How to set focus to next input field in a table?
Firstly I worked with that JQuery code: But it only works if the input fields are not spread over different and fields. How could I improve it that code or maybe someone knows a JS code that will work for autofocus fields spread over td and tr fields following tabindex?
<script>
$(document).ready(function(){
$('input').keyup(function(){
if(this.value.length==$(this).attr("maxlength")){
$(this).next().focus();
}
});
});
</script>
My html:
<table>
<tr>
<td><input type="text" id="field1" tabindex="1" name="test1" maxlength = "1"></td>
<td><input type="text" id="field2" tabindex="2" name="test2" maxlength = "1">.</td>
</tr>
<tr><td><input type="text" id="field3" tabindex="3" name="test3" maxlength = "1"></td></tr>
</table>
To do what you require you can retrieve all input elements and get the index of the current one within that collection. To move to the next input, select it from the collection using eq() and the next incremental index value.
Also note that your HTML is invalid - you seem to be missing a <tr> around the final td. I've corrected that in the following example:
jQuery($ => {
let $inputs = $('input').on('input', e => {
let $input = $(e.target);
let index = $inputs.index($input);
if ($input.val().length === $input.prop('maxlength')) {
$inputs.eq(index + 1).focus();
}
});
});

<table>
<tr>
<td><input type="text" id="field1" tabindex="1" name="test1" maxlength="1"></td>
<td><input type="text" id="field2" tabindex="2" name="test2" maxlength="1">.</td>
</tr>
<tr>
<td><input type="text" id="field3" tabindex="3" name="test3" maxlength="1"></td>
</tr>
</table>
It's pretty gross, but would work lol
$(document).ready(function(){
$('table input').keyup(function(){
if(this.value.length==$(this).attr("maxlength")){
tableInputs = $('table').find('input');
$(tableInputs[tableInputs.index(this)+1]).focus();
}
});
});

I am new to mvc 5 and javascript/jQuery please help me how can I use this jQuery function in percentage in every input type which is created by loop but their id is same
As you said you need to call a function on your percentage textbox.
Let me tell you one thing assigning a same Id to a element is bad practice but you can have same name.
Recommend you to use common class attribute or common name attribute
<input type="text" name="percentage1" id="percentage1" class="percentage">
That you can consider as a empty class which will help you for your script operations
eg:
<html>
<head>
<script>
$('.percentage').keypress(function(){
alert('I called');
});
</script>
</head>
<BODY>
<input type="text" name="percentage1" id="percentage1" class="percentage" />
<input type="text" name="percentage2" id="percentage2" class="percentage"/>
<input type="text" name="percentage3" id="percentage3" class="percentage"/>
</BODY>
</HTML>
In the above code I have three textbox where it is pointed to same function which will show alert box.
In your case just apply the emp[#i] to the Id also and have a common class name or have a common name attribute which will help you.
Happy coding.
I want to add and remove textbox in table.
I did add textbox in table.
Am confused to remove textbox in table.
This is my code:
$(function () {
$('.more').on('click', function () {
var $table = $('#input_fields');
var $tr = $table.find('tr').eq(0).clone();
$tr.appendTo($table).find('input').val('');
});
});
$(function () {
$('.delete').on('click', function () {
});
});
.delete{color:#ff0000;}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<form id="quick_post" method="post">
<table id="input_fields">
<tr>
<td><input class="orderinput" type="text" name="product[]" /></td>
<td><input class="orderquan" type="text" name="quantity[]" size="1" maxlength="3" /></td>
<td> <span class='delete'>Delete</span></td>
</tr>
</table>
</form>
<input class="more" type="button" value="Addmore" name="addmore" />
This is my sample code link: https://jsfiddle.net/vo9j2LcL/
Please help me to remove function
Use event delegation to listen the click event on a dynamically generated element.
$(function() {
// cache the table reference
var $table = $('#input_fields');
// keep a cloned copy to generate new
var $tr = $table.find('tr').eq(0).clone();
$('.more').on('click', function() {
// clone to generate new and then append
$tr.clone().appendTo($table).find('input').val('');
});
// set click event handler
$table.on('click', '.delete', function() {
// check number of tr
if ($('#input_fields').find('tr').length > 1) {
// remove the tr corresponds to clicked element
$(this).closest('tr').remove();
}
});
});
.delete {
color: #ff0000;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<form id="quick_post" method="post">
<table id="input_fields">
<tr>
<td><input class="orderinput" type="text" name="product[]" /></td>

I have javascript code to disable other inputs if one is filled .
I need it in table that comes out of database.
The sad thing is that it only works with first table row and disable all inputs in table (but if input filled is not first nothing happens)
Javascript:
$(function(){
$("input").on("keyup", function(){
if($(this).hasClass("inputA") && $(".inputA").val()){
$("input.inputB").prop("disabled", true);
$("input.inputA").prop("disabled", false);
$("input.inputC").prop("disabled", true);
} else if($(this).hasClass("inputB") && $(".inputB").val()){
$("input.inputA").prop("disabled", true);
$("input.inputB").prop("disabled", false);
$("input.inputC").prop("disabled", true);
} else if($(this).hasClass("inputC") && $(".inputC").val()){
$("input.inputA").prop("disabled", true);
$("input.inputB").prop("disabled", true);
$("input.inputC").prop("disabled", false);
} else {
$(".inputA, .inputB").prop("disabled", false);
}
});
});
My td from html table:
<td><input type="text" class="inputA" value=""></td>
<td><input type="text" class="inputB" value=""></td>
<td><input type="text" class="inputC" value=""></td>
How to make it work for each line separated?
Use the same class on each input, create event on those input after that check the value of the input if she's not empty disable all of others input for this works in a line just select all input of the parent.
Try to avoid multiple test as you did. Not lisible and maintainable.
Example
$(".input").on("keypress change keyup",function(){
if($(this).val() != "")
{
$(this).parent().parent().find(".input").not($(this)).prop("disabled",true);
}
else
{
$(this).parent().parent().find(".input").prop("disabled",false);
}
});
.input:disabled{
background-color:LightBlue;
border:solid 1px blue;
}

This solves your issue! Disable all input fields that doesn't have same class as the one being currently edited.
Demo: https://jsfiddle.net/3tf8ou3y/1/
jQuery(document).ready(function($) {
$("tr").on("keyup", "input", function(event) {
// get the current row
var $row = $(event.delegateTarget);
// get the class of the input field being edited
var this_class = $(this).attr('class');
if ($(this).val().length > 0) {
// if the input field has a value, disable all
// other input fields in the sam row
$('input:not(.'+this_class+')', $row).prop('disabled', true);
} else {
// else enable all input fields
$('input', $row).prop('disabled', false);
}
});
});
You can use 'jQuery(this).val()' instead of 'jQuery(".inputA").val()' or 'jQuery(".inputB").val()' or jQuery(".inputC").val()

I have a dynamic row adding table that could add row into the table.
I am showing it in 3 rows, it could be 1 row, or 4 rows, or n rows if a use wants to add data in.
My question is: How can I send data (coil_id) out without click submit button?
In this example, I want to send a coil_id (coil_id = ”coil_22” in this case) to the server without using submit button.
This is also something like: detect if user enter a coil in length of 7 char or digit (Ex: coil_22 or 2C12345), then it will submit the “coil_22” (not coilL_11 or coil_33) to server without click any submit / send button.
I have used JavaScript / jQuery a while, still feel lost sometimes.
Highly appreciate your help.
You can make it with a .keyup(), just add a class to each input for example
<input type="text" class="coil_input" maxlength="7" size="7" name="coil_id" value="coil_11">
<input type="text" class="coil_input" maxlength="7" size="7" name="coil_id" value="coil_22">
<script>
$('.coil_input').keydown(function() {
if($.trim($(this).val()).length == 7){
var now_input_value = $(this).val();
$.post('file.php', {now_input: now_input_value}, function(){ alert('Data sent'); }).fail(function(){ alert('An error has ocurred'); });
}
});
</script>
All the inputs has to have the same class
Remember to add jQuery to your document.
here is example of jquery ajax. serialize will create generate query string that will be sent to your url.
var datastring = $("#yourForm").serialize();
$.ajax({
type: "POST",
url: "your url",
data: datastring,
dataType: "json",
success: function(data) { alert('all ok');}
});
I need to do a form validation with jQuery. But I'm having a problem in this.
I have a HTML form as below:
<FORM id="formID" method="POST" onsubmit="return checkRequiredFields(this)" action="">
<td><input class="required" type="text" id="input1" value="" /></td>
<td><input class="required" type="text" id="input2" value=""/> </td>
<td><input class="required" type="text" id="input3" value=""/> </td>
<td><input type="text" id="input4" value=""/> </td>
<td><input type="submit" id="save" value="Save" /></td>
</FORM>
The first three input text fields are required fields. I tried writing the script like below:
<script type="text/javascript">
function checkRequiredFields(form){
var no_errors = true;
$(form).find(".required").each(function(){
alert("Inside Loop");
var field = $(this);
if (field.val() == ""){
$("#"+field ).css("color","red");
no_errors = false;
} else {
$("#"+field ).css("color","white");
}
});
return no_errors;
}
</script>
But, the above code is not working as I expected. The alert() is never executed, meaning that the control does not find any element with class "required". So, what is the problem in my code?
$("#"+field ).css("color","red"); is not right. field is an object not a string, but since it's already a jQuery object you can just do this: field.css("color","red");. You'll have to do that for the other .css() call too: $("#"+field ).css("color","white"); => field.css("color","white");
