Dynamically Created Form Elements Not Recognized By Request.Form?
Oct 21, 2010
I'm working with a form that has both static and dynamic form elements (add textbox, etc), and while I can access the static elements via request.form, the dynamic elements cannot be accessed. I have the dynamic elements appended within a div that lies within a table.
Here is the javascript:
Code:
function add3<%=strGoalCount%><%=strObjCount%>() {
var foo = document.getElementById('fooBar<%=strGoalCount%><%=strObjCount%>');
var numi = document.getElementById('theValue');
var num = (document.getElementById('theValue').value -1)+ 2;
I'm created a set amount of dynamic elements based on some elements in another form to try to submit them when the current form is submitted and this just doesnt work. It creates all the elements succesfully and puts in their proper names and values, but on the next page they are not available in $_POST in php.Here's the exact javascript I'm using, I tried appendChild and innerHTML,
Code: var elem = document.getElementById('submission_options').elements; for(var k = 0; k < elem.length; k++) {[code].....
My requirement is to submit html form with Attachment filesfor a web based email application.I have used javascript to achieve Attach more files functionality.When user clicks on ttach more files link, following HTML is dynamically generated using javascript:
<input type=file name=some_namesize=/>
The Javascript code is:
function addRow(tableID) { var table = document.getElementById(tableID); var rowCount = table.rows.length;
I have a grid that I'm adding rows to that include form text input boxes using addRowData. I know I can use the "editable:true" for that but I'd rather not at this time. Anyway I have the <div id=list1></div> surrounded by a <form></form>. Also statically I have a couple of text input boxes and a submit button. When I press the submit button the only parameters that show up in the POSTED data are the static ones. Is there a way to get the form elements "registered" with the form? I know I can always use javascript to extract the data and save it via an ajax call, but if there is a way to do it "correctly"
Example var myRow = {id:"0",call:"<input name='callt"+boxNo+"' id='call"+boxNo+"' class='calls' type='text'/>",amount:"<input name='amt"+boxNo+"' id='amt"+boxNo+"' type='text' value='"+defaultDep+"'/>",residual:"",calculate:"<input type='button' class='buttons' id='b"+boxNo+"'/>"}; $("#list1").addRowData(boxNo,myRow);
I am using a combination of php and Javascript to create forms that allow users to edit entries from a MySQL db.[code]The problem is that the form is not submitting. I think it has to do with the fact that the input fields are created dynamically.
I want to be able to access whatever the user types into my testCreation.html in a session created in testCheck.php. I then want that session to be accessed by testView.php. code...
what I am exactly trying to do is get data from a form, push that data into an array of objects and when a "display" button is clicked, to display the data in the form a div layer with a table in it for each object created. I have problems with dynamically creating the divs. Here's my code
I am analyzing header tags for submitting forms online in order to better understand how htmlhttp forms work- signing in to gmail, yahoo mail, and amazon, using the network tab of google developer tools, to view the http headers of requests and responses, and learn where they come from. I am seeing very peculiar behavior in my browser's (chrome)request headers when signing into amazon. The form data, always has the following two header names appended to the second and third to last places of the form data query: x=(some random number), and y=(some random number).
There are no input tags getting dynamically generated,since when i tell google chrome to break on all subtree modifications, the site still sends off the post with the added parameters before anything gets modified, BEFORE crashing. There also is NO ajax call which is causing dynamically added data to be appended to the form post.My question is this: is there any way, using javascript, to instruct a browser, to append data as data, to a form post, WITHOUT the use of dynamically appended input elements, or ajax?
As you can see in the "action" attribute, I'm calling this function:
function SubmitEditedInvoice(invno) { $.post('output.php?mode=6&invno=' + invno, $('#formEditInvoice' + invno).serialize(), function(output){[code]....
The problem I'm having is that no data is passed to the PHP back end. I have verified that the variable invno is correctly passed to the javascript function, and have tested my .serialize() by using a hard-coded form ID, but I still get no data passed through.
The link below is a stripped down section of a form.
[url]
The problem I'm having is with altering the names of the fields. I'm trying to add an identifier on the end. "_X_1", "_X_2" after the new sections are added.
NOTES:
Incidentally, "_X_" is a delimiter so the key can be converted into an array on the back end to extract data from it.
I can't alter the "repeater" variable because it would be extremely complicated on the back end.
I have a form that has a table that adds rows dynamically, 4 columns with each having a form element. i end up with the following when the page loads, created dynamically:
The code below will add new form elements when ever I click the add button. However when you add more elements the combo box element goes out of alignment.
multientry.js function addValue(divname){ var newdiv = document.createElement('div'); newdiv.innerHTML = "<BR><INPUT TYPE='text' name='index1'>";
Code: Is this something that is better suited for Javascript/DHTML or AJAX? I have not been able to find any tutorials on how to do this. Can anyone give any suggestions? I am very new to both Javascript, and of course AJAX, since with out Javascript there is no AJAX.
I'm trying to write a script for a website that reads from a database and makes a separate table for each entry in the database. Since the number of entries can change, I want to dynamically create a div for each one, which I can later hide or display based on user selection. However, when I try to access the dynamically created elements by their ID, they return null. Is what I'm trying to do here actually possible?
for(var i = 0; i < tables.length; i ++) { var newDiv = document.createElement("div"); newDiv.setAttribute("id", tables[i].name); newDiv.setAttribute("name", tables[i].name); newDiv.setAttribute("class", "hidden");
I am creating textboxes dynamically using the following code:
[Code]...
I want to have a function that will remove textboxes and the newline that is created. I have the following function to remove the text boxes but I cant remove the new lines that were created so an empty space is left on the page.function RemoveElement() {
var d = document.getElementById('spanManualInput'); var oldbox = document.getElementById('Value'+i); d.removeChild(oldbox); d.removeChild('br'); }
And I doing some validation like this. function checkvalue() { var f = document.forms['formA']; var eLen = f.elements.length; for (var i=0; i<eLen; i++) { if(f.elements[i].name == "text_" + i) { alert ( f.elements[i].name); } else { alert (f.elements[i].name); } }
It never goes into first part of if statement.. Is there a way I can access these kind form elements..
So, what I want to happen is that there is an add vehicle link or button so that when someone hits it, it allows them to add in another vehicle. Of course it should also add some index to the id's of all the inputs as I will use the post data to add the vehicles to a database.
Now at first I thought I had found a solution, that works a little bit. But then when the PHP comes into effect things break.
Also, this is an aside: the truck vin row is controlled by jquery now. If the plan type selected is for a truck, it will show that row, if it's not then that row is hidden. I'm pretty sure I'll need to build a loop in the Jquery script that will allow that hide and show feature to work based on the index added to the truck row.
in my searching, the only thing I've really been able to find is that I might have to use AJAX, but that's not something I familiar with just yet.
I have form that asks a simple question: "How many XYZs do you want to create?" Then, for every XYZ, it should create several new labels/inputs in the form.
That is, every XYZ looks like this: <div id="xyz"> <label>Whatever</label> <input> blah blah blah </input </div>
I looked into .each() and .live(), but I can't wrap my mind around how to do this.
It works perfectly but I need to add more fields than stated in the post. If I add in another field, only one field gets the increment. The other doesn't. Eg.
I am trying to insert and remove form element dynamically. What I was doing was some sort of recipe program where a user can prefer to add for elements as he/she is done inputting a recipe. He/She can also remove the ingredient if he/she opts to. Here is the link: [URL]
I already solved the problem but I am not sure if what I did is an efficient one. The thing I did was clone the first child of the form. But I realized that if I would put text inside the first child of the for, the duplicate field will also contain the same text as the first child which I don't want to happen. This is why, I set the display of the first child of the form as none. I am not sure if this would cause some problem when I would submit the whole form so that the inputs will be saved in the database since the first child is empty. I was thinking that as the form will be submitted, I would just remove the first child.
Is there a way to access a form element that was created using AJAX?I've had no luck when using 'document.getElementById( elementID )' as the element doesn't appear to be recognised.
I can see the raw HTML in firebug etc, but the dynamic elements (the ones created by jquery for example), obviously don't appear there. I struggle referencing some of them - Ideally I'd like to be able to trigger a display showing what handle to use for any given element - for example by clicking on them.
Previously when developing my own modal windows I have been creating a "mask" div directly in my markup, in the CSS setting it to be display:none and then setting it to show() by jQuery when a button is clicked.
I'm sure there is a better way to do this but i'm getting a little stuck.
I tried adding the "mask" div and its content to the body using prepend() when my button is clicked but i found i then can't select any of the added elements in jQuery.
How can you select elements you have added to a page by jQuery?? Also if this is the right approach whats the best way to insert a block of html to a page??
