disable anchor link '<a>' if one of my six checkboxes are not checked

How can I disable a anchor link if one(1) of my six(6) checkbox is not check?
var first_option = $('#pid-1590083, #pid-1590090, #pid-1590091, #pid-1590092, #pid-1590093, #pid-1590094');
$("a").click(function(e) {
if($("first_option").prop("checked") === false) {
e.preventDefault(); return false;
} else {return true;};
});

Your current logic doesn't work as you're only looking at the checked property of the first element you select, not all of them.
To achieve what you require, you can use the :checked selector to get all the checked elements within the selectors you provide, then check the length property of the result to see if there aren't any. Try this:
var $first_option = $('#pid-1590083, #pid-1590090, #pid-1590091, #pid-1590092, #pid-1590093, #pid-1590094');
$("#tmp_button-99035").click(function(e) {
if ($first_option.filter(':checked').length === 0) {
e.preventDefault();
alert('Please Choose Collar Colour To Continue');
};
});

first_option.prop("checked") will always check for first element. What you have to do is loop over all elements to check
Like this
$("#tmp_button-99035").click(function(e) {
var isChecked = false;
for (var i = 0; i < first_option.length; i++) {
if (first_option.eq(i).prop("checked")) {
isChecked = true;
break;
}
}
if (!isChecked) {
alert('Please Choose Collar Colour To Continue');
e.preventDefault();
}
return isChecked;
});

Well, the js snippet of yours is only checking the first element. So, you have to track other checkboxes as well for correct result.
var first_option = $('#pid-1590083, #pid-1590090, #pid-1590091, #pid-1590092, #pid-1590093, #pid-1590094')
$(document).on('click', '#tmp_button-99035', function (e) {
if ($(first_option).filter(":checked").length == 0) {
e.preventDefault();
}
});

java script query how to filter a table on click

I have a table with five input text for filters as showing in this jsfiddle
https://jsfiddle.net/607y6qdx/2/
I want to filter the information in the table whenever there is a text inside one of these filters and when the users clicks enter.
i already simulated the enter click like this:
$(document).ready(function () {
$('#transactionIDFilter, #messageTypeFilter, #timestampFilter, #messageTextFilter, #originFilter, #destinationFilter ')
.keypress(function (e) {
var key = e.which;
if (key == 13) // the enter key code
{
alert('Oh boy');
return false;
}
});
});
but i couldn't filter the rows.
could you help me please. i am new to js

So the logic you need to follow is
Fetch the value of the input field and get the index of the input
field in which user has pressed enter.
Traverse across all the
Pick td of the index fetched from the firt step.
If the typed value exists in the fetched td then show the entire row or else hide the entired row.
Here is the code which may help:
$(
'#transactionIDFilter, #messageTypeFilter, #timestampFilter, #messageTextFilter, #originFilter, #destinationFilter')
.keypress(function (e) {
var key = e.which;
if (key == 13) // the enter key code
{
$val = $(this).val();
$el = $(this).closest("td");
var index = $("td").index($el);
$("tr").not(".fixed").each(function () {
$elinner = $(this).find("td").eq(index);
if ($elinner.html().indexOf($val) != -1) {
$(this).show();
} else {
$(this).hide();
}
});
return false;
}
});

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);
}
});

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

Delete tagLabel in input-Field with tagit

I use https://github.com/aehlke/tag-it this Addon for Autocomplete Tagging
The user just can take labels out of the existing array sampleTags
Before the tag is added I check whether the element is in Array or not
beforeTagAdded: function(evt, ui) {
var counter = jQuery.inArray(ui.tagLabel, sampleTags);
if (counter != -1 ) { return true; }
else { alert('This word is not in array'); return false; }
},
But the input then is not deleted .
How can I do this?
jsFiddle: http://jsfiddle.net/zqDXL/3/

Try this:
if (counter != -1) {
return true;
} else {
alert('This word is not in array');
$('.tagit-new input').val('');
return false;
}

Cycle Focus to First Form Element from Last Element & Vice Versa

I have created a form with malsup's Form Plugin wherein it submits on change of the inputs. I have set up my jQuery script to index drop down menus and visible inputs, and uses that index to determine whether keydown of tab should move focus to the next element or the first element, and likewise with shift+tab keydown. However, instead of moving focus to the first element from the last element on tab keydown like I would like it to, it moves focus to the second element. How can I change it to cycle focus to the actual first and last elements? Here is a live link to my form: http://www.presspound.org/calculator/ajax/sample.php. Thanks to anyone that tries to help. Here is my script:
$(document).ready(function() {
var options = {
target: '#c_main',
success: setFocus
};
$('#calculator').live('submit', function() {
$(this).ajaxSubmit(options);
return false;
});
$(this).focusin(function(event) {
var shiftDown = false;
$('input, select').each(function (i) {
$(this).data('initial', $(this).val());
});
$('input, select').keyup(function(event) {
if (event.keyCode==16) {
shiftDown = false;
$('#shiftCatch').val(shiftDown);
}
});
$('input, select').keydown(function(event) {
if (event.keyCode==16) {
shiftDown = true;
$('#shiftCatch').val(shiftDown);
}
if (event.keyCode==13) {
$('#captured').val(event.target.id);
} else if (event.keyCode==9 && shiftDown==false) {
return $(event.target).each(function() {
var fields = $(this).parents('form:eq(0),calculator').find('select, input:visible');
var index = fields.index(this);
var nextEl = fields.eq(index+1).attr('id');
var firstEl = fields.eq(0).attr('id');
var focusEl = '#'+firstEl;
if (index>-1 && (index+1)<fields.length) {
$('#captured').val(nextEl);
} else if(index+1>=fields.length) {
if ($(this).val() != $(this).data('initial')) {
$('#captured').val(firstEl);
} else {
event.preventDefault();
$(focusEl).focus();
}
}
return false;
});
} else if (event.keyCode==9 && shiftDown==true) {
return $(event.target).each(function() {
var fields = $(this).parents('form:eq(0),calculator').find('select, input:visible');
var index = fields.index(this);
var prevEl = fields.eq(index-1).attr('id');
var lastEl = fields.eq(fields.length-1).attr('id');
var focusEl = '#'+lastEl;
if (index<fields.length && (index-1)>-1) {
$('#captured').val(prevEl);
} else if (index==0) {
if ($(this).val() != $(this).data('initial')) {
$('#captured').val(lastEl);
} else {
event.preventDefault();
$(focusEl).select();
}
}
return false;
});
}
});
});
});
function setFocus() {
with (document.calculator)
var recap = document.getElementById(recaptured.value);
if (recap!=null) {
setTimeout(function() {
if (recap.getAttribute('type')=='text') {
recap.select();
} else {
recap.focus();
}
}, 100 );
}
}
Edit #1: I made a few minor changes to the code, which has brought me a little closer to my intended functionality of the script. However, I only made one change to the code pertaining to the focus: I tried to to disable the tab keydown when pressed on the last element (and also the shift+tab keydown on the first element) in an attempt to force the focus on the element I want without skipping over it like it has been doing. This is the code I added:
$(this).one('keydown', function (event) {
return !(event.keyCode==9 && shiftDown==true);
});
This kind of works. After the page loads, If the user presses tab on the last element without making a change to its value, the focus will be set to the second element. However, the second time the user presses tab on the last element without making a change to its value, and every subsequent time thereafter, the focus will be set to the first element, just as I would like it to.
Edit #2: I replaced the code in Edit #1, with code utilizing event.preventDefault(), which works better. While if a user does a shift+tab keydown when in the first element, the focus moves to the last element as it should. However, if the user continues to hold down the shift key and presses tab again, focus will be set back to the first element. And if the user continues to hold the shift key down still yet and hits tab, the focus will move back to the last element. The focus will shift back and forth between the first and last element until the user lifts the shift key. This problem does not occur when only pressing tab. Here is the new code snippet:
event.preventDefault();
$(focusEl).focus();

You have a lot of code I didn't get full overview over, so I don't know if I missed some functionality you wanted integrated, but for the tabbing/shift-tabbing through form elements, this should do the work:
var elements = $("#container :input:visible");
var n = elements.length;
elements
.keydown(function(event){
if (event.keyCode == 9) { //if tab
var currentIndex = elements.index(this);
var newIndex = event.shiftKey ? (currentIndex - 1) % n : (currentIndex + 1) % n;
var el = elements.eq(newIndex);
if (el.attr("type") == "text")
elements.eq(newIndex).select();
else
elements.eq(newIndex).focus();
event.preventDefault();
}
});
elements will be the jQuery object containing all the input fields, in my example it's all the input fields inside the div #container
Here's a demo: http://jsfiddle.net/rA3L9/

Here is the solution, which I couldn't have reached it without Simen's help. Thanks again, Simen.
$(document).ready(function() {
var options = {
target: '#c_main',
success: setFocus
};
$('#calculator').live('submit', function() {
$(this).ajaxSubmit(options);
return false;
});
$(this).focusin(function(event) {
$('#calculator :input:visible').each(function (i) {
$(this).data('initial', $(this).val());
});
return $(event.target).each(function() {
$('#c_main :input:visible').live(($.browser.opera ? 'keypress' : 'keydown'), function(event){
var elements = $("#calculator :input:visible");
var n = elements.length;
var currentIndex = elements.index(this);
if (event.keyCode == 13) { //if enter
var focusElement = elements.eq(currentIndex).attr('id');
$('#captured').val(focusElement);
} else if (event.keyCode == 9) { //if tab
var newIndex = event.shiftKey ? (currentIndex - 1) % n : (currentIndex + 1) % n;
var el = elements.eq(newIndex);
var focusElement = el.attr('id');
if ($(this).val() != $(this).data('initial')) {
$('#captured').val(focusElement);
} else if ((currentIndex==0 && event.shiftKey) || (currentIndex==n-1 && !event.shiftKey)) {
event.preventDefault();
if (el.attr('type')=='text') {
$.browser.msie ? "" : $(window).scrollTop(5000);
el.select().delay(800);
} else {
$.browser.msie ? "" : $(window).scrollTop(-5000);
el.focus().delay(800);
}
} else if (el.is('select')) {
event.preventDefault();
if (el.attr('type')=='text') {
el.select();
} else {
el.focus();
}
}
}
});
});
});
});
function setFocus() {
with (document.calculator)
var recap = document.getElementById(recaptured.value);
if (recap!=null) {
setTimeout(function() {
if (recap.getAttribute('type')=='text') {
recap.select();
} else {

}, 1 );
}
}
