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.

I've been attempting to grab text input from HTML and trying to output the text back into HTML but for some reason it does not seem to be working. Does putting input within a form alter the interaction with getElementById or is it possible that the second button usage of formaction is interrupting this?
$(document).ready(function(){
$("#submit").on("click",function(){
var test = document.getElementById("searchInput");
$("#text").html(test);
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type ="text" id ="searchInput"><br>
<button id = "submit">Search</button>
<button formaction="https://en.wikipedia.org/wiki/Special:Random" formtarget="_Blank">Random</button>
</form>
<div id = "text">
<h1>test</h1>
</div>
EDIT: I have attempted to change
var test = document.getElementById("searchInput");
to
var test = document.getElementById("searchInput").value;
previously and it is still not working. Is there an interaction that is failing that I am missing? Also I would like to be able to store the input as variable i.e thats why I am purposely putting it into a variable before outputting it.
EDIT2: There wasn't anything particularly wrong about the code other than retrieving the value. I am currently using codepen.io to code and did not load jquery into the pen.
Since you're using jQuery, it will make more sense to use jQuery to obtain the elements' value:
Use this to always replace #text element contents with #searchInput value:
$("#text").html($("#searchInput").val());
Use this to append #searchInput value to #text element:
$("#text").append($("#searchInput").val());
But the whole logic does not make any sense. You are changing an elements' value that it is outside the form you are submitting. Either you should prevent submit button click event from submitting the form, or have the #text element inside the form as an input, textarea or hidden field:
$(document).ready(function(){
$("#submit").on("click",function(e) {
e.preventDefault();
$("#text").html($("#searchInput").val());
})
});
or having the #text element inside the form for submitting:
<form>
<input type="hidden" id="text" name="text">
<input type ="text" id ="searchInput"><br>
<button id = "submit">Search</button>
<button formaction="https://en.wikipedia.org/wiki/Special:Random" formtarget="_Blank">Random</button>
</form>
You Using form element, so once you click the button , the form will be reloaded, if you want to display textbox value to the element , once remove the form element.
<input type ="text" id ="searchInput"><br>
<button id = "submit">Search</button>
<button formaction="https://en.wikipedia.org/wiki/Special:Random" formtarget="_Blank">Random</button>
<div id ="text">
<h1 id="welc"></h1>
</div>
<script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.1.1.min.js" type="text/javascript"></script>
<script>
$(document).ready(function(){
$("#submit").on("click",function(){
var test = $('#searchInput').val();
$("h1").html(test);
});
});
</script>
Just Remove tag, and check it.
You need to find the element's value and then set it as HTML.
$("#text").html(test.value);
I have updated your question mate check this one .
$(document).ready(function(){
$("#submit").on("click",function(){
var test = document.getElementById("searchInput").value;
$("#text").html(test);
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
<input type ="text" id ="searchInput"><br>
<button id = "submit">Search</button>
<button formaction="https://en.wikipedia.org/wiki/Special:Random" formtarget="_Blank">Random</button>
</form>
<div id = "text">
<h1>test</h1>
</div>
I think this will work for you.
<! doctype HTML>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
<body>
<form>
<input type="text" id="searchInput">
<br>
<button type="button" id="submit">Search</button>
<button formaction="https://en.wikipedia.org/wiki/Special:Random" formtarget="_Blank">Random</button>
</form>
<div id="text">
<h1>test</h1>
</div>
</body>
<script>
$(document).ready(function () {
$("#submit").on("click", function () {
$("#text").html($("#searchInput").val());
})
});
</script>
</html>
Edit your JS code please try:
EDIT:
$(document).ready(function(){
$("#submit").on("click",function(){
var test = $("#searchInput").val();
$("#text").html(test);
})
});
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);
});
I want to get value of one textbox and put the same in another textbox.
my code is :
<input type="text" value="Keyword" id="one" />
<input type="text" value="Search" id="two" />
button
jquery:
var input = $("#one");
$('#btn').click(function(){
alert('dgdhjdgj');
var oneValue = $('#one').val();
alert("one value "+ oneValue);
var twoVal = $('#two').val($(input).attr('value'));
alert('two Val' + twoVal);
});
demo is here.
Issue : when I change the value of textbox #one, it does not change the value of #two.
thanks in advance.
$(input).attr('value') gets the value of the value attribute, which is the initial value, not the current value.
You had it right two lines earlier. Use val().
Try this
HTML
<input type="text" placeholder="Keyword" id="one" />
<input type="text" placeholder="Search" id="two" />
button
Script
$('#btn').click(function() {
var oneValue = $('#one').val();
$('#two').val(oneValue)
})
Fiddle
write textarea and check it. JSFIDDLE
$("#add").click(function(){
var thenVal = $("#textarea_first").val();
$("#textarea_second").val(thenVal);
});
if all that you want to change the text of second textbox, as soon as you change the text of first textbox, just use jQuery's change event.
just try this then:
$('#one').on("change",function(){
$('#two').val($(this).val());
});
I have a form with several text fields. I want to change a span tag when I write something in the field. Like this:
Any ideas?
You can use keyup and then replace the span content with the textbox value.
<input id="test" type="text" />
<span id="content"></span>
$("#test").keyup(function() {
$("#content").html($("#test").val());
});
http://jsfiddle.net/
Edit:
You can also use $(this).val() as pXL has suggested.
$("#test").keyup(function() {
var val = $(this).val();
$("#content").html(val);
});
You can simply use jquery for this. For eg
<input type="text" id="mytext"/>
<span id="content"></span>
$(document).ready(function(){
$("#mytext").keyup(function(){
$('#content').html($(this).val());
})
})
I would use $.keyup() and update the html with input value.
Demo: Working Demo
$(document).ready(function()
{
// Regular typing updates.
$("#input").keyup(function()
{
$("#output").html($(this).val());
});
// If pasted with mouse, when blur triggers, update.
$("#input").change(function()
{
$(this).keyup();
});
// Any value loaded with the page.
$("#input").keyup();
});
The lost focus is also an aproach,
html:
<input type="text" id="txa" value="123" />
<span>345</span>
jquery:
$('input[id=txa]').blur(function () {
$(this).next("span").text($(this).val());
});
Glad to help.
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).
