How to unhide table rows with autocomplete

How to unhide table rows with autocomplete - javascript

I have an input and table like this :
<td valign="top" style = "padding: 12px 0px 0px 30px;" >
<div class="form-group">
<label for="inputlg">Enter your favorite fruit :</label>
<input class="form-control input-lg" id="inputlg" type="text">
<table style="display: none;">
<tr>
<td> apple </td>
</tr>
<tr>
<td> mango </td>
</tr>
<tr>
<td> carrot </td>
</tr>
</table>
</div>
</td>
I want to unhide "apple" link when the user types "app" on input and unhide "mango" link when user types "man" and so on.. I have googled this problem but I couldn't find anything satisfying. What kind of JavaScript code do I need to achieve this? Thanks.

You could do something like this:
Start by mapping each row of the table in an object (where the key is the text content of the row and the value is the row itself) so that you can quickly access it later. Then add an event listener to the input and when the user types something in go through the object seeing if any of its properties match the value, using the object to show/hide the elements.
let element, elements, i, input, n, tableBody;
elements = {};
tableBody = document.getElementById(`table-body`);
for (i = tableBody.children.length - 1; i > -1; i--) {
element = tableBody.children[i];
elements[element.textContent.trim()] = element;
}
input = document.getElementById(`inputlg`);
input.addEventListener(`input`, filterElements);
function filterElements() {
let key, value;
value = input.value;
for (key in elements) {
if (key.match(value)) {
elements[key].classList.add(`show`);
} else {
elements[key].classList.remove(`show`);
}
}
}
#table-body >* {
display: none;
}
.show {
display: block !important;
}
<td valign="top" style = "padding: 12px 0px 0px 30px;" >
<div class="form-group">
<label for="inputlg">Enter your favorite fruit :</label>
<input class="form-control input-lg" id="inputlg" type="text">
<table>
<tbody id="table-body">
<tr>
<td>
apple
</td>
</tr>
<tr>
<td>
mango
</td>
</tr>
<tr>
<td>
carrot
</td>
</tr>
</tbody>
</table>
</div>
</td>

You can achieve this by writing little more code as below.
$("#inputlg").keyup(function() {
var value = $(this).val();
console.log(value);
if (value == 'app') {
$('.app').attr('style', 'display:block');
} else {
$('.app').attr('style', 'display:none');
}
if (value == 'mon') {
$('.mon').attr('style', 'display:block');
} else {
$('.mon').attr('style', 'display:none');
}
if (value == 'car') {
$('.car').attr('style', 'display:block');
} else {
$('.car').attr('style', 'display:none');
}
})
Note:- I have just added class in particular anchor tag for your help.
Adding code snippet for same.

Unable to clear the form after submitting

I tried a project which has a form to submit the employee expenses. I got everything working but unable to clear the form (entered details in the text fields) after clicking on submit.
Getting Error: (After entering the details and clicking the submit button)
Uncaught ReferenceError: d is not defined at HTMLInputElement.onclick (index.html:63:42)
Here is my code:
document.getElementById("submit").addEventListener("click", (e) => {

Expected output:
After clicking the submit button, entered form details should get cleared.

Here is a simple method,
click reset button automatically after submit
You could reuse the <input type="reset">
cancel icon to clear form values
https://www.w3schools.com/tags/att_input_type_reset.asp
Also, you can hide reset input using display:none, if it is not necessary in your screen
An alternative method is clear each input value by setting an empty value in it
function formReset () {
document.getElementById("empID").value = '';
document.getElementById("name").innerText = '';
document.getElementById("empname").value = '';
}
Here is a working example
document.getElementById("submit").addEventListener("click", (e) => {
e.preventDefault();
// Form validation
function validate() {
if (document.myForm.empId.value == "") {
alert("Please provide your Employee ID!");
document.myForm.empId.focus();
return false;
}
if (document.myForm.empName.value == "") {
alert("Please provide your Name!");
document.myForm.empName.focus();
return false;
}
if (document.myForm.PaymentMode.value == "") {
alert("Select your Payment Mode!");
document.myForm.PaymentMode.focus();
return false;
}
if (document.myForm.Date.value == "") {
alert("Please provide the Date!");
document.myForm.Date.focus();
return false;
}
if (document.myForm.Bill.value == "") {
alert("Please provide your Bill Amount!");
document.myForm.Bill.focus();
return false;
}
return true;

I have a table with a drop-down column in it. Whenever i change the values of drop-down my corresponding fields get enabled. The problem i am getting is if i change the values of my drop-down of previous row the columns of current row also get enabled.Any help will be appreciated. Thanks.
Edit:I have added 'Add Row' function too in my code.

I have added some changes in your disableField function. Pass parameter(this) disableField(this) in that function on chnage event.
function disableField(elem)
{
var Count = $('#dataTable tr').length;
if (Count == 2){
$(elem).closest('tr').find("input").not('.DeleteButton').prop('disabled', false);
}
else{
$(elem).closest('tr').find("input").prop('disabled', false);
}}

All in all there is to much extraneous code so the following answer has different code yet can be applied to the clunky code provided in question. I recommend that your code be more streamlined like the following demo provided in this answer.
Here's some suggestions:
If you are using multiple form controls (ex. <button>, <input>, <textarea>, <select>, etc), wrap everything into a <form>
If you have multiple tags (aka elements) that the user can click, submit, reset, change, input, etc register the events to the <form>
In order to find the exact form control that was clicked, changed, etc. use the Event.target property to find it or this keyword and the Event.data parameter.
$('form selector').on('event type', Event.data, callback function)
The #id and [name] attributes are unnecessary unless you are using certain Web APIs such as HTMLFormControlsCollection or HTMLFormElement
Never use event attributes (ex onchange="callback()") when using jQuery. Use the proper jQuery method or .on() method.
// jQuery method
$(selector).click(callback)
// .on() method
$(selector).on('click', callback)
Minor details:
The [type] attribute does not apply to the <select> tag.
Use <th> instead of <td> within <thead>
[maxlength] of 500 is ridiculous. Use <textarea> instead of <input>
Details are commented in demo
/*
Register form.io to the 'submit', 'click', and 'change' events
Note the callback function does not have `()` suffixed because it would be
interpreted as: "run function now"
The callback function doesn't run immediately it runs when a registered event is triggered.
*/
$('.io').on('submit click change', eventHandler);
// Define the counter
let counter = 0;
// Always pass the Event Object when defining a callback function
function eventHandler(event) {
// The Event Object has several properties...
// Get the type of event triggered (ie submit, change, or click)
let eType = event.type;
/*
Get the origin element of event
if 'submit' target will be <form>
if 'click' target will be <button>
if 'change' target will be <select>
*/
let eNode = event.target;
// Pass the event type through a switch() function...
switch (eType) {
// if type is 'submit'...
case 'submit':
// Create a deep clone of the first row
let clone = $('.grid tr:first-child').clone(true, true);
// Add clone as the last child of the <tbody>
$('.grid').append(clone);
// On .each() elment with class '.data' found within the clone...
clone.find('.data').each(function(i) {
// disable it
this.disabled = true;
// remove its value
this.value = '';
});
// Increment the counter by 1
counter++;
// Dereference the clone and assign id as row+counter
clone[0].id = `row${counter}`;
/*
Prevent default behavior:
Reset <form>
Send data to a server
*/
event.preventDefault();
// Stop event from bubbling any further up the event chain
event.stopPropagation();
// ...otherwise skip this case and continue onto the next case
break;
// if type is 'click'...
case 'click':
// if the clicked element (ie <button>) has class: '.del'...
if ($(eNode).hasClass('del')) {
// Get the clicked <button>'s ancestor <tr>
let row = $(eNode).closest('tr');
// if that <tr> is NOT the first <tr>...
if (row.index() !== 0) {
// remove the <tr>
row.remove();
}
}
event.stopPropagation();
break;
// if type is 'change'...
case 'change':
// if changed element (ie <select>) class is '.type'...
if ($(eNode).hasClass('type')) {
// Get the changed <select>'s ancestor <tr>
let row = $(eNode).closest('tr');
// if changed <select>'s value is NOT "X" return true otherwise return false
let pick = eNode.value !== "X" ? true : false;
/*
On .each() element with class .data within the <tr>
disable the .data if <select>'s value is "X"
Otherwise enable the .data

How to use a cookie to save the clicked value grab the cookie every time the user opens the page

I have following code to highlight table record with three different colors when user click a checkbox. How can I use a cookie to save the clicked value with grab the cookie every time the user opens the page everytime? I haven't no idea how cookies are used. Answer would be really appreciate

localStorage is easier than cookie I thought . You can set and get by localStorage.setItem or localStorage.getItem and it will remain until you remove them !!!
<script>
var cond = JSON.parse(localStorage.getItem("check"));
for(var i in cond) {
if(cond[i]) {
$("#"+i).attr("checked",true);
$("#"+i).parent().parent().addClass("highlight-"+cond[i]);
}
}
function changeSoma(data, color){
var state;
if(localStorage.getItem("check") == null) {
state = {cb1:0,cb2:0,cb3:0};
} else{
state = JSON.parse(localStorage.getItem("check"));
}
if(data.checked) {
$(data).parent().parent().addClass("highlight-"+color);
state[data.id]= color;
} else {
$(data).parent().parent().removeClass("highlight-"+color);
state[data.id]= 0;
}
localStorage.setItem("check",JSON.stringify(state));
}
</script>

it easier using localStorage but since you're using jQuery then use jQuery cookie plugin

I'm assuming you want the values to be selected still even when the user goes to a different page on your site and then select them again once back in that page.
As stated here, you set the cookies using the document.cookie javascript property.
The property mentioned above, however, is a semicolon separated key-value pair. you'll have to manipulate the string in order to add/edit a value.
Once you've added the value that you want, you can once again read it and then set the rows you want to be selected.
To get the selected value, you could use $(data).val() and put it inside changeSoma(). From there, you could check if it's checked $(data).is(':checked'). If it's checked, add it to document.cookie like document.cookie = "key=value; key2=value2;"

Multiple checkboxes with same id and one needs to be selected - jquery

There are multiple checkboxes with same id, in asp.net repeater control. User can select either email or phone against each record in repeater rows.
In following example; there are two rows, if you select the email icon in first row then it ticks relavent checkbox which is fine but if you tick the email icon on the next row then it will untick the first row checkbox instead of ticking the one next to it.
$(function() {
$("[id*=divchkemail]").click(function() {
$(this).toggleClass("image-email");
if ($('#chkemail').prop('checked')) {
$("#chkemail").prop('checked', false);
} else {
if ($('#chkphone').prop('checked')) {
$("#chkphone").prop('checked', false);
$("#divchkphone").toggleClass("image-phone");
}
$("#chkemail").prop('checked', true);
}
});
$("[id*=divchkphone]").click(function() {
$(this).toggleClass("image-phone");
if ($('#chkphone').prop('checked')) {
$("#chkphone").prop('checked', false);
} else {
if ($('#chkemail').prop('checked')) {
$("#chkemail").prop('checked', false);
$("#divchkemail").toggleClass("image-email");
}
$("#chkphone").prop('checked', true);
}
});
});

JSFiddle
http://jsfiddle.net/g8Xuz/48/

although you must use unique id's for elements, given your scenario I've written down this fiddle.
i've used this $(this).parent().next('td').find('input:checkbox'); to find the checkboxes
please try this http://jsfiddle.net/g8Xuz/50/

This works.
I gave the rows a class of contact. It can also work without the class on the rows by using $("table > tr") instead. No need to know the exact class names and can handle any number of sets allowing the correct unique IDs for the fields.
FIDDLE
$(function () {
$(".contact").on("click", function (e) {
var $div = $(this).find("div"); // the div on the clicked row
var divClass = $div.prop("class"); // its class
var $checkbox = $(this).find("input"); // the checkbox
var check = $checkbox.is(":checked"); // whether or not it is checked
if (e.target.type != "checkbox") { // we clicked somewhere else
check = !check; // toggle
$checkbox.prop("checked", check); // set the check
}
if (check) { // are we enabling?
if (divClass.indexOf("disabled") != -1) { // disabled?
$div.removeClass(divClass).addClass(divClass.replace("-disabled", ""));
}
}
else { // disable it
$div.removeClass(divClass).addClass(divClass + "-disabled");
}
var $otherContact=$(this).siblings("tr"); // the sibling row
if (check) {
$div = $otherContact.find("div");
divClass=$div.prop("class");
if (divClass.indexOf("disabled") == -1) {
$div.removeClass(divClass).addClass(divClass+"-disabled");
}
$checkbox=$otherContact.find("input"); // the checkbox
if ($checkbox.is(":checked")) $checkbox.prop("checked",false);
}
});
});

It's happening because you are selecting element by id and which is duplicate. You have to find your required element traversing up through its ancestors in the DOM tree so that selector only select elements within current row by setting a area of elements. Here is working code.
$(function () {
$("[id*=divchkemail]").click(function (e) {
var currentRow = $(e.target).parents().closest('table');
$(this).toggleClass("image-email");
if ($(currentRow).find('#chkemail').prop('checked')) {
$(currentRow).find('#chkemail').prop('checked', false);
}
else {
var chkPhoneInCurrentRow = $(currentRow).find('#chkphone')
var divchkInCurrentRow = $(currentRow).find('#divchkphone')
if ($(chkPhoneInCurrentRow).prop('checked')) {
$(chkPhoneInCurrentRow).prop('checked', false);
$(divchkInCurrentRow).toggleClass("image-phone");
}
$(currentRow).find('#chkemail').prop('checked', true);
}
});
$("[id*=divchkphone]").click(function (e) {
var currentRow = $(e.target).parents().closest('table');
$(this).toggleClass("image-phone");
if ($(currentRow).find('#chkphone').prop('checked')) {
$(currentRow).find('#chkphone').prop('checked', false);
}
else {
var chkEmailInCurrentRow = $(currentRow).find('#chkemail')
var divchkInCurrentRow = $(currentRow).find('#divchkemail')
if ($(chkEmailInCurrentRow).prop('checked')) {
$(chkEmailInCurrentRow).prop('checked', false);
$(divchkInCurrentRow).toggleClass("image-email");
}
$(currentRow).find('#chkphone').prop('checked', true);
}
});
});

Here is working fiddle.
http://jsfiddle.net/hannnan/noukkjsq/

This is happening because you are using the same IDs for everything - the JS cannot differentiate between the two rows. So you click the second row's icon, the first element it finds with your ID (#divchkemail) it performs the action on, which is in the first row.

How to disable button click if value inputed is less than Minimum bid amount?

I would like to be able to disable button click if the value entered in the text box below named "bidamt" is less then the Minimum Bid value below in the table. How do I go about doing this? I am trying to do this in JavaScript but it doesnt seem to pull the Minimum Bid value. Any help would be greatly appreciated.

With jquery you can try this:
To use jquery you just embed
<script src="http://code.jquery.com/jquery-1.10.2.js"></script>
on the head tag of your html file. And put this on your click event.
$("#Bid").attr('disabled','disabled');
like this:
$("#Bid").click(function(){
if(something true){
$(this).attr('disabled','disabled');
}
});

You put your bidamt textbox in foreach loop and you set id="bidamt". So the problem is you can not set the same id many element, id is unique. The second problem is you called checkBids function on click event of button, so you can not get value of the button.
