: "Ext.data.Model",
fields: [
{name: "id", type: "int"},
{name: "name"},
{name: "description", type: "string"}
],
get: function(key) {
if (Ext.isString(key) && key.indexOf('.') !== -1) {
var parts = key.split('.');
var result = this.callParent([ parts[0] ]);
return result[parts[1]];
}
return this.callParent(arguments);
},
set: function(key, value) {
if (Ext.isString(key) && key.indexOf('.') !== -1) {
var parts = key.split('.');
var result = this.get(parts[0]);
result[parts[1]] = value;
this.callParent([ parts[0], result ]);
return;
}
this.callParent(arguments);
}
});
I am not sure if store detects change made to name.name field. If no, you should also probably mark record as dirty.
Working sample: http://jsfiddle.net/lolo/dHhbR/2/
The editor accepts whatever value is provided in the "dataIndex" field of the column. Since "name" is an object, that's what you're getting. After entering a name in the editor, value is equal to a string (not an object) and your renderer is trying to get the name property of the string.
The easiest way to fix this is to make the "name" field of your store a string instead of an object. However, I'm assuming there's a reason you want to do it this way.
The CellEditing plugin has three events it can listen for: beforeedit, edit, and validateedit. You can implement a beforeedit listener to get the "name" object from the column, then get the "name" property of that object and fill the editor with that value. Then on validateedit, get the value from the editor and set the "name" property of the "name" object in the record with that value.
For quick reference, here's the event definition: CellEditing events
An easier way is to modify your User Model object to map the "name" property differently:
{name: "name", mapping:'name.name'}
then everything else stays the same.
