I currently have a selection of buttons and on click of a button I want to add the text from the button into a text-box. Every time I click on the button I want to be able to append on to whatever I have in the input field.
What I currently have
$('#js-AddFilterOpenBracket').click(function () {
$('#js-FilterString').val($(this).text());
});
What I'm Aiming for
$('#js-AddFilterOpenBracket').click(function () {
$(this).text().appendTo($('#js-FilterString'));
});
No need to use appendTo as it should be used for elements. Rather, manually append to the current value then set it
$('#js-AddFilterOpenBracket').click(function () {
var currentVal = $('#js-FilterString').val();
var newVal = currentVal + $(this).text();
$('#js-FilterString').val(newVal);
});
May not be the bast way but you could do this
$('#js-AddFilterOpenBracket').click(function () {
$('#js-FilterString').val($('#js-FilterString').val() + $(this).text());
});

I have an input field in my code: <input type=text name=code id=code>.
What I want to do is to convert a specific text to another one as the user types in the field.
Let me explain more. When the user enters 31546 in the input, I want that text to directly convert to HELLO.
I know this can be done using JavaScript/jQuery, but I can't have any ideas on how to achieve this. How can I?
P.S. If it's easier to work with a textarea, I'm ready to change my input to a textarea.
EDIT: I got a code from this StackOverflow post which detects any changes to an element,
$('.myElements').each(function() {
var elem = $(this);
// Save current value of element
elem.data('oldVal', elem.val());
// Look for changes in the value
elem.bind("propertychange change click keyup input paste", function(event){
// If value has changed...
if (elem.data('oldVal') != elem.val()) {
// Updated stored value
elem.data('oldVal', elem.val());
// Do action
....
}
});
});
but I am not sure how to utilise this for what I want.
Please bear with me as I am yet a fledgling in this domain.
Thank you.
One option is to set up a keyup event for your input and then replace the value as the user types. For example:
$('input').keyup(function () {
var val = $(this).val();
var newVal = val.split('31546').join('HELLO');
if (newVal !== val) {
$(this).val(newVal);
}
});
You can use keyup event as,
$(document).on('keyup', '#code', function() {
$('#code').val(convertedValue($('#takeInput').val()));
})
function convertedValue(val) {
return 'hello';
}
This may help you :--
<input type="text" id="code">
$('#code').bind('change click keyup onpaste', function(ele){
var origVal = ele.target.value;
if(origVal.indexOf("123") !== -1){
ele.target.value = origVal.replace("123","Hello");
}
});
I need to display the value of the selected item as alert when the user clicks on the #btnValue button.
jQuery(function() {
var catg_str = "";
$('#btnValue').click(function() {
alert(catg_str);
}
$( "#catg_list" ).change(function () {
$("#catg_list option:selected").each(function() {
catg_str += $( this ).text();
});
});
});
I need to display the value inside catg_str as alert when user clicks the #btnValue button. The code above works but the value displays as "undefined". Please help
Just alert the .val() of the select element -- it will be the value attribute of the selected option:
alert($("catg_list").val());
I have a website url field that has the value set for returning visitors who have previously filled out the form. If they change the value, then ('keyup blur paste', function() will copy it to a div. If they do not change the value, the ('keyup blur paste', function() does not copy the value to the div
I would like to figure out how to add to this script a function that would also copy the value to the div if they do not change it, because blur only works if they click in the input before they submit the form.
Here is my current script:
$(function () {
$('#Website').on('keyup blur paste', function() {
var self = this;
setTimeout(function() {
var str = $(self).val();
$("#viewer").text(str.replace(/^http\:\/\//, ''));
}, 0)
})
});
If I get you correctly, you want to populate the div on load as well as on keyup/blur/paste? Something like this?
$(function () {
$('#Website').on('keyup blur paste', function() {
var self = this;
setTimeout(function() {
var str = $(self).val();
$("#viewer").text(str.replace(/^http\:\/\//, ''));
}, 0)
});
// just add the line below
$("#viewer").text($('#Website').val().replace(/^http\:\/\//, ''));
});
I've updated the fiddle you created to demonstrate this working: http://jsfiddle.net/8kn4V/2/
on your page load...
$('#mydiv').html('whatever the value of the cookie');
is that what you need? as they mentioned in the comments above, your question is a little confusing.
use val() for input , select and textareas, and use text() for general elements like divs.
First solution
It seems now you are using a timeout of 0. That is not necessary at all, I think. So please check out this Fiddle:
$('#website').on("keyup blur paste", function () {
var s = $(this).text();
$("#viewer").text(s.replace(/^http\:\/\//, ''));
});
Edited solution
Now it seems you also want code that update #viewer from #website even when not triggered.
Here is a second fiddle — I hope you'll give credit if this solves the problem as it stands currently.
Relevant code:
function viewerupdate(me){
var s = me.text();
$("#viewer").text(s.replace(/^http\:\/\//, ''));
}
$('#website').on("keyup blur paste", function () { viewerupdate($(this)) });
var current_viewer = $('#viewer').text();
$('#submit').click(function(){ // assumes in the case that no change was made, that the submission is done through #submit
if($('#viewer').text() == current_viewer )
viewerupdate($('#website'));
});
I've got the following code in my web page, where I need to click on the input field and add values using the number pad provided! I use a script to clear the default values from the input when the focus comes to it, but I'm unable to add the values by clicking on the number pad since when I click on an element the focus comes from the input to the clicked number element. How can I resolve this issue. I tried the following code, but it doesn't show the number in the input.
var lastFocus;
$("#test").click(function(e) {
// do whatever you want here
e.preventDefault();
e.stopPropagation();
$("#results").append(e.html());
if (lastFocus) {
$("#results").append("setting focus back<br>");
setTimeout(function() {lastFocus.focus()}, 1);
}
return(false);
});
$("textarea").blur(function() {
lastFocus = this;
$("#results").append("textarea lost focus<br>");
});
Thank you.
The first thing I notice is your selector for the number buttons is wrong
$('num-button').click(function(e){
Your buttons have a class of num-button so you need a dot before the class name in the selector:
$('.num-button').click(function(e){
Secondly, your fiddle was never setting lastFocus so be sure to add this:
$('input').focus(function() {
lastFocus = this;
...
Thirdly, you add/remove the watermark when entering the field, but ot when trying to add numbers to it (that would result in "Watermark-text123" if you clicked 1, then 2 then 3).
So, encalpsulate your functionality in a function:
function addOrRemoveWatermark(elem)
{
if($(elem).val() == $(elem).data('default_val') || !$(elem).data('default_val')) {
$(elem).data('default_val', $(elem).val());
$(elem).val('');
}
}
And call that both when entering the cell, and when clicking the numbers:
$('input').focus(function() {
lastFocus = this;
addOrRemoveWatermark(this);
});
and:
$('.num-button').click(function(e){
e.preventDefault();
e.stopPropagation();
addOrRemoveWatermark(lastFocus);
$(lastFocus).val($(lastFocus).val() + $(this).children('span').html());
});
You'll see another change above - you dont want to use append when appends an element, you want to just concatenate the string with the value of the button clicked.
Here's a working branch of your code: http://jsfiddle.net/Zrhze/
This should work:
var default_val = '';
$('input').focus(function() {
lastFocus = $(this);
if($(this).val() == $(this).data('default_val') || !$(this).data('default_val')) {
$(this).data('default_val', $(this).val());
$(this).val('');
}
});
$('input').blur(function() {
if ($(this).val() == '') $(this).val($(this).data('default_val'));
});
var lastFocus;
$('.num-button').click(function(e){
e.preventDefault();
e.stopPropagation();
var text = $(e.target).text();
if (!isNaN(parseInt(text))) {
lastFocus.val(lastFocus.val() + text);
}
});
Live demo
Add the following function:
$('.num-button').live( 'click', 'span', function() {
$currObj.focus();
$currObj.val( $currObj.val() + $(this).text().trim() );
});
Also, add the following variable to global scope:
$currObj = '';
Here is the working link: http://jsfiddle.net/pN3eT/7/
EDIT
Based on comment, you wouldn't be needing the var lastFocus and subsequent code.
The updated fiddle lies here http://jsfiddle.net/pN3eT/28/
I know that there is the change event handling in jQuery associated with an input of type select. But I want to know if the user has selected another value in the select element ! So I don't want to run code when the user select a new element in the select but I want to know if the user has selected a different value !
In fact there are two select elements in my form and I want to launch an ajax only when the two select elements has been changed. So how to know that the two elements has been changed ?
You can specifically listen for a change event on your chosen element by setting up a binding in your Javascript file.
That only solves half your problem though. You want to know when a different element has been selected.
You could do this by creating a tracking variable that updates every time the event is fired.
To start with, give your tracking variable a value that'll never appear in the dropdown.
// Hugely contrived! Don't ship to production!
var trackSelect = "I am extremely unlikely to be present";
Then, you'll need to set up a function to handle the change event.
Something as simple as:-
var checkChange = function() {
// If current value different from last tracked value
if ( trackSelect != $('#yourDD').val() )
{
// Do work associated with an actual change!
}
// Record current value in tracking variable
trackSelect = $('#yourDD').val();
}
Finally, you'll need to wire the event up in document.ready.
$(document).ready(function () {
$('#yourDD').bind('change', function (e) { checkChange() });
});
First of all you may use select event handler (to set values for some flags). This is how it works:
$('#select').change(function () {
alert($(this).val());
});
Demo: http://jsfiddle.net/dXmsD/
Or you may store the original value somewhere and then check it:
$(document).ready(function () {
var val = $('#select').val();
...
// in some event handler
if ($('#select').val() != val) ...
...
});
First you need to store previous value of the selected option, then you should check if new selected value is different than stored value.
Check out the sample!
$(document).ready(function() {
var lastValue, selectedValue;
$('#select').change(function() {
selectedValue = $(this).find(':selected').val();
if(selectedValue == lastValue) {
alert('the value is the same');
}
else {
alert('the value has changed');
lastValue = selectedValue;
}
});
});
You can save the value on page load in some hidden field.
like
$(document).ready(function(){
$('hiddenFieldId').val($('selectBoxId').val());
then on change you can grab the value of select:
});
$('selectBoxId').change(function(){
var valChng = $(this).val();
// now match the value with hidden field
if(valChng == $('hiddenFieldId').val()){
}
});
$("select").change(function () {
var str = "";
$("select option:selected").each(function () {
str += $(this).text() + " ";
});
$("div").text(str);
})
.change();
