Currently I have a table that contains all columns that we possibly want to show. What I would like to do is move a subset up to the front and hide all other columns. Basically what it looks like is this:
[Title, Name, DOB, Address, House Type, Salary] etc.
I would like to be able to pass a subset of this list
[Name,House Type, Salary]
and for to sort the list like so
[Name,House Type,Salary,Title,DOB,Address]
However due to the way datatables deals with colReorder it seems like I cannot access the table by title, but instead only by index, which on redraw updates. So I would need to create some sort of map maybe?
According to the docs, you can pass a second parameter to colReorder.order to use the original indexes (instead of the indexes from the last reordering). So, as long as you know the original index of each named column, you will be able to reorder them. Like so:
var originalOrder = [
"Title", "Name", "DOB", "Address", "House Type", "Salary"
];
var getNewOrder = function(columns){
var indexes = [];
// Search for the index of the named column
for (var i = 0; i < columns.length; i++){
indexes.push(originalOrder.indexOf(columns[i]));
}
// Add the rest of indexes in their original order
for (var i = 0; i < originalOrder.length; i++){
if (indexes.indexOf(i) < 0){
indexes.push(i);
}
}
return indexes;
};
// Pass it true so colReorder knows these are original indexes
table.colReorder.order(getNewOrder(["Name","House Type", "Salary"]), true);
You can see a working example here.

For my columns definition.
var columns = [
{id: "label", name: "point", formatter:this.clickableFormatter,field: "point",width: 150},
then I add clickhander for it.
chart.addClickHandler(){
}
Also I use clickableFormatter for this.
clickableFormatter(row,cell,value,columnDef,dataContext){
return "<span style='cursor:pointer;'>" + value + "</span>";
}
From these code. my table rows are clickable and I can show the user where is clickable by changing pointer.
However now I want to make one row unclickable.
(for example total row)
Is it possible to prevent click event for one low??
And is it possible to use another formatter for one row?
I gave the data from for loop and add total seperately.
for (var k = 0 ; k < data.length ;k++){
var temp = new Array();
temp['id'] = data[k]['id'];
temp['point'] = data[k]['point'];
ret.push(temp);
}
ret.push({
'id' : "total",
"point" : pointTotal,
});
In your formatter, you have access to the value of the cell, so if value==='total', just return an empty string.
Also FYI, I don't think you need the for loop in your code (you could just leave it out entirely), unless you're using it to calculate the total, but you don't seem to be doing that.
If you think that you need it for creating the array objects, you're misunderstanding arrays in javascript, what you're actually setting is object properties, and it would be usual to initialise with var temp = { }; rather than as Array.
It may not make sense at first, but everything in javascript is an object, including arrays and functions. So you can add object properties to anything.
somevar[numericVal] = x; // set array element, somevar must be type Array
somevar['stringVal'] = x; // set object property 'stringVal'
somevar.stringVal = x; // identical to above line, different way of specifying
So I have a Table made from some json data...
{
"AKH":{
"name": "Amonkhet",
"code": "AKH"
"cards": [
{
"artist": "Izzy",
"cmc": 3,
"colorIdentity": [
"W"
],
"colors": [
"White"
],
"id": "df3a6e0336684c901358f3ff53ec82ff5d7cdb9d",
"imageName": "gideon of the trials",
"layout": "normal",
"loyalty": 3,
"manaCost": "{1}{W}{W}",
"multiverseid": 426716,
"name": "Gideon of the Trials",
"number": "14",
"rarity": "Mythic Rare",
"subtypes": [
"Gideon"
],
"text": "+1: Until your next turn, prevent all damage target permanent would deal.\n0: Until end of turn, Gideon of the Trials becomes a 4/4 Human Soldier creature with indestructible that's still a planeswalker. Prevent all damage that would be dealt to him this turn.\n0: You get an emblem with \"As long as you control a Gideon planeswalker, you can't lose the game and your opponents can't win the game.\"",
"type": "Planeswalker — Gideon",
"types": [
"Planeswalker"
]
},
The Table row ends up looking like this for each of the cards. at the moment I only Attach the ID, Card name, and Mana Cost to each row
<td><a href="#" onclick="showInfo(this.id)"
id="df3a6e0336684c901358f3ff53ec82ff5d7cdb9d">Gideon of the Trials</a></td>
Now I want to search through these cards. (Keep in mind there are over 17,000 different cards that will be on this list) I can get it to find the things.. But I'm having several different issues... Either it finds them all but doesn't hide the rest of the list, or it hides the whole list and only displays one of the found cards.
So question A... What am I missing to make the search work correctly?
$(document).on('change', 'input[type=checkbox]', function() {
var lis = $('.cardsRow')
$('input[type=checkbox]').filter(':checked').each(function(){
filterKeyB = $(this).attr('id')
filterKeyA = $(this).attr('name')
$.each(json, function(setCode, setListing) {
$.each(setListing.cards,function(cardNum, cardListing){
var x = Object.keys(cardListing)
var y = Object.keys(cardListing).map(function (key){
return cardListing[key]
})
for (i = 0; (i < x.length); i++) {
if(x[i] === filterKeyA){
if (y[i] instanceof Array){
var holder = y[i]
var valueArr =[]
for(var k = 0; k < holder.length; k++){
valueArr = holder.join('|').toLowerCase().split('|')
var foundIt = valueArr.includes(filterKeyB)
}
}else{
var stringy = y[i]
var stringyA= stringy.toLowerCase().replace(/\s/g, '')
if (stringyA === filterKeyB){
var foundIt = true
}
}
if(foundIt === true){
$winner = cardListing.name
for (k = 0; (k < lis.length); k++){
if (lis[k].innerText.indexOf($winner) != -1) {
$(lis[k]).show()
}
}
}
}
}
})
Question B... Since you are already here... Would it be better practice to attach the data that can be searched to the element itself? Maybe just the most searched (Like Name and Mana) and have more advanced queries go through the data again?
I don't understand why the code isn't working or even how it works, it looks like it references some functions that aren't defined in the sample. But I can share with you a really simple/intuitive way to filter stuff, I hope you find it useful.
Native filter method is so useful for what you're trying to do, it takes a callback that takes current element as an arg and returns true or false, if true, the element is included in the new array it produces.
But filter only takes one function, and you have many filters, so let's make a function that combines many filter Fns together into one fn, so you can pass them in all at once:
const combineFilters = (...fns) => val => fns.reduce((prev, curr) => prev || curr(val), false);
OK, how about storing the names of the filter functions as keys in an object so we can reference them using a string? That way we could give each checkbox an ID corresponding to the name of the filter function they are supposed to apply, and makes things really easy to implement (and read):
const filterFns = {
startsWithG(card) {
return card.name[0] === 'G';
},
//etc.
};
OK, time to get the IDs of all the checkboxes that are clicked, then map them into an array of functions.
const filters = $('input[type=checkbox]')
.filter(':checked')
.map((e, i) => $(i).attr('id'))
.get()
.map(fnName => filterFns[fnName])
(Assume the relevant data is stored in a var called...data.) We can use combineFilters combined with filters (array of Fns) to activate all of the relevant filters, then map the resulting array of matching objects into the HTML of your choosing.
const matches = data.cards
.filter(combineFilters(...filters))
.map(card => `<div>${card.name}</div>` );
Then time to update DOM with your matches!
As others have noted, if you need to do any more complicated filtering on objects or arrays, lodash library is your friend!
One of my ng-table columns contains a selectize dropdown. The value of this column is a foreign key for another table. Instead of displaying this key, I wish to display another attribute (name) of the row this key represents.
My data is in an array called table.
I have the dropdown displaying correctly using another array, fkTable.
<selectize ng-model="row[col.name]"
options='fkTable'
config='fkConfig'">
where fkConfig:
$scope.fkConfig = {
maxItems: 1,
valueField: 'id',
labelField: 'name',
searchField: 'name'
};
Now I want to be able to filter and order this column based on the foreign rows name, not id.
I attempted to go about this mapping the ids to their names:
$scope.foreignRowNames = {
0:"not grouped"
1:"Google"
14:"Youtube"
}
and by creating a custom filter for this specific column:
function filterSelectizeColumn(table, searchTerm) {
for (var i = 0; i < table.length; i++) {
var fkValue = table[i].fk;
var foreignRowName = $scope.foreignRowNames[fkValue]];
if (foreignRowName.indexOf(searchTerm) == -1) {
table = table.splice(i, 1);
}
}
}
But this seems an awkward and inefficient way of going about something I would have thought to be a somewhat common problem due to the popularity of the two libraries.
My question is how can I efficiently create a custom filter for this foreign key column.
The solution I went with:
replace all foreign keys with their corresponding name
when making edits, convert names back to the keys they represent
I've got objects 'ing' with a field named 'id' and another one called 'fObj' with a field named 'contain'.
By using ng-repeat i'd like to show only these 'ing' objects where ing.id is a part of fObj.contain
e.g.
ing=[{id: 1,field: value},{id:2, field: othervalue},{id:3, field: cat}];
fObj={field1: value1, field: value2, contain: ':1:3:'};
By having this contain value I'd like to show only ing's with id=1 and id=3
Yeah, I know there are two types of data (number and string) but even if i changed numbers to strings it still didn't work
I just dont't know how to make it works. It's probably some kind of custom filter, but I've tried couples and nothing happend.
I would be glad if you suggest me a solution.
Thanks
In your controller,
var ids = fObj.contain.split(':');
// the array for your ng-repeat
var displayIng = [];
// loop the objects, see if the id exists in the list of id's
// retrieved from the split
for(i = 0; i < ing.length; i++) {
if(ids.indexOf(ing.id.toString()) displayIng.push(ing[i]);
}
I would split the numbers out of fObj.contain; and use them as hashmap object keys for simple filtering of the array
var ing=[{id: 1},{id:2},{id:3}];
var fObj={contain: ':1:3:'};
var IDs = fObj.contain.split(':').reduce(function(a,c){
a[c]=true;
return a;
},{});
// produces {1:true,3:true}
var filtered = ing.filter(function(item){
return IDs[item.id];
});
console.log(filtered)
[
{"task":"test","created":"/Date(1291676980607)/"},

I looked on here, and someone had the same sort of question, but the "checked" correct answer was that it will be different on IE if the item is deleted, which would be fine. My issue is, those items above are stored, but when i go and grab them, iterate, and return, the items are reversed and the created is at the 0 index and task is at 1. Also, i need to return this as JSON.
Here is my basic JS (value == an int the user is passing in):
outputJSON = {};
for(x in json[value]){
outputJSON[x] = _objectRevival(json[value][x]);
}
return outputJSON;
That returns:
created: Mon Dec 06 2010 15:09:40 GMT-0800 (Pacific Standard Time)
task: "test"
The order of the properties of an object is undefined. It is not possible to force them in a specified order. If you need them in a specific order, you can build this structure reliably using arrays:
var values = [
[["task", "test"], ["created", "/Date(1291676980607)/"]],
[["task", "One More Big Test"], ["created", "/Date(1291677246057)/"]],
[["task", "New Task"], ["created", "/Date(1291747764564)/"]]
];
Then you can iterate over your structure like this:
for (var i = 0; i < values.length; i++) {
for (var k = 0; k < values[i]; k++) {
// values[i][k][0] contains the label (index 0)
// values[i][k][1] contains the value (index 1)
}
}
To enforce a particular order for your output just replace json[value] in your for loop with an array of the object properties in the order you want to display them, in your case ["task", "created"].
The problem is that javascript objects don't store their properties in a specific order. Arrays on the other do (hence why you can get something consistent from json[0], json[1], json[2]).
If your objects will always have "task" and "created", then you can get at them in any order you want.
json[value]["task"]
and
json[value]["created"]
Update:
This should work with your existing code.
Before sending the json object:
var before = [
{"task":"test","created":"/Date(1291676980607)/"},
{"task":"One More Big Test","created":"/Date(1291677246057)/"},
{"task":"New Task","created":"/Date(1291747764564)/"}
];
var order = [];
for (var name in before[0]) {
order.push(name); // puts "task", then "created" into order (for this example)
}
Then send your json off to the server. Later when you get the data back from the server:
var outputJSON = {};
for (var x in order) {
if (order.hasOwnProperty(x)) {
outputJSON[order[x]] = _objectRevival(json[value][order[x]]); // I'm not sure what _objectRevival is...do you need it?
}
}
return outputJSON;
var items = ["bag", "book", "pen", "car"];
items.reverse();
This will result in the following output:
car , pen, book, bag
Even if you have JSON array it will reverse.
