How to get the name/id of the sort column and the sort-order of the column in slickgrid? I'm able to set the sort column using grid.setSortColumn("column"), and would like to get the sort column and it's sort order.
grid.getSortColumns()
will give you array of objects like this :
[Object { columnId= "ProjectProgram", sortAsc=false}]
You can access it in the callback function to onSort:
var grid = new Slick.Grid("#sf_grid", dataView, columns, options);
grid.onSort.subscribe(function(e, args) {
var sortdir = args.sortAsc ? 1 : -1; //get the sort order
var sortcol = args.sortCol.field; //get the sort column
});

I am trying to merge storefront filtering and sorting in my custom theme collections page in Shopify.
Both things work, but the 'sort_by' parameters are overwriting the filtering ones when these are multiple.
i.e of how the URL should look once filtering with two parameters (sizes XXS and XL) and sorting by ascending price:
../collections/new-arrivals?filter.v.option.size=XXS&filter.v.option.size=XL&sort_by=price-ascending
But this is what happens when sorting:
../collections/new-arrivals?filter.v.option.size=XXS&sort_by=price-ascending
Second filtering parameter gets overwritten by the sorting one.
Pasting below my code for the JS piece that triggers the sorting behaviour.
// sortby
$(function() {
Shopify.queryParams = {};
if(location.search.length) {
for(var aKeyValue, i = 0, aCouples = location.search.substr(1).split('&'); i < aCouples.length; i++) {
aKeyValue = aCouples[i].split('=');
if (aKeyValue.length > 1) {
Shopify.queryParams[decodeURIComponent(aKeyValue[0])] = decodeURIComponent(aKeyValue[1]);
}
}
}
document.querySelector('.sort-by').addEventListener('change', function(e) {
var value = e.currentTarget.value;
Shopify.queryParams.sort_by = value;
location.search = new URLSearchParams(Shopify.queryParams).toString();
});
})
Has someone ever tried to achieve something like this?
I would appreciate any help.
Thanks in advance,
I have a datatable and the 5th column of this table contains several labels. I also have a separate labels list with checkboxes, where user can select multiple labels and filter the table. I found the following way to filter the table:
table.column(5).search('value1|value2', true, false).draw();
This returns all the rows, that contain value1 OR value2, but I need to return the rows that contain both, value1 AND value2, but I could not find anything about this. I tried something like this as an experiment, but it did not work:
table.column(5).search('value1&value2', true, false).draw();
How do I search the datatable with an AND condition?
As andrewJames suggested in the comment, I used the Datatables search plug-in and created a custom filter function:
$('.labels-filter-button').unbind().click(function(){
$.fn.dataTable.ext.search.push(function (settings, data, dataIndex) {
let selectedLabels = $('#labelsFilterSelector').val();
let content = data[5];
let rowIncludes = true;
for (var i = 0; i < selectedLabels.length; i++) {
if (content.indexOf(selectedLabels[i]) == -1){
rowIncludes = false;
}
}
return rowIncludes;
});
table.draw();
$.fn.dataTable.ext.search.pop();
});
Works like a charm on any number of inputs.
In Parse, let's say I have 1000 rows of Bar. Say I want to find the rows at specific 'positions' based on when the row was created.
What I've tried:
var _ = require('lodash');
var indexes = [1,2,3];
var query = new Parse.Query('Bar');
query.addAscending('createdAt'); // oldest first for predictable ordering
var promises = indexes.map((i) => {
var q = _.clone(query);
q.skip(i);
return q.first();
});
Parse.Promise.when(promises)
.done((results) => {
console.log(results); // returns ONE row only.
});
I was expecting an array of results, of all the first() promises' results. Alas, I cannot understand why Parse.Promise.when only returns one result.
I have setup drag and drop headings to group by the relevant column from jQgrid Grouping Drag and Drop
It works great however I am trying to display the column name before the value i.e.
Client : Test data data
Client : Test2 data data
I've been going around in circles if any one could help.
if i take the same code used for the dynamic group by which should be the (column Name)
I end up with The Column data not the column name.
$('#' + gridId).jqGrid('groupingGroupBy', getheader());
function getheader() {
var header = $('#groups ol li:not(.placeholder)').map(function () {
return $(this).attr('data-column');
}).get();
return header;
}
if i use the same function in group text I get data not the column name.
I've come from C# and I am very new to jQuery.
If any one could help it would be greatly appreciated.
Kind Regards,
Ryan
First of all the updated demo provides the solution of your problem:
Another demo contains simplified demo which demonstrates just how one could display the grouping header in the form Column Header: Column data in the grouping header instead of Column data used as default.
The main idea of the solution is the usage of formatDisplayField property of groupingView which I suggested originally in the answer. The current version of jqGrid support the option. If one would use for example the options
grouping: true,
groupingView: {
groupField: ["name", "invdate"],
groupColumnShow: [false, false],
formatDisplayField: [
customFormatDisplayField,
customFormatDisplayField
]
}
where customFormatDisplayField callback function are defined as
var customFormatDisplayField = function (displayValue, value, colModel) {
return colModel.name + ": " + displayValue;
}
will display almost the results which you need, but it will uses name property of colModel instead of the corresponding name from colNames. To makes the final solution one use another implementation of customFormatDisplayField:
var getColumnHeaderByName = function (colName) {
var $self = $(this),
colNames = $self.jqGrid("getGridParam", "colNames"),
colModel = $self.jqGrid("getGridParam", "colModel"),
cColumns = colModel.length,
iCol;
for (iCol = 0; iCol < cColumns; iCol++) {
if (colModel[iCol].name === colName) {
return colNames[iCol];
}
}
},
customFormatDisplayField = function (displayValue, value, colModel, index, grp) {
return getColumnHeaderByName.call(this, colModel.name) + ": " + displayValue;
};
I'm displaying a table with multiple rows and columns. I'm using a JQUERY plugin called uiTableFilter which uses a text field input and filters (shows/hides) the table rows based on the input you provide. All you do is specify a column you want to filter on, and it will display only rows that have the text field input in that column. Simple and works fine.
I want to add a SECOND text input field that will help me narrow the results down even further. So, for instance if I had a PETS table and one column was petType and one was petColor -- I could type in CAT into the first text field, to show ALL cats, and then in the 2nd text field, I could type black, and the resulting table would display only rows where BLACK CATS were found. Basically, a subset.
Here is the JQUERY I'm using:
$("#typeFilter").live('keyup', function() {
if ($(this).val().length > 2 || $(this).val().length == 0)
{
var newTable = $('#pets');
$.uiTableFilter( theTable, this.value, "petType" );
}
}) // end typefilter
$("#colorFilter").live('keyup', function() {
if ($(this).val().length > 2 || $(this).val().length == 0)
{
var newTable = $('#pets');
$.uiTableFilter( newTable, this.value, "petColor" );
}
}) // end colorfilter
Problem is, I can use one filter, and it will display the correct subset of table rows, but when I provide input for the other filter, it doesn't seem to recognize the visible table rows that are remaining from the previous column, but instead it appears that it does an entirely new filtering of the original table. If 10 rows are returned after applying one filter, the 2nd filter should only apply to THOSE 10 rows. I've tried LIVE and BIND, but not working.
Can anyone shed some light on where I'm going wrong? Thanks!
The uiTableFilter plugin doesn't support what you're trying to do. A quick look at the source reveals this:
elems.each(function(){
var elem = jQuery(this);
jQuery.uiTableFilter.has_words(getText(elem), words, false)
? matches(elem)
: noMatch(elem);
});
and that expands to (essentially) this:
elems.each(function(){
var elem = jQuery(this);
jQuery.uiTableFilter.has_words(getText(elem), words, false)
? elem.show()
: elem.hide();
});
So all it does is spin through all the rows, .show() those that match, and .hide() those that don't; uiTableSorter doesn't pay attention to the current shown/hidden state of the rows and there's no way to tell it to filter on multiple columns.
If you really need your desired functionality then you can modify the plugin's behavior (the code is pretty small and simple) or just write your own. Here's a stripped down and simplified version that supports multiple filters and is a more conventional jQuery plugin than uiTableFilter:
(function($) {
$.fn.multiFilter = function(filters) {
var $table = $(this);
return $table.find('tbody > tr').each(function() {
var tr = $(this);
// Make it an array to avoid special cases later.
if(!$.isArray(filters))
filters = [ filters ];
howMany = 0;
for(i = 0, f = filters[0]; i < filters.length; f = filters[++i]) {
var index = 0;
$table.find('thead > tr > th').each(function(i) {
if($(this).text() == f.column) {
index = i;
return false;
}
});
var text = tr.find('td:eq(' + index + ')').text();
if(text.toLowerCase().indexOf(f.word.toLowerCase()) != -1)
++howMany;
}
if(howMany == filters.length)
tr.show();
else
tr.hide();
});
};
})(jQuery);
I'll leave error handling and performance as an exercise for the reader, this is just an illustrative example and I wouldn't want to get in the way of your learning. You could wire it up something like this:
$('#type').keyup(function() {
$('#leeLooDallas').multiFilter({ column: 'petType', word: this.value });
});
$('#color').keyup(function() {
$('#leeLooDallas').multiFilter([
{ column: 'petType', word: $('#type').val() },
{ column: 'petColor', word: this.value }
]);
});
And here's a live example (which assumes that you're going to enter something in "type" before "color"): http://jsfiddle.net/ambiguous/hdFDt/1/
