How to print the value of a web element in console? - javascript

I have a web element which I have found css selector for and now I want to print its value in console. How to achieve this?

Not sure what exactly you mean by value
In html these tags will have value attribute
<button>, <option>, <input>, <li>, <meter>, <progress>, <param>
For example
<button type="button" value="1" id="myButton">My button</button>
Here you can use a id selector(or any other relevant selector) to get the DOM element
var _getValue = document.getElementById('myButton').value; // will give 1
Now use console.log like console.log(_getValue) which will log the value in console of developer's tool
If your looking for text inside element like span you have to do innerHTML or textContent to get the text
<span id ="myspan"> My Span </span>
var _getValue = document.getElementById('myspan').innerHTML;
console.log(_getValue)

If you fetched the element by:
var x = document.getElementsByClassName("classNameHere"); you'll have an array of HTML elements. Extract the first element:x = x[0]; than get the content by console.log(x.innerHTML());
If your element is an input use console.log(x.value) to get the value.

If you have the following:
<input id="myValue" type="textbox" value="foo bar">
You can log the value like so:
var elem = document.getElementById('myValue');
console.log(elem.value);

Get an attribute name with document.getelementbyid in js

Why is it doesn't work?
var x = document.getElementById('test').name;
alert(x); // jhon
<div id='test' name='jhon'> its just a text </div>
Div elements are not allowed name attributes, so there is no matching property for them on the DOM.
If you want to store custom data on an element, use a data-* attribute.
If you really want to use invalid HTML you can access it with the getAttribute method.
You will have to use getAttribute method to get value of any attribute of html element
var x = document.getElementById('test').getAttribute("name");
console.log(x)
<div id='test' name='jhon'> its just a text </div>
Try this:
var x = document.getElementById('test').getAttribute('name')

How do you move text from a div into an input value?

I am trying to move text from inside a div into the value from an input field but I'm getting [object Object] as the output. Can anyone explain why?
input = $('#input').contents();
$('#output').val(input);
Spencer.
The .contents() method won't give you the text, but an object with a collection of the elements it contains. You sould use:
val method:
The .val() method is primarily used to get the values of form elements
such as input, select and textarea.
text method:
The .text() method cannot be used on form inputs or scripts. To set or
get the text value of input or textarea elements, use the .val()
method.
The line you're looking for is:
$('#input').val($('#div').text());
and can be decomposed like this:
var textToMove = $('#div').text();
$('#input').val(textToMove);
Here is a full example:
function move(){
$('#input').val($('#div').text()); //copy text
$('#div').text(''); //erase text
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id='input' type='text' value=''>
<div id="div">Hello, Spencer</div>
<button onclick='move()'>Click to move text</button>
First get the text content with
$("#d").text()
Add this to input like
$("#y").val($("#d").text());
Now you can remove text of div like
$("#d").text("")
$("#y").val($("#d").text());
$("#d").text("")
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>
<div id="d">text</div>
<input type="text" id="y"/>
Note:
Given a jQuery object that represents a set of DOM elements, the .contents() method allows to search through the immediate children of these elements in the DOM tree and construct a new jQuery object from the matching elements. and the results includes text nodes and comment nodes as well as HTML elements in the resulting jQuery object. Here
That's why you are getting object. you really need to use .text() here to get the text contents only.
The contents() you were trying to use is defined by the jQuery documentation as
To get the children of each element in the set of matched elements,
including text and comment nodes
So, contents() is returning en entire object with all those children, comments and etc... that's why: [Object Object]. If you use console.log($('#input').contents()) you will be able to see the entire object in the console.
So, in that case, it's better to use text(), that get only the text content of the element matched.
After getting the text, then set it to the input with val();
the example below shows this. (I added a timer just to better represent the code working, you can remove it and let only the code that is inside).
Also, if you want to keep the text in the div, remove the part where I used .text('');
setTimeout(function(){
input = $('#input').text();
$('#output').val(input);
$('#input').text('');
}, 1500);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type='text' value='' id="output">
<div id="input">Abcdef 1234567890</div>

How to get value from a dynamic element

I need to get the value from a "p" element, I draw this "p" with jQuery and it's ok, then I have a button and when I click on it I want to display the value from "p" element but I don't get any information, here is a simple code example:
$(document).ready(function() {
$('#c').click(function() {
var p = $('#p1').val();
alert(p);
});
draw();
});
function draw() {
var html = "";
html += '<p id="p1">Hi</p>';
$('#d').html(html);
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button id="c">Click</button>
<hr />
<div id="d">
</div>
How can I solve this? I don't get any console error.
Change :
var p = $('#p1').val();
To :
var p = $('#p1').text();
.val() only returns the value from input, textarea and select elements. If you just want to read the content of an element, you should use .text() or .html(). The first returns just the text, and the second – HTML content of an element.
Here is the quote from jQuery
The .val() method is primarily used to get the values of form elements
such as input, select and textarea. When called on an empty
collection, it returns undefined.
So as #ehsan suggested, use .text() method if you want to get content as text.
.val() is used to get the value of input, select and textarea elements.
If you want to get the text inside an element (e.g: div, p, etc), you need to use .text().
So, in your case, you need to change this:
var p = $('#p1').val();
for this:
var p = $('#p1').text();
Note: If you want the full html code inside an element, you need to use .html().
Sources:
http://api.jquery.com/val/
http://api.jquery.com/text/
http://api.jquery.com/html/
you can also use var p = $('#p1').html();

How to access HTML of a Input element

Hi I am trying to get the HTML of INPUT tag. But unable to..
<input type="checkbox" name="_QS4_CNA" id="_Q0_C7" class="mrMultiple" value="NA">
<label for="_Q0_C7">
<span class="mrMultipleText" style="">None of these</span>
</label>
</input>
And I am trying access as
var dat=$(':checkbox#_Q0_C7').html();
alert(dat);
But i cannot access this. Please help me on this..
The ".html()" method gets the contents of an element, and not the element itself. In your case, the problem is that your HTML is invalid. An <input> tag cannot have content. As far as the browser is concerned, the tag ends where the <label> tag starts, and the browser just ignores the closing tag.
Note that when you've got an "id" attribute to use to find an element, you don't need any other qualifiers in the selector (like ":checkbox"). Just "#_Q0_C7" is all you need, because "id" values have to be unique anyway.
edit — Note that if all you want is to get some attribute (like the value or the "checked" status) from the element, you can certainly do that:
var $cb = $('#_Q0_C7');
var isChecked = !!$cb.prop('checked'); // force a real boolean value
var value = $cb.val();
You can try accessing the RAW underlying DOM element and use its innerHTML property.
var dat = $(":checkbox#_Q0_C7")[0].innerHTML;
But like mentioned by Pointy, that might still get you nothing. Not sure what (if any) input elements have actual siblings.

getting the value of a div in jquery?

i wanted to get the value of a hidden div in jquery i.e.
<div id="text">hello i am the value, you want</div>
and i want insert this value into a another div in jquery i.e.
$('#bio').html($value);
EDIT:
i forgot to mention that it had to be the text within the block div sorry i.e. its parent
<div class="block" id="status_13">
<div id="text">.......</div>
</div>
i.e.
$('.block').click(function(){
$('#bio').html($('$text').html());
If your #text element contains HTML you might want to do:
$('#bio').html($('#text').html());
If you are only concerned with the literal text of #text then you can do:
$('#bio').text($('#text').text());
Of course, if you want to store the text in a variable first, you can do so:
var textValue = $('#text').text();
$('#bio').text(textValue);
In regard to your later edit:
$('.block').bind('click', function() {
var thisTextValue = $(this).children('.text').first().html();
$('#bio').html(thisTextValue);
});
Notice that I assumed the child div is marked with a class and not an id. Based on your description, it sounds like you have multiple "block" elements which each contain a "text" element. If that is the case, then $('#text') will always return the first "text" element in the document; IDs are unique in the document.
Don't use $ for variables (like $value), just value
var value = $('#text').html();
Did you try
$('#bio').html($('#text').html());
I think this would work
//get the value from hidden field and store it in the variable 'valueYouWant'
var valueYouWant = $("#text").html();
//set it in other field
$("#bio").html(valueYouWant);
