Is it possible to fill textbox using javascript?
I have this code
<input type="text" id="output">
After using the script, I want to have selected value in textbox. I'm very new to javascript and I tried this
javascript: document.getElementById('output').innerHTML = "100";
However, it doesn't work as I expected. So after using the script I want HTML look like
<input type="text" id="output" value="100">
Is there any way to manage this? Thanks
You can use .value or .setAttribute.
document.getElementById('output').value = "100";
or
document.getElementById('output').setAttribute("value", "100");

Is it possible to display input type ="hidden" value?
I need input type hidden because its my requirement and I want to make my generic and apply loop.
I know its a simple question. And I have been searching a lot. I searched and obviously tried also using css, jquery and javascript to visible but I m not getting any solution to it.
The code I tried is:
input type="hidden" id="old1"
and I applied .hide() and .show() function in jquery
Then I tried using in javascript as below:
document.getElementById("Old1").style.visibility = "visible";
OR
document.getElementById("Old1").style.display = "block";
But none of the solution is helping me.
var value = $('#country').val();
alert(value);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="country" type="hidden" name="country" value="Norway">

I m getting its value.
But I want to placed input type="hidden" on UI which I was not getting .
But you people saved my time.
var value = $('#country').val();
alert(value);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input id="country" type="hidden" name="country" value="Norway">
Simply, how can I do this?
<input type="hidden" value="some javascript value" />
I have a form whereby when a user clicks on Add More, more input fields are added via javascript.
I'm also using javascript-declared values to track and limit the number of fields a user can add.
I need a way for my php code to retrieve these javascript values.
Use append
$('#hidden').val('my Text');
input field should be
<input type="hidden" id="hidden"/>
the question is a bit vague, but i will give it a go
try adding a name as an array and then you can use get or post
<input name="myjavascriptinputs[]" type="hidden" value="some javascript value" />
in your php you will be able to use
foreach($_GET['myjavascriptinputs'] as $ajavascriptinput)
From the button you must be calling a javascript to add these fields dynamically. Simply append the code to that function to hand over these values to the field.
<input id="myinputfield[]" type="hidden" value="" />
<script>
function addOneMore(){
var newField = // code to add one more field
newField.value = newValue;
}
</script>
Will solve your purpose.
I'm using jquery, JS and html with a parse.com backend.I cannot find an exact solution on SO or google to this issue.
I've saved a string variable from a db using
document.getElementById("div_name").innerHTML = name;
I'm able to display it on the html page using
<div id= "div_name"></div>
Now I want to add it to an input box and have the string display as the default value in the box. I thought I could do this using
<input type="text" id="div_name"/>
But this only displays a blank box, no data. What have I missed in my approach please?
As Tilwin Joy pointed out, with pieces from original post, e.g.,
<div id= "div_name"></div>
<input type="text" id="div_name"/>
there may be 2 elements with same id ?
try
html
<div id= "div_name"></div>
<input type="text" class="div_name" value="" />
js (utilizing jquery library)
$(".div_name")
.val($("#div_name").text())
jsfiddle http://jsfiddle.net/guest271314/6L7jK/
If you are using <input>, should be
document.getElementById("div_name").value = name;
I have the following form which is getting pre populated with values on load. I want to have empty input boxes on load using Javascript. However I do not have access to the <body> tag so <body onload="" will not work here. Is there any other way to clear the form fields on load?
<form method="POST" action="">
<input name="username" id="user" value="" /><br />
<input name="pwd" id="pass" value="" />
<input type="submit" value="Go" />
</form>
You can use window.onload instead.
function init() {
// Clear forms here
document.getElementById("user").value = "";
}
window.onload = init;
You could also use one of the nice wrappers for doing this in JQuery, Dojo, or you favorite Javascript library. In JQuery it would be,
$(document).ready(init)
Try something like:
window.onload = function(){
document.getElementById("user").value = "";
}
Here's an example
You can run a timeout that will clear the field values. like this:
var t=setTimeout(function(){CLEARVALUES},3000)
Maybe you can add a script tag just after the form.
<script type="text/javascript">document.getElementById("user").value = "";</script>
You can also use jQuery to subscribe to both an individual element's ready (or load) event or the document.
onload=()=>{
document.getElementById('user').value='';
}
or
onload=()=>{
document.getElementById('user').setAttribute('value','');
}
I just creating a booking system and I want that the users will choose a date from the calender and it'll show in input text - that I did!
Now I want to block the writing in the input text (just bring to calender writes there when the user choose a date).
How do I do it? I guess JavaScript, but how? I dont know JS very wall..
Thank you very much!
Give your element the readonly attribute, this will disallow users to type anything into it. However, you will still be able to write to add through javascript for example when a date is chosen. Here is an example:
<input type="text" id="txt" readonly="readonly">
JavaScript:
var el = document.getElementById('txt');
el.value = "Testing......";
Working Demo
<input type="text" id="someId" disabled="disabled" />
The disabled property will prevent any user input, but you can still write to it via your javascript calendar method.
For those who wants to prevent typing but not having the disabled style, can try:
<input type="text" onkeypress="return false;"/>
