Hi i'm not a programmer and i need a javascript code.
I want to pass the URL parameter to a hidden form field!
This is what is added to the URL:
?ref_id=ik20284953
So i want to get the REF_ID and get it into a hidden field of a form which i already have.
How exactly can i do it ?
I found some solutions here in the forum but nothing worked for me!
HELP IS MUUUUCH APPRECIATED!
Greetings
Matthias
EDIT:
THIS IS MY FORM:
<div id="form-163709-wrapper">
<form id="ktv2-form-163709" accept-charset="UTF-8" method="post" action="https://www.klick-tipp.com/api/subscriber/signin.html"><input type="hidden" id="FormField_ApiKey" name="apikey" value="3smez1c7gz8ze9db" /><input type="hidden" id="FormField_Digit" name="fields[fieldDigit]" value="" />
<div class="ktv2-form-element"><label for="FormField_EmailAddress">Ihre E-Mail-Adresse: </label><br /><input type="text" id="FormField_EmailAddress" name="email" value="" size="40" /></div>
<div class="ktv2-form-element"><label for="FormField_FirstName">Vorname: </label><br /><input type="text" id="FormField_FirstName" name="fields[fieldFirstName]" value="" /></div>
<div class="ktv2-form-element"><input type="hidden" id="FormField_81808" name="fields[field81808]" value="" /></div><br />
<div><input type="submit" id="FormSubmit" name="FormSubmit" value="Ihr Button-Text" /></div>
</form>
</div>
You can get the ref_id with the URLSearchParams().get(), then you can inject the value with setAttribute()
var urlParams = new URLSearchParams(window.location.search);
var myParam = urlParams.get('ref_id');
document.getElementById('FormField_81808').setAttribute('value',myParam)
<form>
<input type="hidden" id="FormField_81808">
</form>
First you need to parse the query string, you can check this post: Parse query string in JavaScript
And then if you are using jQuery,
$("#FormField_81808").val(parsed_value);
If it is a native javascript that you are using;
document.getElementById("FormField_81808").value = parsed_value;
PS: It is best to put some code when you are trying to get an answer to this type of questions.

I'll start this off by saying I use JS very infrequently, so this is likely a simple mistake. I came across the need to generate a form on the spot when a button is pressed. After some searching, I decided on using the append function from jQuery. Here is the code I wrote:
function replyToComment(commentId) {
var element = document.getElementById("reply-form");
if (element != null) {
element.remove()
}
const html = `
<div id="reply-form">
<label for="comment-form">Comment:</label>
<form method="post" id="comment-form" style="padding-bottom: 10px;">
<input type="hidden" name="csrfmiddlewaretoken" value="${csrf_token}"
<div class="form-group">
<div>
<textarea type="text" name="body" maxlength="1500" class="textarea form-control" cols="40" rows="10"></textarea>
</div>
</div>
<input type="text" name="comment-send" style="display:none;" readonly>
<input type="text" name="comment_id" value=${commentId} style="display:none;" readonly>
<button type="submit" class="btn btn-success">Send</button>
</form>
</div>`
$(`#${commentId}`).append(html)
}
When inspecting the final result, the argument passed into the append function is out of order:
I am not sure if the image will load in properly, but if it doesnt, its mostly irrelevant. Am I misusing the append function? Is there another way to do this that will handle the data I want to pass in properly?
It appears that you're neglecting to close one of your input tags.
You have:
<input type="hidden" name="csrfmiddlewaretoken" value="${csrf_token}"
This should be:
<input type="hidden" name="csrfmiddlewaretoken" value="${csrf_token}" />
I know it's a silly question of this type, but im new to JS and im learning coding step by step. I'm curious how would i set up sessions for input values in javascript if i have this type of coding?
<input type="text" id="name" >
<input type="text" id="lastname">
<input type="submit" value="submit" id="btn">
Again i want to apologize for this question , and thank you for the help that you can offer me about this .
Now this code had help me out.What i wanted to do is to store the values of the input fields into sessions and be able to display them into the browser likethis:
<body>
<input type="text" id="name" ><br><br>
<input type="text" id="lastname"><br><br>
<input type="submit" id="btn" value="set sessions"><br><br>
<p id="para"></p>
<script>
var btn=document.getElementById("btn");
btn.onclick=function(){
var name=document.getElementById("name").value;
var lastname=document.getElementById("lastname").value;
sessionStorage.setItem("name",name);
sessionStorage.setItem("lastname",lastname);
document.getElementById("para").innerHTML=sessionStorage.getItem("name")+"
"+sessionStorage.getItem("lastname");
}
</script>
</body>
I have a form as follows:
<form name="chat" id="chat" action="" onsubmit="sendMessage()">
<a name="chat"> </a>
<input type="text" name="chat" id="chat" size="38" maxlength="50" vertical-align="middle">
<input type="hidden" name="action" id="action" value="checkresponse">
<input type="hidden" name="response_Array[sessionid]" id="response_Array[sessionid]" value="keu88lh88ini89dgnccob54f27"><br>
<input type="text" name="response_Array[top]" id="response_Array[top]" value="a">
<input type="text" name="response_Array[second]" id="response_Array[second]" value="b"><br>
<input type="text" name="response_Array[third]" id="response_Array[third]" value="c"><br>
<input type="text" name="response_Array[fourth]" id="response_Array[fourth]" value="d"><br>
<input type="text" name="response_Array[input][0]" id="response_Array[input][0]" value="input 0"><br>
<input type="text" name="response_Array[that][0]" id="response_Array[that][0]" value="that 0"><br>
<input type="submit" name="submit" id ="submit" value="SEND" style="width: 45px">
</form>
When the user clicks Submit, I need to send all the input fields to the server.
But, the page should not get refreshed. So, I have created sendMessage(),in which I have used XMLHttpRequest object to send the form submit request.
To read input fields, I have used in sendMessage():
var infoStr = "chat="+document.forms[0]['chat'].value;
infoStr += "&action="+document.forms[0]['action'].value;
I want to know how should I read the 2D array :response_Array and parse it into a JSON string so that it can be passed to the php server code.
It is so simple
var infoStr=""
for(var i=0;i<document.forms[0].elements.length;i++)
{
infoStr+=document.forms[0].elements[i].name+"="+document.forms[0].elements[i].value+"&";
}
alert(infoStr); // You will have the full name value pairs.
Hope this solves your problem.

I want to pass the value from the gsearch to the q parameter. The following is the ways I make but it couldn't work. How should I do it?
action="http://test.com/search.php?q=<script type="text/javascript">document.getElementById('gsearch').value;</script>">
updated:
in my site. i want to make a google custom search: so i put the following code in the homepage. 0156290304977:8texhu0mrk the google search value. gsearch.php page which i put the google custom search code in and show the searched result
<form method="get" action="http://test.com/gsearch.php?cx=0156290304977:8texhu0mrk&cof=FORID:11&ie=UTF-8&q=..." >
<input type="text" title="" value="" name="q" class="search-input" id="gsearch" />
<input type="submit" value="" name="sa" id="search-button"/>
</form>
now, i want to when the user input the searched text in the gsearch text box, if he click the submit button,. then on the gsearch.php page shows the searched result.
if you want to submit to this: http://test.com/search.php?q=theinput
just do this:
<form target="_top" method="get" action="http://www.cnn.com/search.php" >
<input type="text" title="" value="theinput" name="q" class="search-input" id="gsearch" />
<input type="submit" value="submit" id="search-button"/>
</form>
the entire idea behind the <form> element is that it is making sure that all of the inputs from the user will be sent to the action.
the form will take the input from the q and add it to the action automatically.
so in your simple case. no manipulation is required.
Test it here
http://jsfiddle.net/L4rHG/1/
this will be submitted to http://edition.cnn.com/search.php?q=theinput
Or you need over javascritpt
<script>
function SubmitForm(){
window.open("http://test.com/search.php?q="+document.getElementById('gsearch').value)
return false;
}
</script>
<form method="get" action="http://test.com/search.php" onSubmit="SubmitForm();false" >
<input type="text" title="" value="" name="q" class="search-input" id="gsearch" />
<input type="submit" value="" name="sa" id="search-button"/>
</form>
<form action="http://test.com/search.php?q=">
<script>
document.forms[0].action += 'new_action.html';
</script>
I'm using the jQuery .serialize function and can't get it to serialize the proper form on submit.
my js code:
function getquerystring(form) {
return $("form").serialize();
}
my forms:
<div class="leave_message_box">
<form name="leave_message_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="leave_message" />
<input value="Leave Message" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "leave_message_form")'></p>
</form>
</div>
<div class="outside_job_box">
<form name="outside_job_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="ouside_job" />
<input value="Outside Job" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "outside_job_form")'></p>
</form>
</div>
I must be doing something wrong in passing the variable. the full code # pastie. The function I have does work, however, its always the last form that gets submitted.
Using this code:
$("form")
will find all the <form> elements in your document.
Given that form is a string containing the name of the form, what you want instead is this:
$("form[name='" + form + "']")
Looking at your supplied code, I have this suggestion. Instead of passing the form name to your function, why not just pass the form itself?
<button onclick="xmlhttpPost('blah', this.form)">
You also don't need to put javascript: in the onclick, onfocus, onwhatever properties.
I would suggest putting an ID attribute on the form and then using that ID as an explicit selector for jQuery:
<div class="outside_job_box">
<form id="outside_job_form" name="outside_job_form">
<input type="text" name="clock_code" placeholder="Clock Code" />
<input type="text" name="message" placeholder="Message (Blank for none)"/>
<input type="hidden" name="type" value="ouside_job" />
<input value="Outside Job" type="button" onclick='JavaScript:xmlhttpPost("clockin.php", "outside_job_form")'></p>
</form>
</div>
Then you would select and serialize it like this;
var f = $("#outside_job_form").serialize();
Not only making your code more effecient but more readable, in my opinion.
If the sole purpose is to encode simple text into URL format then use encodeURIComponent().
