get the input text field value on tooltip

Get the input text field value on tool-tip.for me I am using text-box with autocomplete..when ever i selected in autocomplete it will show in text-box. when i hover it i want tool-tip the value in text-box..how to get that one can anyone can help me
<input type="text" value="something" class="curate">

Use the title attribute and pass the value of the input into the it on the keyup event.
$(document).ready(function(){
$('#testInput').keyup(function(){
$(this).attr('title',$(this).val())
})
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Type Something
<input type="text" title="" value="" id="testInput">

The first, you set the title is the value,
and do the same when you change the value of textbox
function updateTitle(me)
{
me.title=me.value;
}
<input type="text" title="something" value="something" id="one" class="curate" onchange="updateTitle(this)">

I'd suggest:
$('input.curate').on('change', function (){
this.title = this.value;
});

<input type="text" id="one" value="something" class="curate">
<script>
var x=document.getElementById("one");
x.title=x.value;
</script>

You can using on hover to all inputs in you html like that :
$('input[type="text"],input[type="number"],input[type="date"]').hover(function() {
$(this).attr('title', $(this).val()); });

Input Text Box Returns Undefined in Javascript

Here is my HTML:
<form name='cred' class="panel-body2">
<div class="form-group">
<label for='addjidlbl'> Username (JID):</label>
<input type='text' id='addjid' />
</div>
<input type='button' id='add' value='add' />
</form>
Here is the JavaScript:
$('#add').bind('click', function() {
var jid = $('#addjid').value;
alert(jid);
//var jid=document.getElementById('addjid').value;
var jid2 =$('#addjid').get(0).value;
alert(jid2);
// //$('#addjid').get(0).value;
log('jid=>'+jid);
var data = document.getElementById("addjid").value; //$(".panel.panel-default2#addjid").value;
alert(data);
alert("type=>"+ typeof(jid));
addRoster(jid);
});
function addRoster(jid) {
log('addRoster=>' + jid);
}
What I get are two message boxes with "undefined" and third with "type=>undefined". Why can't I get the input text of the addjid text box?
If I change var jid = $('#addjid').get(0).value;, jid is just blank even when the textbox has value. Why?

Change .value to .val() like
$('#addjid').value
should be
$('#addjid').val()

Here you have it working using .val()
add some text to the text box and
click on the add button and the alert will popup
$('#add').on('click', function() {
alert($('#addjid').val());
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form name='cred' class="panel-body2">
<div class="form-group">
<label for='addjidlbl'> Username (JID):</label>
<input type='text' id='addjid' />
</div>
<input type='button' id='add' value='add' />
</form>

If I understand correctly, you want:
$('#addjid').val()

Since you are using id's to get the value you will only have one element with the given id. When you do .get(0) or any index you are typically trying to get the value out of a given array of values. For Ex
<li>first</li> //0
<li>second</li> //1
Here in a structure like this you will do something like
$("li").get(0)
It will give you the first item with in li.
and to get the value you will need to use .val()
So you can use
$('#addjid').val()
Hope this helps you.
Happy Learning :)

How can I get the Text value of input?

How can I get the value of the textbox?
<input class="num1" type="text" val=""><br>
<button class="show">Click</button>
this is my Js code:
var value = $('.num1').text();
$('.Click').click(function(){
$('<'p>').text(value);
});
when I clicked the "click" button I want to show in a paragraph the text that I'd input to the textbox.

Use .val() for form elements to retrieve or set its value. Also, care with typo when you set the paragraph text.
var value = $('.num1').val();
$('.show').on('click', function(){
$('p').text(value);
});

In your code there is an error: if you want to catch the click event you should use the class of the button. Another error in your code is about the single quotes you use to insert value into the <p>. And remember, is $('p'), not $('<p>').
The code should look like that:
$('.show').click(function(){
$('p').text(value);
});
You can use this code:
jQuery
$(function(){
$("form").on("submit", function(event){
event.preventDefault();
var text = $(".num1").val();
$("#outputText").text(text);
})
});
Your HTML should be something like that:
HTML
<form>
<input class="num1" type="text" val="">
<button class="show">Click</button>
</form>
<p id="outputText"></p>
Note that in this case is really important to stop the default event behavior using preventDefault().
If you are not using a form the previous code became something like that:
jQuery
$(function(){
$(".show").on("click", function(event){
var text = $(".num1").val();
$("#outputText").text(text);
})
});
HTML
<input class="num1" type="text" val="">
<button class="show">Click</button>
<p id="outputText">
</p>
The outputText div is a div I've created to show the text.
I've prepared jsfiddle1, jsfiddle2 you can use to see the code in action, I hope it helps ;-)

That would be
var value = $('.num1').val();

Use the val() operator on the input to get the value, and then you could use the following code:
Html:
<input class="num1" type="text">
<button class="show">Click</button>
<p class="output"></p>
Javascript:
$('button').click(function(){
$('.output').html($('.num1').val());
});

use .val() not .text()
$(".show").click(function(){
var value= $(".num1").val();
$(".para").text(value)
});
demo

$('.show').click(function () {
var value = $('.num1').val();
$('p').text(value);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input class="num1" type="text" val=""></input>
<button class="show">Click</button>
<p></p>
There are type mistakes
var value = $('.num1').val(); should be in click method.
Use val() instead of .text() to get the input value.

Get variable input value on button click

not sure if this is even possible, I have a page with mutiple inputs,each input has a button. is there anyway of getting the inputs value on button click, without hardcoding the inputs id?
example
js
$('button').click(function () {
var inputcontent = $('input').prop('id');
console.log(inputcontent);
});
html
<input type="text" id="1">
<button type="button">Go!</button>
<input type="text" id="2">
<button type="button">Go!</button>
<input type="text" id="3">
<button type="button">Go!</button>
<input type="text" id="99">
<button type="button">Go!</button>

$('input').prop('id') returns id of first matched element in selector. To target the input before each button, you need to use .prev() along with $(this).
Try this:
$(this).prev().attr('id');
Working Demo

You already doing it right, just change a little bit in your code. You have to find out the value of the input field, which is placed just before your button on which you will click. So your code should be:
$('button').click(function () {
var inputcontent = $(this).prev().prop('id');
console.log(inputcontent);
});

This'll solve the issue
$('button').click(function () {
var value = $(this).prev().val();
console.log(value);
});

You're not targeting the item that you want the id from, the input just prior to the button. Use prev(0 to do that. In addition, id is really an attribute, not a property, so you should do this -
$('button').click(function () {
var inputID = $(this).prev().attr('id'); // gets the id of the input that precedes the button
console.log(inputID);
});

input text change onclick button value

Actually i want to create a page switcher, all i need for this is an input with type text where will be entered the number of the page, and i have the second input with type button and onclick value:
<input type="text" value="#number of the page#" />
<input type="button" onclick="_go_page_('cf_pages_form_name1','#number of the page#');" />
I cant figure it out how to take this #number of the page# and put it in onclick dynamically using javascript... please smb help!

<input type="text" id="txtPageNumber" value="2" />
<input type="button" id="btn" value="click" onclick="_go_page_('cf_pages_form_name1','#number of the page#');" />
$(document).ready(function(){
$("#btn").click(function(){
var $val = $("#txtPageNumber").val();
alert($val);
_go_page_('cf_pages_form_name1',$val);
});
});
});

Assuming number is the id of the text field.
You can get the value of the text field like this:
$('#number').val();
And pass that is the onclick event

You can use an ID on the page selector input to get the value.
function goToPage(pageNumber) {
// go to pageNumber
}
<input type="text" id="pageSelector" value="#number of the page#" />
<input type="button" onclick="goToPage($('#pageSelector').val())" />
You've tagged this with jQuery so I'm assuming you're using jQuery.

lets your input type is like this
then in jquery try something like this...
$('#pageNo').keyup(function(){
pageNo = $(this).val()
}
then pass this to your button onclick function

i will answer in "very easy to understand" without jquery:
you have to get the value of the first inputfield. this should your function do. but first the inputfield needs an id(f.g. 'number').
code in function:
var pagenumber = document.getElementById('number').value;
then you have to put the number into the url (document.href).
