I have dropdown, checkboxes and button submit. First, the user will choose at dropdown (position of work). Second, the user will select the checkbox and after that submit the data. Here, after refresh it should be appear back the previous selected dropdown and checkbox. But, I did not get it. Anyone here have more better solution?
JavaScript Dropdown
//dropdown position
$("#dropdown").kendoDropDownList({
optionLabel: "- Select Position -",
dataTextField: "functionName",
dataValueField: "hrsPositionID",
dataSource: {
transport:{
read: {
url: "../DesignationProgramTemplate/getData.php",
type: "POST",
data: function() {
return {
method: "getDropdown",
}
}
},
},
},
change: onChange
}).data('kendoDropDownList');
dropdownlist = $("#dropdown").data("kendoDropDownList");
Checkbox treeview (Kendo UI)
homogeneous = new kendo.data.HierarchicalDataSource({
transport: {
read: {
url: serviceRoot,
dataType: "json"
}
},
schema: {
model: {
id : "ehorsProgramID",
hasChildren: false,
children : "items"
}
},
filter: { field: "module", operator: "startswith", value: "Accounting" }
});
$("#AccountingTree").kendoTreeView({
check: onCheck,
checkboxes: { checkChildren: true } ,
// select: onSelect,
dataSource: homogeneous,
dataBound: function(){
this.expand('.k-item');
},
dataTextField: ["module","groupname","ehorsProgramName"]
});
AJAX for submit button
//AJAX call for button
$("#primaryTextButton").kendoButton();
var button = $("#primaryTextButton").data("kendoButton");
button.bind("click", function(e) {
var test = $("#dropdown").val()
$.ajax({
url: "../DesignationProgramTemplate/getTemplate.php",
type: "post",
data: {'id':test,'progid':array},
success: function () {
// you will get response from your php page (what you echo or print)
kendo.alert('Success'); // alert notification
//refresh
//location.reload("http://hq-global.winx.ehors.com:9280/ehors/HumanResource/EmployeeManagement/DesignationProgramTemplate/template.php");
},
});
});
JavaScript for check checkboxes
function checkedNodeIds(nodes, checkedNodes) {
for (var i = 0; i < nodes.length; i++) {
if (nodes[i].checked) {
checkedNodes.push(nodes[i].id);
}
if (nodes[i].hasChildren) {
checkedNodeIds(nodes[i].children.view(), checkedNodes);
}
}
}
var array = [];
function onCheck() {
var checkedNodes = [],treeView = $("#AccountingTree").data("kendoTreeView"),message;
var checkedNodes2 = [],treeView2 = $("#AdminSystemTree").data("kendoTreeView"),message;
var checkedNodes3 = [],treeView3 = $("#FnBTree").data("kendoTreeView"),message;
var checkedNodes4 = [],treeView4 = $("#HumanResourceTree").data("kendoTreeView"),message;
var checkedNodes5 = [],treeView5 = $("#InventoryManagementTree").data("kendoTreeView"),message;
var checkedNodes6 = [],treeView6 = $("#SalesMarketingTree").data("kendoTreeView"),message;
checkedNodeIds(treeView.dataSource.view(), checkedNodes);
checkedNodeIds(treeView2.dataSource.view(), checkedNodes);
checkedNodeIds(treeView3.dataSource.view(), checkedNodes);
checkedNodeIds(treeView4.dataSource.view(), checkedNodes);
checkedNodeIds(treeView5.dataSource.view(), checkedNodes);
checkedNodeIds(treeView6.dataSource.view(), checkedNodes);
if (checkedNodes.length > 0) {
message = checkedNodes.filter(x => !!x).join(",");
array = checkedNodes.filter(x => !!x);
} else {
message = "No nodes checked.";
}
}
Output
JavaScript for accessing the dataItem
// cookies
var values = ["LA1","LA6","LA12"]; //array nnti array ni la localstorage/cookies
var setTreeViewValues = function(values) {
var tv = $("#AccountingTree").data("kendoTreeView");
document.write(JSON.stringify(tv));
tv.forEach(function(dataItem) {
alert("test");
if (dataItem.hasChildren) {
var childItems = dataItem.children.data();
//document.write(JSON.stringify(childItems[0].items[0].programID));
}
// document.write(JSON.stringify(dataItem.items));
if (values.indexOf(childItems[0].items[0].programID) > -1) {
dataItem.set("checked", true);
}
});
};
setTreeViewValues(values);
console.log(datasource.data()[0].hasChildren);
// end cookies
So without knowing how you are binding the existing values to the page I am assuming you will be calling the page state somewhere within your Page loading.
So I have prepared a dojo that shows two different ways of setting the checked state of the items.
https://dojo.telerik.com/EhaMIDAt/8
1. Setting at the DataSource Level
So when setting up the datasource you can add an extra attribute to your collection called checked this will then set the checked value for the item or children items when loaded. using the example I have in the dojo:
{
id: 9,
text: "Reports",
expanded: true,
spriteCssClass: "folder",
items: [{
id: 10,
text: "February.pdf",
spriteCssClass: "pdf"
},
{
id: 11,
text: "March.pdf",
spriteCssClass: "pdf",
checked: true
},
{
id: 12,
text: "April.pdf",
spriteCssClass: "pdf"
}
]
}
this will set the checked state to true for you and show the checkbox as checked.
2. Manually Set the values after loading all the DataSources.
So I have done this on a button click but this could easily be done on a ready state or some other trigger if needed. Here the button when clicked will find the node in the tree with the text Research.pdf and either set it in a checked or unchecked state for you.
$('#checked').bind('click', () => {
var box = $("#treeview").data("kendoTreeView").findByText('Research.pdf').find('input[type="checkbox"]');
box.prop('checked', !box.is(':checked'));
});
Again the sample it taken from dojo link above. Hopefully this gives you a start on getting the values set according to your specific requirements.
I would probably have the value checked state set when you load the datasource for the treeview.
I want to chart created after an event like click a button, but chart does not created after clicking the button.
in sample there are 2 divs. container1 and container2,
container1 render partialView in razor and works fine and chart created, but container2 suppose to contains a chart after Change Data button clicked, it call an action via AJAX that renders same partialView as shown in container1 but does not work!
where I'm wrong?
action called and server responding and there is no error in console, this is after button click:
Index.cshtml(View)
<button id="changeDataButton">Change Data</button>
<div id="container1">
#{
Random random = new Random();
Html.RenderPartial("~/Views/Shared/chartPartialView.cshtml", new ChartModel()
{
CategoriesStackBar = new List<string>() { "A", "B", "C" },
Series = new List<Series>()
{
new ColumnSeries()
{
Name = "A",
Data = new List<ColumnSeriesData>()
{
new ColumnSeriesData()
{
Y = random.Next(100),
},
new ColumnSeriesData()
{
Y = random.Next(100),
},
new ColumnSeriesData()
{
Y = random.Next(100),
},
},
}
},
Id = "chart",
});
}
</div>
<div id="container2">
</div>
#section scripts{
<script src="~/Scripts/highcharts.js"></script>
<script>
$(document).ready(function () {
$('#changeDataButton').click(function (event) {
console.log('change data button clicked');
$.ajax({
async: false,
url: '/Home/UpdateChart',
success: function (partialView) {
console.log("success");
console.log(partialView);
$('#container2').innerHTML = (partialView);
}
})
})
});
</script>
}
(Controller)
public ActionResult UpdateChart()
{
Random random = new Random();
PartialViewResult partialViewResult = PartialView("~/Views/Shared/chartPartialView.cshtml", new ChartModel()
{

Series = new List<Series>()
{
new ColumnSeries()
{
Name = "A",
Data = new List<ColumnSeriesData>()
{
new ColumnSeriesData()
{
Y = random.Next(100),
},
new ColumnSeriesData()
{
Y = random.Next(100),
},
new ColumnSeriesData()
{
Y = random.Next(100),
},
},
Id = "dynamicChart",
}
}
});
return partialViewResult;
}
thanks in advance for your help
You can't use innerHTML directly on a jQuery object, you'll have to use .html() :
$('#container2').html(partialView);
I'm using web component and OpenAPI. and my web component works by valuable [options]'s data.
it's a pie chart and divided by DATA_VALUE's value and ITEM_NAME is label to show!
I extract data from OpenAPI and want to add to array of [data] in var options.
I need to use rows[1] to [11] but now I'm using only rows[1] and it work's well.
so now i'm trying to do for statement rows[1] to [11]!
I'm wondering how can i add rows[1] to [11]'s data to [data] in var options?
i tried like this but it occurs error. guess it isn't on right location or wrong .
options.data.push({DATA_VALUE: dataV, ITEM_NAME2: itemNm2});
this is entire code.
<body>
<div class='pie'></div>

}
}
};
$.ajax({

console.log(itemNm2);
console.log(dataV);

console.log(dataArray);
var jsonEncode = JSON.stringify(dataArray);
console.log(jsonEncode);*/
var options = {

options.data.push({DATA_VALUE: dataV, ITEM_NAME2: itemNm2});
pie = webponent.visual.pie.init($(".pie"), styles, options);
}
}
});
</script>
</body>
this is example value of OpenAPI

},
options.data.data.push({DTA_VAL: dataV, ITM_NM: itemNm2});
this works well!
I have tried to reload the data populated by an ajax call but I cant get it to work, it shows the old data even after using the reload method. The thing is that if I change some variables to populate a different data and try to call the following code without refreshing the page it does not reload the updated data =/ Here is my code:
function populateDataGrid() {
$.ajaxSetup({async: false});
var gridinfo="";
$.post("lib/function.php",{activity: activity, shift: shift, date: date},
function (output){
gridinfo = JSON.parse(output);
});
$.ajaxSetup({async: true});
// INITIALIZING THE DATAGRID
var dataSource = new StaticDataSource({
columns: [
{
property: 'id',
label: '#',
sortable: true
},
{
property: 'date',
label: 'date',
sortable: true
},
....
],
formatter: function (items) {
var c=1;
$.each(items, function (index, item) {
item.select = '<input type="button" id="select'+c+'" class="select btn" value="select" onclick="">';
c=c+1;
});
},
data: gridinfo,
delay:300
});
$('#grid').datagrid({
dataSource: dataSource
});
$('#grid').datagrid('reload');
$('#modal-fast-appointment-results').modal({show:true});
}
I found a solution... I had to create a new DataSource (lets call it "AjaxDataSource") and add the ajax request functionality within the data constructor:
(function (root, factory) {
if (typeof define === 'function' && define.amd) {
define(['underscore'], factory);
} else {
root.AjaxDataSource = factory();
}
}(this, function () {
var AjaxDataSource = function (options) {
this._formatter = options.formatter;
this._columns = options.columns;
this._delay = options.delay || 0;
this._data = options.data;
};
AjaxDataSource.prototype = {
columns: function () {
return this._columns;
},
data: function (options, callback) {
var self = this;
setTimeout(function () {
var data;
$.ajax({
url: 'getdata.php',
type: 'POST',
data: 'param1:param1,param2,param2,...,paramN:paramN', // this is optional in case you have to send some params to getdata.php
dataType: 'json',
async: false,
success: function(result) {
data = result;
},
error: function(data){
//in case we want to debug and catch any possible error
// console.log(data);
}
});
// SEARCHING
if (options.search) {
data = _.filter(data, function (item) {
var match = false;
_.each(item, function (prop) {
if (_.isString(prop) || _.isFinite(prop)) {
if (prop.toString().toLowerCase().indexOf(options.search.toLowerCase()) !== -1) match = true;
}
});
return match;
});
}
var count = data.length;
// SORTING
if (options.sortProperty) {
data = _.sortBy(data, options.sortProperty);
if (options.sortDirection === 'desc') data.reverse();
}
// PAGING
var startIndex = options.pageIndex * options.pageSize;
var endIndex = startIndex + options.pageSize;
var end = (endIndex > count) ? count : endIndex;
var pages = Math.ceil(count / options.pageSize);
var page = options.pageIndex + 1;
var start = startIndex + 1;
data = data.slice(startIndex, endIndex);
if (self._formatter) self._formatter(data);
callback({ data: data, start: start, end: end, count: count, pages: pages, page: page });
}, this._delay)
}
};
return AjaxDataSource;
}));
After defining the new DataSource, we just need to create it and call the datagrid as usual:
function populateDataGrid(){
// INITIALIZING THE DATAGRID
var dataSource = new AjaxDataSource({
columns: [
{
property: 'id',
label: '#',
sortable: true
},
{
property: 'date',
label: 'date',
sortable: true
},
....
],
formatter: function (items) { // in case we want to add customized items, for example a button
var c=1;
$.each(items, function (index, item) {
item.select = '<input type="button" id="select'+c+'" class="select btn" value="select" onclick="">';
c=c+1;
});
},
delay:300
});
$('#grid').datagrid({
dataSource: dataSource
});
$('#grid').datagrid('reload');
$('#modal-results').modal({show:true});
}
So now we have our datagrid with data populated via ajax request with the ability to reload the data without refreshing the page.
Hope it helps someone!
Currently I am doing this:
$(function () {
// Create the chart
$.getJSON('db_cpu.php', function(data) {
var chart = new Highcharts.StockChart({
chart: {
renderTo: 'container'
},
rangeSelector: {
enabled: false
},
title: {
text: 'Database utilization'
},
series: data
}, function (chart) {
normalState = new Object();
normalState.stroke_width = null;
normalState.stroke = null;
normalState.fill = null;
normalState.padding = null;
//normalState.r = null;
normalState.style = hash('text-decoration', 'underline');
hoverState = new Object();
hoverState = normalState;
pressedState = new Object();
pressedState = normalState;
//pressedState.style = hash('text-decoration', 'none');
chart_1DButton = chart.renderer.button('1D', 52, 10, function () {
$.getJSON('db_memory.php', function (data) {
console.log(data);
chart.series[0].setData(data);
chart.redraw();
});
unselectButtons();
chart_1DButton.setState(2);
}, normalState, hoverState, pressedState);
chart_1DButton.add();
});
function unselectButtons() {
chart_1DButton.setState(0);
}
});
});
when I clicked on the button, my chart does not diplay any data. dp_cpu.php and db_memory.php outputs json formated data that has name and data in it already. For exmaple dp_cpu.php outputs this data:
[{"name":"ServerA","data":[[1375142940000,1.85],[1375143540000,2.07],[1375144140000,1.96],[1375144740000,1.9],[1375145340000,2.06],[1375145940000,2.03],[1375146540000,1.69],[1375147140000,2.6],[1375147740000,2.1],[1375148340000,1.68],[1375148940000,2.03],[1375149540000,1.83],[1375150140000,1.84],[1375150740000,2.01],[1375151340000,1.88],[1375151940000,1.6],[1375152540000,2.02],[1375153140000,1.27],[1375153740000,1.47],[1375154340000,2],[1375154940000,1.97],[1375155540000,2.51],[1375156140000,3.59],[1375156740000,4.06],[1375157340000,4.13],[1375157940000,4.15],[1375158540000,4.19],[1375159140000,4.13],[1375159740000,4.44],[1375160340000,4.14],[1375160940000,4.15],[1375161540000,5.01],[1375162140000,4.13],[1375162740000,5],[1375163340000,4.97],[1375163940000,5.04],[1375164540000,5.09],[1375165140000,5.14],[1375165740000,4.93],[1375166340000,4.43],[1375166940000,5],[1375167540000,4.93],[1375168140000,5.1],[1375168740000,5.05],[1375169340000,5],[1375169940000,5.12],[1375170540000,4.14],[1375171140000,4.13],[1375171740000,4.85],[1375172340000,4.19],[1375172940000,4.13],[1375173540000,4.17],[1375174140000,2.02],[1375174740000,1.62],[1375175340000,1.77],[1375175940000,2.01],[1375176540000,1.86],[1375177140000,1.85],[1375177740000,2.1],[1375178340000,2.03],[1375178940000,1.79],[1375179540000,2.09],[1375180140000,1.95],[1375180740000,1.73],[1375181340000,2.12],[1375181940000,2.07],[1375182540000,1.65],[1375183140000,2.1],[1375183740000,2.03],[1375184340000,1.63],[1375184940000,2.13],[1375185540000,1.93],[1375186140000,1.65],[1375186740000,2.19],[1375187340000,1.98],[1375187940000,1.69],[1375188540000,2.13],[1375189140000,1.93],[1375189740000,1.72],[1375190340000,2.15],[1375190940000,2.07],[1375191540000,1.7],[1375192140000,2.15],[1375192740000,2.03],[1375193340000,1.73],[1375193940000,2.71],[1375194540000,1.96],[1375195140000,1.72],[1375195740000,2.15],[1375196340000,2.15],[1375196940000,1.85],[1375197540000,2.2],[1375198140000,1.93],[1375198740000,1.8],[1375199340000,2.19],[1375199940000,1.98],[1375200540000,1.85],[1375201140000,2.27]]}]
I have some more info. when I do another getJSON as below example, It looks like I need to reset each series. This is really not convenient. I need to be able to read and external file and just show whatever in that file as chart and redraw the chart. Any ideas?
$.getJSON('db_memory.php', function (data) {
console.log(data);
chart.series[0].setData([[1375142940000,100],[1375143540000,2.07],[1375144140000,1.96],[1375144740000,1.9],[1376408000000,90.06]]);
chart.series[1].setData([[1375142940000,10],[1375143540000,20.07],[1375144140000,40.96],[1375144740000,50.9],[1376408000000,50.06]]);
chart.series[2].setData([[1375142940000,10],[1375143540000,20.07],[1375144140000,40.96],[1375144740000,50.9],[1376408000000,20.06]]);
chart.series[3].setData([[1375142940000,10],[1375143540000,20.07],[1375144140000,40.96],[1375144740000,50.9],[1375145340000,10.06]]);
});
I have tried something like this and it is partially working with one problem. After clicking the button, I get the chart but my button disappears:

You can use addSeries() then you will not need to reset data, but in case when you use setData, redrawing is called, so redraw() can be skipped.
You only add your button when the chart is created.
The problem is that when you use the following code
, new Highcharts.StockChart..., the chart will load again, so it's will render without your button.
So, you have two options, add a callback that will add the button again, or use serie.setData to change it's data dinamically.
I'd go with the second option.
Other problem is that the response is an array, you have to access it the following way data[0]
Finally will have the following code:
chart_1DButton = chart.renderer.button('1D', 52, 10, function () {
$.getJSON('db_memory.php', function (data) {
// update data
// chart.series[0].setData( data[0].data );
// update series' options
chart.series[0].update(data[0]);
});
unselectButtons();
chart_1DButton.setState(2);
}, normalState, hoverState, pressedState);
after looking at different options, I realized that what I need to do maybe better implemented using html/css type buttons:

And using jquery click event I can load any kind of chart to the div:
$(document).ready(function(){
$("#prof_d").click(function(){
web_cpu();
});
});
