I am trying to change text of one div, when I enter different values into my text input:
EXAMPLE:
Input = 1,
DIV TEXT: "rok" //in eng. "year"
Input = 2,
DIV TEXT: "roky"
Input = 3,
DIV TEXT: "roky"
Input = 4,
DIV TEXT: "roky"
Input = 5,
DIV TEXT: "rokov"
Default value of my input is 3.
html
<input type="text" id="pocetrokov" value="3"><span id="year">roky</span>
Js:
function rok() {
if(roky==2 || roky==3 || roky==4){
$('#year').html('roky');
} else if( roky>4 || roky == 0){
$('#year').html('rokov');
} else if (roky==1){
$('#year').html('rok');
}
}
$(function () {
$('select, input').on('keydown blur change', rok);
});
I get this when I change the defalut value:
Input = 1,
DIV TEXT ="rokov" instead of "rok"
Input = 2,
DIV TEXT ="rokov" instead of "rok"
... etc.
I get the correct value only when I click somehere outside the input
What is wrong?
Thank you.
Try this:
function rok(roky) {
if(roky==2 || roky==3 || roky==4){
$('#year').html('roky');
} else if( roky>4 || roky == 0){
$('#year').html('rokov');
} else if (roky==1){
$('#year').html('rok');
}
}
$(function () {
$('input').on('keyup blur change', function(){
rok( $(this).val() );
});
});
Use Keyup Event instead of other,because value of text field is fetched when you keydown and when key down your actual value thats on variable is the previous value,Not the one that is currently in input field So, the function Works correctly :
$(function () {
$('input').on('keyup', rok);
});
Here is DEMO
Guys why are you complicating it so much with 2 functions?
$("html").on("keyup","#pocetrokov",function(){
var roky=parseInt($(this).val());
if(roky==2 || roky==3 || roky==4){ $('#year').html('roky');}
else if(roky>4 || roky === 0) { $('#year').html('rokov');}
else if (roky==1){ $('#year').html('rok'); }
});

I have a textbox which needs to be filled with website URL. So when user places the cursor in the textbox then the textbox should prefill with "http://" (Not a placeholder).
If the user does not enter anything and moves to the next textbox then the textbox have empty value
If the user fills the textbox then the value is unchanged
I tried below Javascript code but did not work:
if (document.activeElement.id == 'input-textbox-id' && !document.activeElement.value) {
document.querySelector("#input-textbox-id").value="http://";
} else if (document.activeElement.id != 'input-textbox-id' && (!document.activeElement.value || document.activeElement.value == 'http://')) {
document.querySelector("#input-textbox-id").value="";
}
You can use the focus and blur events for this.
Assuming that the variable textBox contains the reference to your textBox element, you can use the following code:
let textBox = document.getElementById("a");
textBox.addEventListener("focus", function() {
if (!this.value) {
this.value += "http://";
}
});
textBox.addEventListener("blur", function() {
if (this.value == "http://") {
this.value = "";
}
});
<input type="text" id="a">
You will need to attach event listener by using addEventListener. Events you need: focus and focusout.
We add .http-prefill class for all inputs. We iterate over inputs array and attach event.
Please do not forget to remove eventListener when you are done eg. you unload the form.
To do so, just copy the code for adding listeners and replace addEventListener with removeEventListener.
inputs.forEach(function(input) {
input.removeEventListener('focus', onFocus);
input.removeEventListener('focusout', onFocusOut);
});
Example code:
var fillValue = 'http://';
var onFocus = function() {
this.value = fillValue;
}
var onFocusOut = function() {
if (this.value === fillValue) {
this.value = '';
}
}
var inputs = document.querySelectorAll('.http-prefill');
inputs.forEach(function(input) {
input.addEventListener('focus', onFocus);
input.addEventListener('focusout', onFocusOut);
});
.http-prefill {
width: 100%;
margin-bottom: 5px;
}
<input class="http-prefill" name="input-0" />
<input class="http-prefill" name="input-1" />
<input class="http-prefill" name="input-2" />
<input class="http-prefill" name="input-3" />
you can use some key events like onKeyDown and when keydown you can get hold of old value and append it with new value.
let keyPressed = true
function onKeyDown(event) {
if(keyPressed && event.keyCode !== 8)
{
keyPressed = false;
let oldvalue = document.getElementById('input-textbox-id').value;
document.getElementById('input-textbox-id').value = "http://"+oldvalue
}
if(!document.getElementById('input-textbox-id').value)
{
keyPressed = true;
}
}
here is working code. http://jsbin.com/zoxiwokepi/edit?html,output
I am able to validate all fields within a div but I only want to validate specific fields. Here is a jsfiddle to show what I mean Once validation is passed the div is hidden. I have to enter data in all of the fields so if you check 'Yes' from the checkbox you will see a input field appear I don't want to include that and also if you select 'NoGame' from the dropdownlist once you enter data in all the fields apart from the two fields in the lower div (green border) and click the Test1 button you will see what I mean. Any suggestions?
This is the code which validates all fields and then Hides the div, which can also be seen in the fiddle
function IsValid(divid) {
var $div = $('#' + divid);
var result = true;
$.each($div.find("input[type='text']"), function (i, input) {
if ($(input).val().length == 0 || $.trim($(input).val()) == '') {
result = false;
return;
}
});
return result;
}
$(document).ready(function(){
$("#hide").click(function(){
if (IsValid('contentone')) {
$('#contentone').hide();
};
});
});
Input fields of type text that you don't want to validate exclude them from the validation process
function IsValid(divid) {
var $div = $('#' + divid);
var result = true;
var excludeElement = ["reason"]; //<-- EXCLUDED ELEMENTS IDS
$.each($div.find("input[type='text']"), function (i, input) {
if ($.inArray($(input).attr('id'), excludeElement) < 0 && ($(input).val().length == 0 || $.trim($(input).val()) == '')) {
result = false;
return;
}
});
return result;
}
I have a form with a few input fields, I only want to show a div when all the input fields got content, when one of the input fields has no content the div should disappear again.
I made it work with one input field, but how do I get it to work when all the input fields are filled in (don't know if its a good clean way?):
$(function () {
$('input').change(function() {
$('.next').toggle($(this).val().length !== 0);
}); });
Fiddle:
http://jsfiddle.net/uQyH9/19/
Try this : http://jsfiddle.net/uQyH9/21/
$(function () {
var _cached=$('input');
_cached.change(function() {
if (_cached.filter(function (){return $(this).val().length }).length==_cached.length)
$('.next').show();
else
$('.next').hide();
});
});
You can use a filter function to check that all the input are filled.
Code:
$(function () {
$('input').change(function () {
$('.next').toggle($("input").filter(function () {
return this.value === "";
}).length === 0)
});
});
Demo: http://jsfiddle.net/IrvinDominin/DwF2P/
UPDATE
You can check the value of the elements by type by cheking type attribute.
Code:
$(function () {
$('input').change(function () {
$('.next').toggle($("input").filter(function () {
var myType=$(this).attr("type");
if (myType === "checkbox") return !$(this).is(":checked");
if (myType==="radio"){
var myName = $(this).attr("name");
if (myName==="") return !$(this).is(":checked");
return $('input[name='+ myName +']:checked').length===0
}
return this.value === "";
}).length === 0)
});
});
Demo: http://jsfiddle.net/IrvinDominin/pqJhg/
Loop over the inputs. If you find one that isn't filled in, then hide the DIV. If you don't, show the DIV.
$('input').change(function() {
var allFilled = true;
$('input').each(function() {
if (this.value === '') {
allFilled = false;
return false; // Terminate the loop
}
}
$('.next').toggle(allFilled);
});
What i'm trying to do here is if the selection is equal to value 10 the click function to be available only if selection is equal to 10. But when i change to other ex. category with different value the radio click function is still available. ?
I have 6 radio boxes with value 1,2,3,4,5,6 so what i want to do if value == 4 to slidedown another div while i'm in category with value 10.(selection).
How can i fix this problem ? Here is my sample code.
$('#category').on('change', function () {
var selection = $(this).val();
$('#slidedown'+selection).slideDown(200);
if(selection == '10'){
$("input:radio[name='checkbox']").click(function() {
var radio = $(this).val();
if(radio == '4' && selection == '10') {
$('#slidedown'+selection).slideUp();
} else {
$('#slidedown'+selection).slideDown();
}
});
});
Thanks, any help will be appreciated.
EDIT : I want to slideUp the currect div which is slided down by the category value if radio box with value 4 is checked.
You should have another selection var inside the click callback:
$('#category').on('change', function () {
var selection = $(this).val();
$('#slidedown'+selection).slideDown(200);
});
$("input:radio[name='checkbox']").click(function() {
var selection = $('#category').val(); //This does the trick
var radio = $(this).val();
if(radio == '4' && selection == '10') {
$('#slidedown_another').slideUp();
} else {
$('#slidedown_another').slideDown();
}
});
Also, callbacks must be separated for not binding a new listener each time
Hope this helps. Cheers
Use the disabled property to enable and disable the radio buttons.
$('#category').change(function() {
var selection = $(this).val();
$('#slidedown'+selection).slideDown(200);
$('input:radio[name=checkbox]').prop('disabled', selection != '10');
});
$("input:radio[name='checkbox']").click(function() {
var radio = $(this).val();
if(radio == '4') {
$('#slidedown_another').slideUp();
} else {
$('#slidedown_another').slideDown();
}
});
Your code is adding a handler when the select has the correct value, but it never removes the handler when the select changes to a different value. Also, every time they select 10 it was adding another handler, so the handler would then run multiple times.
For a normal input field i can write something like the below code, which will remove the default value of an input field when i click, and if i dont write anything in the input field, than the default value will return when i leave the input field.
jQuery('input[type="text"]').focus(function()
{
if (this.value == this.defaultValue)
{
this.value = '';
}
if(this.value != this.defaultValue)
{
this.select();
}
});
jQuery('input[type="text"]').blur(function()
{
if (this.value == '')
{
this.value = this.defaultValue;
}
});
But i have no clue how to do this with CKEditor.. Can I get some help.
I found this code which will alert when I click in the CKEditor. But I dont know how modify it to work the way I need.
CKEDITOR.instances['post_content'].on('focus', function()
{
alert(1);
});
Have you tried this?
CKEDITOR.instances['post_content'].on('focus', function()
{
if (this.value == defaultValue)
{
this.value = '';
}
});
Combining the idea above with [this other SO article][1]:
// delete default text on focus
CKEDITOR.instances['editor1'].on('focus', function () {
var defaultText = '<p class=\"ckNormal\">Type your comment here</p>';
var currentText = CKEDITOR.instances.editor1.getData();
// debug - removed
// alert(defaultText + '\n' + currentText);
if (defaultText.trim()==currentText.trim()) {
CKEDITOR.instances.editor1.setData('');
}
});
You probably won't need to trim the text before testing. This uses getData to find what the text is, and setData to change it.
