I am starting to use the jQuery plug in jqGrid for rendering nice tables, I want to make just one column editable.
I manage to render a table where a textbox come up when i click on my editable column, nevertheless I don't manage to catch when a cell has been edited (after enter has been pressed) . When I read doc, I suppose I have to use aftersavefunc but I don't know where and how it has to be used.
Could you help me please?
Bellow my exemple I would like to complete.
var mydata = [{
name: "Toronto",
country: "Canada",
continent: "North America"
}, {
name: "New York City",
country: "USA",
continent: "North America"
}, {
name: "Silicon Valley",
country: "USA",
continent: "North America"
}, {
name: "Paris",
country: "France",
continent: "Europe"
}]
function edit(id) {
var table = jQuery(this);
table.jqGrid('editRow', id,
{
keys: true,
});
}
$("#grid").jqGrid({
data: mydata,
datatype: "local",
colNames: ["Name", "Country", "Continent"],
colModel: [{
name: 'name',
index: 'name'
}, {
name: 'country',
index: 'country',
editable: true,
}, {
name: 'continent',
index: 'continent'
}],
onSelectRow: edit
});

<table id="grid"></table>
You can specify aftersavefunc for example together with other options of editRow:
table.jqGrid('editRow', id, {
keys: true,
url: "myServerUrl", // it's optional
aftersavefunc: function (rowid) { // can add jqXHR, sentData, options
alert(rowid + " is saved");
}
});
The next problem: I would strictly recommend you to add id property in the input data used for filling the grid. The id property will be saved as the value of id attribute of every row (<tr>) element, used in callbacks and will be send to the server on editing. I'd recommend you to remove all index properties from jqGrid too and add the option autoencode: true to jqGrid. If you use old 4.6 version then you should add gridview: true option to improve the performance of the grid and to add height: "auto" option too.
The next problem: it's recommended to save/discard previously edited row inside of onSelectRow. You need call saveRow or restoreRow. You current code can produces many simultaneously edited rows. The user can forget to press Enter and thought that the rows are already modified. I'd recommend you to add at least navigator bar with edit/save/cancel buttons by inlineNav additionally to your current code. It helps some users to save the rows.
One more remark. jqGrid 4.6 is already old. There are currently two main forks of jqGrid: free jqGrid in the current version 4.13.0 and commercial version Guriddo jqGrid JS. Both versions contains many new features, but there will be more and more different. I develop free jqGrid after the post about renaming jqGrid to Guriddo jqGrid JS and changing the license agreement. I provided free jqGrid under the same licenses (MIT and GPLv2) like old versions of jqGrid (4.6 for example). You can use it from CDNs too (see the wiki article). jqGrid 4.6 is dead. No bug fix or new feature will be developed. You wrote that you are starting to use jqGrid. In the case it's especially bad to use some old version.

We are using Tabulator (4.8.3) and have a SELECT based header filter on one column. It all works great except we are trying to add some formatting to some of the select options. They display in the select dropdown with the formatting as expected. However once a selection is made, the selected text displays with the raw html (not formatted).
A JS fiddle here shows what we mean. Make a selection and see the formatting displayed in the selection text (e.g. the bold tags and non-breaking spaces).
We looked for a headerFilterFormatter or something along those lines in Tabulator but could not find anything. We also saw this post:
How do I create a multi-select header filter in tabulator?, but it seems like overkill to write all this just to sanitize option texts display.
We don't care id the selected text is formatted or not, we just don't want the html displaying in the value. We could possibly sanitize it externally every time a selection is made, but that does not seem like a great idea because it will tightly couple everything.
Does anyone know if there is a quick, easy way to address this in Tabulator?
var table = new Tabulator("#table", {
layout: "fitDataFill",
columns: [{
title: "ID",
field: "id"
},
{
title: "Topic",
field: "topic",
width: 120,
headerFilterPlaceholder: "-- Select --",
headerFilter:"select",
headerFilterParams: {values: paramLookup}
},
],
});
var tableData = [{
id: 1001,
topic: "1.0",
},
{
id: 1002,
topic: "1.1",
},
{
id: 1003,
topic: "2.0",
},
{
id: 1004,
topic: "3.0",
},
];
function paramLookup(cell){
return {
"1.0":"<b>1.0</b>",
"1.1":" 1.1",
"2.0":"<b>2.0</b>",
"3.0":"<b>3.0</b>",
};
}
table.setData(tableData);
The problem you are facing is you are trying to style the labels for the select list values in the values array. The select editor uses an input element to show the selected value, therefor when you are selecting a value it is showing the label as text.
The correct approach is to include the actual value in the label and then use the listItemFormatter to format the list as wanted, that way you store a plain text value against the label and display it as html:
{
title: "Topic",
field: "topic",
width: 120,
headerFilterPlaceholder: "-- Select --",
headerFilter:"select",
headerFilterParams: {
values: [1.0, 1.1, 1.2],
listItemFormatter:function(value, title){
return "<b>" + title + "</b>";
},
}
},
I have some rows I hide like that:
$("#"+rowid).hide();
My problem is that when the user clicks to sort a colmun, the hidden rows reappeared. There is a way to avoid this?
EDIT
I will try to explain a little bit more what I did with code example.
I start to create my grid with this params (and without datas).
var params = {
datatype: "local",
data: [],
caption: "Grid",
colNames:[ "Column A", "Column B" ],
colModel:[
{ name:"colA", key: true },
{ name:"colB" }
]
};
For some reasons, I reload next the grid with datas, like this:
$("#myGrid").jqGrid("clearGridData")
.jqGrid("setGridParam", { data: myDatas })
.trigger("reloadGrid");
And I have checkboxes with listeners, like this one:
$("#checkbox1").on("change", onCheckbox1Changed);
function onCheckbox1Changed() {
var rowid = ...;
var datas = $("#myGrid").jqGrid("getRowData");
for(var key in datas) {
if(datas[keys].colB === "" && $("#checkbox1").val() === true) {
$("#"+rowid).show();
} else if(datas[keys].colB === "" && $("#checkbox1").val() === false) {
$("#"+rowid).hide();
}
}
}
This code works like I want. Rows are hidden/shown depending on checkboxes. The problem is when I clik on a column to sort it, the hidden columns reappeared.
EDIT 2
I could force the grid to hide the rows after a sort. But I didn't find where I can find an event like "afterSort". There is "onSortCol" but it is called before the sort.
A solution will be to force that using "loadComplete". Like this:
var params = {
// ...
loadComplete: onLoadComplete
}
function onLoadComplete() {
onCheckbox1Changed();
}
I tried it and it works. But I am not very "fan" with this solution.
I find hiding some rows after displaying the page of data not the best choice. The main disadvantage is the number of rows which will be displayed. You can safe use $("#"+rowid).hide(); method inside of loadComplete only if you need to display one page of the data. Even in the case one can see some incorrect information. For example, one can use viewrecords: true option, which place the text like "View 1 - 10 of 12" on right part of the pager.
I personally would recommend you to filter the data. You need to add search: true option to the grid and specify postData.filters, which excludes some rows from displaying:
search: true,
postData: {
filters: {
groupOp: "AND",
rules: [
{ field: "colA", op: "ne", data: "rowid1" },
{ field: "colA", op: "ne", data: "rowid2" }
]
}
}
If you would upgrade from old jqGrid 4.6 to the current version (4.13.6) of free jqGrid, then you can use "ni" (NOT IN) operation:
search: true,
postData: {
filters: {
groupOp: "AND",
rules: [
{ op: "ni", field: "id", data: "rowid1,rowid2" }
]
}
}
In both cases jqGrid will first filter the local data based on the filter rules and then it will display the current page of data. As the result you will have the perfect results.
Sorting of such grid will not not change the filter.
Don't hide columns after the creation of the table, hide them directly when you create the grid using the option hidden, like this:
colNames: ['Id', ...],
colModel: [
{ key: true, hidden: true, name: 'Id', index: 'Id' },
....
]
If you want to hide columns on particular events after the creation of the grid, look at this article.
Hope it was you were looking for.
I have a JQuery grid which is being populated on a button click based on certain drop-down selections.
The grid is loaded with data on the first button click. But on subsequent clicks the grid doesn't reload based on the changed drop-down selections.
The grid data loaded on the first button click persists until and unless i reload the page.
I have gone through some solutions online,such as
using $("#tblJQGrid").trigger("reloadGrid");for subsequent clicks except for the first click
cache:false property.
But none of them worked.
Here is my jqgrid code for reference
function BindGridData()
{
$("#tblJQGrid").jqGrid(
{url: "#Url.Action("GetGeographyBreakUpData", "GeoMap")"+ "?Parameters=" + Params + "",
datatype: "json",
//data: { "Parameters": Params },
async: false,
mtype: 'GET',
cache: false,
colNames: ['Id','GeoGraphy', 'Completed', 'InProgress'],
colModel: [
{ name: 'Id', index: 'Id', width: 20, stype: 'text',hidden:true },
{ name: 'Geography', index: 'Geography', width: 150 },
{ name: 'Completed', index: 'Completed', width: 150 },
{ name: 'InProgress', index: 'InProgress', width: 150 },
],
pager:'#pager',
jsonReader: {cell:""},
rowNum: 10,
sortorder: "desc",
sortname: 'Id',
viewrecords: true,
caption: "Survey Status:Summary",
scrollOffset: 0});
}
And here is how i am initialising the button click event
$(document).ready(function () {
var firstClick=true;
$("#btnSubmit").click(function(){
btnSubmitClick();
debugger
if(!firstClick)
{
$("#tblJQGrid").trigger("reloadGrid");
}
firstClick=false;
BindGridData();
});
});
Can someone tell me what i am doing wrong?
It seems that there are typical misunderstanding what the code $("#tblJQGrid").jqGrid({...}); do. It's create the grid. It means that in converts the empty table <table id="btnSubmit"></table> in relatively complex structure of divs and tables. See here. After understanding of that it should be clear that the second calling of BindGridData has no sence, becsue table#btnSubmit is not more empty. jqGrid tests it and just do nothing. Thus your current code just trigger reloadGrid with the old URL (see Params).
To fix the problem you have two main options:
usage url: "#Url.Action("GetGeographyBreakUpData", "GeoMap")" and postData with properties defined as functions (see the old answer)
recreate the grid on click instead of triggering reloadGrid. You can call GridUnload method (see the old answer) before call of BindGridData.
I need to show an array of objects in the table like representation. Table has columns with the properties, and when clicked on the column it should show more data inside the table. It should be sortable.
Is there a JS library that could do this, so I dont have to write this from scratch?
Please see the attached image with the JSON object.
When the user clicks on Ana, additional row is inserted.
I created the demo https://jsfiddle.net/OlegKi/kc2537ty/1/ which demonstrates the usage of free jqGrid with subgrids. It displays the results like
after the user clicks on the "+" icon in the second line.
The corresponding code you can find below
var mydata = [
{ id: 10, name: "John", lname: "Smith", age: 31, loc: { location: "North America", city: "Seattle", country: "US" } },
{ id: 20, name: "Ana", lname: "Maria", age: 43, loc: { location: "Europe", city: "London", country: "UK" } }
];
$("#grid").jqGrid({
data: mydata,
colModel: [
{ name: "name", label: "Name" },
{ name: "lname", label: "Last name" },
{ name: "age", label: "Age", template: "integer", align: "center" }
],
cmTemplate: { align: "center", width: 150 },
sortname: "age",
iconSet: "fontAwesome",
subGrid: true,
subGridRowExpanded: function (subgridDivId, rowid) {
var $subgrid = $("<table id='" + subgridDivId + "_t'></table>"),
subgridData = [$(this).jqGrid("getLocalRow", rowid).loc];
$("#" + subgridDivId).append($subgrid);
$subgrid.jqGrid({
idPrefix: rowid + "_",
data: subgridData,
colModel: [
{ name: "location", label: "Localtion" },
{ name: "city", label: "City" },
{ name: "country", label: "Country" }
],
cmTemplate: { align: "center" },
iconSet: "fontAwesome",
autowidth: true
});
}
});
Small comments to the code. Free jqGrid saves all properties of input data in data parameter. I added id property to every item of input data. It's not mandatory, but it could be helpful if you would add more functionality to the grid. See the introduction for more details.
The columns are sortable based on the type of the data specified by sorttype property of colModel. To simplify usage some standard types of data free jqGrid provides some standard templates which are shortcurts for some set of settings. I used template: "integer" in the demo, but you could replace it to sorttype: "integer" if only sorting by integer functionality is important.
If the user click on "+" icon to expand the subgrid then jqGrid inserts new row and creates the div for the data part of the subgrid. You can replace subGridRowExpanded from above example to the following
subGridRowExpanded: function (subgridDivId) {
$("#" + subgridDivId).html("<em>simple subgrid data</em>");
}
to understand what I mean. The unique id of the div will be the first parameter of the callback. One can create any common HTML content in the subgrid. Thus one can create empty <table>, append it to the subgrid div and
then convert the table to the subgrid.
To access to the item of data, which corresponds to the expanding row one can use $(this).jqGrid("getLocalRow", rowid). The return data is the item of original data. It has loc property which we need. To be able to use the data as input for jqGrid we create array with the element. I's mostly all, what one have to know to understand how the above code works.
You can add call of .jqGrid("filterToolbar") to be able to filter the data or to add pager: true (or toppager: true, or both) to have the pager and to use rowNum: 5 to specify the number of rows in the page. In the way you can load relatively large set of data in the grid and the user can use local paging, sorting and filtering. See the demo which shows the performance of loading, sorting and filtering of the local grid with 4000 rows and another one with 40000 rows. All works pretty quickly if one uses local paging and not displays all the data at once.
I use datatables.net for all my "more complex than lists"-tables. I It's a very well kept library with loads of features and great flexibility.
In the "con" column I would say that it's so complex that it probably has quite a steep learning curve. Although the documentation is great so there is always hope for most problems.
I have a complex JSON response that is iterated over using ng-repeat. Only a relatively small subset of the attributes within the result set are displayed on the screen, so filtering of the results should be restricted to values the user can actually see, otherwise the filtering behavior would be confusing to the end-user.
Since one of the attributes I wish to filter on is a deeply nested array, a custom filter was needed since the built-in AngularJS filterFilter does not iterate over the array elements to the best of my knowledge.
I was able to get this working some time back in AngularJS v1.2.28, but unfortunately it appears to break during a migration to v1.4.3. I have not spent time to isolate where in the release cadence this functionality broke however.
I have not found any helpful information in the migration guides that would indicate what has changed. All I know is that the actual/expected parameters to the filter receive different values in the latest major version of AngularJS, which leads to the failure.
ng-repeat filter expression:
<li ng-repeat="user in users | list_filter:{establishment: {id: filterText, names: [{name: filterText}], locations: [{streetAddress1: filterText, streetAddress2: filterText, city: filterText, stateProvince: filterText, postalCode: filterText}]}}">
Example data structure of a single element:
data = [{
id: 234567,
name: 'John Doe',
establishment: {
id: 067915959,
locations: [{
id: '134B030365F5204EE05400212856E994',
type: 'postal',
streetAddress1: 'P O BOX 900',
city: 'Grover',
stateProvince: 'CA',
postalCode: '902340900',
isoCountryCode: 'US',
region: 'MONROE'
}, {
id: '999B030365F4204EE05400212856E991',
type: 'postal',
streetAddress1: '2590 Atlantic Ave',
city: 'Fredricks',
stateProvince: 'VA',
postalCode: '45487',
isoCountryCode: 'US',
region: 'MONROE'
}],
names: [{
name: 'Grover Central School Dst',
type: 'PRIMARY'
}, {
name: 'Grover Central School Dst',
type: 'MARKETING'
}, {

}
}];

Edit:
The issue appears to be directly related to the changes introduced in v1.3.6.
It appears the issue is related to the fact that an implicit AND condition is now being applied but was previously an implicit OR, which is what is desired in my case. You can import the old version as a separate filter, if the old behavior is desired.
