Dynamically Creates Page (form) Elements With The Option To Remove It
Feb 15, 2010
I have a function that dynamically creates page (form) elements with the option to remove it.
Code:
divcounter++;
var element = document.createElement("input");
...
element.onclick = function() {removeElement('sel' + String(divcounter))};
[Code]...
For some reason divNum in removeElement() always returns the latest value of divcounter. So if I add 4 form elements, and I want to remove the 2nd item, item 4 is removed and above fuction returns an error when I want to remove another element afterwards because it is trying to remove the 4th element again.
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.
I currently have a page which, when the user clicks a button creates a new row displaying a form. I also have other forms on this page how to close a form using javascript? My code to create the table row and form are below...
myform = document.createElement("form"); myform.method = "post"; myform.action = "editdetails.php"; myform.id = "editemail"; myform.name = "editemail"; var a=document.getElementById('editdetailstable').insertRow(2); var b=document.getElementById('editdetailstable').insertRow(3); [Code]....
When the user select an option in a dropdownlist, new dropdownlist elements are added dynamically using jquery. When a user clicks on a new option i the first dropdown, I want all the dynamically added events to be removed so that I can render new ones. But it seems the dynamically added events haven't been added to the DOM, so they cannot be removed. Is it possible to remove them? In that case, how? I've read a lot about .Live(), but my problem is not regarding an event - I just need to reach an element(?).
In IE the selection box is created, and there is a drop-down box if I click on the down arrow, but I can't see the OPTION text for each option. The options are invisible, yet the box seems fully functional. I went into the debugger and sure enough the selection box has "OPTION" child nodes with the correct "value" and "text" attributes.
So I have a table with rows and basically I cloned it and then appended it underneath another table. The user can click on the plus button to clone the table (which on the UI looks just like a row of fields) over and over. Next to the plus button I have a minus button that I want to use to remove the cloned table. Here's my code for the add table button:
Basically what I need to do is write functionality for the remove button that when clicked removes the bottom most table. Is there functionality in jquery where you can say "find last occurrence of 'addrow' and remove it onclick"? [code]...
I got a table with some select, inputs and textareas in it. if i click a button i execute addRow function which populates the row and creates new elements in each cell (new selects, inputs, textareas). But i dont know why, when i get a child of TD where select is the tagName is undefined and nodeName is #text, for INPUT and TEXTAREA it works perfect.
Some code
Code:
It happen so in Chrome and FF, in IE works fine (first time something that works here and doesnt in ff)
I have an entry form where a length needs to me entered. It can either be entered in meters (one input field) or feet and inches (two input fields).
I'd like to have the user select which units he wants to specify (with a selection tool) and then the form would automatically either display one text box or two.
I'm trying to get the value of a selected option value. I've tried using getElementById("fieldname").selectedIndex.value and formname.elements["fieldname"].options[selectedIndex].value with no joy.
The following code adds an element to a page when a new address is inputted. Is there a way to remove all added elements with a Clear All button? I have a "Clear All" button with id="ClearAddresses" but I don't know how to remove all created elements - the code here only removes one at a time, since the element is created when the "Search" button is clicked.
var Dom = { get: function(el){ if (typeof el === 'string') return document.getElementById(el); else return el; }, add: function(el, dest){ var el = this.get(el); var dest = this.get(dest); dest.appendChild(el); }, ..... setTimeout("add_visited_address();", 50); }
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'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;
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 have some JQuery that makes an Ajax call and then adds some rows to an existing table.
function LoadDestinationTable() { $("#destinationTable tr:gt(0)"[code]...
The problem is that the only place where the click event fires is on the rows that were added when the page was 1st rendered – the th, for example.I also tried adding an onclick event handler to the input button’s creation – that also does not fire.
I have an admin page in which I enter information for a Math Education website. I have to pre-load 10 video fields just in case a lesson has 10 videos. This is an over simplification:
[Code]...
What I would like to do is load 1 single video field and then have a button that when it is clicked automatically creates another field. I'm sure this is possible but everything I know I've learned from searching the internet and reading a few simple books so my knowledge is fragmented.
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'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].....
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 wanted to create something like: [URL] (this one looks horrible and only works on IE). And it's not difficult to make. But the difficult thing is that I want the design transmitted to a PHP page which creates a bitmap (using GD). The only solution I could think of is sending the x and y coordinates of each image in a POST request. How do I do that? Each browsers seems to render the "designer" page I've created a bit differently, so x and y coordinates are different in each browser.
I am currently working on a site as part of a student work term. One of the features of this site is the ability to upload a resume. The resume can have a arbitrary number of "work experiences". I have set up a form and want the user to be able to add new input elements with a click of a button. Here is a very pared down(for simplicity) version of the form:
I have cleated a bit of code that will dynamicly add a new line to a form so the use can add an infinat number of entires for this element.The code adds the form elemetns in IE and FF ok but when i click the submit button it does not submit the information from the dynamicly added elements in FF.Oddly enough IE works fine!Here is the code:
