Select text in input field

I am going in circles here. Thought I could fix this issue asked a question earlier answered it only to get stuck again. Have a simple form with multiple panels containing text and numeric input field. When a user clicks in tabs in or whatever the content of that input field text should be selected. I've started looking at THIS article and also looking at the jquery focus and select. Nothing seems to be working. When clicking in the input field nothing seems to be highlighting the text already there.
Thanks
Here are a few things I've tried :
$("input[type=text]").focus(function() {
$(this).select();
});
$('#itemPanel :input[type="text"]').each(function() {
$(this).click(function() {
console.log("I was clicked in");
});
});

How about using on focus
$('input[type=text]').on('focus', function() {
$(this).select();
});
You can also use mouseup
$('input[type=text]').on('mouseup', function() {
$(this).select();
});
Fiddle

To autoselect the text in the input box I would recommend using clickevent instead of the focus event in your example.
This also seems to be written in the code example link you posted. http://www.electrictoolbox.com/jquery-select-function/ (Notice how it's using click instead of focus)
Try this:
$("input[type=text]").click(function() {
$(this).select();
});
--EDIT
Based on some feedback in the comments, there's a link to another similar question that suggests something like this:
$('input[type=text]').focus(function() {
$('input[type=text]').select().one('mouseup', function(e) {
e.preventDefault();
});
});

Fire event with right mouse click and Paste

I want to fire an event in a textarea immediately after paste some text inside the textarea. I can do that when Shift+Ins is used; however, I cannot do it when right mouse button and then paste (from the drop down menu) is chosen. Keyup fires after Shift+Ins. None of the rest fires when Paste is chosen after right mouse button clicking... What do I have to do?
<textarea name="message" id="message"></textarea>
$("#message").on('keyup contextmenu', function(event) {
alert("ok");
});

Thank you

Most browsers support the input event, which is fired when something is pasted or otherwise added, regardless of how:
$("#message").on('keyup contextmenu input', function(event) {
alert("ok");
});
Updated Fiddle
Note that using input is the most general method, firing when the control gets input regardless of how, and so if you hook multiple events (as above), you'll get multiple calls for the same input. For instance, if you hook both keyup and input, on browsers that support input, you'll get two calls. Similarly for paste and input when the user pastes, on browsers that support both.
If you need to support browsers that don't have either input or paste, I'm afraid the unfortunate answer is that you need to poll. Still, polling every (say) 250ms isn't asking the browser to do that much work, and you can feature-detect whether it's necessary:
var message = $("#message");
var events = null;
var previous;
if ('oninput' in message[0]) {
// Browser supports input event
events = "input";
} else if ('onpaste' in message[0]) {
// Browser supports paste event
events = "paste keyup contextmenu";
}
if (!events) {
// Ugh, poll and fire our own
events = "pseudoinput";
previous = message.val();
setInterval(function() {
var current = message.val();
if (current != previous) {
previous = current;
message.trigger(events);
}
}, 250);
}
console.log("Using: " + events);
message.on(events, function(e) {
console.log("Got event: " + e.type);
});
Updated Fiddle

You should use input event callback. See the demo here

You can use the dedicated paste event:
$("#message").on('paste', function(event) {
alert("ok");
});
Updated jsFiddle
However you might want to check browser support - I don't think jQuery normalizes this event.
If you need IE support, it might be a little more difficult, but it depends on your requirements - does it absolutely need to be a paste action? If not, TJ Crowder's answer is the way to go.

The on input is useful if you want to detect when the contents of a textarea, input:text, input:password or input:search element have changed, because the onchange event on these elements fires when the element loses focus, not immediately after the modification.The oninput event is supported in Internet Explorer from version 9.
$("#message").on('input propertychange', function() {
console.log($(this).val());
});

fire jquery focus out when only the input focus is changed

I use the following code to add the selected div value into a input.
var lastFocus;
$('.num-button').click(function(e){
e.preventDefault();
e.stopPropagation();
//addOrRemoveWatermark(lastFocus);
$(lastFocus).val($(lastFocus).val() + $(this).children('span').html());
});
$('.del').click(function(e){
e.preventDefault();
e.stopPropagation();
//addOrRemoveWatermark(lastFocus);
$(lastFocus).val(function(index, text){
return text.replace(/(\s+)?.$/, '');
});
})
below is a sample image if the input panel I have! This is developed for a touch device and hence the key pad.
The script works fine to add value on each button press in the keypad. The problem I'm facing is for the room number I want to run an ajax call after the user has entered the amount. But since the focus is removed every button click, how can I run the script when the focus is changed to another input. I tried the jquery .focusout() method but it gets fired each and every time the user clicks on a number button.
if anyone can suggest me a work around that would be a great help!
thank you!

Perhaps you could delay the request with something like the following:
var roomNoChanged = false;
$('#room-number').change(function() {
roomNoChanged = true;
});
$('#table-number, #no-of-guests').focus(function() {
if(roomNoChanged) {
roomNoChanged = false;
$.post(...)
}
});

Jquery : how to trigger an event when the user clear a textbox

i have a function that currently working on .keypress event when the user right something in the textbox it do some code, but i want the same event to be triggered also when the user clear the textbox .change doesn't help since it fires after the user change the focus to something else
Thanks

The keyup event will detect if the user has cleared the box as well (i.e. backspace raises the event but backspace does not raise the keypress event in IE)
$("#inputname").keyup(function() {
if (!this.value) {
alert('The box is empty');
}
});
jsFiddle
As Josh says, this gets fired for every character code that is pressed in the input. This is mostly just showing that you need to use the keyup event to trigger backspace, rather than the keypress event you are currently using.

The solution by Jonathon Bolster does not cover all cases. I adapted it to also cover modifications by cutting and pasting:
$("#inputname").on('change keyup copy paste cut', function() {
//!this.value ...
});
see http://jsfiddle.net/gonfidentschal/XxLq2/
Unfortunately it's not possible to catch the cases where the field's value is set using javascript. If you set the value yourself it's not an issue because you know when you do it... but when you're using a library such as AngularJS that updates the view when the state changes then it can be a bit more work. Or you have to use a timer to check the value.
Also see the answer for Detecting input change in jQuery? which suggests the 'input' event understood by modern browsers. So just:
$("#inputname").on('input', function() {
//!this.value ...
});

Another way that does this in a concise manner is listening for "input" event on textarea/input-type:text fields
/**
* Listens on textarea input.
* Considers: undo, cut, paste, backspc, keyboard input, etc
*/
$("#myContainer").on("input", "textarea", function() {
if (!this.value) {
}
});

You can check the value of the input field inside the on input' function() and combine it with an if/else statement and it will work very well as in the code below :
$( "#myinputid" ).on('input', function() {
if($(this).val() != "") {
//Do action here like in this example am hiding the previous table row
$(this).closest("tr").prev("tr").hide(); //hides previous row
}else{
$(this).closest("tr").prev("tr").show(); //shows previous row
}
});

Inside your .keypress or .keyup function, check to see if the value of the input is empty. For example:
$("#some-input").keyup(function(){
if($(this).val() == "") {
// input is cleared
}
});
<input type="text" id="some-input" />

What's the event fired when user selects some text on the page?

Either by double click or move the mouse.
Anyone knows about this?

Maybe you can bind a function to document.onmouseup to call document.getSelection()? This is assuming your users use mouse to select the text ;)
document.onmouseup = function() {
var sel = document.getSelection();
if (sel.length > 0) {
alert(sel);
}
}

I think that you refer to the selectevent. See here: http://www.comptechdoc.org/independent/web/cgi/javamanual/javaevents.html

Could it be document.getSelection()?
Here's a web page on that subject.

It's possible to use "onselect", but it works just for form elements (inputs, selects...).
function on_select() {
alert( "selected" );
}
...
<input name="input" onselect="on_select()">

In IE only the select event applies to body text as well as form inputs, so would do what you want. IE and WebKit have selectstart which fires when the users starts selecting, which probably won't help you. To detect when the user has made a selection in a cross-browser way you will need to handle both keyup and mouseup events. Even then you won't be detecting selection events such as the user using the "Select all" menu option (usually found in the Edit and right click context menus). The situation is not ideal in current browsers.
