Html Textinput in Table Data

Our teacher want us to create a website that will recieve text from the user (textfield) and send it to table data and it need to be in <form>
When i use <form> i input text in textfield the text and submit it the text that i enter is showing in table data at the same time its gone like in the text field i know that this is because of <form> when i remove the <form> the text is showing in table data.
Here is my code :
<form>
Name: <input action="f1.document.getElementById("first_name");" id="first_name" size="30" type="text" >
<button class="okok" name="myBtn" type="submit" value="Submit Data" onClick="ajax_post();">COMPUTE </button>
</form>
<table>
<tr>
<td style="color:white;" id=f1 > </td>
</tr>
</table>
in script
:
function ajax_post(){
var fn = document.getElementById("first_name").value;
var table = document.getElementById("f1");
table.innerText = fn;
}

That's because the button is 'submitting' the form, which is like refreshing to page in that it will clear the values.
You have to stop the form submitting, like this:
<form onsubmit="return false;">

Input fields get (readonly) after hit submit button

I have a script which is coded in PHP and smarty and I want to make some changes in this script like in user profile setting when a user click on profile setting and fill the profile data like (full name , email , bank account number , bank name , branch code , tile etc) after fill this information and click the save button the script save all setting but I want to make some of form input fields (readonly) after user submitted his/her data I want make this data (readonly) (bank name , account number , branch code , title) I mean about readonly that after user fill this and save it in profile its show to user (readonly) user can't change it only I can change it from database .
Below is the form code
<form id="settingsform" onsubmit="return submitform(this.id);">
<input type="hidden" name="a" value="submit" />
Bank Name:
</td>
<td><input type="text" name="bank" id="bank" value="{$user_info.bank}"></td>
</tr>
<tr>
<td align="right" width="50%">
Bank Account Number:
</td>
<td><input type="text" name="baccount" id="baccount" value="{$user_info.baccount}"></td>
</tr>
<tr>
<td align="right" width="50%">
Bank Account Title:
</td>
<td><input type="text" name="btitle" id="btitle" value="{$user_info.btitle}"></td>
</tr>
<tr>
<td align="right" width="50%">
Bank Branch Code:
</td>
<td><input type="text" name="bcode" id="bcode" value="{$user_info.bcode}"></td>
</tr>
<input type="submit" name="btn" value="{$lang.txt.send}" class="orange" />
also i am already trying like this below
<script>
function hide(){
document.getElementById("bank").disabled = true;
document.getElementById("baccount").disabled = true;
document.getElementById("btitle").disabled = true;
document.getElementById("bcode").disabled = true;
}
</script>
and
<input type="button" onClick="hide()" value="save">

<input type="text" name="country" value="Norway" readonly>
http://www.w3schools.com/tags/att_input_readonly.asp
Then simply do a check if the POST/GET is set for the field you want to have readonly on ->
<input type="text" name="country" value="Norway" <?php isset($_POST['country']) ? echo 'readonly' : ''; ?> >
UPDATE
<input type="text" name="country" value="Norway" <?php isset($user_info.bank) ? echo 'readonly' : ''; ?> >
Just replace the variable inside of the isset() with the variable of the field, depending on how you initialize the variables you might need to use
empty()
instead, to do so just simply replace isset() with !empty()
The reason for the ! sign is to tell the code to execute the first bit (the echo part) if the variable ISN'T empty
UPDATE 2
<input type="text" name="country" value="Norway" {if isset($user_info.bank) } readonly {/if} >
Above code should work with smarty how ever, the idea is simple, simply have a "if" sentence that checks whether the variable is set/have data, and if it does, then echo 'readonly' in the input field

Try to use attr() in submitform() like,
function submitform(id){
....
....
$('#bank,#baccount').attr('readonly','readonly');
return false;
}
Updated,
function hide(){
$("#bank,#baccount,#btitle,#bcode").prop('disabled', true);
}
Or try,
function hide(){
$("#bank,#baccount,#btitle,#bcode").attr('disabled', 'disabled');
}

Adding a item into a cart automatically using javascript

Hi i have a cart that i want to add a form automatically this code seems to kinda do the trick only the problem is i have to hit F5 for it to add the amount i am quite new to this and cant figure out where i have gone wrong.
<form method="post" action="level3.php" class="jcart" id="foo">
<fieldset>
<input type="hidden" name="jcartToken" value="<?php echo $_SESSION['jcartToken'];?>" />
<input type="hidden" name="my-item-id" value="ABC-8" />
<input type="hidden" name="my-item-name" value="Level 1" />
<input type="hidden" name="my-item-price" value="95.00" />
<input type="hidden" name="my-item-url" value="" />
<table>
<tr>
<td width="65%">
<strong>Level 1 all for £95</strong>
</td>
<td width="15%" align="right">
£95.00
</td>
<td>
<input type="text" hidden ="true" name="my-item-qty" value="1" size="3" hidden="true" />
</td>
<td width="20%" align="center">
<input type="submit" name="my-add-button" id="my-add-button" value="add" class="button" />
</td>
</tr>
</table>
<input type="hidden" name="visited" value="" />
</fieldset>
That is the form that submits the amount into the check out.
<script>
$(document).ready(function(){
//Check if the current URL contains '#'
if(document.URL.indexOf("#")==-1)
{
url = document.URL+"#";
location = "#";
} else {
location.reload(true);
document.getElementById("my-add-button").click();// Simulates button click this has to be in as it links to another piece of java that adds the item to the check out with out this it wont add the item
document.foo.submit(); // Submits the form without the button
}
});
</script>
document.getElementById("my-add-button").click();
The code above links to the code below that adds the items from to my knowledge
$('.jcart').submit(function(e) {
add($(this));
e.preventDefault();
});
Thank you in advance for any help or suggestions

If i understand correctly, you increase some value of cart in PHP and than want to update quantity on page without refreshing page.
I made little JSFiddle: http://jsfiddle.net/7SbBA/
Basically use ajax:
$.ajax({
url: 'example.com',
data: /* pass product id here */
success: function(){
/* update quantity you want */
}
});
There is some html change too.
UPDATE
If you want updated total values on page load, just £<span class='amount'><?php echo $product['quantity'] * $product['price'] ?></span> and there is no need to use jquery/js for that. But if you still want dynamically update on window load, i updated my JSFiddle v.2

Forms inside td html

My html code is:
<table><tr><td onclick="submit_form_patient();")>
<form name="select_patient" method="POST" action="./select_bed.php">
<input name="raw_data" type="hidden" value="27" />27</form>
</td></tr>
<tr><td onclick="submit_form_patient();")>
<form name="select_patient" method="POST" action="./select_bed.php">
<input name="raw_data" type="hidden" value="49" />49</form></td></tr>
My Java script is:
<script>
function submit_form_patient()
{
document.forms["select_patient"].submit();
}
</script>
My form gets submitted but if I use $_POST to retrieve the values I get 27 all the time namely the first value I never get the other values.

Yours forms have same name. You need to name them differently.
And modify js code:
<script>
function submit_form_patient(formName)
{
document.forms[formName].submit();
}
</script>
And html code need to be like this
<table>
<tr>
<td onclick="submit_form_patient('select_patient');")>
<form name="select_patient" method="POST" action="./select_bed.php">
<input name="raw_data" type="hidden" value="27" />27</form>
</td>
</tr>
<tr>
<td onclick="submit_form_patient('select_patient2');")>
<form name="select_patient2" method="POST" action="./select_bed.php">
<input name="raw_data" type="hidden" value="49" />49</form>
</td>
</tr>

The name of the forms is the same. I don't know whether the standard handles this, but browsers pick the first matching item. So it's always going to be the first.
Create only one form, and based on the click POST the right value.

When you use document.forms["select_patient"].submit();, JS will find first form/element with that name.

Try this:
<script>
function submit_form_patient()
{
document.getElementsByName("select_patient")[0].submit();
document.getElementsByName("select_patient")[1].submit();
}
</script>
you can also create a for block to be more consistent.

Selecting a checkbox in html table containing handlebar, expressjs

I have a html table in a form in which the rows of table are populated using handebars. I want to select some rows of the table using checkbox. The form makes a post request. I am using express.js framework for the same. The requiremment is that when the form is submitted the json should have a field named 'checked' which should have value true or 1 if the row was selected. Please help me in solving the issue.
Following is the snippet of the html
<form id='form1'>
<table border="1">
{{#each ElectrnicsResults}}
<tr>
<td>{{Product}}</td>
<td>{{Description}}</td>
<td>{{price}}</td>
<td>{{quantity}}</td>
<td>
<input type='checkbox' id="check">
</td>
<td style="display:none">
<input type="hidden" name="electronicsId" value="{{electronicsId}}" />
<input type="hidden" name="Product" value="{{Product}}" />
<input type="hidden" name="Description" value="{{Description}}" />
<input type="hidden" name="price" value="{{price}}" />
<input type="hidden" name="quantity" value="{{quantity}}" />
</td>
</tr>
{{/each}}
</table>
<input type="submit" value="submit" >
</form>
Following is the javascript code using JQuery
$(document).ready(function () {
$('#form1').submit(function() {
$.ajax({
url: '/submitValues',
type: 'post',
dataType: 'json',
data: $('#form1').serialize(),
success: function() {
alert("Submitted!"); // for testing
}
});
return false;
});
});

Since the form is created dynamically, you'll have to parse the results dynamically as well.
First, you'll want to attach a name field to each input type=checkbox element. This name needs to be unique to each ElectrnicsResults (perhaps something like the ID field).
Then, in your backend code when parsing the form details, you'll can again loop through each relevant ElectrnicsResults and check the req.body.{UNIQUE_NAME_FIELD_VALUE} for each checkbox, and act accordingly.
