I have a HTML form as follows:-
<form name="login" id="login" action="<%=application.getContextPath()%>/GoogleLogin" method="get">
<input type=hidden id="firstName"/>
</form>
I am setting the values of this hidden input type in javascript and submitting the form to servlet as follows:-
<script>
document.getElementById("firstName").value="XYZ";
document.getElementById("login").submit();
<script>
My form is getting submitted but I am not able to get the request parameter "firstName".
http://localhost:8080/Login/GoogleLogin?
Thank you for your time and consideration.
Add a name attribute to the input field -
<input type="hidden" id="firstName" name="firstName" />
then you'll be able to get the request parameter using firstName.

When I submit form by using below function it is submitting but values are not passed through this function. I use all functions but nothing found:
document.getElementById("postad").submit();
Form is given below.
<form action="register.php" id="postad" method="post">
<input class="textfield2" type="text" id="post_title" style="width:640px;" placeholder="Ad Title" onBlur="check('post_title')" />
<input class="button" type="button" name="save" value="Publish" onclick="send();" />
</form>
Your form contains two form controls. Neither will be a successful control (i.e. one that appears in the submitted data), but for different reasons.
Only form controls with name attributes can be successful. Your text input doesn't have a name. (It also doesn't have a default value, so you need to type in it first).
Buttons can only be successful if they are the submit button used to submit the form. Your button isn't a submit button and you use JavaScript to submit the form.
There is no name attribute in your input text fields
<input name="post_title" class="textfield2" type="text" id="post_title" style="width:640px;" placeholder="Ad Title" onBlur="check('post_title')" />

I've a problem with my form. I want to make standard PHP form but AngularJS is blocking the "Submit" button.
When I click the "Submit" button, it returns some errors in console. And remember I don't want to dynamically submit.
The error is:
An invalid form control with name='' is not focusable.
This example
<body ng-app="mainApp">
<form action="post.php" method="post">
<div ng-controller="MainCtrl">
<label for="titlex">Title</label>
<input id="titlex" class="form-control" type="text" maxlength="75" min="10" name="titlex" required>
</div>
<input type="submit" value="Send">
</form>
</body>
This issue pops up in different cases:
You have a hidden form element that has a required attribute for validation.
You hide an form element before send your data.
Some required form elements does not have a name attribute.
Your submit input does not have a name attribute.
You can try to add a name attribute to your submit input:
<input type="submit" value="Send" name="send">
or you can setup your form to be not validated by the browser mechanics by using
<form name="myform" novalidate>
Try adding name attribute in input tag.
Only form elements with a name attribute will have their values passed when submitting a form.
<input type="submit" value="Send" name="send">
Hope this solves your problem.
I'm trying to get the search term to appear in the URL. What am I doing wrong?
<form name="catsearchform74255" method="post" onsubmit="processSearch(this)" action="/Default.aspx?SiteSearchID=2248&ID=/search-results&keywords=">
<div class="input-field search-box">
<input id="CAT_Search" type="search" name="CAT_Search" placeholder="What are you looking for?" class="white" required="true">
<label class="label-icon" for="CAT_Search"><i class="material-icons">search</i></label>
<i class="material-icons">close</i>
</div>
<script type="text/javascript">
function processSearch(form) {
form.action = form.action + CAT_Search.value;
}
</script>
</form>
Change method="post" to method="get".
Update any server-side code referencing post variables to reference get variables. For example, in PHP code, change $_POST["CAT_Search"] to $_GET["CAT_Search"].
Also, the correct format for the required HTML attribute is either required="" or required="required.
Code
This can be done with JS, you can't edit the method as Business Catalyst expects a post for this form.
If you change the form to the following:
<form name="catsearchform74255" id="searchForm" method="post" action="/Default.aspx?SiteSearchID=2248&ID=/search-results&keywords=">
<div class="search-box">
<input class="cat_textbox_small" type="text" name="CAT_Search" id="CAT_Search">
<input id="submitForm" onclick="submitFormScript()" type="button" class="cat_button" value="Search">
</div>
</form>
and then add the following jQuery:
function submitFormScript() {
var searchAction = $("#searchForm").attr("action");
searchAction = searchAction + $("#CAT_Search").val();
$("#searchForm").attr("action", searchAction);
$("#searchForm").submit();
}
Explanation
By adding the ID's to the fields on the form and then taking type="submit" off the input button we can edit the form action before we submit the form.
In the JS we are getting the form action, adding on the value of the search box (users input) and then setting that back to the form action attribute. After that we have the URL that we want to send to the next page so we can then submit the form.
I'm trying to post a value to another HTML-document by a hidden input. Then I want to recieve the value with location.search and do something in the new HTML-document. The problem is that the doucment is opening, but the value isn't sent. Here is the HTML:
<form action="britzcwka.html" method="post" id="formID">
<input id="inpt" type="hidden" name="myInput" value="">
</form>
And here is the JavaScript-code:
document.getElementById("inpt").value = someValue;
alert(document.getElementById("inpt").value);
document.getElementById("theForm").submit();
The alert shows the correct value, but the address url is just britzcwka.html when on the other page.

You're using POST method, so your variables will not be included in the browser's address bar. Change form's method to GET:
<form method="GET" action="britzcwka.html" id="formID">
<!-- form's content -->
</form>
I have two forms in a JSP page, one contains a text field. I need to make sure that whenever the other form is submitted, it copies the value contained in that text field, and writes it's text value in an hidden parameter.
More clearly:
One form is named "search";
Another form is named "changeInitialForm";
The text field is contained in the "search" form, and it's name is "searchString";
The "changeInitialForm" has an hidden field, also this named "searchString";
The purpose is to make sure that whether the user submits one or another form, a "searchString" parameter is passed, with the value of the text field.
I tried to include an action in javascript, executed when the "changeInitialForm" is submitted, that reads the text field value and writes it into the hidden parameter:
function searchContacts(form)
{
var searchString= document.search.searchString.value;
form.searchString.value= searchString;
}
...
<form name="search" >
<input type="text" name="searchString">
<button name="search"> Cerca </button>
</form>
...
<form name="changeInitialForm" method="post" action="AddressBookView.jsp" onSubmit="searchContacts(this.form);">
<input type="hidden" name="selectedInitial"/>
<input type="hidden" name="status" value="view"/>
<input type="hidden" name="searchString" />
</form>
But after the "changeInitialForm" is submitted, regardless of the text field value, and empty parameter is passed, I am seeing this with firebug:
I would also appreciate an alternative solution, because I know what I am doing is tricky, but I don't find another method to do that. "search" and "changeInitialForm" cannot be joined in a single form, because they do very different things.
The following seems to work
function searchContacts(form)
{
var searchString= document.search.searchString.value;
form.searchString.value= searchString;
}
...
Form 1:
<form name="search" >
<input type="text" name="searchString">
<button name="search"> Cerca </button>
</form>
...
Form 2:
<form name="changeInitialForm" method="post" action="AddressBookView.jsp" onSubmit="searchContacts(this);">
<input type="hidden" name="selectedInitial"/>
<input type="hidden" name="status" value="view"/>
<input type="hidden" name="searchString" />
</form>
Notice that searchContacts(this.form) was replaced with searchContacts(this).
UPDATE after some precisions by the author of the question:
The onsubmit event is not triggered when form.submit() is called by some javascript code. Thus, what you need when you submit the form is to call searchContacts separately, for example using
searchContacts(document.changeInitialForm);
document.changeInitialForm.submit();
