I am using jqGrid to display values on the client side. Initially the grid is empty and the user enters the data inline. According to the requirement, I need to submit the data once the user submits the form.
I intend to, just prior to submitting the form, format contents so that I can store the user entered details in the database. Is their any way I can get a grid data in the form of JSON?
Currently I am doing the same in the following way:
var ids = $(gridId).jqGrid('getDataIDs');
for ( var i =1; i <=ids.length; i++) {
var id = ids[i];
rowData = $("#"+grid).jqGrid('getRowData',id);
}
//add rowData to some global object and inturn to some hidden field and sending it the server.
Is there any other way to do the same?
I would recommend you to use
var gridData=$("#list").jqGrid('getGridParam','data');
to get full data from the grid. After you have all the data in one JavaScript object gridData you can modify it in the way which you need prior to submitting to the server.

How do I check if a particular field or column of a subgrid is business recommend or not? I want to do this using a web resource. Also due to some requirements, I will have to use the execution context of the form where the subgrid is present and not of the subgrid itself.
It is a little tricky because at the time that the form loads, the subgrid does not have data. So you have to use the Form's load event to attach a load event to the subgrid.
This is described in this MS Docs Page. You can do this like
function attachGridEvent(executionContext)
{
var formContext = executionContext.getFormContext();
var gridContext = formContext.getControl("gridCategories");
// We have the grid, now add a "load" event handler
gridContext.addOnLoad(MyGridLoadedEvent);
}
Now you've got a 'load' event for your grid so you can iterate through its rows and examine its data
I haven't been able to get this to work for subgrids that don't contain data
I get the first row in the sub grid. Once I have that we can loop through each of the row's attributes. Each attribute has the following methods:
getName Returns the logical name of the attribute of a selected grid
row.
getRequiredLevel Returns a string value indicating whether a
value for the attribute is required or recommended.
setRequiredLevel Sets whether data is required or recommended for the
attribute of a selected grid row before the record can be saved.
getValue Retrieves the data value for an attribute.
setValue Sets the
data value for an attribute.

I'm using some modern browser features (map, =>) but this code should work for you
function MyGridLoadedEvent(evt)
{
var gridContext = evt.getEventSource();
var rows = gridContext.getGrid().getRows();
if (rows.getLength() > 0)
{
let rowAttributes = rows.getByIndex(0).getAttribute();
let mappedResults = rowAttributes.map(x => x.getName() + " : " + x.getRequiredLevel());
alert(mappedResults);
}
}
I'm having trouble passing in the name of an element into a Dyanamics CRM web Resource javacript.
This code works:
function OnFormLoad()
{
var subGrid = window.parent.document.getElementById("Claims")
// do work
}
This code doesn't:
function OnFormLoad(GridName)
{
var subGrid = window.parent.document.getElementById(GridName)
// do work
}
How do I pass in the name of the element I want to work with?
Please refrain from using document.getElementById in Dynamics as it is not supported.
I believe you are trying to get GridContext and get Data from that Grid.
For Example on Account entity we have Contacts as Grid and then you wish to get data from that Grid.
I replicated the same on Account Entity (OnLoad) and get tried to get data from Contacts Grid.
When adding OnLoad event I have passed Grid name as Parameter as below.
I have added below onLoad Js on Account entity and was able to retrieve data from grid.
Note: I have added timeout because directly firing onload was not able to load complete page and then grid Name was not available.
function onLoad(executionContext,gridName){
setTimeout(function(){ getGridDatat(executionContext,gridName); }, 3000);
}
function getGridDatat(executionContext,gridName){
debugger
var formContext = executionContext.getFormContext();
var gridContext = formContext.getControl("Contacts"); // get the grid context
var myRows = gridContext.getGrid().getRows();
/*var myRow = myRows.get(arg);
var gridRowData = myRow.getData();*/
var firstRow =myRows.get(0).getData();
var firstRowAllAttributes = firstrow.entity.attributes.getAll()
var firstRowfirstAttributeValue = firstrow.entity.attributes.get(0).getValue()
}
If you want to perform some operation on change of data formGird then there is one more way to achieve this. Make your grid as Editable and then you can find Events for that gird as below and could perform your operations.
Purpose
I am trying to make a common answer database for a website form. The form is a description of computer hardware specifications, and I am trying to make it so that based on a model field, other fields are filled in automatically. The extension with have two buttons, "populate" which will based on the model field, check the database for a matching entry, and then populate data into the forms based on that. The second button being "save", which will take data in the fields and marry it to the model field and place it into the database.
Question
So, my main question is on interacting with the webpage itself, how do I grab data from the webpage, and then how do I make changes to fields?

You can do this with a Firefox Add-on SDK Page-mod, click here for the documentation
Here is an example for getting data:
Example Page-Mod
/lib/main.js:
var tag = "p";
var data = require("sdk/self").data;
var pageMod = require("sdk/page-mod");
pageMod.PageMod({
include: "*.mozilla.org",
contentScriptFile: data.url("element-getter.js"),
onAttach: function(worker) {
worker.port.emit("getElements", tag);
worker.port.on("gotElement", function(elementContent) {
console.log(elementContent);
});
}
});
/data/element-getter.js:
self.port.on("getElements", function(tag) {
var elements = document.getElementsByTagName(tag);
for (var i = 0; i < elements.length; i++) {
self.port.emit("gotElement", elements[i].innerHTML);
}
});
Is it possible to identify on a kendo UI grid which field was altered on a row edit?
Right now I am sending the entire row to the server that was changed. I would like to send
the request to the server to also include a variable holding the name
of the field that was edited.
Is something like that supported by kendo or
is there a work around for that?
This is not supported out of the box. However the grid API should allow this to be implemented. Check the edit and save events. In there you can listen to changes of the model instance which is currently being edit. Here is a quick example:
$("#grid").kendoGrid({
edit: function(e) {
e.model.unbind("change", model_change).bind("change", model_change);
}
});
function model_change(e) {
var model = this;
var field = e.field;
// store somewhere the field and model
}
I can see how to create a jqGrid link using:
colModel: [ {name:'myname',
formatter:'showlink',
formatoptions:{baseLinkUrl:'someurl.php', addParam: '&action=edit'}
This creates a request like /someurl.php?id=XX&action=edit and the display text will be the value of myname.
But in our case we don't need the myname text - our display text will be hard coded. We don't want to have to pass any additional data down in our JSON request - but it seems you need a JSON attribute for each column. How can we have a link without the add'l JSON column?
The formatter 'showlink' like all other formatter are used to format the data loaded in jqGrid from server or from the local data. So in case of your example you will not have 'myname' text (the column name) in the link but the cell value from the grid.
So if you want to use predefined formatter 'showlink' you have to fill the column data with the text which want to see in the link. You can do this either inside of your JSON data or filling/overwriting the text after the page are loaded for example inside of loadComplete event handle:
loadComplete: function() {
var grid = $("list");
var ids = grid.getDataIDs();
for (var i = 0, idCount = ids.length; i < idCount; i++) {
grid.setCell(id, 'myname', 'My text for link');
}
}
You can use also custom formatter and custom unformatter instead of 'showlink' predefined formatter. Then you can define the text of link like you want without filling any data in the grid.
