I'm seeing this in our templates. They say it's so the code can be tested but it still seems wrong to me:
<tr ng-repeat="comp in collection">
<td>
<span id="someId">{{comp.someText}}</span>
</td>
....
I'm thinking we should be using name instead.
If you really need unique IDs inside the repeater, try this:
<tr ng-repeat="comp in collection">
<td>
<span id="someId{{$index}}">{{comp.someText}}</span>
</td>
So if, for instance, you need to link labels to inputs in the ngRepeat:
<tr ng-repeat="comp in collection">
<td>
<label for="field{{$index}}">{{field.label}}</label>
<input type="text" id="field{{$index}}" ng-model="field.value" />
</td>
This approach is especially useful if you need to have check boxes with clickable labels inside the ngRepeat.
Basically, I have a table with inputs inside a form tag, that are required by user to fill in.
When I test it, the form is working, but only when there is one row in a table. With two an more rows, a required attribute is not working.
I've written a simple example
This works, click enter inside input field to see.
<form>
<table>
<tr>
<td>
<input type="text" name="usrname" required>
</td>
</tr>
</table>
</form>
<br>
This doesn't work, click enter inside input field to see.
<form>
<table>
<tr>
<td>
<input type="text" name="usrname" required>
</td>
</tr>
<tr>
<td>
<input type="text" name="surname" required>
</td>
</tr>
</table>
</form>
That's because forms with more than one text input aren't submitted by hitting enter. Try adding a submit button to both forms and you'll see it works fine.
In your example, is that supposed to be two identical fields in the different cells (and one of them is just misspelled)? If so, that's likely your problem. If they are intended to be two separate fields, it should work, but I'd need to see a more real-world example.
Also, I'd highly recommend using CSS to format/style your form. If that sounds intimidating, try Bootstrap--it makes creating pretty forms extremely easy.
This code I have written will generate lines in between every row and column. Can you please tell me how can I remove some lines in between columns while keeping others (as shown in the last image).
<form action="method="POST">
<table border="1" style="width:400px">
<tr>
<td>January:</td>
<td>$20</td>
<td>february:</td>
<td>$30</td>
<td>March:</td>
<td>$60</td>
</tr>
<tr>
<td>April:</td>
<td>$20</td>
<td>May:</td>
<td>$30</td>
<td>June:</td>
<td>$60</td>
</tr>
<tr>
<td>Description:</td>
<td colspan="5"><input type="text" name="data" value="some data" size="44"/></td>
</tr>
</table>
<input type="submit" name="updatebutton" value="Update" /></form>
You can't. That's just how tables work.
Alternately you can remove the borders from the table, put a DIV in each cell and selectively style the borders of the DIVs.
I'm trying to create a table where each row is a form. I want that each input is in a different table division, but I still need that for example, all first inputs belong to the same table head and so on.
What I'm trying to do is an editable grid, more or less this:
<table>
<tr>
<form method="POST" action="whatever">
<td><input type="text"/></td>
<td><input type="text"/></td>
</form>
</tr>
<tr>
<form method="POST" action="whatever">
<td><input type="text"/></td>
<td><input type="text"/></td>
</form>
</tr>
</table>
But apparently I cannot arrange the tags in that way (or so is what the w3c validator said).
Any good way to do this?
If you want a "editable grid" i.e. a table like structure that allows you to make any of the rows a form, use CSS that mimics the TABLE tag's layout: display:table, display:table-row, and display:table-cell.
There is no need to wrap your whole table in a form and no need to create a separate form and table for each apparent row of your table.
Try this instead:
<style>
DIV.table
{
display:table;
}
FORM.tr, DIV.tr
{
display:table-row;
}
SPAN.td
{
display:table-cell;
}
</style>
...
<div class="table">
<form class="tr" method="post" action="blah.html">
<span class="td"><input type="text"/></span>
<span class="td"><input type="text"/></span>
</form>
<div class="tr">
<span class="td">(cell data)</span>
<span class="td">(cell data)</span>
</div>
...
</div>
The problem with wrapping the whole TABLE in a FORM is that any and all form elements will be sent on submit (maybe that is desired but probably not). This method allows you to define a form for each "row" and send only that row of data on submit.
The problem with wrapping a FORM tag around a TR tag (or TR around a FORM) is that it's invalid HTML. The FORM will still allow submit as usual but at this point the DOM is broken. Note: Try getting the child elements of your FORM or TR with JavaScript, it can lead to unexpected results.
Note that IE7 doesn't support these CSS table styles and IE8 will need a doctype declaration to get it into "standards" mode: (try this one or something equivalent)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Any other browser that supports display:table, display:table-row and display:table-cell should display your css data table the same as it would if you were using the TABLE, TR and TD tags. Most of them do.
Note that you can also mimic THEAD, TBODY, TFOOT by wrapping your row groups in another DIV with display: table-header-group, table-row-group and table-footer-group respectively.
NOTE: The only thing you cannot do with this method is colspan.
Check out this illustration: http://jsfiddle.net/ZRQPP/
If all of these rows are related and you need to alter the tabular data ... why not just wrap the entire table in a form, and change GET to POST (unless you know that you're not going to be sending more than the max amount of data a GET request can send).
(That's assuming, of course, that all of the data is going to the same place.)
<form method="POST" action="your_action">
<table>
<tr>
<td><input type="text" name="r1c1" value="" /></td>
<!-- ... snip ... -->
</tr>
<!-- ... repeat as needed ... -->
</table>
</form>
You may have issues with column width, but you can set those explicitly.
<table>
<tr>
<td>
<form>
<table>
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
</table>
</form>
</td>
</tr>
<tr>
<td>
<form>
<table>
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
</table>
</form>
</td>
</tr>
</table>
You may want to also consider making it a single form, and then using jQuery to select the form elements from the row you want, serialize them, and submit them as the form.
See: http://api.jquery.com/serialize/
Also, there are a number of very nice grid plugins:
http://www.google.com/search?q=jquery+grid&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a
If using JavaScript is an option and you want to avoid nesting tables, include jQuery and try the following method.
First, you'll have to give each row a unique id like so:
<table>
<tr id="idrow1"><td> ADD AS MANY COLUMNS AS YOU LIKE </td><td><button onclick="submitRowAsForm('idrow1')">SUBMIT ROW1</button></td></tr>
<tr id="idrow2"><td> PUT INPUT FIELDS IN THE COLUMNS </td><td><button onclick="submitRowAsForm('idrow2')">SUBMIT ROW2</button></td></tr>
<tr id="idrow3"><td>ADD MORE THAN ONE INPUT PER COLUMN</td><td><button onclick="submitRowAsForm('idrow3')">SUBMIT ROW3</button></td></tr>
</table>
Then, include the following function in your JavaScript for your page.
<script>
function submitRowAsForm(idRow) {
form = document.createElement("form"); // CREATE A NEW FORM TO DUMP ELEMENTS INTO FOR SUBMISSION
form.method = "post"; // CHOOSE FORM SUBMISSION METHOD, "GET" OR "POST"
form.action = ""; // TELL THE FORM WHAT PAGE TO SUBMIT TO
$("#"+idRow+" td").children().each(function() { // GRAB ALL CHILD ELEMENTS OF <TD>'S IN THE ROW IDENTIFIED BY idRow, CLONE THEM, AND DUMP THEM IN OUR FORM
if(this.type.substring(0,6) == "select") { // JQUERY DOESN'T CLONE <SELECT> ELEMENTS PROPERLY, SO HANDLE THAT
input = document.createElement("input"); // CREATE AN ELEMENT TO COPY VALUES TO
input.type = "hidden";
input.name = this.name; // GIVE ELEMENT SAME NAME AS THE <SELECT>
input.value = this.value; // ASSIGN THE VALUE FROM THE <SELECT>
form.appendChild(input);
} else { // IF IT'S NOT A SELECT ELEMENT, JUST CLONE IT.
$(this).clone().appendTo(form);
}
});
form.submit(); // NOW SUBMIT THE FORM THAT WE'VE JUST CREATED AND POPULATED
}
</script>
So what have we done here? We've given each row a unique id and included an element in the row that can trigger the submission of that row's unique identifier. When the submission element is activated, a new form is dynamically created and set up. Then using jQuery, we clone all of the elements contained in <td>'s of the row that we were passed and append the clones to our dynamically created form. Finally, we submit said form.
You can use the form attribute id to span a form over multiple elements each using the form attribute with the name of the form as follows:
<table>
<tr>
<td>
<form method="POST" id="form-1" action="/submit/form-1"></form>
<input name="a" form="form-1">
</td>
<td><input name="b" form="form-1"></td>
<td><input name="c" form="form-1"></td>
<td><input type="submit" form="form-1"></td>
</tr>
</table>
If you need form inside tr and inputs in every td, you can add form in td tag, and add attribute 'form' that contains id of form tag to outside inputs.
Something like this:
<tr>
<td>
<form id='f1'>
<input type="text">
</form>
</td>
<td>
<input form='f1' type="text">
</td>
</tr>
If all of these rows are related and you need to alter the tabular data ... why not just wrap the entire table in a form, and change GET to POST (unless you know that you're not going to be sending more than the max amount of data a GET request can send).
I cannot wrap the entire table in a form, because some input fields of each row are input type="file" and files may be large. When the user submits the form, I want to POST only fields of current row, not all fields of the all rows which may have unneeded huge files, causing form to submit very slowly.
So, I tried incorrect nesting: tr/form and form/tr. However, it works only when one does not try to add new inputs dynamically into the form. Dynamically added inputs will not belong to incorrectly nested form, thus won't get submitted. (valid form/table dynamically inputs are submitted just fine).
Nesting div[display:table]/form/div[display:table-row]/div[display:table-cell] produced non-uniform widths of grid columns. I managed to get uniform layout when I replaced div[display:table-row] to form[display:table-row] :
div.grid {
display: table;
}
div.grid > form {
display: table-row;
div.grid > form > div {
display: table-cell;
}
div.grid > form > div.head {
text-align: center;
font-weight: 800;
}
For the layout to be displayed correctly in IE8:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
...
<meta http-equiv="X-UA-Compatible" content="IE=8, IE=9, IE=10" />
Sample of output:
<div class="grid" id="htmlrow_grid_item">
<form>
<div class="head">Title</div>
<div class="head">Price</div>
<div class="head">Description</div>
<div class="head">Images</div>
<div class="head">Stock left</div>
<div class="head">Action</div>
</form>
<form action="/index.php" enctype="multipart/form-data" method="post">
<div title="Title"><input required="required" class="input_varchar" name="add_title" type="text" value="" /></div>
It would be much harder to make this code work in IE6/7, however.
If you can use javascript and strictly require it on your web, you can put textboxes, checkboxes and whatever on each row of your table and at the end of each row place button (or link of class rowSubmit) "save". Without any FORM tag. Form than will be simulated by JS and Ajax like this:
<script type="text/javascript">
$(document).ready(function(){
$(".rowSubmit").click(function()
{
var form = '<form><table><tr>' + $(this).closest('tr').html() + '</tr></table></form>';
var serialized = $(form).serialize();
$.get('url2action', serialized, function(data){
// ... can be empty
});
});
});
</script>
What do you think?
PS: If you write in jQuery this:
$("valid HTML string")
$(variableWithValidHtmlString)
It will be turned into jQuery object and you can work with it as you are used to in jQuery.
I second Harmen's div suggestion. Alternatively, you can wrap the table in a form, and use javascript to capture the row focus and adjust the form action via javascript before submit.
I had a problem similar to the one posed in the original question. I was intrigued by the divs styled as table elements (didn't know you could do that!) and gave it a run. However, my solution was to keep my tables wrapped in tags, but rename each input and select option to become the keys of array, which I'm now parsing to get each element in the selected row.
Here's a single row from the table. Note that key [4] is the rendered ID of the row in the database from which this table row was retrieved:
<table>
<tr>
<td>DisabilityCategory</td>
<td><input type="text" name="FormElem[4][ElemLabel]" value="Disabilities"></td>
<td><select name="FormElem[4][Category]">
<option value="1">General</option>
<option value="3">Disability</option>
<option value="4">Injury</option>
<option value="2"selected>School</option>
<option value="5">Veteran</option>
<option value="10">Medical</option>
<option value="9">Supports</option>
<option value="7">Residential</option>
<option value="8">Guardian</option>
<option value="6">Criminal</option>
<option value="11">Contacts</option>
</select></td>
<td>4</td>
<td style="text-align:center;"><input type="text" name="FormElem[4][ElemSeq]" value="0" style="width:2.5em; text-align:center;"></td>
<td>'ccpPartic'</td>
<td><input type="text" name="FormElem[4][ElemType]" value="checkbox"></td>
<td><input type="checkbox" name="FormElem[4][ElemRequired]"></td>
<td><input type="text" name="FormElem[4][ElemLabelPrefix]" value=""></td>
<td><input type="text" name="FormElem[4][ElemLabelPostfix]" value=""></td>
<td><input type="text" name="FormElem[4][ElemLabelPosition]" value="before"></td>
<td><input type="submit" name="submit[4]" value="Commit Changes"></td>
</tr>
</table>
Then, in PHP, I'm using the following method to store in an array ($SelectedElem) each of the elements in the row corresponding to the submit button. I'm using print_r() just to illustrate:
$SelectedElem = implode(",", array_keys($_POST['submit']));
print_r ($_POST['FormElem'][$SelectedElem]);
Perhaps this sounds convoluted, but it turned out to be quite simple, and it preserved the organizational structure of the table.
Tables are not meant for this, why don't you use <div>'s and CSS?
it's as simple as not using a table for markup, as stated by Harmen. You're not displaying data after all, you're collecting data.
I'll take for example the question 23 here: http://accessible.netscouts-ggmbh.eu/en/developer.html#fb1_22_5
On paper, it's good as it is. If you had to display the results, it'd probably be OK.
But you can replace it with ... 4 paragraphs with a label and a select (option's would be the headers of the first line). One paragraph per line, this is far more simple.
Is it valid to have a form tag inside a table tag? Some documentation links would be appreciated.
<form> is valid inside a <td> element. You can check this sort of thing at http://validator.w3.org. Choose "Validate by direct input", then paste the following HTML:
<table>
<tbody>
<tr>
<td><form action="test"><div><input type="text"></div></form></td>
</tr>
</tbody>
</table>
Under "More options", select "Validate document fragment". This allows you to check a HTML snippet without writing an entire page for it. I use it for checking HTML fragments all the time.
References:
The TD element
The FORM element
Putting a form tag inside a table (but outside the rows) was sometimes used to keep the margins of the form to interfere with the layout. It kind of works, but it's invalid code according to the HTML standard.
Use CSS to remove the margin from the form tag instead. Example:
<form ... style="margin:0">
Or preferrably put it in your style sheet.
You can nest a form within a td, its usually fine for most purposes though to wrap a form around a table
<form action="#">
<table>
<thead>
<tr>
<th>list</th>
<th>button</th>
</tr>
</thead>
<tbody>
<tr>
<td><input type="text" required="required"></td>
<td><button type="submit" id="saveRow">Save me</button></td>
</tr>
</tbody>
</table>
</form>
It is valid to put a <form> tag inside a <table> tag.
<table>
<tr>
<td>
<form name="sample" action="test.php">
<div>
<input type="submit" value="submit" >
</div>
</form>
</td>
</tr>
</table>
Editing note: tags wrapped as code so that the content reads as intended, but the answer should specify that while the form is inside the table, it cannot be a direct descendant: it must be a child of a cell.
