Get the JSON representation of a handsontable - handsontable

The following script can make a 3x2 editable table: JSBin:
<!DOCTYPE html>
<html>
<head>
<script src="https://docs.handsontable.com/pro/1.8.2/bower_components/handsontable-pro/dist/handsontable.full.min.js"></script>
<link type="text/css" rel="stylesheet" href="https://docs.handsontable.com/pro/1.8.2/bower_components/handsontable-pro/dist/handsontable.full.min.css">
</head>
<body>
<div id="example1" class="hot handsontable htRowHeaders htColumnHeaders"></div>
<br><br>
<div class="json-result">to print a JSON representation</div>
</body>
</html>
JavaScript:
document.addEventListener("DOMContentLoaded", function() {
function getData() {
return [
['A1', 'B1'],
['A2', 'B2'],
['A3', 'B3']];
}
var
example1 = document.getElementById('example1'),
settings1,
hot1;
settings1 = {
data: getData(),
rowHeaders: false,
colHeaders: false,
contextMenu: false
};
hot1 = new Handsontable(example1, settings1);
});
After manually changing some values in the table, I would like to return a JSON value that represents the value of the cells of the table, and print it at div json-result. Does anyone know what API I could use to do so?

Coincidentally, the function that you're looking for is called getData. You can use it on the Handsontable instance and you'll get an array of arrays, representing the current data that is in the table. From there on you can either reformat the json into whatever you like or simply JSON.strigify it. Here's a working example.

Kendo numberFormat change in culture

I want to format numeric column value as 55,25,236.30 in grid. I created a JS function and called from column template in grid. My JS function:
function NumberFormater(Price) {
kendo.culture("en-US");
kendo.cultures.current.numberFormat.groupSize = [3,2];
return kendo.toString(Price, "##,#.00");
}
but the value is showing like 5,525,236.30. According to this link the default value for groupSize is [3]. Is it not possible to set multiple values like [3,2] like numberformat in C#?
Make sure that the NumberFormater function receives a numeric argument. Below is a test page that works.
On a side note, I am not sure there is a need to set the culture and groupSize every time you execute the function.

kendo ui autocomplete - json file datasource - template - 404 Not Found error - /undefined URL

Below code has been thankfully provided by machun for toggling between RTL and LTR directions in Kendo UI widgets.
The code consists of:
HTML:
kendo autocomplete form plus a button to activate support for RTL and LTR language.
Script:
k-rtl class container
datasource (json file)
kendo autocomplete widget initializing + template to show image beside data and to open data links in the same tab
k-rtl class
The problem is that links don't open correctly. It shows a 404 Not Found error plus a /undefined at the end of the URL.

</script>
I advice to debug your function first then simply check the variable and make sure it contain the right thing. You overlooked a simple thing that your jquery dom selector isn't quite right resulting var href contain "undefined".
Change
var href = e.item.find("span").data("href");
To
var href = e.item.find("span[data-href]").attr("data-href");

jqGrid data load issue

I cannot get my data to show in jqgrid. I am using exactly the same code from this working example:
jqgrid won't load json data
My data is different, but not substantially so:
{"records":95,"page":1,"total":1,"rows":[{"Report":"f_cn_08","File":"F_CONTR.PBL"},{"Report":"f_cn_08","File":"F_CONTR.PBL"},{"Report":"f_cn_08","File":"F_CONTR.PBL"},{"Report":"f_cn_08","File":"F_CONTR.PBL"},{"Report":"f_cn_08","File":"F_CONTR.PBL"},{"Report":"f_cn_08","File":"F_CONTR.PBL"},{"Report":"f_cn_08","File":"F_CONTR.PBL"},{"Report":"f_cn_08","File":"F_CONTR.PBL"},{"Report":"f_cn_08","File":"F_CONTR.PBL"},{"Report":"f_cn_08","File":"F_CONTR.PBL"}]}
I hate to re-open the same issue, but this is very frustrating to me.

I am tempted to fork the jqgrid source and add some console.log messages to it! Because failing mysteriously with no message is a great barrier to adoption.
The JSON data which you use has another format as in the referenced question, so jqGrid is, of cause, not able to read your data. jsonReader option describes the format of input data for jqGrig. If rows array contains object with named properties one should use jsonReader: {repeatitems: false}. In the case the colModel parameter should have columns with name: "Report" and name: "File".
The next problem of your JSON data - it has no id information for items of the rows. In the case jqGrid will use integer values 1, 2, 3... as rowids. Such automatical generation of ids will work good only for one grid per page. The second grid will have id duplicates. So it's recommended to include additional property id in every item of the array rows of the JSON input.

Kendo UI: Can't add a node to treeview when using custom schema

I have a kendo tree initialized with the following datasource:
var dataSource = new kendo.data.HierarchicalDataSource({
transport: {
read: {
url: '/Quota/Home/GetTemplateHierarchy',
dataType: 'json',
data: { hierarchyID: hierarchyID, quotaSetID: quotaSetID, batchSize: 10 }
}
},
schema: {
model: {
id: 'id',
hasChildren: 'hasChildren',
children: 'items',
fields: {
text: 'text'
}
}
}
});
Does anyone know how to add and create a new node for this datasource? I've tried the generic treeview.append({ text: "Boo"}) but it doesn't do anything. I've successfully removed nodes, but can't seem to add any. The documentation is not clear as to how to add anything when using custom schemas.
Not sure what do you want to be the text of the node that you want to display. So I will guess that you want to display the only element in the schema nodelevel
The data in that case should be: { nodelevel : 99 }
Following a complete example where I have an initial node and then I append sub-nodes to the selected node.

Here I create a tree with a content loaded from JSON (it should be replaced by your ajaxAntiForgery). There is one node in the tree that has an icon (k-i-pencil). Then I call a function addLoadMore that intercepts clicks on the node with k-i-pencil and add new content to this node -using insertBefore for inserting the new content before the content with k-i-pencil and then removes the old node).
I think that this example is pretty similar to what you are doing with your button.
So, take a look into loadMore function to see how I detect the node corresponding to where I clicked (I extract the uid and the find the node with this uid by using tree.findByUid).
Finally I remove the original node (invoking tree.remove) and set again the interceptor for the new nodes with k-i-pencil.
Hopefully this is pretty close to what you have.
The treeview.append should work and append new node to the root level if you do not specify a note to append it to.
You could also use the dataSource.insert({text:"foo"}) or dataSource.add.

Jqgrid ColumnChooser column order change is not working

I am new to jQuery & jgrid. I am trying to use columnchooser to both to let user remove columns and change column order. Removing and adding columns are working fine. But changing the column order is not working. Below is what I have in the code.

// Modified to work with jquery.ui.1.8
if ($.Widget === undefined)
$.widget.prototype.destroy.apply(this, arguments);
else {
$.Widget.prototype.destroy.apply(this, arguments);
return this;
}}
And I am using the columnchooser as below.
jq("#grid").jqGrid('navButtonAdd','#pager',
{ caption: "Columns",
title: "Reorder Columns",
onClickButton : function (perm){
jq("#grid").jqGrid('columnChooser');
}
});
Below is what I have tried so far.
When I add {"msel_opts": $.ui.multiselect.defaults} as an option, I am getting ui undefined JS error.
When I tried to include grid.jqueryui.js, got object or method not supported.
I am stuck # this. Would somebody help please?
It is difficult to find the error in your code, because you posted only one code fragment. Probably you try to add the button in the navigator toolbar with respect of 'navButtonAdd' before you created the navigator toolbar with respect of 'navGrid'.
In any way one small working example here could help you to find your error.
For others who are in the same requirement, you may consider my columnchooser implementation.
My Dialog Form Declaration. (Dialog box which will be shown when columnchooser button is clicked.
All required fields will not be allowed to remove.
Creating the ColumnChooser Button for my Grid.
jq("#grid").jqGrid('navButtonAdd','#pager',{
caption: "Columns",
title: "Customize Columns",
onClickButton : function (){
/*jq("#grid").jqGrid('columnChooser',{
height:columnChooserHt
});*/
createDialogDiv();
jq( "#dialog-form" ).dialog('open');
}
});
Adding Save(OK) and Cancel Buttons to my Div.
jq(function(){
jq( "#dialog-form" ).dialog({
autoOpen: false,
height: 300,
width: 350,
modal: true,
buttons: {
"OK": function() {
changeColView();
jq( "#dialog-form" ).dialog('close');
},
Cancel: function() {
jq( "#dialog-form" ).dialog('close');
}
},
close: function() {
}
});
});
Function which inserts the column names with the select boxes which needed to be displayed on the ColumnChooser Dialog Box.
function createDialogDiv(){
var colModelDiv = jq("#grid").jqGrid('getGridParam','colModel');
var colNamesDiv = jq("#grid").jqGrid('getGridParam','colNames');
//alert(JSON.stringify(colModelDiv));
//alert(JSON.stringify(colNameDiv));
var container = document.getElementById('dialog-form');
//alert(colNamesDiv.length);
var chckBox="";
for(i=0;i<colNamesDiv.length;i++){
if(colModelDiv[i].hidden && colModelDiv[i].hidden == true ){
chckBox+="<input type='checkbox' id='"+colNamesDiv[i]+"' name='"+colNamesDiv[i]+"' value='"+colModelDiv[i].name+"'>"+colNamesDiv[i]+"</input><br/>";
}else{
if(colModelDiv[i].editrules && colModelDiv[i].editrules.required){
chckBox+="<input type='checkbox' id='"+colNamesDiv[i]+"' name='"+colNamesDiv[i]+"' value='"+colModelDiv[i].name+"' disabled>"+colNamesDiv[i]+"</input><br/>";
}
else
chckBox+="<input type='checkbox' id='"+colNamesDiv[i]+"' name='"+colNamesDiv[i]+"' value='"+colModelDiv[i].name+"' checked>"+colNamesDiv[i]+"</input><br/>";
}
}
container.innerHTML=chckBox;
}
Finally the actual method which changes the Columns chosen from Columnchooser.
function changeColView(){
var colModelDiv = jq("#grid").jqGrid('getGridParam','colModel');
var colNamesDiv = jq("#grid").jqGrid('getGridParam','colNames');
for(i=0;i<colNamesDiv.length;i++){
var chckBox=document.getElementById(colNamesDiv[i]);
if(chckBox && chckBox.value && (!(chckBox.checked || chckBox.disabled))){
jq("#grid").jqGrid('hideCol',chckBox.value);
}
if(chckBox && chckBox.checked){
jq("#grid").jqGrid('showCol',chckBox.value);
}
}
jq("#grid").trigger('reloadGrid');
}
Plz let me know your thoughts on this one.
