I currently have a button in HTML with the following code:
<form id="tfnewsearch" method="get" >
<input type="text" id="search_query" name="q" size="21" maxlength="120"><input type="button" id="search_button" name="search" value = "Search"onclick="doSearch(this.form.q)">
</form>
The function 'doSearch()' works only if I click the submit button. What changes do I have to do if it has to work even if I just press the Enter key?
<form id="tfnewsearch" method="get" onsubmit="doSearch()" >
Simply change the onclick to an onsubmit and attach it to your form!
The proper way it to move it to simple JS script
<script type="text/javascript">
var form = document.querySelector('#tfnewsearch'),
query = form.querySelector('[name="q"]');
form.addEventListener('submit', function(){
doSearch(query.value);
});
</script>

Here is my form:
<form id="myForm">
<input id="htmlString" type="text" name="htmlField" ><br>
<input type="Submit" value="Submit" >
</form>
And need to fill it from console.
just to use it in my app,
Will inject javascript with data to local html file.
I tried to make the form without a submit button like so:
<body>
<form id="myForm">
<input id="htmlString" type="text" name="htmlField" ><br>
</form>
<script>
htmlString.oninput = function(){
///do some stuff
}
</script>
</body>
Expecting that :
document.getElementById('htmlString').value="moo" ;
It automatically submit the form, because here oninput used.
But it just stayed filled with inputs and not proceed further.
Tried with other solution:
form = document.getElementById("myForm")
form.submit()
But it just refreshed the page and not submitted the form.
The need is just one filed without else, and inject my string to it with javascript to run functions embedded in the html.
Try making the input button hidden.
<body>
<form id="myForm">
<input id="htmlString" type="text" name="htmlField" ><br>
<input type="Submit" value="Submit" style="display: none" >
</form>
<button onclick="simulateConsole()">Try it</button>
<script>
htmlString.oninput = function(){
if(this.value === "moo") {
myForm.submit();
}
}
// This event will be triggered even if you use console
htmlString.onsubmit = function(){
if(this.value === "moo") {
// do something onSubmit
}
}
function simulateConsole() {
// you can simulate this in console
htmlString.value = "moo";
myForm.submit();
}
</script>
</body>
I hope it helps.
You need to supply an action to the form, otherwise it will just reload the page.

I am having a form like this
<form name="test" action="action.php" method="get">
<input type="text" />
<input type="button" value="download"/></form>
I need a click event for download button. Eg. If i click download it should submit as action.php and run $('#button').click(function(){ also. How can I do it.
Perform the operation on 'download' button click then trigger the form submit using trigger
$('.download').click(function(e){
alert('downloading!') //Your Download Logic HERE
$(this).parent().trigger('submit')//Trigger Form SUBMIT ONCE THE OPERATION IS DONE
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form name="test" action="action.php" method="get">
<input type="text" />
<input type="button" value="download" class="download"></form>
Firstly note that <form> elements are not self closing, so your current HTML is invalid; the input elements need to be within the form itself.
Once that is fixed you can trigger() a submit event on the parent form to the #button element, like this:
$('#button').click(function() {
console.log('Custom logic here...');
$(this).closest('form').trigger('submit');
});
$('form').on('submit', function(e) {
e.preventDefault();
console.log('Submitting form...');
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form name="test" action="action.php" method="get">
<input type="text" />
<input type="submit" value="search" />
<input type="button" value="download" id="button" />
</form>
You can simply submit your form by javascript, after clicking download button:
$('#button').click(function(){
...
document.forms["myform"].submit();
I've got on my index.php form with POST method.
Action is form.php, so it's different file, but I'm using iframe to show my result, still being at index.php.
One more thing that I need, is to show one of my text inputs, still on index.php, when I do click submit button. I've tried to use onClick action:
<script type="text/javascript">
function showamount()
{
var price = document.getElementById('amount').value;
document.getElementById("some_p").innerHTML = price;
}
</script>
<input type="text" id="amount" />
<input type="submit" value="Podlicz" onclick="showamount()" />
<p id="some_p"></p>
It does not work there, when submit button is dedicated to form, with an action (I suppose, because it works without form, when is pure like above)
What is wrong? Thanks!
Try this <form id="form" onSubmit="return showamount();" action="form.php" target="_blank">
That will open a new window to run the form.php and will also update current page with inputed value.
javascript
<script>
function showamount()
{
var price = document.getElementById('amount').value;
document.getElementById("some_p").innerHTML = price;
return true;
}
</script>
html
<form id="form" onSubmit="return showamount();" action="form.php" target="_blank">
<input type="text" id="amount" />
<input type="submit" value="Podlicz" onclick="showamount()" />
</form>
<p id="some_p"></p>
I have a form in which there is one text field is provided with a submit button.On clicking submit button,it redirects to second php page from first php page.
index.php
<form action="submit.php" method="get">
<input type="text" name="search" id="search" />
<input type="submit" value="submit" onclick="convert()" />
</form
<script type="text/javascript">
function convert()
{
alert("hi");
var str ;
str = document.getElementById("search").value;
document.writeln(str.toLowerCase());
}
</script>
On submitting the form,i want the url to become like submit.php?search=text
I want this text to be in lower case,although if text entered is uppercase.
Please guide me how to make this text lower case,I am using the above script for converting it to lower case.But its not converting the text in lower case in URL.
Please guide me on this..
There was a few errors, you were missing the right angle bracket on </form> and you were trying to write the value rather than setting the field value, try this...
<form action="submit.php" method="get">
<input type="text" name="search" id="search" />
<input type="submit" value="submit" onclick="convert();" />
</form>
<script type="text/javascript">
function convert() {
alert("hi");
var str;
var srch=document.getElementById("search");
str = srch.value;
srch.value=str.toLowerCase();
}
</script>
You can do this only using javascript with a few extra stuff:
1) Give your <form> an id
<form action="submit.php" method="get" id="form1">
2) Make your <input> type as button. The reason for this is because we want to make sure the convert() function is executed first, and after that we will submit the form.
<input type="button" value="submit" onclick="convert()" />
3) Finally javascript to:
function convert()
{
alert("hi");
var str ;
str = document.getElementById("search");
str.value = (str.value.toLowerCase());
//get the form id and submit it
var form = document.getElementById("form1");
form.submit();
}
Fiddle
You are use form element so you can get any elements inside form element access by name, Here Our form name is form1 and inside this form inputbox name="search" and access this value by this way, document.form1.search.value.toLowerCase();
Check this Demo jsFiddle
JavaScript
function convert() {
alert("hi");
var str = document.form1.search.value.toLowerCase();
document.writeln(str);
//console.log(str);
}
HTML
<form name="form1" method="get">
<input type="text" name="search" id="search" />
<input type="submit" value="submit" onclick="convert();" />
</form >
try like this:
alert("hi");
document.getElementById("search").value = document.getElementById("search").value.toLowerCase();
return true;

I have multiple forms in my php file for different buttons. So, if I click on Back button, ramesh.php script should be called and so on. This is the code.
<form action="ramesh.php">
<input type="submit" value="Back" />
</form>
<form action="process.php" method="post">
<input name="rep_skyline" type="text" />
<input type="submit" />
</form>
<form action="update.php" method="post" >
<button type="submit">Update</button>
</form>
However, I need to pass some data to server from my client side on form submit just for the update button. I have a javascript function to send the data to server side as below.
<script type="text/javascript">
$(document).ready(function() {
$('form').submit(function(e) {
var mydata = 3;
if ($(this).is(':not([data-submit="true"])'))
{
$('form').append('<input type="hidden" name="foo" value="'+mydata+'">');
$('form').data('submit', 'true').submit();
e.preventDefault();
return false;
}
})
})
</script>
If I click on the update button, the javascript function is working fine. However, if I click on Back or Submit button, I should not be calling the javascript function. Is there someway to do this?
Give your form an id:
<form action="update.php" method="post" id="update-form">
Then use a more specific selector:
$("#update-form").submit(function() {
// Code
});
I'm not quite sure why you need JavaScript to dynamically add data to your form, however. You should just use an <input type="hidden" /> directly.
type=submit will always load the form's action. Try to specify wich form to submit.
<form name="backForm" id="backForm" action="ramesh.php">
<input type="submit" value="Back" />
</form>
<form name="form2" id="form2" action="process.php" method="post">
<input name="rep_skyline" type="text" />
<input type="submit" />
</form>
Now you can access the form via document.backForm or document.getElementById("backForm") and than use submit(); like document.getElementById("backForm").submit();
