I am trying to increment the delay of every data-attribute inside the div element.
See my code
JQUERY
jQuery(document).ready(function($) {
var Column = [], startDelayTime, counter;
Column = $('.col-outside');
startDelayTime = 300;
addDelayTime = 25;
for(var i = 0; i < Column.length; i++) {
Column.attr('data-sal-delay', startDelayTime + addDelayTime[i]);
}
});
HTML:
<div class="col-md-3 col-outside" data-sal="slide-right" data-sal-easing="ease-out-bounce" data-sal-delay="300">
Hopefully someone can explain me what i am doing wrong, or what i have to do.
The logic in your loop needs to look like this. I removed the JQuery logic to simplify the example.
var currentDelay = 300;
var addDelayTime = 25;
for(var i = 0; i < 10; i++) {
// Column.attr('data-sal-delay', currentDelay);
console.log(currentDelay);
currentDelay += addDelayTime;
}
This will work:
You need to multiply by i on delayStart to get desired effect.
$(function() {
var Column = [], startDelayTime, counter;
Column = $('.col-outside');
startDelayTime = 300;
addDelayTime = 25;
Column.each(function(i, c){
$(c).attr('data-sal-delay', startDelayTime+ (addDelayTime*i));
});
});
You need to do two things:
Use the current column in your loop (Column[i] rather than Column).
Increment the value of startDelayTime every time the loop iterates.
Here's your edited code:
jQuery(document).ready(function($) {
var Column = [], startDelayTime, counter;
Column = $('.col-outside');
startDelayTime = 300;
addDelayTime = 25;
for(var i = 0; i < Column.length; i++) {
Column[i].attr('data-sal-delay', startDelayTime + addDelayTime);
startDelayTime += addDelayTime;
}
});
Now your code should work. Hopefully this helps!
There are a few problems with your code.
Within your loop, you need to access the single column node using Column[i] in order to set an attribute.
attr() is a jQuery method, so you need to use it on a jQuery selection like $(Column[i]).attr(name, value). Or you could just use the javascript method setAttribute like Column[i].setAttribute(name, value)
addDelayTime is an integer so addDelayTime[i] is undefined. What you want to do here instead is multiply addDelayTime by the current array index. addDelayTime * i
In this example I've fixed the above 3 issues and instead of a for loop I've used jQuery's each to iterate over the columns.
jQuery(document).ready(function($) {
var startDelayTime = 300;
var addDelayTime = 25;
$.each($(".col-outside"), function(index, item) {
$(item).attr("data-sal-delay", startDelayTime + index * addDelayTime);
});
});
.col-outside::after {
content: attr(data-sal-delay);
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="col-outside"></div>
<div class="col-outside"></div>
<div class="col-outside"></div>
<div class="col-outside"></div>
<div class="col-outside"></div>
As shown in the image below, I have several div inside a div (outer div). I need to count the number of rows the outer div have. In this example the row count is 5.
Note:The inner div is floated left and its content is created dynamically.
Does anyone has any ideas?
Perhaps something along the lines of:
Demo Fiddle
var minLeft = null, rows = 0;
$('div div').each(function () {
var left = $(this).offset().left;
if (left <= minLeft || minLeft==null) {
rows++;
minLeft=left;
}
});
console.log(rows);
Try with something like this:
var parentX = $('#containerDiv').position().left;
var rows = 0;
$('#containerDiv div').each(function(){
if( $(this).position().left == parentX ){
++rows;
}
});
alert('Num of rows: ' + rows );
I'm trying to make a script to make my applications tables more mobile friendly.
The tables are all very similar, but very in number of row and columns, since they will be dynamically created, I'll have little control over this, so i've come up with the script below, it almost works but one function is not be passed on to each table, it stops after the first.
I suggest looking at the js fiddle: http://jsfiddle.net/e4vC3/1/
Here is the piece of the script that is not working correctly:
// Create content for new headers in mobile table by copying from original table
var HeaderArray = [];
$("table thead tr th").each(function(){
var innerArray = [];
$(this).each(function () {
innerArray.push($(this).text());
});
HeaderArray.push(innerArray); // Put content for new headers in array
});
$("table.mobile_table tbody tr").each(function(index, elem){ // Place content of array where array position and row index are the same
$(this).find("td").first().text(HeaderArray[index]);
});
Again, if you check the fiddle, you will see that the first arry stops copying objects after the first table, i cant get it to run all the way thought.
If anyone could help me with them, i would really, realy appreciate it..... http://jsfiddle.net/e4vC3/1/
The problem is that there are multiple data rows while only 1 header row. So, you will have to use mod operator like this(index has been replaced with index % TableSize):
$("table.mobile_table tbody tr").each(function(index, elem){ // Place content of array where array position and row index are the same
$(this).find("td").first().text(HeaderArray[index % TableSize]);
});
Updated your code # http://jsfiddle.net/souviiik/e4vC3/4/, see if this is helpful. For the first mobile_table I was not able to put the TH values, I hope you can modify my code :)
var TableSize = $("#ContactsPhoneTable .tableHedaer").size(); // Get # of columns
var i = 1;
var TableRowCount = $(".no_edit").size(); // Get # of body rows
$(".tableHedaer").each(function () {
$(this).attr("id", i++); // Give headers incrementing ID
});
for (var CreateTables = 1; CreateTables < TableRowCount; CreateTables++) { // Create new table class="mobile_table" for each row
$("table").after("<table class='mobile_table'></table>");
}
for(var i = 0 ; i < TableSize ; i++)
{
var tableRow = $("<tr/>").appendTo(".mobile_table");
for(var j = 0 ; j < TableRowCount ; j++)
{
var cellValue = $("#ContactsPhoneTable").find("tr").eq(i).find("td").eq(j).text();
$("<td/>", {
text: cellValue
}).appendTo(tableRow);
}
}
Updated code is at http://jsfiddle.net/souviiik/b6QZT/2/, see if this is acceptable. The code is as below.
var columnCount = $("table thead tr th").not("table.mobile_table thead tr th").size(); // Get # of columns
var rowCount = $("table tbody tr").size(); // Get # of body rows
for (var CreateTables = 0; CreateTables < rowCount; CreateTables++) { // Create new table class="mobile_table" for each row
$("<table/>", {
"class": "mobile_table"
}).appendTo(".newTableContainer");
}
var tableHedaers = [];
for(var th = 0 ; th < columnCount ; th++)
{
tableHedaers.push($(".sortable th").eq(th).text());
}
$(".mobile_table").each(function(idx){
var thisTable = $(this);
for(var i = 0 ; i < columnCount ; i++)
{
var thisTableRow = $("<tr/>").appendTo(thisTable);
for(var j = 0 ; j < 2 ; j++)
{
if(j == 0)
{
$("<td/>", {
"text": tableHedaers[i],
"style": "font-weight: 700"
}).appendTo(thisTableRow);
}
else
{
var cellValue = $("#ContactsPhoneTable").find("tr").eq(idx+1).find("td").eq(i).text();
$("<td/>", {
"text": cellValue
}).appendTo(thisTableRow);
}
}
}
});
I have a table containing cells with rowspan attributes, I would like to:
Whenever a tr is hidden, the table will rearrange itself correctly
Whenever a tr is shown again, it will be restored to original state
So if you have a table like this clicking on X shouldn't destroy the layout.
and click a come back button, should restore the original layout.
(try removing all rows from bottom-up, and than restoring them from right-to-left, this is a desired flow)
I had some semi-solutions, but all seem too complicated, and i'm sure there is a nice way to handle this.
OK I really spent a hell of a long time over this question, so here goes...
For those of you who just want to see the working solution, click here
Update: I've changed the visual columns calculation method to iterate over the table and create a 2-dimensional array, to see the old method which used the jQuery offset() method, click here. The code is shorter, but more time costly.
The problem exists because when we hide a row, whilst we want all the cells to be hidden, we want the pseudo-cells — that is, the cells that appear to be in the following rows due to the cells rowspan attribute — to persist. To get around this, whenever we come across a hidden cell with a rowspan, we try to move it down the the next visible row (decrementing it's rowspan value as we go). With either our original cell or it's clone, we then iterate down the table once more for every row that would contain a pseudo-cell, and if the row is hidden we decrement the rowspan again. (To understand why, look at the working example, and note that when the blue row is hidden, red cell 9's rowspan must be reduced from 2 to 1, else it would push green 9 right).
With that in mind, we must apply the following function whenever rows are shown/hidden:
function calculate_rowspans() {
// Remove all temporary cells
$(".tmp").remove();
// We don't care about the last row
// If it's hidden, it's cells can't go anywhere else
$("tr").not(":last").each(function() {
var $tr = $(this);
// Iterate over all non-tmp cells with a rowspan
$("td[rowspan]:not(.tmp)", $tr).each(function() {
$td = $(this);
var $rows_down = $tr;
var new_rowspan = 1;
// If the cell is visible then we don't need to create a copy
if($td.is(":visible")) {
// Traverse down the table given the rowspan
for(var i = 0; i < $td.data("rowspan") - 1; i ++) {
$rows_down = $rows_down.next();
// If our cell's row is visible then it can have a rowspan
if($rows_down.is(":visible")) {
new_rowspan ++;
}
}
// Set our rowspan value
$td.attr("rowspan", new_rowspan);
}
else {
// We'll normally create a copy, unless all of the rows
// that the cell would cover are hidden
var $copy = false;
// Iterate down over all rows the cell would normally cover
for(var i = 0; i < $td.data("rowspan") - 1; i ++) {
$rows_down = $rows_down.next();
// We only consider visible rows
if($rows_down.is(":visible")) {
// If first visible row, create a copy
if(!$copy) {
$copy = $td.clone(true).addClass("tmp");
// You could do this 1000 better ways, using classes e.g
$copy.css({
"background-color": $td.parent().css("background-color")
});
// Insert the copy where the original would normally be
// by positioning it relative to it's columns data value
var $before = $("td", $rows_down).filter(function() {
return $(this).data("column") > $copy.data("column");
});
if($before.length) $before.eq(0).before($copy);
else $(".delete-cell", $rows_down).before($copy);
}
// For all other visible rows, increment the rowspan
else new_rowspan ++;
}
}
// If we made a copy then set the rowspan value
if(copy) copy.attr("rowspan", new_rowspan);
}
});
});
}
The next, really difficult part of the question is calculating at which index to place the copies of the cells within the row. Note in the example, blue cell 2 has an actual index within its row of 0, i.e. it's the first actual cell within the row, however we can see that visually it lies in column 2 (0-indexed).
I took the approach of calculating this only once, as soon as the document is loaded. I then store this value as a data attribute of the cell, so that I can position a copy of it in the right place (I've had many Eureka moments on this one, and made many pages of notes!). To do this calculation, I ended up constructing a 2-dimensional Array matrix which keeps track of all of the used-visual columns. At the same time, I store the cells original rowspan value, as this will change with hiding/showing rows:
function get_cell_data() {
var matrix = [];
$("tr").each(function(i) {
var $cells_in_row = $("td", this);
// If doesn't exist, create array for row
if(!matrix[i]) matrix[i] = [];
$cells_in_row.each(function(j) {
// CALCULATE VISUAL COLUMN
// Store progress in matrix
var column = next_column(matrix[i]);
// Store it in data to use later
$(this).data("column", column);
// Consume this space
matrix[i][column] = "x";
// If the cell has a rowspan, consume space across
// Other rows by iterating down
if($(this).attr("rowspan")) {
// Store rowspan in data, so it's not lost
var rowspan = parseInt($(this).attr("rowspan"));
$(this).data("rowspan", rowspan);
for(var x = 1; x < rowspan; x++) {
// If this row doesn't yet exist, create it
if(!matrix[i+x]) matrix[i+x] = [];
matrix[i+x][column] = "x";
}
}
});
});
// Calculate the next empty column in our array
// Note that our array will be sparse at times, and
// so we need to fill the first empty index or push to end
function next_column(ar) {
for(var next = 0; next < ar.length; next ++) {
if(!ar[next]) return next;
}
return next;
}
}
Then simply apply this on page load:
$(document).ready(function() {
get_cell_data();
});
(Note: whilst the code here is longer than my jQuery .offset() alternative, it's probably quicker to calculate. Please correct me if I'm wrong).
Working solution - http://codepen.io/jmarroyave/pen/eLkst
This is basically the same solution that i presented before, i just changed how to get the column index to remove the restriction of the jquery.position, and did some refactor to the code.
function layoutInitialize(tableId){
var layout = String();
var maxCols, maxRows, pos, i, rowspan, idx, xy;
maxCols = $(tableId + ' tr').first().children().length;
maxRows = $(tableId + ' tr').length;
// Initialize the layout matrix
for(i = 0; i < (maxCols * maxRows); i++){
layout += '?';
}
// Initialize cell data
$(tableId + ' td').each(function() {
$(this).addClass($(this).parent().attr('color_class'));
rowspan = 1;
if($(this).attr('rowspan')){
rowspan = $(this).attr("rowspan");
$(this).data("rowspan", rowspan);
}
// Look for the next position available
idx = layout.indexOf('?');
pos = {x:idx % maxCols, y:Math.floor(idx / maxCols)};
// store the column index in the cell for future reposition
$(this).data('column', pos.x);
for(i = 0; i < rowspan; i++){
// Mark this position as not available
xy = (maxCols * pos.y) + pos.x
layout = layout.substr(0, xy + (i * maxCols)) + 'X' + layout.substr(xy + (i * maxCols) + 1);
}
});
}
Solution: with jquery.position() - http://codepen.io/jmarroyave/pen/rftdy
This is an alternative solution, it assumes that the first row contains all the information about the number of the table columns and the position of each on.
This aproach has the restriction that the inizialitation code must be call when the table is visible, because it depends on the visible position of the columns.
If this is not an issue, hope it works for you
Initialization
// Initialize cell data
$('td').each(function() {
$(this).addClass($(this).parent().attr('color_class'));
$(this).data('posx', $(this).position().left);
if($(this).attr('rowspan')){
$(this).data("rowspan", $(this).attr("rowspan"));
}
});
UPDATE
According to this post ensuring the visibility of the table can be manage with
$('table').show();
// Initialize cell data
$('td').each(function() {
$(this).addClass($(this).parent().attr('color_class'));
$(this).data('posx', $(this).position().left);
if($(this).attr('rowspan')){
$(this).data("rowspan", $(this).attr("rowspan"));
}
});
$('table').hide();
As Ian said, the main issue to solve in this problem is to calculate the position of the cells when merging the hidden with the visible rows.
I tried to figure it out how the browser implements that funcionality and how to work with that. Then looking the DOM i searched for something like columnVisiblePosition and i found the position attributes and took that way
function getColumnVisiblePostion($firstRow, $cell){
var tdsFirstRow = $firstRow.children();
for(var i = 0; i < tdsFirstRow.length; i++){
if($(tdsFirstRow[i]).data('posx') == $cell.data('posx')){
return i;
}
}
}
The js code
$(document).ready(function () {
add_delete_buttons();
$(window).on("tr_gone", function (e, tr) {
add_come_back_button(tr);
});
// Initialize cell data
$('td').each(function() {
$(this).addClass($(this).parent().attr('color_class'));
$(this).data('posx', $(this).position().left);
if($(this).attr('rowspan')){
$(this).data("rowspan", $(this).attr("rowspan"));
}
});
});
function calculate_max_rowspans() {
// Remove all temporary cells
$(".tmp").remove();
// Get all rows
var trs = $('tr'), tds, tdsTarget,
$tr, $trTarget, $td, $trFirst,
cellPos, cellTargetPos, i;
// Get the first row, this is the layout reference
$trFirst = $('tr').first();
// Iterate through all rows
for(var rowIdx = 0; rowIdx < trs.length; rowIdx++){
$tr = $(trs[rowIdx]);
$trTarget = $(trs[rowIdx+1]);
tds = $tr.children();
// For each cell in row
for(cellIdx = 0; cellIdx < tds.length; cellIdx++){
$td = $(tds[cellIdx]);
// Find which one has a rowspan
if($td.data('rowspan')){
var rowspan = Number($td.data('rowspan'));
// Evaluate how the rowspan should be display in the current state
// verify if the cell with rowspan has some hidden rows
for(i = rowIdx; i < (rowIdx + Number($td.data('rowspan'))); i++){
if(!$(trs[i]).is(':visible')){
rowspan--;
}
}
$td.attr('rowspan', rowspan);
// if the cell doesn't have rows hidden within, evaluate the next cell
if(rowspan == $td.data('rowspan')) continue;
// If this row is hidden copy the values to the next row
if(!$tr.is(':visible') && rowspan > 0) {
$clone = $td.clone();
// right now, the script doesn't care about copying data,
// but here is the place to implement it
$clone.data('rowspan', $td.data('rowspan') - 1);
$clone.data('posx', $td.data('posx'));
$clone.attr('rowspan', rowspan);
$clone.addClass('tmp');
// Insert the temp node in the correct position
// Get the current cell position
cellPos = getColumnVisiblePostion($trFirst, $td);
// if is the last just append it
if(cellPos == $trFirst.children().length - 1){
$trTarget.append($clone);
}
// Otherwise, insert it before its closer sibling
else {
tdsTarget = $trTarget.children();
for(i = 0; i < tdsTarget.length; i++){
cellTargetPos = getColumnVisiblePostion($trFirst, $(tdsTarget[i]));
if(cellPos < cellTargetPos){
$(tdsTarget[i]).before($clone);
break;
}
}
}
}
}
}
// remove tmp nodes from the previous row
if(rowIdx > 0){
$tr = $(trs[rowIdx-1]);
if(!$tr.is(':visible')){
$tr.children(".tmp").remove();
}
}
}
}
// this function calculates the position of a column
// based on the visible position
function getColumnVisiblePostion($firstRow, $cell){
var tdsFirstRow = $firstRow.children();
for(var i = 0; i < tdsFirstRow.length; i++){
if($(tdsFirstRow[i]).data('posx') == $cell.data('posx')){

if you have any questions or comments let me know.
I'm assuming you want the the rows to shift upward when you hide the row but you do not want the cells to shift left.
Here is what I got http://codepen.io/anon/pen/prDcK
I added two css rules:
#come_back_container{height: 30px;}
td[rowspan='0']{background-color: white;}
Here is the html I used:
<div id="come_back_container"></div>
<table id="dynamic_table" cellpadding=7></table>
<table id="dynamic_table2" cellpadding=7>
<tr style="background-color: red">
<td rowspan="5">a</td>
<td rowspan="1">b</td>
<td rowspan="5">c</td>
<td rowspan="1">d</td>
<td rowspan="2">e</td>
</tr>
<tr style="background-color: grey">
<td rowspan="0">f</td>
<td rowspan="1">g</td>
<td rowspan="0">h</td>
<td rowspan="1">i</td>
<td rowspan="0">j</td>
</tr>
<tr style="background-color: blue">
<td rowspan="0">k</td>
<td rowspan="1">l</td>
<td rowspan="0">m</td>
<td rowspan="1">n</td>
<td rowspan="1">o</td>
</tr>
<tr style="background-color: yellow">
<td rowspan="0">p</td>
<td rowspan="1">q</td>
<td rowspan="0">r</td>
<td rowspan="1">s</td>
<td rowspan="2">t</td>
</tr>
<tr style="background-color: green">
<td rowspan="0">u</td>
<td rowspan="1">v</td>
<td rowspan="0">w</td>
<td rowspan="1">x</td>
<td rowspan="0">y</td>
</tr>
</table>
The first rule is just to keep the top edge of the table in the same place. The second rule is to make the cells appear blank by blending in with the background, so change accordingly.
Finally here is the js:

I tried to use clear variable and method names but if you have any quests just ask.
PS- I know there is no easy way to add content to the cells right now but you only asked for disappearing rows.
jqGrid has column named Posted. It can be positioned in different positions depending how grid is configured by customer but is always prssent.
I need to change background color of rows if Posted column has value True
I tried colmodel below but alert(rdata.Posted) displays always undefined.
How to change backgound color of row if Posted column in this row has value true ?
I looked into lot of Oleg and other solutions for changing background color but they are using hard coded column number.
colModel: [
{"cellattr":function(rowId, tv, rawObject, cm, rdata) {
if (rdata.Posted)
return 'class="jqgrid-readonlycolumn"';
return '';
}
,"label":"Klient","name":"Klient_nimi","classes":null,"hidden":false},
{"label":null,"name":"Posted","editable":true,"width":0,
"classes":null,"hidden":true}],
...
Update
In update2 Oleg recommends to use rowattr. I need to hide inlined delete button and custom post button in actions column also. I'm usijng code below in loadComplete. How to implement this using rowattr ?
var LoadCompleteHandler = function () {
var iCol = getColumnIndexByName($grid, 'Kinnitatud'),
postedDateCol = getColumnIndexByName($grid, 'Kinkuup'),
cRows = $grid[0].rows.length,
iRow,
row,
className,
isPosted,
mycell,
mycelldata,
i, count,
cm = $grid.jqGrid('getGridParam', 'colModel'),
l,
iActionsCol = getColumnIndexByName($grid, '_actions');
l = cm.length;
if (iCol > 0 || postedDateCol > 0) {
for (iRow = 0; iRow < cRows; iRow = iRow + 1) {
row = $grid[0].rows[iRow];
className = row.className;
isPosted = false;
if ($.inArray('jqgrow', className.split(' ')) > 0) { // $(row).hasClass('jqgrow')
if (iCol > 0) {
isPosted = $(row.cells[iCol]).find(">div>input:checked").length > 0;
}
if (postedDateCol > 0) {
mycell = row.cells[postedDateCol];
mycelldata = mycell.textContent || mycell.innerText;
isPosted = mycelldata.replace(/^\s+/g, "").replace(/\s+$/g, "") !== "";
}
if (isPosted) {
if ($.inArray('jqgrid-postedrow', className.split(' ')) === -1) {
row.className = className + ' jqgrid-postedrow';
$(row.cells[iActionsCol]).find(">div>div.ui-inline-del").hide();
$(row.cells[iActionsCol]).find(">div>div.ui-inline-post").hide();
}
}
}
}
}
The main ideas to change the background color of the row you will find here and here. I recommend you to read this answer which discussed different advantages and disadvantages of different approaches.
To get column index from the column name you can use following simple function:
var getColumnIndexByName = function(grid, columnName) {
var cm = grid.jqGrid('getGridParam','colModel'),i=0,l=cm.length;
for (; i<l; i++) {
if (cm[i].name===columnName) {
return i; // return the index
}
}
return -1;
};
The function getColumnIndexByName($("#list"), 'MyColumnName') will get you the index in colModel of the 'MyColumnName' column.
To change the background color you can follow the example
loadComplete: function() {
$("tr.jqgrow:odd").addClass('myAltRowClass');
}
from the answer, but instead of ':odd' filter you can write the filter yourself using jQuery.filter. Inside of the filter you can use :nth-child() to access the data from the corresponding <td> element (see here)
UPDATED: You can do the following (very close to the code from the another answer):
loadComplete: function() {
var iCol = getColumnIndexByName($(this),'closed'),
cRows = this.rows.length, iRow, row, className;
for (iRow=0; iRow<cRows; iRow++) {
row = this.rows[iRow];
className = row.className;
if ($.inArray('jqgrow', className.split(' ')) > 0) {
var x = $(row.cells[iCol]).children("input:checked");
if (x.length>0) {
if ($.inArray('myAltRowClass', className.split(' ')) === -1) {
row.className = className + ' myAltRowClass';
}
}
}
}
}
The corresponding demo is here. You will see the following:
By the way if the 'Closed' column will be hidden everything will continue to work as before.
UPDATED 2: The answer describe how to use rowattr callback to simplify the solution and to have the best performance (in case of gridview: true).
I think the answer is right here: http://www.trirand.net/forum/default.aspx?g=posts&m=2678
Let me know if this is wat you need.
Best Regards.
