I have checked the other same posts and I have done numerous changes but nothing seems to work! My goal is to create a form, in html, that when the user is submitting data having clicked on the plane or ship to redirect him in another form A and for the rest (train, bus) to the form B. For that I have the foo function in javascript. But when I click on submit button the onclick function does not work! Any ideas why?
<HTML>
<HEAD> <title> Ticket Choice </title></HEAD>
<SCRIPT type="text/javascript">
function foo(){
alert("Submit button clicked!");
if (document.getElementById('buttonCheck1') ||
(document.getElementById('buttonCheck2')) {
document.forms['form0'].action="C:/Users/Jo/workspace/myAskisisDir/WebContent/formA.html";
}
else {
document.forms['form0'].action="C:/Users/Jo/workspace/myAskisisDir/WebContent/formB.html";
}
}
</SCRIPT>
<BODY>
<h1> Choice of transfer ticket </h1>
<FORM id = "form0" method = "GET">
<fieldset title = "plane">
<input type = "radio" onclick = "javascript:IsCheck(1);" name = "button" id =
"buttonCheck1"> PLANE <br>
</fieldset>
<fieldset title = "ship">
<input type = "radio" onclick = "javascript:IsCheck(2);" name = "button" id =
"buttonCheck2"> SHIP <br>
</fieldset>
<fieldset title = "train">
<input type = "radio" onclick = "javascript:IsCheck(3);" name = "button" id =
"buttonCheck3">train<br>
</fieldset>
<fieldset title = "bus">
<input type = "radio" onclick = "javascript:IsCheck(4);" name = "button" id =
"buttonCheck4"> bus <br>
</fieldset>
<input type="submit" value="submit" onclick = "foo();"/>
<input type = "reset"/>
</FORM>
</BODY>
</HTML>
syntax error
if (document.getElementById('buttonCheck1')||(document.getElementById('buttonCheck2')) {
should have been
if (document.getElementById('buttonCheck1') || document.getElementById('buttonCheck2')) {
now you can feel stupid :P
Try it, this triggers the onclick function. Cheers!

So, I have a form on my HTML page, and a separate button that links to the form. My question is: when the user enters a certain input (in this case a string) and clicks on the button, how do I connect the user to a different HTML page based on the corresponding user input from the form? I know I have to use javascript, but any specific code will be extremely helpful. Thanks!
ADDDED MY CODE:
<!doctype html>
<html>
<head>
<title>Home</title>
</head>
<body>
<form id = "user-info" onSubmit="myFunction()">
<div class = "favorite-fruit">
<p>Enter your favorite fruit<br></p>
<input type="text" name="fav-fruit" id = "fruit"><br>
</div>
<div class="favorite-vegetable">
<p>Enter your favorite vegetable<br></p>
<input type="text" name="fav-vegetable" id="vegetable">
</div>
</form>
<a class = "confirm" onSubmit="myFunction()">
<button form= "user-info" type="button" name= "confirm-input">Confirm</button>
</a>
</div>
<script type="text/javascript">
function myFunction(){
var firstFruit = document.getElementById("fruit").innerHTML;
var secondVegetable = document.getElementById("vegetable").innerHTML;
var f = firstFruit;
var s = secondVegetable;
if(f.value == "Apple" && s.value == "Broccoli"){
//GO TO "appleBroccoli.html"
}
else if(f.value == "Grapes" && s.value == "Carrots"){
//GO TO "grapesCarrots.html"
}
else if(f.value == "Strawberry" && s.value == "Kale"){
//GO TO "strawberryKale.html"
}
}
</script>
</body>
</html>
It can be done by taking up the value of input tag like :-
var value = $(element).val();
Then resetting the action attribute of the form tag with the new value like :-
$(formElem).attr("action",value+".html")
I guess this would help u..
Your form, user-info doesnt have a submit button
add <input type = 'submit' name='conform'>Confirm</input> inside the form
Set action and method to the form to the corrosponding target HTML page.
<form action='..target html' method ='get'>
</form>
If the input is brocolli, you can change the form action as
document.getElementById('user-info').action = <new target>
I want to verify the inputs by javascrpit function perform() and move to a php page named i.php to save the datas in the databasse.
Here is the code:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<form action="i.php" method="post">
<br>
Name <input type="text" name="name" id="name" >
<span id="err"></span>
</br>
<br>
Password <input type="Password" name="Password" id="password">
<span id="perr"></span>
</br>
<br>
Gender
<input type="radio" name="gender" id="gender" value="male">Male
<input type="radio" name="gender" id="gender" value="female">Female
</br>
<br>
Department <select name="department" id="department">
<option>------</option>
<option>ECE</option>
<option>BBA</option>
<option>ENG</option>
</select>
</br>
<br>
<button name="btn" type="button" id="btn" onclick="perform()" >Button</button>
<input type="submit" name="submit" value="Submit">
<input type="reset" name="reset" value="Clear">
</br>
</form>
<script type="text/javascript">
function perform()
{
var name = document.getElementById('name').value;
var pass = document.getElementById('password').value;
var dept = document.getElementById('department').value;
var gender = document.getElementsByName('gender');
var r =3;
if (name.length==0)
{
document.getElementById('err').innerHTML = "name not found";
r++;
}
if (pass.length<=6 || pass.length>=32 )
{
document.getElementById('perr').innerHTML = "password error";
r++;
}
if(r==3)
{
window.location= "i.php";
}
}
</script>
</body>
</html>*
In i.php page i used var_dump to see the datas whether it has been submitted or not. code of the i.php page:
<!Doctype html>
<html>
<head></head>
<body>
<?php
var_dump($_POST);
?>
</body>
</html>
But its showing arry(0) {}
looks like there nothing that has been submitted.
The issue is that you're redirecting with javascript, and losing the entire form and it's data by doing so.
When the form is valid, submit it rather than redirecting
function perform() {
var _name = document.getElementById('name').value;
var pass = document.getElementById('password').value;
var dept = document.getElementById('department').value;
var gender = document.getElementsByName('gender');
var valid = true;
if (_name.length === 0) {
document.getElementById('err').innerHTML = "name not found";
valid = false;
}
if (pass.length <= 6 || pass.length >= 32) {
document.getElementById('perr').innerHTML = "password error";
valid = false;
}
if (valid) {
document.querySelector('form').submit();
}
}
Note that name is not a good name for variables or form elements, as it already exists in window.name, and that a submit button can not be named submit as it overwrites the named form.submit() function
Another option would be to just remove all the javascript, and use HTML5 validation instead.
Use this code:
<form action="i.php" method="post" onsubmit="perform();">
And in javascript make these changes:
if(r!=3) {
alert('please complete the form';
return false;
}
Javascript doesn't send POST headers with window.location!
By using this code, you don't need to use a button, javascript perform() function runs when the submit button is clicked in the form.
If form values are entered truly, javascript perform() does not return and form submits; else, the function returns and prevents submitting the form.
The problem is you are not submitting the form you are just going to a different page with javascript without passing along any variables. so instead of doing
window.location= "i.php";
you should submit the form like so
document.getElementById("formId").submit();
so you should give the form the id formId
The problem is that you are merely redirecting to the i.php page without posting any data. Replace this line in your JS:
window.location = "i.php";
with this
document.getElementsByTagName('form')[0].submit();
This will find the form in your DOM and submit it along with the data that has been input, preserving the values for your action page.
You also need to rename your submit-button for this to work. Otherwise you will not be able to call the submit function on the form programmatically.
<input type="submit" name="submit-btn" value="Submit" />
should do the trick. However, I don't really see the point of the submit button in addition to your validation/submission button.
Full code sample of the solution here: https://jsfiddle.net/dwu96jqw/1/
by press btn you redirect only and your form dont submitted for transfer via _POST
you should change your code :
<form action="i.php" method="post" id ="form1">
and :
if(r==3)
{
form1.submit();
}
window.location will redirect you to the page, to preserve field values return it
if(r==3)
{
return true;
}
This is the HTML code:
<body>
<form>
<input id="input" type="text" name="input" value="Enter Here">
<input type="submit" value="Submit">
</form>
<div id="display">
</div>
</body>
This is the JavaScript:
input = document.getElementById("input");
if (input.value == "Hello") {
display.innerHTML = "Hello";
} else {
display.innerHTML = "Type";
}
When I change the input value by clicking on the input field and typing "Hello", it does not display "Hello" in display.innerHTML. I would like it to display "Hello" when "Hello" is typed into the input field. That's a lot of "Hello"'s! Any help would be great! Thanks in advance.
var input = document.getElementById("input"),
display=document.getElementById("display");
input.oninput=function(){
if (input.value === "Hello") {
display.innerHTML = "Hello";
} else {
display.innerHTML = "Type";
}
};
<input id="input" type="text" name="input" value="Enter Here">
<div id="display">
</div>
Your javascript code only gets executed once before you have entered anything in the input field.
You need to either setup a change handler for the input field or a submit handler for the form and set display.innerHTML.
Also, did you miss a display = document.getElementById("display");?
If you want use your button for submit the value of your textbox (your input type text-field) use onclick event as follows:
function displayData() {
var div_display = document.getElementById('display');
/* This is your input, but you shoud use another Id for your fields. */
var textValue = document.getElementById('input').value;
/* Change the inner HTML of your div. */
div_display.innerHTML = textValue;
}
<input id="input" type="text" name="input" value="Enter Here" />
<input type="submit" value="Submit" onclick="displayData();" />
<div id="display">
</div>

Whenever the checkbox is checked, the code should automatically copy the values from first field into the second field. If the checkbox is unchecked, the second one should go blank. as per my code the first requirement is ok, but I couldn't make it blank when it is unchecked. Can anyone help plz.
Add document.getElementById("billingName").value = null; to the else clause.
Fiddle
Just set the value to an empty string in the else clause
function billingFunction() {
var shippingName = document.getElementById("shippingName");
var billingName = document.getElementById("billingName");
if(document.getElementById("same").checked ) {
billingName.value = shippingName.value;
} else {
billingName.removeAttribute("required");
billingName.value = "";
}
}
You only need to modify the else block
else{
document.getElementById("billingName").value="";
}
JSFIDDLE
EDIT
You have put the billing function inside header. You must be comming across reference error.
You can put this billing function inside window.onload or pu this script near closing body tag
window.onload= function(){
billingFunction;
}
function billingFunction(){ //Rest of code}
JSFIDDLE with window.onload
I'm trying to change my 'send' button which onClick sends a message from an input box to a div, to also trigger the click of a 'checkbox' input.
HTML
<button type="submit" class="btn btn-default">Post</button>
<input name="stry" type="text" id="stry"/>
<input name="nope" type="text" id="message-input"/>
<input type="checkbox" name="sendsms" onclick="copyStory(this)">
*These buttons are actually in a form
JS
function copyStory(ch) {
if (ch.checked)
var text1 = document.getElementById("message-input").value;
else
text1 = '';
document.getElementById("stry").value = text1;
}
I've searched around but I can't find a way to make the send button trigger the checkbox, any suggestions?
So what you need is to have same handler for both onclick and onchange events. Try this way,
HTML :
<input type="button" id="sendButton" value="Send" onclick="copyStory(this)" />
<input name="nope" type="text" id="message-input"/>
<input type="checkbox" name="sendsms" onchange="copyStory(this)"/>
<div id="msgDiv"></div>
javaScript :
function copyStory(ch) {
var text1
if (ch.checked || ch.id == "sendButton")
text1 = document.getElementById("message-input").value;
else
text1 = document.getElementById("msgDiv").innerText = "";
document.getElementById("msgDiv").innerText = text1;
}
