Merging 4 similar click functions into one - javascript

Here are 4 functions I use to improve the usability of a table by:
If cell contains a checkbox and you click outside of a checkbox
The the tr contains data-url then the whole row is "clickable"
with CSS hover effect and redirects on click.
If the last column in the table contains a relative/absolute URL
then also redirects on click.
Check all checkboxes.
Here's my code:
// Click table cell auto check checkbox
$('table tr td').has("input[type=checkbox]").click(function(event) {
// Onl call this if click outside of the checkbox itself
if (event.target.type !== 'checkbox') {
$(':checkbox', this).trigger('click');
}
});
// Table row click
$('table tr[data-url]').each(function(){
var url = $(this).attr("data-url");
if(url.length){
$(this)
.addClass("clickable")
.find("td").click(function(){
window.location = url;
return false;
});
}
});
// Double click row, open edit link
$('table:not(.noDoubleClick) tr td').dblclick(function(e) {
var linkEl = $(this).parents('tr').find('td:last-child a');
var linkElHref = linkEl.attr('href');
// Check if has href and http protocol
if(!linkElHref.length || linkEl.prop('protocol').indexOf("http") !== 0){
e.preventDefault();
return false;
}
if (linkElHref && linkEl.attr('onclick') === undefined && !linkEl.hasClass("popme")) {
document.location = linkElHref;
} else {
linkEl.click();
}
});
// Check all checkboxes
$('table input[type=checkbox][name^="checkall"]').live("click",function() {
var parent = $(this).parents('table');
if(!$(this).parents('table').length){
parent = $(this).parents("form");
}
parent.find(':checkbox[name^="' + $(this).attr("data-name") + '"]').prop("checked", this.checked);
});
Q: how can I modify this into one function so that jquery only has to search for tables once?
Example jsfiddle
Thanks for every bodies suggestions I have ended up taking a slightly different approach:
$('table').each(function(){
var $table= $(this), $cell, $row;
// TABLE ROWS
$table.find('tr').each(function(){
$row = $(this);
// Row click redirect to data-url
var url = $row.attr("data-url");
if(url && url.length){
$row.addClass("clickable").find("td").click(function(){
window.location = url;
return false;
});
}
// TABLE HEADING CELLS
$row.find('th, thead td').each(function(){
$cell = $(this);
// Check all checkboxes
$cell.find('input.checkall').live("click",function() {
var parent = $(this).parents('table');
if(!$(this).parents('table').length){
parent = $(this).parents("form");
}
parent.find(':checkbox[name^="' + $(this).attr("data-name") + '"]').prop("checked", this.checked);
});
});
// TABLE CELLS
$row.find('td').each(function(){
$cell = $(this);
// Check checbox onClick
if($cell.find("input[type=checkbox]")){
$cell.click(function(e) {
if(e.target.type !== 'checkbox') $(':checkbox', this).trigger('click');
});
}
// Double click open edit link
if(!$table.hasClass("noDoubleClick")){
$cell.dblclick(function(e){
var linkEl = $(this).parents('tr').find('td:last-child a');
var linkElHref = linkEl.attr('href');
// Check if has href and http protocol
if(linkElHref && (!linkElHref.length || linkEl.prop('protocol').indexOf("http") !== 0)){
e.preventDefault();
return false;
}
if (linkElHref && linkEl.attr('onclick') === undefined && !linkEl.hasClass("popme")) {
document.location = linkElHref;
} else {
linkEl.click();
}
});
}
}); // end CELLS
}); // end ROWS
}); // end TABLE

You should use .on , .live is being deprecated:
$(document).on('click', 'table tr td', function(event)
{
if( $(this).has("input[type=checkbox]"))
{
if (event.target.type !== 'checkbox')
$(':checkbox', this).trigger('click');
}
});
// Table row click
$(document).on('click', 'table tr[data-url] td', function(e)
{
var url = $(this).parent().attr("data-url");
if(url.length)
{
window.location = url;
return false;
}
});
$(document).on('dblclick', 'table:not(.noDoubleClick) tr td', function(e) {
debugger;
var linkEl = $(this).parents('tr').find('td:last-child a');
var linkElHref = linkEl.attr('href');
// Check if has href and http protocol
if(!linkElHref.length || linkEl.prop('protocol').indexOf("http") !== 0){
e.preventDefault();
return false;
}
if (linkElHref && linkEl.attr('onclick') === undefined && !linkEl.hasClass("popme")) {
document.location = linkElHref;
} else {
linkEl.click();
}
});
// Check all checkboxes
$(document).on('click', 'table input.checkall', function() {
var parent = $(this).parents('table');
if(!$(this).parents('table').length){
parent = $(this).parents("form");
}
parent.find(':checkbox[name^="' + $(this).attr("data-name") + '"]').prop("checked", this.checked);
});​

I have made the basic stubs here, i dont want to rewrite all your code.
$(document).ready(function(){
$('table').each(function(){
var table = $(this);
table.find('tr').each(function (){
var tr = $(this);
tr.find('td').each(function(){
var td = $(this);
td.has("input[type=checkbox]").click(function(event) {
// Only call this if click outside of the checkbox itself
if (event.target.type !== 'checkbox') {
$(':checkbox', this).trigger('click');
}
});
});
});
});
});
​
The logic is: Find all tables, loop through all the tr's and then the td's. I've did your first function and hope that explains how it could be used?
​

The best thing to do in this case is to:
Get all of the tables in the page
Loop through each table
Find and apply logic to the individual elements as needed
$('table').each(function(){
var table = $(this),
rows = table.find('tr[data-url]'),
cells = table.find('td'),
all = table.find('input[type=checkbox][name^="checkall"]'),
edit = table.is('.noDoubleClick');
cells.each(function(){
//Apply your logic here
if(edit === true){
//Apply your logic to this cell here
}
});
rows.each(function(){
//Apply your logic to this row here
});
all.on('click',function(){
//Apply your logic here
});
});

Option to check all boxes and hide table row elements

I've created a simple table where I have the option to select all checkboxes. I would like to have the option to hide individual rows, or hide all the rows when using the select all function. I've managed to get the checkboxes working, but I can't figure out why the table isn't responding to the action. I appreciate any help or insight.
The full code is in this Fiddle. Here is a glance at the jquery and javascript:
<script>
$(document).ready(function() {
$('input[type="checkbox"]').change(function() {
var inputValue = $(this).attr("value");
$("." + inputValue).toggle();
});
});
</script>
<script>
function checkedAll() {
var elements = this.form.getElementsByTagName('input');
// iterate and change status
for (var i = elements.length; i--;) {
if (elements[i].type == 'checkbox') {
elements[i].checked = this.checked;
}
}
}
</script>
<script>
$(document).ready(function() {
$('input[type="checkbox"]').change(function() {
var inputValue = $(this).attr("value");
var checked = $(this)[0].checked;
$("tr").each(function() {
if($(this).find("td:eq(0)").html() === inputValue.toString()) { // this checks the first cell of each row of the table for a match
if(checked) { //instead of just toggling, you check the status and then show/hide
$(this).hide();
} else {
$(this).show();
}
}
});
});
});
</script>
<script>
function checkedAll() {
var elements = this.form.getElementsByTagName('input');
// iterate and change status
for (var i = elements.length; i--;) {
if (elements[i].type == 'checkbox') {
elements[i].checked = this.checked;
$(elements[i]).trigger("change"); // this triggers the function above
}
}
}
</script>
This should work for you. The .each loop will iterate through the rows and hide the ones where the first td is the value to be hidden.

JavaScript not working with dynamically loaded gridview

I'm using this javascript on several pages to filter gridview results based on the input, and it works perfectly. However, on the one page where I'm dynamically generating columns for the gridview it does not work.
I tried using $('.btnSearch').on('click','.gvSearch', function (e) {...
,but that also didn't work.
$(document).ready(function () {
$('.lblSearch').css('display', 'none');
$('.btnSearch').click(function (e) {
// Hide No records to display label.
$('.lblSearch').css('display', 'none');
//Hide all the rows.
$(".gvSearch" + " tr:has(td)").hide();
var iCounter = 0;
//Get the search box value
var sSearchTerm = $('.txtSearch').val();
//if nothing is entered then show all the rows.
if (sSearchTerm.length == 0) {
$(".gvSearch" + " tr:has(td)").show();
return false;
}
//Iterate through all the td.
$(".gvSearch" + " tr:has(td)").children().each(function () {
var cellText = $(this).text().toLowerCase();
//Check if data matches
if (cellText.indexOf(sSearchTerm.toLowerCase()) >= 0) {
$(this).parent().show();
iCounter++;
return true;
}
});
if (iCounter == 0) {
$('.lblSearch').css('display', '');
}
e.preventDefault();
})
});

jquery clone not working if user select other from the drop down the current text field disabled false

Working on jquery clone with my current code everthing works fine.
first scenario if user select other from the drop down the text
field gets enabled
Second scenario if user click addmore button div gets clone
perfectly with id when user select other both Original and clone
textfield gets enabled actually it should be only the cloned should
get enabled not the enabled
Here is the current Jquery code
var i=1;
$(document).on("click", ".edu_add_button", function () {
var i=$('.cloned-row1').length;
$(".cloned-row1:last").clone(true).insertAfter(".cloned-row1:last").attr({
'id': function(_, id) { return id + i },
'name': function(_, name) { return name + i }
}).end().find('[id]').val('').attr({ 'id': function(_, id) { return id + i }
});
$(".cloned-row1:last").find(".school_Name").attr('disabled', true).val('');
if(i < $('.cloned-row1').length){
$(this).closest(".edu_add_button").removeClass('btn_more edu_add_button').addClass('btn_less btn_less1');
}
i++;
return false;
});
$(document).on('click', ".btn_less1", function (){
var len = $('.cloned-row1').length;
if(len>1){
$(this).closest(".cloned-row1").remove();
}
});
$(document).on('change', '.txt_schName', function (){
var cur = $('.txt_schName').index($(this));
$('.school_Name').eq(cur).val($(this).val())
if ($(this).val() == "other") {
$(".school_Name").prop('disabled', false);
$(".school_Name").val('');
}else{
$(".school_Name").prop('disabled', true);
}
});
$(document).on('change', '.txt_degreName', function (){
var cur = $('.txt_degreName').index($(this));
$('.degree_Description').eq(cur).val($(this).val())
if ($(this).val() == "other") {
$("#degree_Description").prop('disabled', false);
$("#degree_Description").val('');
}else{
$("#degree_Description").prop('disabled', true);
}
});
Here is the fiddle link
Kindly suggest me

DEMO
The issue comes be cause you are using class selector directly. You need apply value only to the text box which belongs in the same container. Use closest() to find the parent.
$(document).on('change', '.txt_schName', function (){
var cur = $('.txt_schName').index($(this));
var container = $(this).closest('.container-fluid');
$('.school_Name').eq(cur).val($(this).val())
if ($(this).val() == "other") {
$(".school_Name", container).prop('disabled', false);
$(".school_Name", container).val('');
}else{
$(".school_Name", container).prop('disabled', true);
}
});
DEMO HERE
You need to refer proper element that has to be disabled and enabled.
Take the sibling of select's parent and find the input element to be disabled as below:
$(document).on('change', '.txt_schName', function (){
var cur = $('.txt_schName').index($(this));
$(this).closest('.col-xs-6').next('.col-xs-6').find('.school_Name').eq(cur).val($(this).val())
if ($(this).val() == "other") {
$(this).closest('.col-xs-6').next('.col-xs-6').find(".school_Name").prop('disabled', false);
$(this).closest('.col-xs-6').next('.col-xs-6').find(".school_Name").val('');
}else{
$(this).closest('.col-xs-6').next('.col-xs-6').find(".school_Name").prop('disabled', true);
}
});
From what you did, you actually change every fields with class .school_Name, to achieve what you want you can add $(this).parents(".row").find(".class_name") so it only change the current div.
$(document).on('change', '.txt_schName', function (){
var cur = $('.txt_schName').index($(this));
$('.school_Name').eq(cur).val($(this).val())
if ($(this).val() == "other") {
$(this).parents(".row").find(".school_Name").prop('disabled', false);
$(this).parents(".row").find(".school_Name").val('');
}else{
$(this).parents(".row").find(".school_Name").prop('disabled', true);
}
});
DEMO HERE
You can do it this way with targeting specific item using parent() and next() selector and also i prefer to access specific field instead of index(such as eq) for input.
var schoolObj = $(this).parent().next().find(".school_Name");
schoolObj.val($(this).val());
if ($(this).val() == "other") {
schoolObj.prop('disabled', false);
schoolObj.val('');
} else {
schoolObj.prop('disabled', true);
}
Here is the Fiddle
You can have a look for jquery traversing:

Next: https://api.jquery.com/next/
Find: https://api.jquery.com/find/

Reset button for JQuery table row filter

I have a table on my page, and a filtering text box above it that works fantastic, using the following JQuery:
$("#searchInputCompanies").keyup(function () {
//split the current value of searchInput
var data = this.value.split(" ");
//create a jquery object of the rows
var jo = $("#cBody").find("tr");
if (this.value == "") {
jo.show();
return;
}
//hide all the rows
jo.hide();
//Recusively filter the jquery object to get results.
jo.filter(function(i, v) {
var $t = $(this);
for (var d = 0; d < data.length; ++d) {
if ($t.text().toLowerCase().indexOf(data[d].toLowerCase()) > -1) {
return true;
}
}
return false;
})
//show the rows that match.
.show();
$('#selectAllCompanies').prop('checked', '');
}).focus(function () {
this.value = "";
$(this).css({
"color": "black"
});
$(this).unbind('focus');
}).css({
"color": "#C0C0C0"
});
How can I set up a Reset Filter button for this?
Uhh, this is quite a bad implementation :(
First, you need to change the event for $("#searchInputCompanies") to make it all a bit easier. So, it will become $("#searchInputCompanies").on("input", function() {...
$("#resetAction").on("whatEventYouWant", function() {
$("#searchInputCompanies").val("").trigger("input");
});
This will trigger input event on $("#searchInputCompanies") and because the text box is empty all rows will become visible.

Jquery: hiding empty table rows

I am trying to write a script that detects if a tables tds are empty and if they are hide the parent tr
I've searched Stack Overflow and found other scripts but none seem to work for me.
So far I have:
$(".table tr").each(function() {
var cell = $(this).find('td').html();
if (cell == null){
console.log('empty');
$(this).parent().addClass('nodisplay');
}
});
but just can't get it working. Any advice would be appreciated!
Fiddle: http://jsfiddle.net/MeltingDog/S8CUa/1/
Try this -
$("table tr td").each(function() {
var cell = $(this);
if ($(cell).text().length == 0){
console.log('empty');
$(this).parent().addClass('nodisplay');
}
});
Demo
you should try this.
jQuery(document).ready(function(e) {
jQuery(jQuery('table tr td:empty').parents('tr')).addClass('nodisplay');
});
.html() only returns the content of the first matched element, so if your rows have more than one cell this wouldn't work. .text() might be a better fix, unless you have images or other empty tags in the cells.
$("table tr").each(function() {
var cell = $.trim($(this).find('td').text());
if (cell.length == 0){
console.log('empty');
$(this).addClass('nodisplay');
}
});
DEMO
It seems you want to hide rows that have only whitespace content (but the cells might have other element child nodes). Using plain javascript:
var rows = document.getElementsByTagName('tr');
var i = rows.length;
while (i--) {
if ( !trim(getText(rows[i])) ) {
rows[i].className += ' nodisplay';
}
}
Helpers:
function trim(s) {
return s.replace(/(^\s*)|(\s*$)/g, '');
}
function getText(el) {
if (typeof el.textContent == 'string') {
return el.textContent;
} else if (typeof el.innerText == 'string') {
return el.innerText;
}
}
$('table tr').each(function(){
var hide = true;
$('td',this).each(function(){
if ($.trim($(this).text()) != "")
hide = false;
});
if(hide)
$(this).closest('tr').hide();
// OR $(this).closest('tr).addClass('nodisplay');
});
Hide table, if table have no rows using jquery
$('.tblClass').each(function(){
if($(this).find('.rows').length == 0){
$(this).hide();
}
});
